Nogales commercial roof repair for flat, metal, and industrial roofs: we trace the leak, fix the seam, drain, curb, or fastener that let water in, and keep your building running.
Each repair starts with the detail that failed. The numbered points on each roof plan show where we look first on that kind of roof.
Built-up, modified bitumen, TPO, and EPDM roofs on port-area warehouses and downtown buildings. Seams, drains, scuppers, and curb flashing get repaired with material that matches the sheet already on the roof.
Flat roof repair in Nogales
Pre-engineered steel buildings, shops, and farm structures where daily heat and cold work screws loose. Repairs replace fasteners with oversized screws, reseal laps, and treat rust before it eats through.
Metal roof repair in Nogales
For the stain that keeps coming back. We work upslope from the ceiling tile with moisture readings, stop the water with a temporary seal when needed, and make the permanent repair once the roof dries.
Roof leak repair in Nogales
Plants, packing houses, and cold storage near the Mariposa Port, where roofs carry condensers, exhaust fans, and process vents. Work zones and heat work are set with your facility team before anything opens.
Industrial roof repair in NogalesMost repair calls start inside the building. Here is how the common symptoms trace back to a roof detail, and what the repair involves.
Water entering at a seam or curb corner, then running along deck flutes before it drips.
Trace upslope from the stain, confirm the wet path with a meter, and reseal the opening at its source.
A loose clamping ring or a strainer packed with dust and monsoon debris backing water up.
Clear the bowl, reset or replace the clamping ring, and flash the membrane back into the drain.
Split corner flashing at the HVAC curb, often opened by service traffic and daily heat swings.
Cut out the failed corners and install new curb flashing tied into sound membrane on all four sides.
Screws backed out of the panel ribs with cracked rubber washers letting water in at each hole.
Replace them with oversized screws and new washers, then treat rust at the heads and laps.
Cracked coping or loose counterflashing at the parapet, so water gets behind the base flashing.
Reset the coping joints, fasten the counterflashing, and repair the base flashing below it.
Edge metal peeled back by wind, torn membrane at a corner, or hail cracks in a skylight panel.
Photograph the damage first, cover the opening, and rebuild the edge or panel once the roof dries.
Nogales roofs cover very different operations. A repair made early protects whatever sits under the roof, from produce on racks to a downtown storefront.
A drip at a condenser curb over a cold room can freeze on racks or product. Sealing that curb early keeps the cooler running and the floor clear of ice.
Once water soaks the insulation under the membrane, a small repair turns into replacement planning. Fixing the opened seam now keeps the wet area to one bay.
Rust that starts at a screw head spreads along the lap. Treating it while the steel is still solid saves the panel from replacement.
Planned repair work happens on the roof surface, so docks, sales floors, and offices below stay open while we work.
Call and tell us where the water is showing up. A temporary seal can keep it out of the building until the roof is dry enough for the permanent repair.
It comes down to what sits under the membrane and how much of the roof is failing. The core cut and moisture readings settle it.
Repair work happens in two places at once: on the roof, and in the building below it. Each step sits in the lane where it happens.
We walk the roof and the interior together, check seams, curbs, drains, and fasteners, and take moisture readings over any stain.
Roof work zones, ladder spots, and heat work get set with your facility manager so shipping, receiving, and cold rooms keep running.
An open seam or split flashing gets compatible tape or mastic, and a packed drain gets cleared, so water stops entering now.
Once the roof is dry and clean, we rebuild the failed detail with material matched to your membrane or metal panel.
After the next rain we look at the ceiling tile and deck again and hand you dated photos of the work.
We repair commercial roofs in Nogales and five nearby communities. Four sit north along I-19; Patagonia sits northeast on SR 82.
Cold storage roofs crowded with condenser curbs, where a drip over a cold room is the call we get most.
Permits: Santa Cruz CountyMetal farm buildings with exposed screws, dried lap sealant, and rust at the cut edges.
Permits: Santa Cruz CountyShop buildings with parapets and through-wall scuppers that pack with leaves and dust.
Permits: Santa Cruz County + historic zone reviewMain street storefronts that share walls, so a leak often starts where one roof meets the next building.
Permits: Town of PatagoniaRoadside buildings on open ground where monsoon wind peels edge metal first.
Permits: Santa Cruz or Pima CountyHeat by day and cold at night do most of the damage. Nogales sees roughly 100 nights at or below freezing and more than 100 days at 90°F or higher, according to the Arizona State Climate Office. That swing stretches seams, cracks flashing sealant, and loosens metal screws until a lap opens.
Plan two roof walks a year: late spring before the monsoon and fall before hard freezes, plus one after any severe storm. Each visit clears drains and scuppers, probes laps, checks curb flashing, and snugs loose metal fasteners. Ponding rings get mapped so drainage problems are caught early.
Age alone does not decide it. The condition of the membrane or panels around the leak does. A 20-year-old roof with dry insulation and flexible membrane repairs well; a younger roof with wet board across many bays is a replacement conversation.
Yes. We repair built-up, modified bitumen, TPO, and EPDM flat roofs, and exposed-fastener and standing-seam metal roofs. Each repair uses material that bonds to the existing sheet or panel, so the patch moves with the roof around it.
Most repair work happens on the roof surface, so the building below keeps operating. Heat or flame work near exhaust stacks, access through the building, and ladder locations get agreed with your facility manager before work starts.
Note where stains or drips appear and when they started, and pull any old repair invoices. Photos of the ceiling after rain help us trace the water. Roof access, such as a hatch key or ladder location, saves time on the day.
Rio Rico, Tumacacori-Carmen, Tubac, and Amado along I-19, and Patagonia on SR 82. Permits for larger work run through the City of Nogales, the Town of Patagonia, Santa Cruz County, or Pima County for some Amado parcels.
Tell us where the water shows up. We inspect the roof and explain what needs repair now and what can wait.
Leave a name and number and we will call you back about the leak, the seam, or the panel that has you worried.
