As a Richmond commercial roof leak repair contractor, we trace each drip uphill from the ceiling stain to the seam, curb, or drain letting water in.
A Richmond commercial roof leak repair contractor first sorts a single entry point from a roof that leaks everywhere. These signs point one way or the other.
The inside of the building tells the roofer where to start. The featured clue is the one owners see first.
On a steel deck, water can run along the flutes for some distance before it drips through a joint. The stain marks where it came out, and the entry is often uphill toward a curb, a pipe, or an open lap.
Usually MeansThe trace starts at the stain and works uphill on the roof.
Rain blown from one side points to edge metal, coping, or counterflashing on that wall.
Water near a column or drain leader can come from the drain pipe under the deck.
A spongy feel on the roof means wet board that has to come out before patching.
A patch that keeps failing often sits over wet board or the wrong material.
Leak work comes down to four tools. Which ones a visit uses depends on how clear the water path is.
Each ceiling stain is marked on a plan, matched to a spot on the roof, and every seam, curb, and pipe uphill of it is checked for open laps, split flashing, and loose fasteners.
When visual checks come up empty, suspect spots are flooded with water one at a time, starting downhill. A drip inside while one spot runs pins down the entry.
Infrared scans at night after a sunny day show wet board releasing heat slowly. Capacitance meters map the same areas, and small test cores confirm the readings and are patched right away.
Once the entry is found, wet board is cut out, the failed seam, curb, or drain is repaired in matching material, and nearby details are checked for the same problem.
Finding the real entry point once costs less than chasing the same stain every few storms.
Repeat leaks usually mean the first repair treated the wrong spot. A full trace from the stain uphill finds the entry that was missed.
Leak tracing follows a fixed order, so nothing on the water path gets skipped.
The roofer starts inside at each stain, measures its position from walls or column lines, and checks the deck underside for runs of water along beams.
On the roof, the matching spot is found and every seam, curb, and penetration uphill of it is checked. Wind direction from your notes narrows which wall to start on.
Spots are water-tested one at a time from the downhill end, and moisture readings mark wet board around the entry so the patch goes over dry material.
Repairs go in at the source, then the same area is checked after the next rain. Photos and a marked plan go to you with the notes.
Once the entry point is found, the repair belongs to one of these jobs.
Openings at laps, curbs, or boots on a membrane roof are closed with flat roof repair in matching sheet.
Water getting in along screw rows or panel laps on steel buildings needs metal roof repair and a full fastener pass.
Sources around exhaust fans and process vents call for industrial roof repair with residue-resistant patches.
Answers on tracing leaks and stopping them.
Start at the interior stain, measure where it sits, and work uphill on the roof from that point. Mark the stain on a plan, check every seam, curb, and pipe uphill, look for open laps and split flashing, then water-test suspect spots one at a time from the downhill end.
TPO and PVC leak at cold welds, T-joints, and boots. EPDM leaks at seam tape edges and termination bar. Mod bit and built-up leak at blisters, laps, and pitch pans. Metal roofs leak at seam ends, closures, screws, and gutters. Skylights, RTU curbs, and parapets show up on every list.
Yes. A moisture survey with infrared, capacitance, or similar meters maps the areas holding water, and small test cores confirm what the meter shows. That matters because a patch over soaked board leaves water trapped under the membrane, so those boards come out first.
Protect people and contents first: move equipment, set out buckets, and rope off wet floors. Stay off the roof in storms. Then record each drip by column line or room number, the time it started, the wind direction, and photos of tiles and deck stains.
Usually the first repair treated the wrong spot or used material that cannot bond, like roof cement on a TPO seam. Wet board left under a patch, clogged drains, movement at joints, and a second leak nobody found also cause repeats. A full roof check breaks the cycle.
Send the address and where the water shows up inside, and we will trace it back to the spot on the roof.
Leave a name and number and a roofer will call you back about the leak or damage.
