A Single Leaking Curb
With only one or two rooftop units, a cracked curb flashing is often the whole problem. Rebuilding it ends the leak over the office or shop below.
Commercial roof repair in Catalina, north of Oro Valley on Oracle Road, for small one-story shops, offices, and service buildings with simple roofs.


Commercial buildings along Oracle Road in Catalina are mostly one story, with a few thousand square feet of roof, one or two rooftop units, and access by ladder or a single hatch.
Small roofs mean small repair scopes. Most jobs here are a curb, a few seams, a drain, or a set of metal fasteners, done in one visit.
Small buildings share the same weak points as large ones, just fewer of them. These six come up most.
With only one or two rooftop units, a cracked curb flashing is often the whole problem. Rebuilding it ends the leak over the office or shop below.
Roof hatches on small buildings are the main access point. Worn gaskets and loose curb flashing leak right around the opening, often right over the back office or storage room.
Small roofs often drain to one outlet. When it clogs, the whole roof backs up behind the parapet. Clearing that one drain is the cheapest repair on the roof and often the most important.
Seams along the roof edge and at the parapet take the most sun and wind. They lift first on small flat roofs, and a short seam repair along one edge closes them before the monsoon arrives.
Metal shops and canopies lose screws and washers to heat cycling, the same as large buildings, just in fewer rows.
Wind across open lots along Oracle Road lifts loose edge metal and coping on small roofs, and rain follows the gap.

Most can. Small roofs with one or two problem areas are usually inspected and repaired in one trip, with materials matched on the first visit.
Hatch leaks come from worn lid gaskets or cracked curb flashing. New gaskets and rebuilt curb flashing stop them, and the hatch latch gets checked so the lid seals tight.
Twice a year, before and after monsoon season. On a roof with a single drain, clear it after any big storm too, since one clogged outlet can back water up across the whole roof.
Entry canopies and porches with metal roofs get screws, lap sealant, and trim repaired on the same visit as the main roof. They often drip right at the front door.
