Frequently Asked Questions

Which brand lasts longer in Philadelphia’s climate?

Both GAF and CertainTeed shingles typically last 25-30 years in Philadelphia’s climate when properly installed. GAF’s higher copper content in StainGuard technology provides slightly better long-term algae resistance, which can extend the roof’s aesthetic lifespan by 2-3 years in humid areas like Wynnefield.

Do I need special underlayment for Philadelphia winters?

Yes. Philadelphia building code requires ice and water shield in valleys, around chimneys, and along eaves where ice damming occurs. Both GAF and CertainTeed require this underlayment for warranty compliance. The shield prevents water infiltration when melting snow refreezes at the roof edge.

Can I install these shingles over my existing roof?

Philadelphia code allows one layer of roofing material. Installing over existing shingles is possible but reduces the new roof’s lifespan and may void warranties. A complete tear-off allows inspection of the roof deck and ensures proper underlayment installation, which is crucial for warranty coverage.

How long does installation take in Wynnefield?

Most single-family homes in Wynnefield require 2-3 days for complete installation. Rowhomes with limited access may take 3-4 days due to material handling constraints. Weather delays are common in Philadelphia’s spring and fall seasons, so contractors typically schedule a 5-7 day window for completion.

What permits are required for roof replacement?

Philadelphia L&I requires a roofing permit for all replacements. The permit costs $250-$450 depending on roof size and ensures compliance with local building codes. Your contractor should handle permit acquisition and schedule required inspections during and after installation..
