We find where water gets into commercial roofs in Tucson and repair it: split seams, clogged drains, loose metal fasteners, and failed flashing.
Each service follows the water from the spot where it gets in to the stain your tenants see, so the repair lands on the cause.
Built-up, modified bitumen, TPO, and PVC roofs on low-slope buildings. Repairs start at seams, drains, curbs, and parapet edges, where sun and standing water break a flat roof down first.
How The Water Travels
Exposed-fastener and standing seam panel roofs on shops, warehouses, and plants. Afternoon heat moves the panels, and over the years that movement loosens screws and opens laps.
How The Water Travels
Active leaks on any commercial roof when the source is unknown. We work upslope from the stain, water-test sections, and read moisture before cutting anything open.
How The Water Travels
Plant, warehouse, and distribution roofs with exhaust fans, pipe racks, and production underneath. Work is sectioned and scheduled around shifts, hot-work rules, and fan shutdowns.
How The Water Travels
Sun, heat swings, and monsoon storms work on the same few details. These six cause most of the repair calls.
Years of ultraviolet exposure dry the edges of built-up and single-ply seams until they lift. Water gets under the lap in the first hard monsoon rain and runs along the deck.
Dust, leaves, and gravel collect at drain bowls and canales. Water backs up behind the parapet, and once it rises above a flashing or seam, it finds a way in.
Panels expand in afternoon heat and contract overnight. That cycle works screws loose and cracks neoprene washers, leaving a small hole wherever a fastener backed out.
Curbs under air handlers and exhaust fans carry the most flashing per square foot of roof. Cracked sealant and torn base flashing at a curb send water straight into the ceiling below.
Cracked stucco, loose coping, and failed wall flashing let water into the top of the parapet. It travels down inside the wall and shows up as a stain along the exterior wall.
Older built-up roofs develop blisters and a cracked, alligator-like surface as the asphalt ages. Small areas get cut out and repaired; widespread cracking points toward a replacement plan.
Most roofs we inspect in Tucson can be repaired. These signs help sort a repair from a roof that needs a replacement plan.
Call with the building address and where the drip shows up inside. A stain near a wall or under a rooftop unit tells us where to start.
Four steps on every roof we repair, with photos and notes you can keep.
We walk the field, edges, drains, and every curb, match ceiling stains to entry points above, and take moisture readings where water has spread into the insulation.
You get photos of each problem area marked on a roof sketch, with a plain note on what needs repair now and what can wait until fall.
Crews reseal or replace the failed seam, flashing, fastener, or panel with material that matches the roof, and clear drains that held water against it.
Repaired sections get a water test where practical, then a final walk with photos so your records show what changed on the roof.
A fix that holds at the seam, drain, or curb matters to more than the person paying for it.
We repair commercial roofs across the basin, from Catalina in the north to Green Valley in the south.
Short answers to common calls. More are on the commercial roof repair FAQ.
Repair it while most of the roof is dry and the deck is solid. Replacement moves up when core cuts find wet insulation across large areas, the deck is rusted or sagging, or new leaks appear after every fix. A brittle membrane, or a roof near the end of its life, rarely justifies a large repair bill.
Soon, because water that sits in insulation spreads and adds to the repair. Call with the address and where the drip shows up, and we will set an inspection. If rain is coming, a temporary seal at the source limits interior damage until the permanent repair is done.
Yes, between storms, once the roof is dry enough to walk and work on safely. The National Weather Service in Tucson treats June 15 through September 30 as monsoon season, so late spring is the best time to clear drains and close open seams.
In most cases, yes. Built-up and modified roofs get compatible asphalt-based patches, TPO and PVC get heat-welded patches of the same membrane, and metal panels are replaced with the same profile and gauge when it is still made. Mismatched material is a common reason old patches fail at the edges.
Inspections cover the field of the roof, seams, drains, scuppers, canales, curbs, flashings, parapets, and skylights, plus any ceiling stains inside. Moisture readings are taken where stains point to wet insulation. You get photos and a plain explanation of what needs repair now and what can wait.
Most repairs happen above occupied space. Roof cuts and heat-welding are planned with the building contact, and rooftop units are shut down only when a curb repair needs it. Ladders, lifts, and material staging stay clear of entrances and loading areas.
