Flat Roof Issues We Solve

Common flat roof problems we diagnose and fix every day.

Ponding Water

Water that remains on the roof 48+ hours after rain. Accelerates membrane degradation.

Solution: Tapered insulation, drainage improvements, or coating systems

Membrane Punctures and Tears

Foot traffic, fallen debris, HVAC service, or animal damage can puncture flat roof membranes.

Solution: Patch repair or section replacement

Seam Separation

Seams between membrane sections can separate over time due to thermal movement or improper installation.

Solution: Seam re-welding or re-adhesion

Flashing and Edge Failure

Edges, penetrations, and transitions are common failure points. Metal flashing corrodes, membrane terminations fail.

Solution: Flashing replacement and edge repair

Blistering and Bubbles

Air or moisture trapped beneath the membrane causes bubbles that weaken the roof.

Solution: Blister repair or membrane replacement

UV and Weather Degradation

California sun breaks down roofing materials over time. Membrane becomes brittle, cracks.

Solution: Coating application or replacement

Factor Coating Replacement
Existing Membrane Mostly sound, minor issues Failed, severe damage
Insulation Dry and functional Wet or compressed
Ponding Water Minor or none Severe, structural fix needed
Cost 30% to 50% of replacement Full investment
Disruption Minimal, 1 to 2 days More involved, 3 to 7 days
Life Extension 10 to 15 years 20 to 30 years
We inspect your roof and give you an honest assessment. If coating can extend your roof's life economically, we will tell you. If replacement is the better investment, we will explain why.

What Our Flat Roof Customers Say

★★★★★

"Our mid-century modern home has a large flat roof that had been patched multiple times. Infinite Roofing replaced it with TPO and solved the ponding water issues with tapered insulation. No more leaks, and the white roof keeps our cooling costs down."

Richard and Ana M.
Fresno, CA — TPO Replacement
★★★★★

"The flat roof on our garage addition was failing. Infinite Roofing did just the flat section with modified bitumen and it matches perfectly with the rest of the house aesthetically."

Thomas W.
Modesto, CA — Modified Bitumen
★★★★★

"I manage a small office building and was dreading the cost of a full roof replacement. Infinite Roofing recommended a silicone coating instead. Saved us about 60% versus replacement, and they gave us a 15-year warranty."

Karen S., Property Manager
Hayward, CA — Silicone Coating

Flat Roof FAQs

TPO and EPDM typically last 20 to 30 years, modified bitumen 15 to 20 years. Coatings can add 10 to 15 years to an existing roof.

Flat roofs are actually slightly sloped, but over time the deck can sag, drains can clog, or the original slope was insufficient. A free inspection will identify the specific cause.

Both are excellent. TPO is more energy-efficient (white, reflective). EPDM is extremely durable and handles temperature extremes well. We recommend the right system based on your specific property and goals.

Occasionally, yes, but frequent foot traffic can damage membranes. Walk pads or pavers can protect the membrane if regular access is needed for HVAC service or rooftop equipment.

Typically $6 to $15 per square foot. For a 1,500 sq ft flat roof, expect $9,000 to $22,500. We provide free detailed estimates with no obligation.
