Zenia Roofing & Maintenance has replaced 244+ roofs across Zenia and Rancho Santa Margarita, Sausalito, Topanga, Woodland Hills, Big Oak Flat. Every replacement starts with a full tear-off and decking inspection. We find the damage the old roof was hiding, fix it, and build a new system designed for CA weather conditions.
We carry certifications from GAF, Owens Corning, and CertainTeed, the three largest shingle manufacturers in the country. Our Zenia crews are factory-trained and your roof qualifies for the best warranties available, including GAF Golden Pledge with 25-year workmanship plus 50-year materials.
Our Roof Replacement Process
Free Roof Inspection
Our Zenia inspector examines every component: shingles, flashing, pipe boots, ridge vent, soffit intake, decking condition from the attic side. We share photos on the spot and give you an honest assessment.
Your Detailed Proposal
You receive a written proposal with material specs, labor breakdown, timeline, and total cost. We price by the square and itemize everything. Compare apples to apples with any other quote.
Installation Day
Our crews average 8+ years experience each. Tear-off, decking inspection, ice and water shield, underlayment, drip edge, starter strip, field shingles, hip and ridge caps, and ridge vent, installed in the correct sequence per manufacturer requirements.
Final Walkthrough
Our project manager inspects the finished roof against the manufacturer checklist. You get a written workmanship warranty from Zenia Roofing & Maintenance plus the manufacturer warranty registered directly with GAF, Owens Corning, or CertainTeed.
