Castro Roofing & Commercial Roof Repair

Licensed, insured and working in Castro

Multi-unit buildings in Castro usually call for a low-slope system and a maintenance plan rather than a one-off repair. Attic ventilation on a Castro property is not optional — trapped thermal load cooks the covering from underneath. Castro gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. It is the same story on most Castro streets. On most jobs, additions and conversions are common in Castro, and the joint between the original roof and the newer section is where most leaks begin.

Debris in Castro valleys holds what little moisture arrives against the covering, which is where rot generally starts. That is as true in Castro as anywhere in San Francisco County. Put simply, converted garages in Castro are a common source of leaks given that the roof was never upgraded with the conversion. In practice, second-storey additions in Castro create a junction between old and new roof that needs done right flashing rather than sealant. San Francisco County is no different. Dust and grit settle on Castro roofs through the dry months and wash into the drainage the first time it rains. That is as true in Castro as anywhere in San Francisco County.

As a rule, clearing the Castro gutters in late autumn prevents the majority of of the damage the first storm would otherwise cause. Older Castro buildings frequently sit on their second or third covering, and the layer count matters more than the age when planning the next one. Skylight seals on Castro roofs want checking annually, as they fail quietly and drip into the ceiling cavity. Trimming back branches over a Castro roof covering removes the debris that holds water against the covering and shortens its life.
