AfterFlat Roof Repair Done Once, and Done Right
A flat roof does not forgive shortcuts. Water has nowhere to run, so a small split in the membrane or a lifted seam can turn into a stained ceiling within a single storm. Tilehurst Roofing has handled flat roof repair across the United States since 2000, and we built our name on a simple promise: you get a written price before any work starts, and you know exactly who is on your roof. If you have a leak, a soft spot, or water that sits for days after rain, call us at (945) 303-9821. We cover homes, townhouses, porches, additions, and small commercial buildings with the same careful approach.
Most flat roofs are not truly flat. They carry a slight slope so water drains toward a scupper, a gutter, or an interior drain. When that slope settles, when a drain clogs, or when the membrane ages out, water starts to pool. Standing water speeds up every kind of damage, from UV breakdown to seam failure. Our crews find where the water is actually getting in, fix that spot, and then look at why it happened so the repair holds. You can see the rest of our work on our home page.
What Our Flat Roof Repair Service Includes
A good flat roof repair starts with a full look at the roof, not just the spot where you see the stain. Water travels along the deck and insulation before it shows up inside, so the leak you notice is rarely where the damage begins. Our team follows the same steps on every job.
Leak Tracing
We walk the whole surface, check penetrations, drains, and edges, and probe wet areas to find the real entry point. Guessing at a leak and patching the wrong spot is the most common reason a repair fails within a season.
Seam and Membrane Repair
Open seams, blisters, splits, and punctures get cleaned, dried, and sealed or patched with materials that match your system, whether that is TPO, EPDM, PVC, modified bitumen, or built-up roofing.
Flashing and Edge Work
Parapet walls, curbs, vents, and roof edges are where flat roofs leak most. We replace tired flashing and re-seal terminations instead of smearing sealant over a failing joint.
Drain and Ponding Fixes
We clear and repair drains and scuppers, and where water sits we correct the low spot with tapered material so it runs off instead of soaking in.

Flat Roof Materials We Repair
Every flat roofing material fails in its own way, so the repair has to match the system. Using the wrong patch on the wrong membrane is how a ten-minute fix becomes a recurring leak.
TPO and PVC are white single-ply membranes with heat-welded seams. When a seam opens or a puncture appears, we clean the area and weld a new patch rather than gluing something on top. EPDM is the black rubber membrane common on homes and small buildings. It takes adhesive-based patches and seam tape, and it needs a clean, dry surface to bond. Modified bitumen and built-up roofing use layers of asphalt and reinforcing fabric, and they usually fail at laps, flashing, and around penetrations. For a roof that is past the point of patching, our roof installation team can walk you through a full replacement with the same written pricing.
Signs Your Flat Roof Needs Repair
Flat roofs hide problems well. Catching them early keeps a small repair from turning into a deck replacement.
- Standing Water After Rain: Water that stays more than 48 hours means the roof is not draining. Ponding adds weight, breaks down the membrane, and finds every weak seam.
- Ceiling Stains or Peeling Paint: Brown rings, bubbling paint, or damp drywall under the roof point to an active leak. By the time you see it, the insulation above is often wet.
- Blisters and Bubbles: Raised pockets in the surface are trapped moisture or air. They can split open under foot traffic or heat and let water straight in.
- Cracked or Open Seams: Seams that have lifted, shrunk, or pulled apart are a direct path for water, especially along walls and around vents.
- Exposed Fabric or Granule Loss: If you can see the reinforcing mesh or bare patches where the surface has worn away, the membrane has lost its protective layer.
- A Soft or Spongy Feel: A roof that gives underfoot has wet insulation or a damaged deck below. This needs attention quickly.
Safety Warning: Flat roofs look easy to walk on, but wet membranes are slippery and weak decking can give way. Please do not climb up to inspect it yourself. If you want a trained set of eyes, our roof inspection service covers the whole roof and gives you a written report.
Our Flat Roof Repair Process, Step by Step
We keep the process simple and consistent so you always know what comes next. Under the guidance of Greg Holloway, our crews follow these steps.
- 1
Inspection and Leak Tracing: We check the surface, seams, drains, flashing, and edges. If needed we use moisture checks to see how far the water has spread under the membrane.
- 2
Written Price and Options: You get a line-item price in writing, with a repair option and, if the roof is near the end of its life, a straight comparison against replacement.
- 3
Prep and Dry-Out: We remove wet or damaged material, clean the surface, and let the area dry. Sealing over moisture is a fast way to trap the problem inside the roof.
- 4
Repair and Re-Seal: We install the patch, replace flashing, fix the drain or low spot, and seal every edge to match your roof system.
- 5
Cleanup and Walkthrough: We clear all debris, check that water moves toward the drains, and walk the finished work with you before we leave.
Repair or Replace a Flat Roof
We would rather tell you the truth than sell you a roof you do not need. A repair makes sense when the damage is local, the membrane still has life left, and the insulation underneath is dry. Replacement makes sense when leaks keep returning in different places, when more than a fraction of the insulation is wet, or when the roof has passed its normal lifespan. Single-ply and modified bitumen roofs commonly last somewhere between fifteen and thirty years depending on material and care. If your roof is in that window and repairs are stacking up, the numbers often favor replacing it. We lay out both choices in writing and let you decide.
How Much Does Flat Roof Repair Cost?
A small flat roof repair, such as a single seam, a puncture, or a flashing fix, often runs from a few hundred dollars up to around $1,500. Larger jobs that involve drain work, wet insulation, or several repair areas can reach $3,000 to $6,000 or more. Because every roof is different, the only honest number is one based on your actual roof. Our quotes are fixed, line-item estimates that tell you what you are paying for before we start.
Several things move the price: the roofing material, how large the damaged area is, how accessible the roof is, and whether the insulation or deck below has water damage. If we open the roof and find hidden damage, we show you the problem and give you a written change order for approval before we go further. If a different kind of damage is behind your leak, such as a recent storm, our storm damage roof repair page explains how we handle that work.

Frequently Asked Questions About Flat Roof Repair
Most spot repairs take a few hours to a single day. Larger jobs with drain work or wet insulation can take two to three days. We give you a specific timeline when we price the job, so you know when our crew will be at your property.
Yes, in many cases. If the damage is limited to a seam, a flashing detail, or a small area and the insulation below is dry, a targeted repair is the right call. If the roof is old and leaking in several places, we will tell you honestly when replacement is the better value.
Small repairs often cost from a few hundred dollars to about $1,500, while larger repairs can run several thousand. The material, the size of the damage, and any wet insulation all affect the price. Call (945) 303-9821 for an exact quote. Estimates are free.
A repeat leak usually means the first repair treated the symptom. The water may be entering somewhere else and traveling to that spot, or the flashing and drainage causing it were never fixed. We trace the source and correct the cause so the repair holds.
If you have an active leak, call (945) 303-9821 and speak with a live person. We can often put a temporary fix in place to stop water from damaging your home while we prepare the written price for a permanent repair.
Every repair we perform is backed by our 365-Day Done Right Promise. If the work we did fails within one year of completion, we come back and fix it at no charge to you. We put that in writing before we leave the job.
