Why gutters matter
Proper gutters protect your foundation, siding, and landscaping by channeling roof runoff away from the house.
- Prevent basement moisture and erosion
- Protect fascia and siding from splash-back
- Reduce soil erosion near the foundation
Sizing and capacity
Most U.S. homes use 5-inch K-style gutters; high-rain regions may need 6-inch and extra downspouts.
- Match capacity to roof area and local rainfall
- Add downspouts every 30–40 feet on long runs
- Check local building codes
Pitch and materials
Gutters need about 1/4 inch slope per 10 feet toward downspouts. Aluminum is popular; steel and copper last longer.
- Secure hangers every 2 feet
- Aluminum — lightweight, rust-resistant
- Vinyl — budget-friendly but can warp in heat
Gutter guards and maintenance
Guards limit leaf buildup but still need twice-yearly inspection. Extend downspouts 4–6 feet from the foundation.
- Micro-mesh blocks small seeds; screens suit light leaf load
- Clean gutters after heavy storms
- Trim overhanging branches
Hiring a gutter contractor
Licensed contractors should include haul-away and a workmanship warranty. Get three written quotes.
- Ask about seamless vs sectional runs and how corners are formed
- Confirm whether guards are priced as a separate line or bundled
- Require haul-away of old gutters and a written workmanship term
Gutters fail at outlets and seams, not in the middle of a pretty run
A seamless run that dumps at the foundation is worse than old sectional gutters that carried water 6 feet away. Size the downspout to the roof area and the leaf load. Guards help; they do not replace a twice-yearly look after storms.
- Extend downspouts so soil next to the slab stays dry
- A sagging fascia means fix wood before hanging new aluminum
- Hidden hangers and pitch toward outlets should be visible on a ladder inspection
