Common Gutter Problems and DIY Fixes

Overflowing Gutters

Overflowing gutters occur when water spills over the edges instead of flowing through the downspouts. This can be caused by a simple clog, undersized gutters, or improper installation.

Clogs: Debris such as leaves and twigs can block the gutters or downspouts, causing water to overflow. Clean the gutters regularly to prevent clogs.
Undersized gutters: Gutters that are too small for the volume of water they need to handle can also overflow. Consider installing larger gutters if you experience frequent overflows.
Improper installation: Gutters that are not installed at the correct slope or with adequate support can also cause overflows. Ensure that the gutters are sloped towards the downspouts and that they are securely attached to the fascia board.

How to Fix Overflowing Gutters:

Install a diverter to direct water evenly down the sides of the gutter.
Replace undersized downspouts with larger ones.
Install gutter aprons to prevent water from overflowing behind the gutter.

Sagging Gutters

Sagging gutters can occur when the gutter hangers loosen or the fascia board rots. This can cause water to pool in the gutters, leading to further damage.

Loose gutter hangers: Hammer the gutter spikes back into place to secure the gutters.
Rotted fascia board: Replace the rotted fascia board with a new one made of PVC or another durable material.
Temporary fix: Wedge plastic shims between the back of the gutter and the fascia board to level it out.

Tightening Loose Downspouts

Loose downspouts can pull away from the gutters or the house, causing water to leak.

Gutters: Fit a downspout drop outlet into the gutter and seal it with gutter sealant. Secure it with gutter screws.
House: Attach the downspout to the house with gutter straps.

Sealing Gutter Leaks

Gutter leaks can occur at seams, end caps, holes, or separating joints.

Seams: Apply new sealant to both sides of the seam.
End caps: Tap the end caps back into place and seal with gutter sealant.
Holes: Cut a patch from flashing material and cement it into place with gutter sealant.
Separating joints: Reattach the gutter slip connectors or tap the gutter back into place.

Clearing Out Clogs

Gutters and downspouts can become clogged with leaves, twigs, and other debris. This can prevent water from flowing properly, leading to overflows and other problems.

Access the gutters: Use a ladder to reach the gutters and locate the clog.
Remove the clog: Use a hose to flush out the clog or disassemble the elbows from the downspout and clear them individually.
Prevent future clogs: Install gutter guards to keep debris out of the gutters.

Correcting the Slope

Gutters should be sloped towards the downspouts to allow water to flow freely. If the slope is incorrect, water can pool in the gutters, causing damage.

Remove the gutters: Remove the gutters and mounting brackets.
Reinstall with proper slope: Adjust the gutter brackets to ensure a slope of 1/8-inch to 1/2-inch vertical drop per 10 feet horizontal.
Replace fascia if needed: If the fascia is damaged or rotten, replace it before reinstalling the gutters.

Installing Gutter Guards

Gutter guards help prevent debris from entering the gutters, reducing the risk of clogs and overflows.

Choose the right guards: Consider mesh or solid gutter guards that fit over the tops of the gutters.
Attach the guards: Secure the gutter guards with brackets or other fasteners.

Repairing Broken Sections

Certain parts of gutters can become damaged or broken and need to be repaired or replaced.

Spikes and fascia hanger brackets: Replace warped spikes with fascia hanger brackets to securely hang the gutters.
Damaged seamless gutter: Use a slip joint to replace a damaged or dented part of a seamless gutter.
Downspout: Replace a battered downspout splash guard with a retractable one that can be rolled up out of the way.
Rust spots: Repair rusty spots with roof and gutter repair tape.

When to Call a Professional

Consider hiring a professional gutter installer for repairs or replacements if:

Your house is very tall and the gutters are high up.
You have extensive gutter damage.
You are not comfortable working at heights.

How Often to Replace Gutters

Gutters typically last around 20 years. However, they may need to be replaced sooner if they are severely damaged or if they are not properly maintained.
