Roofing systems built correctly
From Owens Corning shingles to Polyfresko torch down, every system is selected for the roof, installed with clean details, and backed by more than 25 years of hands-on work.

Full tear-off and re-roof with Owens Corning shingles, our go-to system for Los Angeles homes. We inspect and replace damaged decking, install new underlayment, flashing, and ridge ventilation, then finish with clean, straight courses and matching ridge caps.
Flat roofs need a system that handles standing water and California heat. We strip the old layers, rebuild the deck where needed, and torch down Polyfresko modified bitumen with sealed seams, proper drainage details, and reinforced edges.
A seamless elastomeric coating seals small cracks and reflects sunlight, dropping interior temperatures and adding years to an aging flat roof at a fraction of the cost of a full replacement.
Tile lasts for decades but the underlayment beneath it does not. We carefully remove and stack your tile, replace the underlayment and flashing, then re-lay the tile and swap out any broken pieces.
We find the actual source of the leak, not just the stain on your ceiling. Common fixes include flashing, valleys, pipe jacks, skylights, slipped shingles, and blistered flat-roof seams.
A yearly maintenance visit clears debris, reseals penetrations, checks flashing and drains, and gives you a written condition report so there are no surprises when the first storm arrives.
Complete roof care
We protect the full life of your roof—from the first inspection to urgent storm protection and routine maintenance.
When a roof fails mid-storm, we install heavy-duty tarps anchored properly so the wind does not take them. It buys you dry time until a permanent repair or insurance approval comes through.
Active leak, wind damage, or a tree on the roof? Call us and we will get out to stop the water, protect the interior, and give you a clear plan and price for the permanent fix.
Most roof leaks start with water that has nowhere to go. We clear gutters and downspouts, flush the lines, and check the fascia and drip edge for damage while we are up there.
We inspect the full roofing system, including shingles or membrane, flashing, penetrations, drainage, valleys, and visible decking concerns. You receive clear findings and practical next steps without pressure to replace a roof that can still be repaired.

A roof cricket is a small, raised structure built on the uphill side of a chimney or other roof penetration. It diverts rainwater around the obstruction instead of letting water collect behind it, helping prevent leaks and premature roof damage.
We prepare and seal the roof surface, reinforce vulnerable details, and apply a bright reflective coating that helps resist water and heat while extending the roof's service life.
Custom chimney roof work requires precise framing, flashing, sealing, and drainage. We build and repair the surrounding roof details so water moves away cleanly and every penetration is properly protected.
