Well installed gutters protect the roof edge, the walls, the landscaping and the foundation. Getting the size, slope and downspout placement right matters as much as the gutters themselves.

Choosing new gutters
Seamless gutters
Made on site from one long piece, with fewer joints that can leak.
Sectional gutters
Joined pieces that are easier to replace in parts.
Size
Larger gutters and downspouts carry more water, which helps on big or steep roofs.
Guards
Screens and covers reduce clogs from leaves and debris.

How gutters are installed
- Old gutters are removed, and the fascia is checked and repaired.
- New gutters are sized for the roof and rainfall.
- Gutters are hung with a slight slope toward the downspouts, often about a quarter inch for every 10 feet.
- Hangers are fixed at regular spacing so gutters do not sag.
- Downspouts and extensions carry water well away from the foundation.
Getting the most from new gutters
- Clean gutters at least twice a year
- Make sure downspouts discharge several feet from the house
- Check hangers after storms
- Trim branches over the roof
- Consider guards if trees drop a lot of leaves

Questions to ask before you hire
- Seamless or sectional, and why?
- What gutter and downspout size do you recommend?
- How will you slope the gutters?
- Will you repair rotted fascia first?
- What warranty covers materials and labor?
