Larger-capacity gutter systems, scuppers and internal drainage — because on a commercial roof, drainage failure shows up as ponding water and a voided membrane warranty.
On a commercial roof, drainage is not cosmetic. Water that cannot leave stands on the membrane, and standing water is what ages membranes early and voids manufacturer warranties. Roof Experts services commercial gutter systems, scuppers and drains across DFW and our Texas, Colorado, Missouri and Oklahoma markets.
The 48-hour rule
Water that remains on a membrane more than 48 hours after rain counts as ponding. It accelerates aging, encourages biological growth, adds structural load, and voids some manufacturer warranties outright — which is the part that tends to get attention.
The good news is that ponding is usually a drainage problem rather than a roof problem, and drainage problems are comparatively cheap to solve. Re-pitching a drain or adding tapered insulation in the low area costs a fraction of a replacement.
Twice-yearly inspection plus a check after any significant storm is the cadence most manufacturer warranties require to stay in compliance. It is also what gives you documentation that matters when you sell the building or file a storm claim.
That documentation is worth more than it sounds. A basic maintenance routine dramatically extends roof life and protects the warranty — see our maintenance programs.
If water is coming in now
Active leaks over occupied or stocked space get a 24-hour response. We stop the water — tarping or temporary diversion as appropriate — and scope the permanent repair afterwards rather than rushing something that will not hold. See commercial roof repair for the rest of what we service.
Runs and downspouts sized for the actual roof area rather than what was there before.
Clogged, cracked or undersized outlets — the cause of most flat-roof backups.
Drain re-pitching or tapered insulation where water stands past 48 hours.
Perimeter details re-secured after wind events, where gutters meet the membrane.
Debris removal on systems that have not been serviced in several seasons.
New systems where the existing drainage was undersized from the start.
Certified inspector on-site, photo-documented findings, written report, no pressure and no hidden costs.
Small repair, big repair, or full replacement — we tell you which one this roof needs and why.

Because a flat roof has nowhere to shed water passively. Water standing more than 48 hours is ponding — it accelerates membrane aging, grows biological matter, and voids some manufacturer warranties outright. On a pitched residential roof the same failure is untidy; on a membrane it is expensive.
Usually not. The fix is normally re-pitching a drain or adding tapered insulation in the low area, which is far cheaper than replacement. We will show you the standing-water evidence and scope the drainage fix first.
It can, if the work touches the membrane and is done by someone not certified on that system. Tell us the manufacturer and the warranty term and we will scope it to stay inside them.
Twice a year at minimum, and after any significant storm. That cadence is also what most manufacturer warranties require in order to stay in compliance, and the documentation matters when you sell the building or file a claim.
Active leaks get a 24-hour response. We stop the water first — tarping or temporary diversion as appropriate — then scope the permanent repair rather than rushing a fix that will not hold.
Free inspection, honest scope, real warranty. Most service work scheduled within 24–48 hours.
