# Gutters and downspouts

> Sizing, hanging and fixing gutters. Ask with your Sheet attached: homeowners who’ve done it and verified pros answer, and anyone can read it.

## Before you ask

The roof edge length, the downspouts, and where the water goes.

- **Attach your Sheet** so people see your sizes and the math.
- **Your town is enough.** Never your address; check photos for house numbers and plates.
- **Is it safe?** A safety question here goes to pros verified in roofing, unless you pick another trade. Only they can call it safe or unsafe.

## Gutters and downspouts

84′ of gutter, 4 downspouts: 34 hangers every 32″, 4 downspouts (2×3, 2 × 10′ each) sized for 1503 sq ft of roof, and the corners, caps and outlets.

What people get wrong:

- **Hanging the gutter level, or the wrong way.** Water stands and rots the fascia.
- **Hangers into the fascia only.** A full gutter pulls them out.
- **Joints sealed on the outside.** Water runs under the bead.
