Experienced roofing
from a local crew
Mario Contreras Roofing is based in Santa Rosa and serves homeowners and businesses throughout Sonoma County. With more than 20 years of roofing experience, we bring practical knowledge to repairs, reroofs, and new installations.
We believe you should understand what your roof needs before deciding what to do. That means taking a look, explaining the findings, and discussing the options. If a repair makes sense, that belongs in the conversation.
We’re licensed and insured, offer free estimates, and communicate in English and Spanish. Our work includes residential roofing, commercial roofing, gutters, and skylights.
