Roofing Contractor in Cotati, CA

Rea Roofing Inc. serves Cotati alongside the rest of the 101 corridor. The work here runs from older homes near the plaza with pitched, sometimes complicated roofs, to later houses on the outskirts with straightforward composition roofs due for their second or third covering.

The older housing stock around the plaza has been extended and altered a great deal over the decades, and that is where the roofing complexity lives. An addition put on in the 1970s meeting an original 1920s roof creates a transition, a new valley or a low-slope section, and those junctions are where water gets in. Reading a Cotati roof properly means working out its history before quoting it.

Because the town sits on the 101 corridor between Rohnert Park and Petaluma, it gets the same combination of steady winter rainfall and the wind that comes through the Petaluma Gap from the southwest. Wind-driven rain at wall flashings and rake edges is a recurring cause of storm-only leaks on these roofs.

Cotati's smaller lots and mature street trees also mean debris. Overhanging limbs drop directly into valleys and gutters, and on a small roof it does not take much to block a valley completely. Trimming back and keeping drainage clear does more for a Cotati roof than most of what people spend money on.
