Shingle Roof Replacement in The Mesa

It is legal up to a limit and it is a bad idea here for a specific reason: you cannot fasten reliably through two layers into the deck, so the new covering has worse wind performance than the old one did. In a climate where wind is the main hazard, that is the wrong trade.

It can. The requirement is on the aged solar reflectance in the CRRC listing, and the darker end of most ranges is where it gets marginal. Pick the color you want, then check its listing rather than assuming.

Because the warranty was written for an average American climate and this is not one. Hesperia sees a daily swing that can run forty degrees between afternoon and dawn, all year. Asphalt expands and contracts through that cycle until the mat cannot recover, which is why you see curling and granule loss early here.

More than the brand of shingle. A four-nail minimum passes inspection anywhere in the state; six nails placed correctly in the nailing zone is what survives sustained High Desert wind. It adds very little to a quote, it is invisible once the roof is on, and it is the most common thing to be quietly left out.

Four documented exceptions: an addition under 300 square feet of roofing, an attic radiant barrier, R-20 or better attic insulation, or properly sealed ducts. Out here the insulation route is usually the better buy anyway -- it cuts the cooling load rather than reflecting a fraction of it, on a house that runs air conditioning five months a year.
