Roof & siding · 01Before you ask

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.
Roof & siding · 02Gutters and downspouts

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.
