Flat roof repair, handled fast.
Ponding water and failed seams are the two things that end a low-slope roof's life early, and we fix both across commercial properties throughout the DFW Metroplex.
Renovacore Builders LLC repairs flat and low-slope commercial roofs across the DFW Metroplex, from ponding water and seam failures to punctures from debris or foot traffic. Low-slope roofs don't have gravity working in their favor the way a pitched roof does, so any weak point in the membrane or the flashing holds water instead of shedding it. That's why a flat roof repair has to solve the water problem, not just patch the visible hole. We work on properties throughout Dallas, Fort Worth, and the surrounding area, and every repair starts with a free estimate.
Is water pooling on your building's roof or leaking through to the ceiling?
If you're seeing standing water that lingers for more than a day or two, or ceiling stains showing up inside, the roof has a drainage or membrane problem that needs attention. Ponding water is not just cosmetic. It adds constant weight and pressure on the membrane, works into any weak seam, and eventually finds a way to the decking underneath. A repair that just patches the visible spot without addressing why water is collecting there tends to fail again in the next heavy rain. The right fix looks at slope, drains, and seam condition together.
Warning signs to watch for
Standing water days after a rain
Water that should drain within a day or two but doesn't means the roof's slope or drains aren't doing their job. Left alone, it accelerates membrane breakdown right in that spot.
Blisters or bubbles in the membrane
Trapped moisture under the membrane pushes up as a blister. It usually means water already got in somewhere and has nowhere to escape.
Cracked or separated seams
Seams are where two sheets of membrane meet, and they're the first place a roof fails as the material ages. A cracked seam is a direct line for water into the building.
Punctures near rooftop equipment
Foot traffic around HVAC units, vents, and access points wears the membrane thin over time, and dropped tools or debris can punch straight through it.
What is causing the problem
Clogged or undersized roof drains
Debris buildup in drains, or drains that were never sized for the roof area, causes water to back up and pool instead of running off.
Membrane seams that have aged out
Old adhesive-set seams lose their bond over the years, and heat-welded seams can fail too if they weren't done right the first time.
Flashing pulled away from a wall or curb
Every transition point on a flat roof, walls, equipment curbs, parapet caps, needs flashing that stays tight to the membrane. Once it separates, water gets in fast.
Storm damage to the roof surface
Wind and debris can tear or puncture membrane that was otherwise sound. Documenting the damage matters if insurance is involved.
What to expect during the visit
We start by walking the full roof to find every spot where water is pooling or getting through, not just the area you noticed. Active leaks get sealed on the spot when it's safe to do so, to stop water from spreading inside while we work out the full picture. We check the drains, the slope, and every seam and flashing point in the affected area. Once we know what's causing it, we explain the repair plan and give you a clear estimate before any work begins, so there are no surprises on the invoice.

The cost of waiting
A ponding spot or a cracked seam doesn't fix itself, and on a flat roof it usually gets worse with every rain. Water that keeps finding the same weak point eventually saturates the insulation and decking below, turning a surface repair into a much bigger tear-out. Waiting through another storm season on a roof that's already showing seam or drainage problems is a bet that rarely pays off.
How do I know if my flat roof needs repair or full replacement?
It comes down to how much of the membrane and how many seams are affected. A repair makes sense when the problem is localized, like one bad seam or a single puncture, while widespread ponding, brittle membrane, or failing seams across the roof point toward replacement.
How long does flat roof repair take?
Most targeted repairs, like a seam reseal or a section patch, are completed in a single visit once the affected area is identified. Larger repair projects covering multiple problem spots take longer, and we'll give you a timeline with the estimate.
How much does flat roof repair cost?
Cost depends on how much roof area is affected, what's causing the problem, and how accessible the roof is. We inspect first and give you an itemized, no-obligation estimate rather than a number over the phone.
