What people ask before they hire a roofer

Architectural asphalt shingles typically last 25 to 30 years, metal 40 to 70, and flat membranes about 20 to 30. In the Valley, shade and humidity can shorten that.

It depends on the squares, pitch, material, layers and deck. The estimate page lists the fifteen things that move it.

Most houses take one to three days. Larger, steeper or metal roofs take longer, and winter can double it.

Almost always for a full replacement. We pull it, and the fee is a line on your estimate.

Age near the end of its range, curling or missing shingles, granules in the gutters, a sagging deck, stains or daylight in the attic, damaged flashing or moss.

Two parts: the manufacturer's material warranty and a workmanship warranty from us or the manufacturer. See the warranty page for the layers.

For many shingle makers, as long as the original owner owns a single-family house, for manufacturing defects only, and usually reduced after an initial period.

Deposit and any financing terms are written on your estimate before you sign. If financing is offered, the lender, rate and term are shown beside it.

Sometimes, but we tear off to the deck so we can see it. Code bars a second layer in some cases.

We tear off only what we can dry in that day and cover anything open.

Only contractors a shingle maker has approved can register its system warranties.

Move cars, take fragile things off walls, cover what is in the attic and keep children and pets away.
