Ralston Commercial Roof Repair Contractor

After an inspection shows what failed and how far water spread. A single seam or flashing fix is a small job, while replacing wet insulation and membrane is larger.

Roof system, access, and rooftop equipment add to it. You get a written scope with each line item before work starts, so nothing is a surprise on the invoice.

Ralston sits inside our regular repair area, so a call or message sets up the inspection. Have the address, the roof type if you know it, and a description of where water shows inside. Photos of the ceiling stains help us plan where to start before we arrive.

Yes, in nearly every case. Work happens on the roof, and ladders or lifts are placed away from docks and entrances. Inside, stock or equipment directly under the leak area gets moved or covered before any cutting starts above it, and the floor stays open around it.

Canopies get the same fastener and lap repairs as metal roofs, with extra attention to where the canopy ties into the building wall. That joint carries runoff from the main roof and is where most canopy leaks begin, so its flashing gets checked first.

Loose or failed patches come off so the new repair adheres to clean membrane. Well-adhered older patches can stay if they are dry and tight at the edges. Stacked layers of mastic hide leaks and get cut back to firm material before the new patch goes on.

Where stains appear, when the leak starts and stops relative to the rain, and any recent work by HVAC or electrical crews on the roof. Equipment work is a frequent cause of new punctures and open flashing, so that history points us to the right spot.

Twice a year suits most warehouse roofs: once in spring to catch winter damage at drains and flashing, and once in fall to clear debris before snow. Add a check after any hail storm or after contractors work on rooftop units, since both leave openings that lead to leaks.
