Four repair services for the commercial roofs we see most in the West Valley, each matched to the material and the part of the roof that failed.
Start with the roof material and where the water shows up. Each card marks the roof parts that service works on.
Membrane roofs over warehouses, offices, and retail centers. Open seams, blisters, dust-packed drains, and split curb flashing are the common calls, and each patch is matched to the existing sheet.
Flat roof repair in Glendale
Exposed-fastener and standing-seam roofs where screws back out, laps leak, and rust blooms around fastener heads. Cracked or yellowed skylight panels get swapped for matching profiles.
Commercial metal roof repair in Glendale
For the stain that keeps coming back. Tracing starts above the stain and moves upslope with a moisture meter and a controlled water test until the opening shows.
Commercial roof leak repair in Glendale
Large roofs with exhaust fans, process vents, and walkway routes. Oils and residue are cleaned off so patches stick, and grease-damaged membrane gets a more resistant material.
Industrial roof repair in GlendaleThe patch has to match the roof, or it lets go after a few hot summers. Here's what fails on each system and how it gets fixed.
| Roof System | What Fails | Repair Method |
|---|---|---|
| TPO | Heat-dried seams and punctures from foot traffic | Clean the membrane, then heat-weld a new TPO patch over the opening |
| EPDM | Seam tape lifting at laps and around curbs | Prime the surface and apply seam tape or a cover strip |
| Modified Bitumen Or Built-Up | Blisters, cracked plies, and worn surfacing | Cut out blisters, then torch or cold-apply new plies |
| Spray Foam | Bird peck holes and sun-browned foam | Grind out damaged foam, refill it, and recoat the patch |
| Metal Panels | Backed-out screws, open laps, and rust bloom | Oversized fasteners with new washers, resealed laps, and rust treated and primed |
| Skylights | Cracked or yellowed panels and open curb flashing | A panel of the matching profile and new curb flashing |
Standing water against a weak lap is often the next leak. Tell us where it pools and how long it stays after a storm.
Flat, metal, leak, or industrial, the visit follows one order so nothing gets patched before the cause is found.
A roof walk covers seams, laps, fasteners, curbs, drains, and flashings, and moisture readings near every leak area show where water has spread.
Interior stains are matched to spots on the roof above. A controlled water test on one section at a time confirms the opening before any patching.
Short-term steps keep more water out: clearing a backed-up scupper, sealing a split flashing, or covering a torn area so rain runs off.
The failed seam, fastener, curb, or flashing gets a permanent repair in the roof's own material, and wet insulation under it is cut out and replaced.
The repaired seams and flashings get a second look after the next storm, along with the ceiling below, so a missed opening gets caught early.
Answers on cost, materials, and which service fits.
Mostly the size of the damage and how hard it is to reach. The roof system and matching materials, the number of open seams or split flashings, and wet insulation that has to come out all add to it.
Roof height, hatch location, and any night or production-hour work count too. The inspection shows which apply.
Usually. A roof walk often turns up a split curb flashing, a packed drain, and an open seam on the same roof, and all three can be repaired in one visit.
Every patch is made from the system already on the roof: TPO welded to TPO, EPDM taped to EPDM, new plies on built-up, and fresh foam on foam. Mixed materials pull apart under daily heat cycles.
Start with commercial roof leak repair. The stain shows water is getting in, and tracing finds the seam, curb, or flashing letting it through. The repair then follows the flat, metal, or industrial method for that roof.
Quite different. Metal roofs leak at fasteners, panel laps, and openings, so repairs focus on oversized screws, resealed laps, and rust treatment, while flat roofs leak at seams, drains, and curbs.
Right after the first drip, while the wet area is still small. A short-term seal can hold until the permanent repair, and the cut-out stays smaller the sooner the opening is found.
Tell us the roof type and where it leaks, and we'll set up a free roof walk to confirm the repair.
Leave a name and number and we'll call you back about the leak or damage.
