Rainbow Roofing
A small Redwood City roofing contractor working the Peninsula's mid-century homes.
Acerca de
A leak that shows up with the first November rain is how most Redwood City homeowners meet their roofer, and a lot of the houses west of El Camino Real are now on their second or third roof. Rainbow Roofing is a small roofing contractor based on Valota Road, a residential street in west Redwood City near Woodside Road, with Joe De Lago as owner. Its LinkedIn company page and its site, redwoodcityroofer.com, place it in San Mateo County with a crew in the two-to-ten range; the site was offline when the chamber checked, so the service detail below describes the usual scope of a roofing contractor rather than the company's own list.
Scope of a roofing contractor
Contractors in this trade typically handle full tear-off and replacement, overlay where code allows, and repair of individual leaks, flashing, valleys and vent penetrations. On the Peninsula the common materials are composition shingles, with tile, standing-seam metal and low-slope torch-down or single-ply membranes on flat additions and garages.
Related work often includes gutter and downspout replacement, skylight installation and reflashing, attic ventilation, dry rot repair on fascia and sheathing, and inspections when a house is being sold. Solar-ready roofing and coordinating with a solar installer are increasingly part of the job in Redwood City.
Hiring a roofer well
Ask for the contractor's state licence number and look it up on the Contractors State License Board site, along with proof of workers' compensation and liability insurance. A written estimate should name the shingle brand and line, underlayment, flashing metal, the number of layers to be removed, disposal, and the labor and manufacturer warranty terms. Ask who will actually be on the roof, whether a permit will be pulled with the city, and how long the job will take; a straightforward replacement is often two to four days once materials arrive, and the dry season books up quickly.

Preguntas frecuentes
Típico de este tipo de negocioHow do I check a roofer's licence in California?
Ask for the state licence number and look it up on the Contractors State License Board website, which shows the classification, status, bond and workers' compensation coverage. A C-39 roofing classification is what to expect for roof work.
Does a re-roof in Redwood City need a permit?
Most full replacements do, and the city may require inspections at tear-off and completion. Ask who pulls the permit and whether the fee is included in the estimate, and keep the final sign-off with your house records.
Can a new roof go over the old one?
California code generally allows one overlay on a sound roof with only one existing layer, but weight, condition and the manufacturer's warranty terms matter. Ask the contractor to explain why they recommend tear-off or overlay for your house.
How long should a composition shingle roof last on the Peninsula?
Architectural shingles commonly carry manufacturer ratings of twenty-five to fifty years, but ventilation, tree cover and installation quality affect real life. Ask what the labor warranty covers and for how long.
