Flat Roof Repair & EPDM Rubber Roofing in Pittsburgh, PA

EPDM rubber roofing systems for flat and low-slope roofs: full installation, replacement, and flat roof repair.

Ireland Contracting repairs and installs flat and low-slope roofs across the Pittsburgh area: home additions, porches, garages, rowhouse rear roofs, dormers, and any roof section where the pitch is too low for shingles. We install complete Mule-Hide and Versico VersiGard EPDM rubber membrane systems, and we repair existing rubber roofs: open seams, pulled edges, failed flashing, blisters, and ponding. Same crews, same free evaluation, and a straight answer on whether your flat roof needs a repair or a new membrane.

EPDM is a synthetic rubber roofing membrane with more than 50 years of proven, watertight performance on low-slope roofs. Unlike a shingle roof made of thousands of individual pieces, EPDM covers the roof in large continuous sheets, engineered to resist UV, ozone, hail, moisture, and extreme temperature swings, and to stay flexible through freezing winters as the building naturally expands and contracts. A properly installed EPDM roof lasts 25 to 30 years in our climate.

Flat roof repair: rubber roofs rarely fail in the field of the sheet. They fail at the details. The seam tape lets go and a lap opens; the membrane shrinks over the years and pulls away from the edge metal or a wall; a pipe boot cracks; a dropped tool or a limb punctures it; water ponds in a low spot and eventually finds the one bad seam under it. All of those are repairs. We clean and re-seam with new tape and primer, re-flash the penetration or the wall, patch the puncture, and correct the drainage that caused the pond. When the membrane itself has gone brittle and chalky across the roof, we tell you that, because patching brittle rubber is throwing money at it.

Asphalt shingles are designed to shed water down a sloped roof. When the pitch is too low, water lingers and can work underneath the shingles, which is why we evaluate the roof pitch and application first instead of installing shingles everywhere. On a flat or low-slope section, a properly designed membrane system is the right tool for the job.

A quality rubber roof is more than the membrane. We install EPDM as a complete system, with careful attention to the roof deck, insulation where applicable, membrane attachment, seams, flashing, penetrations, edges, transitions, and drainage: the places where low-slope roofs actually fail. Where a roof has been ponding, we look at the drain, the scupper, or the gutter first, because a new membrane over the same low spot will pond the same way.

Why EPDM fits Western Pennsylvania roofs

Pittsburgh weather swings from summer thunderstorms to weeks below freezing, and low-slope roofs bear the brunt of it: standing snow load, ponding meltwater, and freeze-thaw cycling. EPDM is identified by its manufacturers as an ideal material for northern climates because it stays flexible in cold temperatures instead of becoming brittle, and its continuous sheets leave far fewer places for water to get in.

The region's housing stock makes flat roofs common. The rowhouses and duplexes of Bloomfield, Lawrenceville, the South Side, and Mt. Washington almost all have a flat rear roof over the kitchen; the older neighborhoods are full of flat-roofed detached garages; and the 1950s and 60s ranches and split-levels of the North Hills and South Hills carry low-pitched shed-roof additions and porch roofs. Many were shingled anyway at some point, or covered in a hardware-store roll roofing that has cracked, and those are the roofs that leak. Replacing them with a purpose-built membrane system solves the problem for good.

The other local problem is drainage. Pittsburgh's flat roofs drain to a single scupper or a short gutter run that fills with maple seeds and leaves, and once the water can't get off the roof, ponding does the rest. We check that first on every flat roof call.

Our rubber roofing process

  1. 1 Roof evaluation. We assess the pitch, existing materials, decking, drainage, and penetrations, and whether the existing membrane is repairable or due for replacement.
  2. 2 System design & estimate. For a repair, we scope the seams, flashing, and drainage fix; for a new roof, we spec the membrane, attachment method, insulation where applicable, and edge details. Either way you get a written, itemized estimate.
  3. 3 Tear-off & deck prep. On a replacement we remove the old roofing, inspect the deck, and replace any compromised decking before the new system goes down.
  4. 4 Membrane installation or repair. We install or repair the EPDM with careful attention to seams, flashing, penetrations, edges, and transitions, where low-slope roofs are most likely to fail.
  5. 5 Final inspection & cleanup. We verify the details, confirm the roof actually drains, and leave the site clean.

Rubber Roofing FAQs

How much does a rubber roof cost in Pittsburgh?

The cost depends on the roof's size, what has to be torn off, whether insulation is part of the system, and how many edges and penetrations need to be detailed. A seam or flashing repair on an otherwise sound membrane is a much smaller job than a new roof. We provide a free, itemized estimate for your specific roof.

Should I repair or replace my flat roof?

If the membrane is still flexible and the problem is a seam, an edge, a flashing, or a puncture, repair it. If the rubber has gone brittle and chalky, has multiple open seams, or has been patched repeatedly, a new membrane is the better value. We'll tell you which after the evaluation.

How long does an EPDM rubber roof last?

A properly installed EPDM roof typically lasts 25 to 30 years in Western Pennsylvania, and the seams and flashing are what usually need attention before the sheet itself does. Keeping the drains clear is the single biggest factor in reaching the full lifespan.

Why is water pooling on my flat roof?

Ponding means the water can't get off the roof, usually a clogged scupper or gutter, a sagging deck, or a low spot the original roof was never pitched to drain. Standing water shortens the life of any membrane and finds the weakest seam, so we fix the drainage as part of the repair, not just the leak.

What is EPDM rubber roofing?

EPDM is a high-performance synthetic rubber membrane installed in large continuous sheets on flat and low-slope roofs. It has been used successfully for more than 50 years and is known for flexibility, durability, and resistance to UV, ozone, hail, and temperature extremes.

Why can't I just put shingles on a flat roof?

Asphalt shingles shed water as it runs down a sloped roof. On a low pitch, water moves too slowly and can work underneath the shingles, which leads to leaks. A membrane system creates a continuous waterproof surface designed specifically for low-slope applications.

Which parts of a home get a rubber roof?

Flat roofs, low-slope additions, rowhouse and duplex rear roofs, porch and patio roofs, garage roofs, dormers with minimal pitch, and low-slope sections connecting different areas of a home.

How does an EPDM roof hold up to hail and cold?

EPDM's flexibility and strength give it excellent resistance to hail and impact damage, and it remains flexible even in freezing temperatures, which is one of the reasons its manufacturers recommend it for northern climates like ours.
