What is gutter installation?
Gutter installation is fitting a new system of gutters, downspouts and hangers along the roof edges so rainwater is collected and carried away from the house. On most Covina homes today that means seamless aluminum gutters, formed on site from a coil of metal into one continuous piece for each run of roofline, then pitched toward downspouts placed where the water can drain safely.
When you need new gutters
- The house has no gutters, or only covers part of the roofline, and water is eroding soil or splashing stucco.
- You've added a room, patio cover or new roof and the existing gutters no longer fit.
- The current gutters are too small and overflow even when clean.
- You're replacing the roof and want gutters sized and placed correctly at the same time.
- Old gutters are failing beyond repair. If you're weighing that decision, see gutter replacement.
Gutter types and options
The right system depends on the roof, the look of the house and how much water each section has to carry.
Seamless gutters
Seamless gutters are roll-formed at the job site from a coil of aluminum (sometimes steel or copper) and cut to the exact length of each roof edge. Joints only occur at corners and downspout outlets, so there are far fewer places to leak than with sectional gutters, which are joined every 10 feet or so. This is the standard for professional gutter installation in Southern California.
Aluminum gutters
Aluminum is lightweight, won't rust, and comes in baked-enamel colors to match trim or stucco. It's commonly offered in two thicknesses, .027 inch and the heavier .032 inch. Heavier metal resists dents from ladders and holds its shape better on long runs.
Copper gutters
Copper is a premium choice, usually installed as half-round gutters with soldered seams. It weathers from bright metal to brown and eventually green, and is common on historic and high-end homes. Copper is typically specified by weight, such as 16-ounce or heavier 20-ounce copper.
K-style gutters
K-style gutters have a flat back that mounts flush against the fascia and a front profile that resembles crown molding. They're the most common style and carry more water than a half-round gutter of the same width.
Half-round gutters
Half-round gutters are a semicircular trough, often paired with round downspouts. They suit Craftsman, Spanish Revival and Victorian homes, and they're a common choice where the original architecture matters.
5-inch vs. 6-inch gutters
Five-inch gutters handle most residential roofs. Six-inch gutters carry noticeably more water and help on large or steep roof sections, long runs and where roof valleys concentrate runoff. Our guide to 5-inch vs. 6-inch gutters explains how installers decide.
How a gutter installation works
Measuring and planning
The installer measures each roof edge, looks at roof pitch and area, notes valleys and where water concentrates, and decides gutter size and downspout locations.
Checking the fascia
Gutters are only as secure as the board they're fastened to. Soft or rotted fascia should be replaced first. See fascia and soffit repair.
Forming and hanging
Seamless runs are formed on site, fitted with end caps and outlets, and fastened with hidden hangers, commonly spaced every 2 to 3 feet.
Setting the slope
Each run is pitched slightly toward its outlet, often around a quarter inch for every 10 feet, so water doesn't stand in the gutter.
Downspouts and drainage
Downspouts are attached and directed onto splash blocks, extensions or underground drains. See downspout installation and repair.
Sealing and testing
Corners and outlets are sealed, and water is run through the system to check flow.
Installing gutters on Covina homes
A few local factors shape how gutters are installed here. Many San Gabriel Valley homes have clay or concrete tile roofs, where the tiles overhang the edge differently than shingles, so gutter position and hanger choice need care. Some older Spanish-style and Craftsman homes have exposed rafter tails instead of a continuous fascia board, which changes how gutters attach. And because Covina's rain arrives in a few concentrated winter storms, getting the size and downspout placement right matters more than in places with steady, light rain. For a full look at the local picture, see our overview of gutter installation and repair in Covina.
If you're planning gutter guards, it's usually simplest and cheapest to install them with the new gutters, because the installer can choose a guard designed for that gutter profile.
What affects the cost of new gutters
Gutter installation is usually priced by the linear foot, with extra charges for downspouts, corners and add-ons. The biggest factors are material (aluminum, steel or copper), gutter size, the total length of roofline, the number of stories, how many downspouts are needed, removal of old gutters, and any fascia repair. Our gutter installation cost guide breaks these down so you can compare estimates.
Questions to ask before you hire
- What size gutter and downspout do you recommend for each roof section, and why?
- What metal thickness are you quoting?
- What type of hangers do you use, and how far apart?
- Where will each downspout discharge?
- Is removal and disposal of the old gutters included?
- What's your CSLB license number, and what does your warranty cover?
