As a rule, annual inspection on a Portola property typically adds two to three years to the back end of a roof's service life. Drainage is the cheapest maintenance on any Portola building — blocked outlets cause more damage here than the storms themselves. Skylight seals on Portola roofs want checking annually, as they fail quietly and drip into the ceiling cavity.

Two warranties apply on Portola work: the manufacturer's on the material and the installer's on the workmanship. Ask for both.
