San Gabriel Roofing & Maintenance installs seamless aluminum, copper, and steel gutters throughout San Gabriel. We custom-form every piece on-site with our portable gutter machine. One continuous piece, no joints, no leaks. Downspouts placed every 30-40 feet of gutter run for proper drainage.
We install 5-inch and 6-inch seamless K-style gutters. Standard homes get 5-inch. Larger roof areas, steeper pitches, or high-volume drainage zones get 6-inch with oversized 3x4-inch downspouts. Sizing matters. Undersized gutters overflow, undersized downspouts back up.
Our Gutter Installation Process
Gutter Assessment
We inspect your current gutters and fascia, measure your roof's effective drainage area, and calculate the gutter size and downspout placement needed to handle San Gabriel's rainfall. You get an honest recommendation, repair or replace.
Seamless Gutter Forming
Coil stock fed through our forming machine produces a seamless gutter to the exact measurement of your fascia. Custom miters, end caps, and outlet drops fabricated on the spot. Your color, your length, formed right in your driveway.
Precision Hanging
We hang with hidden hangers. No exposed hardware. Each hanger is screwed through the fascia into the rafter tail for maximum hold. Gutter pitch checked with a level at every section. Downspouts placed for optimal drainage away from the foundation.
Water Test & Walkthrough
Final walkthrough showing you the finished installation. We point out downspout discharge locations and gutter guard maintenance if applicable. All debris and old gutters removed from your property.
