Our Pittsburgh Flat Roof Repair — What's Included

Real Leak Diagnostics

In addition, we locate the actual source — not just the drip — using moisture surveys and seam-by-seam inspection on every visit.

All Flat-Roof Systems

As a result, tPO, EPDM, PVC, modified bitumen, and built-up patches installed with heat-weld or cold-adhesive per manufacturer spec.

Ponding Water Fixes

For example, we correct low spots with tapered insulation or drain adjustments so standing water stops shortening your roof's life.

Flashing & Penetration Reseal

In fact, perimeter flashings, curbs, drains, and vent boots resealed with compatible membrane and new termination bar.

Frequently Asked Questions

How do I know if my flat roof needs repair or replacement?
If the membrane is under 15 years old and failures are localized to seams, flashings, or a few penetrations, a targeted repair is almost always the right call. For example, beyond 15 years with widespread ponding, ridging, or blistering, we'll price both options so you can compare 10-year cost of ownership.
What flat roof systems do you work on?
TPO, EPDM (rubber), PVC, modified bitumen (torch-down or self-adhered), and built-up (BUR) tar-and-gravel roofs. In fact, we service mechanically fastened and fully adhered assemblies, and can identify unknown membranes during the inspection.
Can flat roofs be repaired in Pittsburgh winters?
Cold-adhesive and heat-weld repairs can be done below freezing, but seam adhesion is most reliable above 40°F. Similarly, for active winter leaks, we install a temporary weatherproof patch on the same visit and return for the permanent repair when conditions allow.
How long does a typical flat roof repair take?
Most single-point leak repairs are completed in one visit, usually under four hours. Because of this, multi-point or full flashing rebuilds typically finish in one day. What’s more, complex commercial jobs are staged so no section is left exposed overnight.
Do you offer a warranty on flat roof repairs?
Yes — every repair comes with a written workmanship warranty delivered with your final invoice. In particular, manufacturer material warranties transfer when we use approved products and installation methods, which we confirm before starting.

More Questions Homeowners Ask

What actually causes ponding water on flat roofs?
Deck deflection between joists, compressed or wet insulation, and clogged internal drains are the three most common causes. In addition, if water stands more than 48 hours after rain, the underlying cause needs correction — not a patch over the top.
Can you match my existing roof membrane?
Yes. As a result, we identify the exact membrane type, thickness, and manufacturer during inspection, then use compatible materials for the repair. For example, matching preserves any active manufacturer warranty and prevents the chemical incompatibilities that cause repeat failures.
Do I need to be home during the repair?
No — most flat roof repairs are exterior-only and don't require building access. In fact, we only need someone on-site if the leak requires interior inspection or if the roof is only reachable through an interior stairwell.
Do you handle commercial flat roofs?
Yes. Similarly, we work on both residential and commercial flat roofs across Pittsburgh — from garages and additions to warehouses, restaurants, and multi-tenant buildings. Because of this, after-hours work, tenant coordination, and permit-required jobs can be arranged.
What happens if the leak comes back after your repair?
If a covered repair fails within the warranty period, we return at no charge for materials or labor on that specific repair. What’s more, the workmanship warranty is written, not verbal, and is handed over with your invoice.
