Commercial roof repair services in Tucson for built-up, single-ply, and metal roofs, plus leak tracing and plant roofs that need work around production.
Start with the roof you have and what you see inside. Each service links to the details on that repair.
Low-slope roofs covered in built-up asphalt, modified bitumen, TPO, or PVC, where leaks start at seams, drains, curbs, and parapet flashing.
Exposed-fastener and standing seam panels on shops and warehouses, with loose screws, open laps, rust at cut edges, and cracked skylight panels.
Tracing an active leak back to where water enters, then a temporary seal if rain is near and the permanent repair once the cause is confirmed.
Large plant and distribution roofs with exhaust stacks, pipe supports, and heavy foot traffic, repaired in sections while the building keeps working.
Each roof system fails in its own way, so the repair material and method change with it.
| Roof System | Where It Usually Leaks | How We Repair It |
|---|---|---|
| Built-up (tar and gravel) | Blisters, cracked flashing at walls, split seams near drains | Cut and patch in layers with compatible asphalt materials, then reflash the wall |
| Modified bitumen | Lap seams, base flashing at curbs, alligatored cap sheet | Heat-welded or cold-applied patches of matching sheet over a cleaned surface |
| TPO or PVC single-ply | Seam welds, pipe boots, punctures from foot traffic | Probe the welds, then heat-weld patches of the same membrane |
| Exposed-fastener metal | Fastener holes, panel laps, rust at cut edges | Replace screws and washers, reseal laps, swap rusted panels by profile |
| Standing seam metal | Panel ends, ridge and eave closures, penetrations | Reseat closures, reflash penetrations, repair or replace seam sections |
Call and describe the roof and where the water shows up inside. The roof type and the stain location narrow it down fast.
Flat, metal, leak, or industrial, the work follows the same four steps.
A roofer walks every section, checks seams, drains, curbs, and flashings, and compares what is on the roof with the stains and drips reported inside.
Findings come back as marked roof photos and a short written scope, with each problem sorted into repair now, watch, or plan for later.
Repairs use the same material family as the roof, from heat-welded TPO patches to replacement screws and washers on metal panels.
After the repair, the area is cleaned, tested with water where it can be, and photographed so you have a record for the building file.
Size and access drive most of the cost. The roof system, how many leak points sit at seams, curbs, and drains, how much wet insulation turns up once the roof is opened, roof height and hatch location, and work around tenants or equipment shutdowns all change the number.
Yes. A single inspection covers the whole roof, so a curb leak, a clogged drain, and loose edge metal can go on one scope and be repaired in the same trip. Grouping repairs keeps lifts and staging to one setup.
We repair commercial roofs regardless of who installed them. Older patches get checked for what they were made of, because asphalt mastic over a TPO seam is a common reason a repair keeps failing.
It depends on the deck and insulation more than the age. A dry, solid roof with a few failed details repairs well. When core cuts show wet insulation across large areas, the money is better spent planning a replacement.
Skylight curbs, cracked domes, and hatch flashing are common repair items on Tucson roofs. Cracked or yellowed skylight panels on metal roofs get replaced with matching profiles, and curb flashing is rebuilt where sealant has failed.
Check the warranty terms before work starts. Some membrane warranties require a repair by an approved installer or a call to the manufacturer first, so send us the warranty paperwork and the work can be planned to keep it in force.
Tell us the roof type and what you see inside, and we will inspect the roof and lay out the repair.
Leave a name and number and we will call to talk through the leak or repair.
