Water travels horizontally under the roof. Where it shows up on your ceiling is rarely where it enters. KPro traces leaks back to their actual source — drone aerial, attic inspection, water test.
Every leak detection 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 leak detection across every St. Louis suburb. Family-owned since 2020. 4.9 stars on 160+ verified reviews.
Most contractors guess. We have a process.
Stage 1 — Visual inspection. Drone aerial of the entire roof. Photos at every angle. Ground walk-around for siding, gutters, fascia.
Stage 2 — Attic inspection. Water-stains on rafters tell us where water is hitting. We follow the trail upward.
Stage 3 — Water test. If the source isn't obvious, we systematically run water on the roof to recreate the leak. We narrow the entry point to within inches.
Stage 4 — Repair or recommendation. Most leaks turn out to be flashings, vent boots, or seam issues — all repairable without replacing the roof.
Drone aerial + ground walk-around. Most leaks visible from above.
Water stains on rafters and insulation lead us to the entry point.
If still uncertain, we recreate the leak with controlled water flow.
Detection comes with itemized repair recommendation and estimate.

Water travels along framing and pools at low points. Sometimes the entry is 10–15 feet from where it shows up on the ceiling.
Rare but it happens with very intermittent leaks. We come back during the next rain and document live.
Most leaks identified in 30–60 minutes. Tricky ones may need a return visit during rain.
