How to Install Rain Gutters
The following instructions are intended to provide a general overview of the gutter installation process for planning purposes. Your steps may vary greatly depending on the products you use and the layout of your roof. Always defer to the manufacturer’s instructions for any tools and materials involved. You’ll also need to enlist a helper for this project.
Step 1: Measure Your Roofline
- Set your ladder on stable, level ground and position it securely. For help, see our ladder safety instructions.
- Measure the length of each roof edge (fascia) where the gutters will be installed.
Step 2: Choose the Right Gutters
- Standard residential sizes are 5-inch and 6-inch K-style gutters.
- Common materials include aluminum, vinyl and galvanized steel and copper.
- Choose materials based on durability, budget and appearance.
Larger or steeper roofs shed more water and may require wider gutters (typically 6-inch instead of 5-inch). For more on choosing gutters, see our buying guide.
Step 3: Plan Downspout Locations
- Place downspouts at corners and at least every 30 to 40 feet along the gutter run to ensure appropriate drainage and prevent rainwater from spilling over the sides of the gutters.
- Mark the spout locations with chalk.
- Plan to direct water at least 3 to 5 feet away from the foundation.
Step 4: Set the Slope and the Install Hangers
- Gutters should slope about 1/4 inch for every 10 feet toward the downspout.
- Snap a chalk line to use as a guide for the placement.
- Install hangers every 24 to 36 inches. Use closer spacing if you live in an area with heavy snowfall).
- Fasten the hangers securely into the fascia board using exterior-rated screws.
Step 5: Cut and Install the Gutters
- Cut gutter sections to size using a hacksaw or tin snips.
- Attach sections together using connectors or slip joints.
- Seal seams with gutter sealant according to the manufacturer’s instructions to prevent leaks.
- Snap or fasten gutters into the hangers.
Step 6: Install Downspouts
- Cut a hole in the gutter for the outlet if one isn’t already pre-cut.
- Attach the outlet fitting with screws and sealant.
- Connect downspout sections and elbows to reach the ground.
- Secure the downspouts to the wall using downspout straps.
Step 7: Direct Water Away from the Foundation
- Ensure water is discharged 3 to 5 feet away from the foundation.
- Add downspout extensions or splash blocks if needed.
- After installation, run water through the system with a hose to check flow and leaks.
