Asphalt Shingle: Costs, Lifespan and Alternatives

A full replacement in North Hollywood is permitted and inspected through LADBS, the Los Angeles Department of Building and Safety. Small repairs generally are not, but the layer count and assembly are checked on any permitted job.

In inland conditions, composition shingle runs roughly fifteen to twenty-five years, tile underlayment twenty to twenty-five, and coatings seven to fifteen depending on the system.

Two visits a year: clear valleys and gutters before the rains, then check flashings after the first real storm. In North Hollywood that matters most because asphalt dries out and sealant pulls back from penetrations years before the field wears through.

We start at the flashings, check the deck from inside the attic, and photograph every elevation. On a North Hollywood property we pay particular attention to dried-out underlayment and attic temperature.

One to three days on a typical North Hollywood property, depending on size, pitch and how much deck needs replacing. Nothing is left open overnight.

Check the licence, liability cover and workers' compensation, then ask any North Hollywood contractor what happens if the deck is worse than expected — and get that answer in writing before the covering comes off.

Yes. Low-slope sections on North Hollywood buildings need a membrane or coating system rather than shingle laid flatter than it is rated for, and they are quoted separately from the pitched roof.

North Hollywood sits in Los Angeles County and takes long dry heat, hard thermal cycling and rain that arrives in a few concentrated storms. In practice that means asphalt dries out and sealant pulls back from penetrations years before the field wears through.
