When patching isn't enough, KPro replaces flat roofs end to end — tear-off, deck inspection, insulation, membrane install, and full warranty.
Every flat roof replacement project KPro takes on starts with a free 24-hour drone inspection. We document everything before we touch a single shingle, fastener, or membrane — and you get those photos and the written assessment whether you proceed or not.
Our St. Louis customers have been telling us the same thing for 6 years strong: the difference is in the details. Three magnet sweeps for nails. Final drone inspection before sign-off. Two rounds of rain test for any roofing work. Owner on-site for every insurance adjuster meeting.
From Manchester to Chesterfield, Wildwood to Ballwin, Kirkwood to Town & Country — KPro has installed, repaired, and maintained flat roof replacement across every St. Louis suburb. Family-owned since 2020. 4.9 stars on 160+ verified reviews.
Most flat commercial roofs in St. Louis last 20–30 years. After that, repair becomes patch-and-pray. Replacement is the smart call when you see these signs.
Multiple recurring leaks. If you've patched the same area twice and it's still leaking, the membrane is failing.
Wet insulation. A core sample shows saturated insulation. Once it's wet, energy loss skyrockets and the structure rots underneath.
Major ponding. Water sitting more than 48 hours after rain. Drains aren't doing their job and the roof structure is at risk.
Seam failures across the building. EPDM seams letting go in multiple spots is a system-level failure.
On-site within 24 hours. Drone aerial photos, ground walkthrough, written assessment. Free even if you don't proceed.
Itemized: materials, labor, warranty terms. No surprises, no hidden fees.
Materials delivered the morning of. Crew on-site at 7am. Most residential jobs finish in one day.
Three magnet sweeps for nails, final inspection together, you sign off. Manufacturer + KPro labor warranty on file.
