Local Climate & Its Impact on Roofs
Canonsburg's Seasonal Climate
- Four distinct seasons drive roof maintenance in Canonsburg: cold, snowy winters; hot, humid summers; and frequent spring/fall rain.
- The humid continental pattern means rapid temperature swings can stress roofing materials.
- Proximity to hills and the Pittsburgh metro area affects wind, shade, and moisture exposure, influencing algae, moss growth, and shingle aging.
Winter: Snow, Ice, and Freeze-Thaw
- Freeze-thaw cycles push water into tiny roof cracks and gutters, then freeze, widening gaps and accelerating wear.
- Ice dams at eaves are a common risk when attic insulation or venting is inadequate, leading to interior leaks and ceiling damage.
- Icicles and wind-driven snow can damage vents, flashing, and shingles during storms.
What this means for your roof:
- Promote attic air flow and insulation to minimize ice dam risk.
- Keep gutters and downspouts clear so melted snow can drain away.
Steps to manage winter risks:
1) Ensure attic insulation and ventilation meet or exceed local climate needs.
2) Clear gutters before and after heavy snow events.
3) Use a roof rake from the ground to remove excess snow along the eaves safely.
4) If ice dams form, avoid aggressive chopping; consider professional assessment and, if needed, heated cable solutions installed by a licensed pro.
Warnings:
- Ice damming can cause interior leaks and structural damage if left unaddressed.
- Ice and snow loads vary with roof design; consult a roofer if you notice sagging or cracking.
Summer: Heat, Humidity, and UV
- Strong sun and high humidity accelerate granule loss on asphalt shingles and increase attic heat if ventilation is poor.
- Intense sun can cause fading and edge curling on some roofing materials.
What this means for your roof:
- Adequate attic ventilation reduces heat buildup and extends shingle life.
- Consider reflective or cool-roof options if you're re-roofing, and ensure underlayment and flashing are in good condition.
Steps to manage summer risks:
1) Inspect for curled or cupped roof edges after hot spells.
2) Verify attic insulation and ventilation are balanced to limit heat transfer.
3) Keep trees trimmed so shade isn't excessive on shingles, which can promote moss in damp spots.
Wet Weather, Wind, and Storms
- Spring and summer bring thunderstorms, occasional hail, and strong winds that can lift shingles or damage flashing.
- High winds can expose fasteners and seams; hail can dent or crack softer materials.
What this means for your roof:
- Regularly inspect flashing, vent boots, and ridge caps after storms.
- Look for lifted or missing shingles, torn underlayment, or damaged gutters.
Steps to stay ahead:
1) After any severe storm, perform a quick rooftop and attic check or schedule a pro inspection.
2) Maintain sealant around vents, chimneys, and skylights.
3) Replace damaged shingles promptly to prevent leaks and further moisture intrusion.
Trees, Debris, and Moss
- Canonsburg neighborhoods often have mature trees nearby; leaves, needles, and branches accumulate on roofs and in gutters.
- Shaded, damp areas promote moss and algae growth, which can retain moisture and lift shingles over time.
What this means for your roof:
- Debris removal and gutter cleaning are essential to prevent moisture retention and rot.
Steps to manage debris:
1) Trim branches that overhang the roof and gutters.
2) Clean gutters at least twice a year and after heavy storms.
3) Consider moss-control methods compatible with your roof material, and consult a pro for persistent growth.

- Dormers (and shed dormers): Create usable attic space, improve light, and break up large roof planes for better curb appeal on bungalows and Cape Cods.
- Modern combinations: Many homes mix roof lines (gables with hips, or flat accents) to refresh a classic shell without losing neighborhood character.
Materials That Suit the Canonsburg Climate
- Asphalt shingles (standard): Most common choice for cost, availability, and decent lifespan. Wide color and texture options help match Canonsburg's varied architectural styles.
- Architectural (laminated) shingles: Thicker, more textured appearance with better weather resistance; boost curb appeal on brick, stone, or wood façades.
- Metal roofing: Steel or aluminum, in standing-seam or center-ridged profiles; excellent for long life, superior snow shedding, and a contemporary look that pairs well with modern updates.
- Slate and synthetic slate: Authentic look with lighter weight than natural slate; ideal for historic homes or high-end remodels, though synthetic options can be more budget-friendly.
- Cedar shakes: Rustic, natural charm for Craftsman and lodge-influenced homes; requires regular maintenance and protection against moisture and pests.
- Tile (concrete/ceramic): Durable and heavy; not common in all Canonsburg neighborhoods due to weight and cost, but seen on select traditional or Mediterranean-inspired façades.
Architectural Trends in Canonsburg Homes
- Colonial Revival influence: Symmetry, brick or stone exteriors, and traditional rooflines with emphasized gables or dormers; pairs well with strong, durable roofing materials.
- Craftsman/Bungalow revival: Low-pitched roofs, wide overhangs, exposed rafter tails, and mixed siding or stone accents; often paired with natural-looking shingles or shakes.
- Traditional with modern updates: Classic shapes blended with modern materials—dark shingles, metal accents, and mixed textures (brick/stone with siding) for updated curb appeal.
- Historic restoration focus: In older sections, homeowners opt for synthetic slate or carefully matched shingles to preserve silhouette while improving durability and longevity.
- Energy-conscious upgrades: Cool or reflective shingles, better ventilation, and upgraded insulation under the roof deck to combat Canonsburg winters and humidity.
Practical Considerations for Canonsburg Homeowners
1) Align roof style with the home's architecture to protect resale value and harmony with nearby houses.
2) Factor in snow load and drainage; ensure adequate pitch, proper valleys, and ice-dam prevention measures.
3) Prioritize attic ventilation and insulation to extend roof life and improve year-round comfort.
4) Budget for long-term performance: warranty terms, maintenance needs, and potential future repairs.
5) Hire a local Canonsburg roofing professional who understands regional codes, climate, and historical context.
Historic Districts and Restoration
- For older Canonsburg residences, preserve the roofline's proportion and character; when replacing, consider synthetic slate or rubber shingles that mimic the look with heavier durability and lighter weight.
- Match colors to brick or stone façades, leaning toward charcoal, dark gray, or deep blue hues that complement historic masonry.
- Coordinate with local guidelines for any preservation requirements and ensure contractor familiarity with period-correct silhouettes and detailing.
Average Roofing Costs in Canonsburg
Typical Material Cost Ranges in Canonsburg
- Asphalt shingles (standard 3-tab): $3.50-$6.50 per sq ft; about $350-$650 per square.
- Architectural shingles: $5.50-$8.50 per sq ft; about $550-$850 per square.
- Metal roofing: $8-$12 per sq ft; about $800-$1,200 per square (premium metals can run higher).
- Slate: $15-$40+ per sq ft; roughly $1,500-$4,000+ per square.

- Wood shingles/shakes: $6-$9 per sq ft; about $600-$900 per square.
Local Considerations That Shift Costs
- Climate and drainage: Pennsylvania winters and snow require ice/water shield in eaves and valleys, adding material and labor.
- Style and architecture: Canonsburg's mix of brick colonials, ranch homes, and dormered designs means more flashing around chimneys, skylights, and valleys, which increases time and waste.
- Roof geometry: multiple gables, dormers, and steep pitches raise labor hours by roughly 10-30%.
- Permits and disposal: local permit fees and landfill charges apply; removal and disposal of old material can change the baseline.
- Access and safety: tight driveways or limited yard space can require extra scaffolding or crane time, nudging crew rates upward.
- Local labor market: prevailing wage trends in the Pittsburgh metro area influence bids and timelines.
Impact of Roof Size, Pitch, and Access
- Size: smaller roofs under 15 squares tend to be on the lower end; mid-size homes (15-25 squares) fall in the typical range; larger 30+ squares gain efficiency but demand more crew days.
- Pitch: steeper roofs add 10-25% to the installed price due to safety gear, longer setup, and slower progress.
- Access: easy multi-story access reduces complexity; complex access (end-of-row houses, narrow yards) can add 5-15%.
Common Add-Ons That Change the Bottom Line
- Tear-off vs. layover: full tear-off adds $1,000-$3,000 depending on size and disposal, while a layover is often limited by code and roof condition.
- Underlayment and ice/water shield: $0.50-$1.50 per sq ft above basic coverage.
- Flashing, valleys, pipes, and chimney details: $50-$350 per detail depending on complexity.
- Ventilation upgrades: $150-$500 for new attic vents, baffles, or ridge vents.
- Inspections and warranties: upgrading to longer or higher-quality warranties can add 0-8% to total.
Quick Cost-Estimate Steps
1. Measure the roof area: 1 square equals 100 sq ft; tally total squares and pick material.
2. Decide on tear-off vs. layover: factor disposal fees and potential scaffolding.
3. Compare bids with consistency: ensure each bid includes permits, disposal, underlayment, flashing, ventilation, and a clear warranty.
Permits & Local Regulations
Do I need a permit to re-roof in Canonsburg?
- In Canonsburg Borough, a building permit is typically required for roof replacement.

- Hire a licensed, insured contractor and ensure they are prepared to provide the necessary permit documentation.
- Keep a copy of all permits, approvals, and inspection reports on-site during the project.
- If you're unsure whether a change requires a permit (e.g., new skylight, venting, or chimney work), ask the Building Department in advance to avoid surprises.
Common questions
- Can I issue the permit in my name if I'm doing the work myself? Check Canonsburg's rules; some jurisdictions allow homeowners to pull permits, while others require a licensed contractor.
- Do I need a separate permit for electrical work related to the roof? Often yes; verify with the Building Department and your electrician to ensure all permitting is properly coordinated.
Common Roofing Problems in Canonsburg & Solutions
Wind Damage and Missing Shingles
Canonsburg experiences seasonal wind gusts that can lift loose shingles and expose the underlayment. This is especially common after storms or heavy winds.
Signs
- Missing, curled, or buckled shingles along the roof edges or ridgelines
- Shingle granules in gutters or downspouts
- Visible gaps or exposed decking on the roof surface
Solutions
1. Do a careful roof-side check from the ground or with a stable ladder. Note damaged areas without stepping on fragile spots.
2. Replace missing or damaged shingles with matching ones. Re-nail with proper pattern and corrosion-resistant nails; seal seams if needed.
3. Inspect underlayment and decking for damage and replace as necessary.
4. Consider wind-resistant upgrades (hurricane clips, sealed ridge vent, and proper flashing) and schedule professional repairs for extensive uplift.
Leaks Around Vents and Flashing
Flashing around roof penetrations (vents, chimneys, pipes) can fail over time, especially in Canonsburg's freeze-thaw cycles.
Signs
- Ceiling stains or damp insulation near vents
- Dark streaks along vent boots or flashing
- Cracked, cracked-open, or loose flashing and nails
Solutions
1. Inspect vent boots and step flashing for cracks or gaps.
2. Remove old sealant and reseal with a flexible, compatible sealant; reflash where needed.
3. If flashing is corroded or damaged, replace the flashing or vent boot and reseal securely.
4. After repairs, test with a gentle water spray from the inside of the vent to confirm you've stopped leaks; call a pro if leaks persist.
Ice Dams and Snow Load Issues
Cold Canonsburg winters can create ice dams, causing water to back up under shingles and into the attic.
Signs
- Icicles forming at eaves and gutters
- Water stains or damp spots on ceilings near the outer walls
- Frost or condensation buildup on the attic side of the roof
Solutions
1. Improve attic insulation and seal air leaks to keep warm air from escaping into the attic.
2. Enhance ventilation (soffit intake with ridge/roof vents) to maintain a cold roof deck.
3. If necessary, use heat cables on eaves as a last resort and in compliance with local codes.
4. Clear snow from the roof with a plastic roof rake—never use metal tools that can damage shingles.
Moss, Algae, and Roof Mold
Shaded, damp areas breed moss and algae, which can lift shingles and trap moisture.
Signs
- Dark streaks or green patches on the roof
- Soft, spongy feel or lifting shingles in shaded spots
Solutions
1. Clean with a roof-safe, non-pressurized cleaner; avoid high-pressure washing that can damage shingles.
2. Trim overhanging branches to reduce shade and moisture retention.
3. Install zinc or copper strips along the ridge to inhibit new growth.
4. If damage is extensive, replace severely affected shingles and address underlying moisture issues.
Gutter, Fascia, and Drainage Problems
Clogged gutters and rotted fascia can cause water to back up under shingles and attack the roof edge.
Signs
- Water overflowing gutters during rain
- Sagging or loose gutters and loose or rotted fascia boards
- Water pooling near the foundation due to poor drainage
Solutions
1. Clean and flush gutters and downspouts; ensure proper slope for drainage.
2. Re-secure hangers and brackets; replace any damaged sections.
3. Replace rotted fascia boards and reseal or repaint.
4. Install gutter guards to reduce debris and maintain flow; verify downspouts direct water away from the foundation.
Attic Ventilation and Insulation
Poor attic ventilation or insufficient insulation accelerates wear and invites ice dams and moisture problems.
Signs
- Hot, stuffy attic and high energy bills
- Condensation or mold in the attic
- Evidence of moisture in rafters or decking
Solutions
1. Inspect insulation depth and seal gaps around attic penetrations.
2. Add or upgrade soffit and ridge vents to balance airflow.
3. Increase insulation to local recommendations.
4. Reassess after a season of use to ensure proper ventilation and moisture control.
Maintenance & Repair Tips for Canonsburg
Annual Inspection Checklist
- Inspect the entire roof surface for damaged, curled, blistered, or missing shingles. In Canonsburg's freeze-thaw cycles, fast-moving wind gusts can lift edges and loosen tabs.
- Check flashing around chimneys, vents, skylights, and along valleys. Look for rust, gaps, or loose sealant and reseal or replace as needed.
- Look for signs of water intrusion in ceilings or walls inside the attic and upper floors. Stains, frost, or musty odors can indicate hidden leaks.
- Inspect attic insulation and ventilation. Ensure soffit vents, ridge vents, and roof vents are clear and that insulation isn't compacted or damp.
- Clean gutters and downspouts, and ensure drainage away from the foundation. Blocked systems can cause ice damming and water infiltration.
Seasonal Maintenance by Season
- Spring
- Remove pine needles, leaves, and debris from the roof and gutters. Debris traps moisture and can accelerate rot.
- Inspect for wind damage after strong storms and repair or replace damaged shingles promptly.
- Check moss or algae growth; treat with a safe roof-cleaning solution and rinse thoroughly.
- Summer
- Trim overhanging branches to reduce shade and limit moisture retention on the roof surface.
- Verify attic ventilation remains unobstructed; re-rout or reseal soffit or ridge vents if you notice hot spots.
- Schedule a professional inspection if you notice curling edges or granule loss from heat exposure.
- Fall
- Clear gutters and downspouts again as leaves shed; ensure they drain away from the house.
- Inspect and reseal around vent pipes and skylights before winter.
- Look for missing granules and use a shallow broom to sweep debris from the roof surface without scrubbing.
- Winter
- Monitor for ice dams; ensure the attic is well insulated and ventilated to minimize melt-and-refreeze cycles.
- Safely remove icicles and snow near the eaves to reduce overhead weight and potential leaks.
- Avoid walking on icy roofs; if you must, distribute weight evenly and use proper footwear and a harness if needed.
Common Local Issues in Canonsburg
- Ice damming during cold snaps due to uneven attic insulation and ventilation.
- Moss or algae buildup on shaded or north-facing roof surfaces.
- Tree limbs overhanging the roof can rub shingles or cause debris accumulation in gutters.
- Freeze-thaw cycles that cause hairline cracks in shingles or flashing over time.
Do-It-Yourself Repairs: Simple Fixes
1) Replacing a single damaged shingle
- Safely set a stable ladder and wear gloves and eye protection.
- Lift the damaged shingle gently and remove surrounding nails with a flat bar.
- Slide a new shingle into place, aligning its tabs with neighboring shingles.
- Nail through the predrilled holes and seal surrounding nails with roofing cement.
2) Sealing minor flashing gaps
- Clean the area and apply a flexible exterior sealant compatible with metal flashing.
- Smooth with a putty knife and ensure a tight seal to prevent water entry.
3) Clearing a clogged gutter section
- Use a small plastic scoop to remove debris from the gutter inside, then flush with a garden hose.
- Check downspouts for obstructions and remove any blockages with a plumber's snake if needed.
Gutter & Drainage Maintenance
- Keep gutters free of leaves and sediment; maintain a slight slope toward downspouts for proper drainage.
- Install gutter guards or screens to reduce debris buildup in Canonsburg's leafy seasons.
- Ensure downspouts extend at least 4–6 feet away from the foundation to prevent pooling near the house.
- Inspect fascia boards for signs of rot or water staining after heavy rains or snowmelt.
When to Call a Professional
- You notice significant curling, widespread granule loss, or widespread shingle failure.
- Flashing around chimneys, vents, or skylights is loose, rusted, or leaking.
- You're unsure about safe ladder use or roof access, or the roof slope is steep.
- There are persistent leaks inside the attic after several weather events.
Safety First
- Always work with a buddy or hire a pro for steep or high-sloped roofs.
- Use proper fall protection, sturdy ladders, and non-slip footwear.
- Avoid power washing the roof, which can damage shingle granules and flashing.
When to Repair vs. Replace
Quick rule of thumb
- Repair if damage is localized, the roof is relatively young, and shingles aren't severely cupped or curling.
- Replace if damage is widespread, multiple leaks persist, or the roof is near or past its expected life (think 20–25 years for asphalt shingles, longer for architectural styles).
Age, warranty, and life expectancy in Canonsburg
- Asphalt strip (3-tab): roughly 20–25 years under typical Pittsburgh-area conditions.
- Architectural asphalt: about 25–40 years with proper maintenance.
- If your Canonsburg roof is around or beyond these ranges, a full replacement often makes more sense than repeated patches, especially in face of winter ice dams and heavy snowfall.
Signs that call for a repair
- Localized leaks around flashing, chimneys, dormers, or vents.
- A small patch of missing or damaged shingles that can be fixed without redoing large sections.
- Granule loss in a few spots but intact underlayment and roof deck.
- Consistent weather-tightness after a targeted repair and no ongoing water intrusion.
Signs that call for a replacement
- Widespread shingle damage: curling, cupping, extensive granule loss across many shingles.
- Sagging sections, soft decking, or visible structural concerns.
- Recurrent leaks despite multiple patches or flashing replacements.
- Roof nearing the end of its service life and replacement would improve insulation, ventilation, and energy efficiency.
Cost considerations and ROI in Canonsburg
- Repairs: typically a few hundred to a couple thousand dollars, depending on the scope (patches, flashing work, gutter integration, etc.).
- Replacement: often several thousand to well into the tens of thousands, influenced by roof size, material choice (asphalt, metal, etc.), and removal/disposal needs.
- In Canonsburg, a well-timed replacement can improve curb appeal, insulation, and long-term energy costs, especially when winters push ice dam risk and heat loss.
Material and climate considerations for Canonsburg homes
- Asphalt shingles remain the most common, with architectural shingles offering longer life and better resistance to wind and heat cycling.
- Snow and freezing temperatures in southwestern PA stress flashing, valley linings, and attic ventilation; replacing with a roof that has upgraded underlayment and proper ventilation can reduce future repair frequency.
- If you have unique materials (slate or metal) or older underlayment, the decision leans toward replacement when repairs become frequent and the deck or underlayment show age.
Step-by-step decision guide
1. Inspect age and material: note shingle type, last major repair, and approximate roof age.
2. Assess damage pattern: is it confined to a small area or spread across the roof plane?
3. Check attic/ventilation: are insulation and venting adequate to prevent ice dams and condensation?
4. Estimate costs: get a rough repair quote for patches vs. a full replacement estimate.
5. Decide with perspective: if patches would be frequent and expensive, replacement often offers greater value and peace of mind.
What to look for during a professional assessment (Canonsburg-specific)
- Chimney and vent flashing condition, as Canonsburg homes often have multiple vent openings.
- Valley wear, especially where snow and meltwater travel.
- Gutter and downspout backups that may mimic or exacerbate leaks.
- Deck and decking health under damaged areas; soft spots indicate more than surface repairs.
Quick maintenance to extend life (Canonsburg)
- Keep gutters clear to prevent water backup and ice buildup.
- Improve attic insulation and ensure proper ventilation to reduce ice dam risk.
- Schedule regular inspections after heavy snows or storms to catch issues early.
When to Hire a Professional
- You see active leaks, dripping, or ceiling/wall staining inside after rain or snowmelt.
- Shingles are cracked, curled, torn, or missing, especially after a storm.
- Damaged flashing around vents, chimneys, or skylights is visibly creased or detached.
- Granules in gutters or downspouts indicate worn asphalt shingles.
- Ice dams form along the eaves, squeezing under shingles or causing staining on interior ceilings.
- The roof area feels unstable or you hear creaking from high winds or heavy snow.
Weather-driven and safety considerations for Canonsburg
- Canonsburg's winter weather can rapidly stress roofs with freezing and thawing cycles; wind and snowfall can lift loose shingles and expose underlayment.
- Working on a steep pitch or near power lines requires fall protection and proper equipment—best left to a pro.
- If your roof is aging (typical asphalt shingle life is 15–25 years, depending on quality and climate) or damaged by hail, a pro can assess whether repair or replacement offers the best value.
- If there's any sign of mold, widespread water damage, or structural sagging, professional assessment is essential for safety and building code compliance.
Should you repair or replace in Canonsburg?
- Local weather realities and aging materials often favor a full roof replacement when damage is widespread, underlayment has failed, or flashing needs extensive work.
- For isolated issues (a handful of damaged shingles, small leaks), a targeted repair may be cost-effective—though a pro can help you weigh long-term durability and warranties.
- If you're considering more efficient materials or upgrading for better ice dam resistance and insulation, a pro can design a solution suited to Canonsburg's climate.
How to evaluate a Canonsburg roofing contractor
- Licenses and insurance: Ask for current general liability and workers' compensation coverage; verify with the insurer and state/local authorities.
- Local reference checks: Request a minimum of 3 Canonsburg-area references and follow up on recent work.
- HICPA and local requirements: Ensure the contractor is compliant with Pennsylvania's home improvement protections (proper contract terms, cancellation rights, and project scope documentation) and that any Canonsburg-specific permit requirements will be handled.
- Permits and inspections: Confirm the contractor will pull the necessary permits and coordinate inspections with the city/county.
- Warranties and materials: Get details on manufacturer warranties, workmanship warranties, and what is covered if issues arise.
- Detailed written estimate: Compare scope of work, materials, roof deck prep, underlayment, fasteners, flashing, venting, cleanup, and timeline.
- Subcontractors and safety: Ask who will perform the work and whether they use subcontractors; verify safety plans and site protection.
- Past performance: Look for stability in the local market (years in business, consistent crew), and read Canonsburg neighbor reviews.

Putting A Lid On It: Roof Maintenance, Repair, and Replacement in Canonsburg
Canonsburg's roof lives through four distinct seasons, with winter snows, spring rain, hot summer sun, and autumn winds testing every seam. The town's mix of shade from mature trees and occasional heavy storms means small issues can grow quickly if left unchecked. Regular upkeep protects your home from leaks, drafts, and ice dam damage, saves money over time, and keeps your roof looking and performing its best for years to come.
What makes Canonsburg unique is less about fancy materials and more about how we live with weather and trees. Proper attic ventilation, solid flashing, and clear gutters are your frontline defenses against moisture intrusion. A well-maintained roof not only shields your family but also preserves the value and curb appeal of your home in a community that takes pride in its neighborhoods.
Seasonal maintenance snapshot
- Spring: after the winter, inspect for damaged shingles, loose flashing, and granule loss. Clean fallen debris from gutters and downspouts; ensure water flows away from the foundation.
- Summer: check for heat-related wear like blistering or soft spots on the decking. Trim back overhanging branches to reduce future debris and branch damage.
- Fall: schedule a thorough inspection before winter. Clean gutters one final time, seal gaps, and verify attic insulation and ventilation to prevent ice dams.
- Winter: remove loose snow near skylights or vents carefully and avoid climbing on a icy roof. If ice dams form, contact a professional to address insulation, ventilation, and potential roof edge issues.
Short checklist for homeowners
- Inspect the roof from ground level after storms for missing shingles or flashing damage.
- Keep gutters clean and downspouts clear; ensure splash blocks direct water away from the foundation.
- Maintain attic insulation and verify a clear, unobstructed airflow from soffits to vents.
- Look for curled, cracked, or faded shingles and any signs of moisture inside the attic or ceilings.
- Schedule professional audits as soon as you notice leaks, sagging, or persistent moisture.
When to call a pro
- Visible leaks, ceiling stains, or soft decking
- Loose or missing shingles, damaged flashing, or chimney/vent leaks
- Widespread hail damage, high-wind damage, or after a major storm
- Persistent ice dam formation or condensation issues despite basic maintenance
Lifespan and replacement notes
- Asphalt shingles typically last 15–30 years depending on quality and climate
- Metal roofs offer durability with longer lifespans but require proper installation and flashing
- Tile and slate demand specialist installation and can be more costly but long-lasting
