Most gutter problems come from three things: wrong size, wrong pitch, or clogged debris. Grannis Roofing & Maintenance calculates gutter capacity based on your roof area, local rainfall intensity, and downspout placement. Properly sized and pitched gutters handle Grannis's worst rain without overflowing.
Hidden hangers screwed into rafter tails or fascia boards every 24 inches maximum. No spike-and-ferrule hardware that loosens over time. Proper pitch at one-quarter inch per 10 feet toward each downspout outlet. These details are what separate gutters that work from gutters that overflow.
Our Gutter Installation Process
Gutter Assessment
Before we form a single piece of gutter, we measure everything. Roof area, pitch factors, downspout runs, and fascia condition. Proper calculation prevents the overflow and backup problems that plague undersized systems.
On-Site Fabrication
Seamless means exactly that. Every section is one continuous piece formed on-site. Fewer joints means fewer potential leak points. Our portable equipment handles runs up to 100 feet in a single piece.
Expert Install
Hidden hangers every 24 inches, screwed into rafter tails through the fascia. Proper pitch to each downspout. Downspouts secured with brackets and directed away from your foundation with splash blocks or underground extensions.
Water Test & Walkthrough
After installation, we run water through the system to verify proper flow and check for leaks at every connection point. Old gutters removed and hauled off. Job site clean.
