Excelsior Roofing & Commercial Roof Repair

Licensed, insured and working in Excelsior

Clearing the Excelsior gutters in late autumn prevents nearly all of the damage the first storm would otherwise cause. Sealant is the first casualty in Excelsior; it shrinks, cracks and pulls away from every penetration within a few seasons. As a rule, an Excelsior roof with working drainage outlasts an identical roof without it by years. Expansion and contraction loosens fixings on Excelsior roof coverings long before the material itself gives out.

Two visits a year keeps an Excelsior roof honest: clear the valleys and gutters before the rains, and check the flashings following the first heavy storm. Roof age across Excelsior clusters around the decades when the area filled in, which means whole streets reach the end of their covering within a few years of each other. San Francisco County is no different. As a rule, nearly all Excelsior roofs that let go early fail at a penetration someone could have resealed for a few hundred dollars. On most jobs, multi-unit buildings in Excelsior as a rule need a low-slope system and a maintenance plan rather than a one-off repair.

On most jobs, roof pitch across Excelsior varies enough that the right material on one street is the wrong one two blocks away. An Excelsior property often carries more than one roof type — a pitched main house in one material and a flatter garage or addition in another. Thermal cycling does the deterioration in Excelsior — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. Put simply, attic temperatures in Excelsior drive shingle service life as much as the weather above does, which is why ventilation counts more here than the brochure suggests. San Francisco County is no different.
