What We Do | San Gabriel Roofing & Maintenance Roofing Services
We don't do a little of everything. We do roofing. That specialization is why we can offer manufacturer certifications and the best warranties available to San Gabriel homeowners.
Roof Replacement
After tear-off, we always check decking and replace what's needed. Soft spots mean moisture intrusion. The old roof was leaking longer than you realized. We use 7/16" or 15/32" CDX plywood depending on rafter spacing. New decking costs $75-$120 per sheet installed. We only replace what's actually damaged.

Roof Repair
Our roof repair process: inspect the issue, identify the root cause, quote the fix, do the work, warranty the repair. Simple. If the root cause is widespread (poor ventilation causes ice dams, for example), we'll recommend addressing that too. But the choice is always yours.

Storm Damage Repair
Wind speeds above 60 mph cause shingle tab lift and adhesive seal failure per ASTM D7158 testing protocols. Our San Gabriel inspectors check the entire windward exposure. Not just the obvious damage. Poor ventilation causes ice dams which cause water intrusion under the shingle field during freeze-thaw cycles. We document all contributing factors so your insurance claim covers root-cause repairs, not just surface patches.

New Roof Installation
We install new roofs on new homes, additions, detached garages, carports, and covered patios.

We help you choose based on your budget, aesthetic preference, and the specific demands of your San Gabriel climate.

Metal Roofing
Standing seam metal is the longest-lasting residential roofing material you can install. 40-60 year lifespan, virtually zero maintenance, and it sheds hail and debris better than any shingle. Our San Gabriel metal crews install residential and commercial standing seam, corrugated, and metal shingle profiles.

Shingle Roofing
Designer shingles like GAF Camelot II, Owens Corning Berkshire, and CertainTeed Grand Manor mimic premium materials. Slate, cedar shake, heavy wood. They cost 30-50% more than standard architectural shingles but the curb appeal is worth it for higher-end San Gabriel homes. Full manufacturer warranties included.

Flat Roofing
TPO single-ply membrane in 60-mil or 80-mil thickness, fully adhered or mechanically attached over minimum R-25 polyiso insulation. Hot-air welded seams tested with a probe at every joint. We install per NRCA and manufacturer specifications with tapered ISO insulation creating minimum 1/4" per foot positive drainage. Ponding water is the number one cause of flat roof failure in San Gabriel. Tapered insulation eliminates it. FM 4473 rated systems available for hail-prone areas. Fully warranted by Carlisle, Firestone, or GAF.

Commercial Roofing
For commercial kitchens and restaurants in San Gabriel, PVC membrane is the only option that resists animal fat and chemical exposure from rooftop grease exhaust. We install IB Roof Systems and Duro-Last PVC with heat-welded seams and custom accessories. Modified bitumen with SBS or APP polymer-modified asphalt for high-traffic commercial roofs. Two-ply systems with 20-year NDL (No Dollar Limit) warranties from Johns Manville or Firestone.

Gutter Installation
We custom-form seamless aluminum gutters on-site from a continuous coil of .027 gauge stock. No factory seams means no seam failures. We form them to the exact length your fascia requires. One piece, one gutter, no leaks.

Roof Inspection
Commercial and flat roof inspections include infrared moisture scanning with Flir E8 thermal cameras. Trapped moisture in the insulation layer shows as temperature differentials on the thermal image. No need to cut core samples everywhere. We identify wet zones, then core sample the suspect areas to confirm. This approach gives you a precise repair scope at a fraction of the cost of exploratory tear-offs.

Skylight Installation
Replacing an old leaking skylight is often cheaper than trying to repair it. New units from VELUX have Low-E laminated glass, argon fill, and No Leak guarantees when installed with the manufacturer's flashing system. Our San Gabriel crews replace skylights in a single day.
