Asphalt
Asphalt Shingles (Architectural)
The standard choice for pitched sections on Philly homes. Algae-resistant versions recommended due to regional humidity. Ice and water shield at eaves is code-required.
- Most affordable option for pitched roofs
- Wide contractor availability in Philadelphia
- Many color and style options
- Proven performance in freeze-thaw cycling
- Not suitable for low-slope/flat sections common on row homes
- Shorter lifespan than metal or slate
- Dark colors absorb significant summer heat
TPO
TPO Membrane
Increasingly popular on Philly flat roofs. White reflective surface reduces cooling costs. Heat-welded seams are more reliable than adhesive-bonded systems in freeze-thaw conditions.
- Excellent energy efficiency (white reflective surface)
- Heat-welded seams resist freeze-thaw cycling
- Good lifespan for the cost
- Lightweight, reducing structural load on older homes
- Requires skilled installer for proper seam welding
- Newer product with less long-term track record than EPDM
- Puncture-prone if exposed to foot traffic

Choosing the Right Roofing Material in Philadelphia
Philadelphia’s climate presents unique challenges for roofing materials. Freeze-thaw cycles through winter, humid summers, and occasional nor’easters mean your roof material needs to handle temperature extremes, moisture, and high winds. The right choice depends on whether your home has a flat roof (common on row homes) or a pitched roof, your budget, and how long you plan to stay.
For flat roofs on Philadelphia row homes, the most common choices are TPO membrane, EPDM rubber, and modified bitumen. TPO has gained popularity for its energy efficiency and heat-welded seams, while modified bitumen remains a proven budget-friendly option with decades of local track record.
For pitched roofs, architectural asphalt shingles offer the best value, while standing seam metal provides superior longevity. Homeowners in historic districts should check with the Philadelphia Historical Commission before choosing materials, as some areas require natural slate or other historically appropriate options.
