Galvanized steel roof — San Mateo, CA

Last updated: September 24, 2026

What affects the price

When you start looking at a new roof, the final number depends on a few specific things. The total surface area is the biggest factor, but the steepness of your roof and how many stories your house has will change the labor intensity. We also look at the current material—stripping off old layers adds to the disposal fees. Choosing between asphalt shingles, metal, or tile shifts the budget significantly. Finally, if we find damaged decking underneath once the old roof is off, that needs replacement to ensure a solid structure. Exact pricing confirmed free on the call.

About this service

This is steel that has been coated in a protective layer of zinc to prevent rust and corrosion. It is an excellent choice for areas with high moisture or salt air, as the zinc acts as a shield against the elements. You should consider this material if you want a metal roof that maintains its structural integrity without needing constant painting or sealing. It is a cost-effective way to get the durability of metal while protecting your investment from environmental damage.
