Material Selection Guide
Most popular choice. Matches standard white K-style gutters directly off the roll. Lightweight, corrosion-resistant, UV-stable factory finish. Ideal for all residential installs.
Natural aluminum surface, ready for custom paint or coating. Recommended when gutters will be field-painted to match a specific exterior color scheme.
Maximum strength and rigidity. Preferred for commercial buildings, steep-pitch roofs, and installations with heavy debris or snow load. Hot-dip galvanized for rust resistance.
Specified for copper gutter systems on luxury residential and historic properties. Develops a natural patina over time. Must be soldered to copper gutter for a watertight seal.
Installation Overview
- Mark outlet location — measure and mark the downspout drop point on the gutter bottom, typically 6 to 12 inches from the end cap, positioned to align with downspout brackets.
- Cut the drop hole — use a hole saw or aviation snips to cut a 3-inch round hole in the gutter bottom at the marked location.
- Deburr the opening — file or sand any sharp edges around the cut hole to prevent outlet damage and ensure a flush seat.
- Apply sealant — run a bead of gutter sealant or roofing caulk around the underside flange of the outlet before inserting.
- Insert and seat the outlet — push the outlet up through the hole from below until the flange sits flush against the inside of the gutter bottom.
- Secure with rivets or screws — fasten the outlet flange to the gutter with 4 to 6 aluminum pop rivets or sheet metal screws for a permanent, watertight connection.
- Connect the downspout — slide the top of a 2x3-inch rectangular downspout over the outlet neck and secure with sheet metal screws on two sides.
- Test with water — run water through the gutter to confirm drainage and check for leaks at the flange joint.
