  • Synthetic underlayment

  • Ridge ventilation

    Lets hot air escape along the peak of the roof instead of building up in the attic.

Questions about roof replacement

What’s included in a roof replacement?

A complete tear-off, new decking, synthetic underlayment, architectural shingles rated for California sun, and ridge ventilation. Everything included and anything excluded is listed in your written scope before work begins.

What if you find rot once the old roof is off?

It is the most common surprise in roofing, because soft decking and brittle underlayment stay hidden until the old covering comes off. Anything we find gets photographed and priced before we carry on, so nothing lands on your bill that you have not seen and agreed to. That is what the written scope is for: it sets out what is included, what is excluded, and how extra work is handled.

Do you replace the roof decking?

New decking is included in our roof replacements, along with synthetic underlayment and ridge ventilation.

Can you replace a roof that has solar panels on it?

The panels come off before the roof does and go back on afterwards, so the roofing work and the solar work have to be sequenced around each other. Tell us there are panels when you request an estimate and we will scope the roof around that. If you are about to install solar on an older roof, replacing the roof first is almost always cheaper than taking new panels back off a few years later.

What warranty do you offer?

Ten years on a new roof, which covers a full replacement and a new installation alike. One year on a repair.
