Roof Installation in Santa Rosa, CA

Mario Contreras Roofing provides roof installation in Santa Rosa for new construction builds and full replacements on existing homes and commercial properties, backed by over 20 years serving Sonoma County. We install composition shingles, tile roofing, metal roofing, and flat roof systems throughout the area.

A roof installation done right starts well before the first shingle goes down. Whether you are in Fountaingrove, Rincon Valley, Bennett Valley, Skyhawk, or Larkfield-Wikiup, we inspect the deck, install proper underlayment, set up ventilation, and flash every penetration and edge before any roofing material is laid. That prep work is what separates a roof that holds up from one that causes problems in a few years.

  • 20+ Years installing roofs on homes and businesses throughout Santa Rosa and Sonoma County.
  • Lic. Fully licensed and insured in California on every job we take.
  • ES/EN Bilingual service in English and Spanish for Santa Rosa homeowners and contractors.
Why Choose Us

Why Santa Rosa Homeowners and Contractors Choose Mario Contreras Roofing

Santa Rosa gets hot, dry summers and wet winters — that seasonal swing puts real stress on roofing systems. Neighborhoods like Fountaingrove and the hillside areas also deal with wind exposure that accelerates wear on roofs that were not installed with care. We install every roof with local conditions in mind from the first layer up.

New Roof Installation

Roof Installation Serving Santa Rosa and Sonoma County

We install roofs throughout Santa Rosa — from homes in Larkfield-Wikiup and Fountaingrove to properties in Bennett Valley, Rincon Valley, Skyhawk, and the areas around downtown and Montgomery Village. For new construction, we coordinate with general contractors and framers to get the roof system installed on schedule without cutting corners on prep or flashing. For replacement projects, we do a full tear-off, inspect the deck for soft spots or rot, repair any damaged sheathing, and install the new system from the ground up.

We also handle related work like gutter installation and skylight installation as part of the same project so everything is done at once.
