Gutters and Downspouts: A Small Part That Protects the Whole House

The Short Answer
Gutters and downspouts collect roof water and move it away from the home. When they fail, water can damage siding, foundations, and basements.

What they do
Gutters catch water at the roof edge, and downspouts carry it down and away. Without them, water pours next to the foundation and splashes onto siding.
Common materials
Key point
What it means
Aluminum
The most common, lightweight and rust-free.
Galvanized steel
Stronger but can rust over time.
Copper
Long-lasting and expensive.
Vinyl
Inexpensive, but can become brittle in sun and cold.
Quick Poll
Have you ever dealt with a gutter or downspout problem?
You are not alone. Get the findings in writing from a licensed professional, keep photos and receipts, and if you are buying, use the report as a negotiation point before your inspection deadline. Talk with David if you want a second opinion on what matters.
Good news, but this is exactly the kind of issue that can stay hidden until someone looks. Add it to your inspection checklist or ask your inspector about it before you buy or sell.
That is very common. The simplest way to know is to have it checked. Ask David which inspections are worth adding for the home you are considering. Talk with David.
What to look for
Sagging runs, pulling away from the fascia, standing water, seam leaks, clogs, missing downspout extensions, and stained siding below. Check the fascia boards behind gutters for rot.
Maintenance tips
Clean gutters in spring and fall, especially if you have trees. Make sure downspouts discharge at least several feet from the foundation. In snowy areas, watch for ice dams, which form when heat escapes through the roof and melted snow refreezes at the edge.
