How to Install Gutters
Gutter installation has gotten complicated with all the sizing options, hanger types, and slope calculations flying around. As someone who has hung gutters on homes of every style, I learned everything there is to know about proper installation. Today, I will share it all with you.
Materials Needed
Probably should have led with this section, honestly—gather these before starting:
- Gutters and downspouts
- End caps and gutter brackets
- Gutter sealant and screws
- Hex head driver or drill
- Measuring tape, level, and ladder
- Chalk line and hacksaw
Measuring and Planning
That’s what makes proper planning endearing to us gutter installers—it prevents costly mistakes:
- Measure the length of roof edges where gutters will be installed
- Decide downspout locations (ideally near corners)
- Mark the slope with a chalk line—half an inch per ten feet toward downspouts
Cutting the Gutters
Cut gutters to required lengths using a hacksaw. Ensure straight cuts for snug fits. Cut before assembling for easier handling.
Assembly
- Assemble gutter sections on the ground
- Attach end caps to each section
- Overlap sectional gutters by a few inches
- Seal joints with gutter sealant to prevent leaks
Attaching Brackets
Mark bracket locations along the fascia board. Space brackets about two feet apart. Secure with screws, ensuring alignment with the chalk line slope.
Hanging the Gutters
Lift assembled sections to the roof edge and secure in brackets. Ensure proper alignment with marked slope for effective water flow.
Installing Downspouts
- Cut holes in gutters for downspout outlets
- Attach outlets and secure with screws
- Connect downspout sections and secure to wall with brackets
- Extend downspouts away from foundation
- Use elbow joints where needed
- Seal all joints with gutter sealant
Testing and Maintenance
Run water through gutters to check flow and identify leaks. Clean gutters at least twice yearly, removing leaves and debris. Check for damage or leaks and repair promptly.
