What flat roofing covers
Flat roofing covers repair and replacement of low-slope roofs on houses, additions, garages and porches. That includes leak repair at seams and flashing, patching blisters and punctures, and full replacement with a TPO membrane, EPDM rubber or modified bitumen.
Roofers Hotline books the inspection, and the written estimate lists what was found: the membrane condition, the number of layers, the decking underneath and the drainage. Those details decide whether a repair is enough or the roof needs to come off. A roof that is wet underneath rarely stays fixed with a surface patch alone, so the estimate should say what lies below the surface.
If you can see ponding water, cracked seams or a stain on the ceiling below, call and ask for the inspection.

What does a flat roof repair or replacement involve, and what will it cost before anyone starts? Roofers Hotline books the inspection and gives you a written estimate before any work starts, so you see the scope and the price on paper first. Flat roofs hold water longer than sloped ones, so a small seam failure or a soft spot can turn into a ceiling stain within a few storms. Typical 2026 ranges from published cost guides run from $6,800 to $23,800 for a TPO membrane roof, which is why a clear estimate matters. Call for flat roofing and ask for the written estimate.

When to call for flat roofing
Call when water stands on the roof for a day or more after rain, when the membrane has bubbles, splits or open seams, or when a ceiling below shows a brown stain. Call after a hard storm too, because wind can lift an edge and hail can puncture a membrane without any sign from inside the house.
The cost depends on the material, and published 2026 cost guides give typical ranges. A TPO membrane roof runs $6,800 to $23,800, or $400 to $1,400 per square. EPDM rubber runs $6,800 to $22,100, or $400 to $1,300 per square. Modified bitumen runs $6,800 to $15,300, or $400 to $900 per square. These are published figures from Fixr and This Old House, not a quote.
Your written estimate depends on pitch, layers and decking. Call to book the inspection and get the real number for your roof.
How flat roofing works with Roofers Hotline

After the inspection you get a written estimate before any work starts. It names the material, the area in squares, the condition of the decking and the repair or replacement it recommends. You can compare it with the typical ranges above and ask questions before you decide anything.

Questions
Flat roofing questions
How much does a flat roof cost?
Published 2026 cost guides give typical ranges: $6,800 to $23,800 for TPO membrane, $6,800 to $22,100 for EPDM rubber and $6,800 to $15,300 for modified bitumen. Your price depends on pitch, layers and decking. Call for the inspection and ask for the written estimate.
What is the cheapest flat roofing material?
By the published 2026 ranges, modified bitumen has the lowest top end at $15,300, or $400 to $900 per square. TPO and EPDM reach higher. The right choice also depends on your roof's condition, so ask for the written estimate to compare materials.
How do I know if my flat roof is leaking?
Look for ceiling stains, damp insulation, water that stays on the roof after rain, and bubbles or open seams in the membrane. A leak often shows up away from where water enters. Call and book the inspection to find the source.
Can a flat roof be repaired instead of replaced?
Often yes, when the damage is limited to a seam, a puncture or flashing and the decking underneath is dry. If the insulation or decking is wet, replacement may be the better fix. The written estimate states which one your roof needs.
Can I call about a flat roof after hours?
Yes. Calls are answered 24/7, so you can report a leak at night or during a storm. Describe what you see, and a callback books the inspection. The written estimate comes before any work starts. Call whenever water is getting in.
