Flat Roof Repair and Rubber Roofing in Philadelphia
Rubber (EPDM) and modified bitumen roofs, flat roof repairs and ponding fixes for Philadelphia row homes, twins and garages.
Flat roof repair and replacement for Philadelphia homes
The rear roof on most Philadelphia row homes is flat or nearly flat, and it is a big part of what Discounted Roofing LLC does. We repair leaks and ponding, replace worn flat roofs with new rubber (EPDM) or modified bitumen, and reseal and coat flat roofs to extend their life.
Every flat roof job includes the joints where the roof meets parapet walls, chimneys, skylights and drain boxes, because those are where flat roofs usually fail.

Flat roofing services
Flat roof repair
Cracks, open seams, blisters and failed flashing, patched with commercial-grade roofing cement reinforced with fabric mesh.
Ponding water fixes
Low spots that hold water are built up so the roof drains, then sealed so the water has nowhere to get in.
Rubber (EPDM) roof installation
A single-ply rubber membrane in large sheets with few seams. A common choice for row home rear roofs.
Modified bitumen roofs
Asphalt-based roll roofing with a tough surface that stands up to foot traffic.
Drain boxes, scuppers and downspouts
New drain boxes, including copper, and downspouts so water leaves the roof. See gutters and downspouts.
Resealing and coating
A sound flat roof can be resealed and silver-coated instead of replaced. See roof coating.
Why flat roofs leak in Philadelphia
Water sits on a flat roof longer than on a pitched one, so every weak point gets tested. The usual culprits here are ponding in low spots, flashing pulling away from brick parapet walls, skylight and hatch curbs, clogged drain boxes, and the seam where your roof meets your neighbor’s on a shared row.
Old coatings dry out in summer heat and crack through freeze and thaw. Catching those problems early is often the difference between a reseal and a new roof.
Rubber or modified bitumen?
Rubber (EPDM)
Large single-ply sheets with few seams, flexible in cold weather, and a good fit for long row home rear roofs.
Modified bitumen
Layered asphalt-based rolls with a granulated or coated surface that handles foot traffic well.
Which is right for you
We decide after checking the existing layers, the slope and drainage, and how you use the roof, then explain the choice with photos.

Frequently asked questions
What is the best fix for a leaking flat roof?
Find where the water gets in first. Most flat roof leaks start at flashing, seams, drains or ponding spots. A small area can be resealed with roofing cement and fabric mesh; widespread wear calls for a new membrane.
How long does a rubber roof take to install?
A row home rear roof can often be done in a day, weather permitting; one customer wrote that their new rubber roof was finished in under 24 hours. Larger roofs or jobs with deck repairs take longer.
Why does water pond on my flat roof?
Low spots form where the deck has sagged or layers are uneven, and clogged drains make it worse. We build up the low areas and clear or replace drains so water runs off.
Can a flat roof be coated instead of replaced?
Yes, if the membrane underneath is still sound. A reseal and silver coating can add years. See roof coating.
Do you do commercial flat roofs?
Yes, including TPO, PVC, SPF and EPDM. See commercial roofing.
