First: Should you DIY this?
We're professional gutter installers, so it might sound self-serving to say this — but the honest answer is: for seamless gutters, no, you can't DIY. Seamless gutters are formed on-site from a continuous coil of aluminum using a $5,000+ portable gutter machine. You can't buy a seamless gutter at Home Depot.
For sectional gutters (the 10-foot pieces from the hardware store), DIY is possible if you have roof access, basic tools, and patience for the joints. But you'll end up with visible splice pieces every 10 feet and a higher chance of leaks over time.
That said — here's how professional gutter installation works so you know what to expect when you hire someone, or if you really do want to tackle a sectional install yourself.
Tools and materials you'll need
For a professional seamless install, we arrive with:
Portable gutter forming machine (truck-mounted), aluminum coil in your chosen color and gauge, hidden hangers (every 24" or tighter), end caps, mitered corners, downspout outlets, elbows, and extensions, sheet metal screws and rivets, marine-grade gutter sealant, safety harnesses and ladders, a measuring tape, chalk line, and level.
For DIY sectional installation you'll need sectional gutter pieces, joint connectors, brackets or hangers, drill with hex bits, tin snips, sealant, level, ladder, and safety gear.
The installation sequence
Here's the standard sequence for a residential gutter install:
Measure the roofline. Accurate measurement is everything. Walk the perimeter with a measuring tape, noting every corner (inside and outside), elevation change, and eave length.
Plan the pitch. Gutters need a slope toward downspouts — roughly 1/4 inch per 10 feet. Mark the high and low points with a chalk line along the fascia board.
Install hangers first. Hidden hangers should go every 24 inches, tighter in areas with heavy snow load or long runs. Drive the hex-head screws into the rafter tails behind the fascia, not into the fascia alone.
Form or cut the gutter sections. If seamless, the machine forms a continuous length to your measurement. If sectional, cut sections with tin snips and plan joint locations.
Hang the gutter sections. Set them in the hangers with the proper slope. Seal corners and joints.
Install downspouts. Add outlets, elbows, and downspout pipe. Secure to the home with brackets every 6-8 feet. Extend away from foundation.
Water test. Before the crew leaves, every downspout should be tested with a garden hose to verify flow and check for leaks.
Reno-specific installation considerations
Nevada climate factors change the install:
Snow load — tighter hanger spacing (18" instead of 24") on north-facing elevations prevents sag from Sierra snowmelt ice buildup.
Wind uplift — Fernley, the Carson Valley, and other open areas need heavy-duty hangers rated for higher wind loads.
Thermal expansion — Long runs (40+ feet) in our sun belt need expansion joints to prevent stress buckling.
Downspout sizing — 3×4 downspouts handle monsoon bursts better than standard 2×3 for larger roof areas; we often upgrade.
Why most Reno homeowners call us
A professional seamless install of a typical 180 ft home takes our crew one day and comes with a workmanship warranty. A DIY sectional install takes a weekend, looks sectional, and comes with whatever you paid for the materials. The math usually favors professional install — call (775) 502-1844 for a free quote.
