Flat · Metal · Leak · Industrial
We find where water gets into flat, metal, and industrial roofs on Tempe commercial buildings, then repair the seam, drain, curb, or fastener that let it in.
Each repair starts with what you can see from the roof or from the ceiling below, then fixes the part of the roof that actually failed.
Seams split by years of heat movement, blisters, and worn parapet flashing on TPO, EPDM, modified bitumen, and built-up gravel roofs, repaired with sheet that matches what is already there.
Backed-out screws, baked rubber washers, open side laps, and yellowed skylight panels on warehouse and shop roofs, where daily heat swings work the panels loose.
Ceiling stains rarely sit under the opening. Water runs along deck flutes and insulation first, so we trace it upslope and water-test one suspect area at a time.
Plant roofs carry exhaust fans, process vents, and dust collectors that leave residue on the membrane. Repairs get cleaned, checked against the discharge, and scheduled around production.
Most leaks start where the membrane stops, turns, or gets cut. These six details get checked first on every roof walk.
Years of heat movement pull seams apart. On TPO the crew probes each weld with a hand tool; on built-up roofs they look for open laps between plies.
Strainers and drain bowls fill with dust and debris, so water holds against the membrane and leaves a dark ponding ring that widens each season.
Base flashing at rooftop units cracks and pulls loose where service techs kneel, lean access panels, and set tools down.
Sealant at cap joints dries and cracks in the sun. Water then runs down behind the wall flashing and shows up inside along an exterior wall.
Filler inside pitch pans shrinks away from the metal, opening a ring around the pipe or conduit that drains straight into the deck.
Through-wall scuppers clog at the box and leak at the corners where edge metal meets the parapet, especially after a monsoon dust storm.
Every repair visit follows the same five steps, so you know what happens on the roof and what you get afterward.
We walk the roof and the space under it with a moisture meter, checking seams, laps, fasteners, flashings, drains, and any ceiling stain that points back to an entry point.
On The Roof
Suspect spots get marked with paint and photographed. When the source is unclear, one area at a time is water-tested until the drip inside shows up.
On The Roof
Before any cut goes into the membrane, you and the crew agree on sheeting over equipment and inventory, the path through the building, and working hours.
At The BuildingWelds go on TPO, seam tape and cover strips on EPDM, ply patches on built-up roofs, and new fasteners and butyl tape on metal panels.
On The RoofThe repaired area gets a hose test where the roof allows it. You receive marked-up photos of what was found, what was fixed, and what can wait.
PaperworkCall and tell us which room, how close it is to an exterior wall, and whether it started during rain or while the AC ran. Temporary leak control can come first.
A small opening caught early stays a small repair. Left open, the same spot soaks the layers under it with every storm.
The answer comes from what the roof shows. A moisture scan or core cut tells us how far wet insulation has spread before anyone prices a repair.
Each marker sits by direction from central Tempe. The areas differ in who issues permits and in the roofs that dominate them.
Mid-rise roofs reached through roof hatches, where the hatch curb itself is a common leak point.
Older Broadway shop roofs with skylights, smoke vents, and exhaust fans, each on its own curb.
Its own town, so a larger repair goes through Town Public Works before the work moves ahead.
A Phoenix village, where City of Phoenix rules decide when a repair turns into permitted re-roofing.
Retail and office centers with pitch pans, conduit runs, and sign wiring crowding the roof.
Tech and lab buildings where every cut in the membrane gets closed before the crew leaves.
Short answers on weather, cost, and roof types. Every question we get, with sources, is on the FAQ.
Heat, UV, and monsoon storms cause most of it. Months of direct sun dry out sealant and stiffen older membranes, and the swing from a hot afternoon to a cooler night flexes seams and fasteners until they open.
The National Weather Service in Phoenix sets monsoon season at June 15 through September 30. Its dust, downpours, and gusts lift loose edges and pack drains.
Yes. A walk after the storm catches lifted edge metal, torn membrane, and drains packed with dust before the next downpour finds them. Photos taken that week also help if you file an insurance claim.
Access and detail work explain most of the gap. A seam out in the open field takes far less labor than flashing tucked under a rooftop unit, and a three-story roof reached only by hatch costs more to stage than a one-story roof reached by ladder.
As soon as the roof is dry enough for a patch to bond. Temporary control can keep water out in the meantime, but wet insulation keeps spreading under a stopgap that never gets its permanent fix.
Offices, retail centers, warehouses, shops, labs, and plant buildings across Tempe and the six nearby areas. Flat, metal, and industrial roofs all start with the same roof walk and moisture check.
Often. The gravel gets scraped back, the plies are cut and patched in layers, and gravel goes back down so sun never reaches the patch. A core cut first shows whether the layers below are dry enough to repair.
Tell us where water shows up inside and what sits on the roof above it. We will set up a free roof inspection.
