How to hire a roofing contractor in Sunnyvale
Ask for proof of insurance and a local, physical address. Storm chasers leave town.
Get the manufacturer warranty and the workmanship warranty in writing, separately.
Make sure the quote includes tear-off, decking repairs, underlayment, flashing and disposal.
Never sign over an insurance check or an assignment of benefits before the work is done.
Roofing Contractor questions, answered
How long does a roof replacement take?
Most single-family roofs are replaced in one to three days, depending on size, pitch and material.
Can I put new shingles over old ones?
Some codes allow one overlay, but a full tear-off lets the crew inspect the decking and lasts longer. Most reputable roofers recommend tear-off.
How do I know if hail damaged my roof?
Look for dented gutters, vents and AC fins at ground level. If those show hits, have a roofer inspect the shingles before filing a claim.
