How to Replace Gutter Hanger Screw
To replace gutter hanger screws, remove the loose or damaged screws, line the hanger back up, and drive matching exterior-rated replacement screws into solid wood so the gutter sits tight and supported again.
This is a good repair when a section of gutter is sagging, a hanger has pulled away, or the old screws are rusted, stripped, or missing. The goal is not just to put a new screw in the same hole, but to make sure the hanger is fastened into solid backing so the gutter can carry water without dropping again.
Before you start: Match the screw type, length, head style, and material rating before ordering.
Safety first
- Work from a stable ladder on firm, level ground and avoid overreaching.
- Wear gloves because gutter edges and old screws can be sharp.
- Do not work on gutters during high wind, storms, or when the ladder feet may slip on wet ground.

Step-by-step fix
Step 1: Confirm the hanger screw is really the problem
- Look along the gutter and find the exact hanger that has dropped, pulled loose, or shifted out of line.
- Check whether the screw is missing, visibly rusted, bent, stripped, or spinning without tightening.
- Press up gently on the sagging gutter section to see whether the hanger itself is still usable and the gutter shape is still mostly intact.
- Look behind the hanger area for obvious rot, split fascia, or wood that has crumbled around the old screw hole.
If it works: You have confirmed the gutter hanger screw is the failed part and the hanger can likely be resecured.
If it doesn’t: If the hanger is bent, the gutter is torn, or the wood behind it is damaged, fix those issues first or replace the damaged hardware instead of only changing the screw.
Stop if:
- The fascia or mounting surface is soft, rotten, split through, or pulling away.
- The gutter section is badly bent or torn around the hanger.
- You cannot set the ladder safely on firm, level ground.
Step 2: Set up safely and match the replacement screw
- Place the ladder on stable, level ground and position it so you can work without leaning far to either side.
- Put on gloves before handling the gutter edge and old fasteners.
- Remove one intact screw from a nearby hanger if needed so you can compare length, diameter, head style, and thread type.
- Choose an exterior-rated replacement screw that matches the original style closely enough to fit the hanger and bite into solid wood.
If it works: You are set up safely and have a replacement screw that fits the hanger and the mounting surface.
If it doesn’t: If you are unsure about the size, take the old screw to a hardware store and match it before installing anything.
Stop if:
- The replacement screw head does not fit the hanger opening or driver bit properly.
- The only screws available are not rated for exterior use.
Step 3: Remove the failed screw and realign the hanger
- Back out the loose or damaged screw with the correct driver bit.
- If the screw is missing, clear dirt and debris from the hanger hole so the new screw can seat flat.
- Lift the gutter gently until the hanger sits where it originally supported the gutter run.
- Hold the hanger snug to the fascia or mounting surface so the screw will start straight.
If it works: The old fastener is out and the hanger is lined up in the correct position.
If it doesn’t: If the hanger will not sit flat or the gutter stays twisted, straighten the hanger or reposition the gutter before driving the new screw.
Stop if:
- The old screw is seized and begins tearing the hanger or gutter metal during removal.
- The hanger cracks or separates while you are repositioning it.
Step 4: Drive the new screw into solid backing
- Start the new screw by hand or at low drill speed so it goes in straight through the hanger hole.
- Drive the screw until the hanger is snug and the gutter is supported, but do not overtighten and crush the metal or strip the wood.
- If the old hole no longer holds, move to the hanger's alternate hole if available or shift to solid wood immediately adjacent to the failed hole while keeping the hanger aligned.
- Replace any other nearby screws that are badly rusted or obviously loose while you are on the ladder.
If it works: The hanger is tight, the screw is seated cleanly, and the gutter no longer drops at that point.
If it doesn’t: If the screw keeps spinning or will not tighten, the wood behind the hanger is likely damaged or the screw is the wrong size.
Stop if:
- The screw will not bite into solid wood after a reasonable repositioning attempt.
- The fascia flexes noticeably or breaks apart as the screw tightens.
Step 5: Check the gutter line and support spacing
- Step back and sight along the gutter to make sure the repaired section follows the same line as the rest of the run.
- Push up and down lightly near the repaired hanger to confirm it feels supported instead of springy.
- Inspect the next few hangers on both sides for loose screws, widening holes, or signs that wind or water load has stressed more than one fastener.
- Tighten or plan to replace additional failing screws before they let the gutter sag again.
If it works: The repaired area is aligned with the rest of the gutter and the nearby supports look stable.
If it doesn’t: If the gutter still sags between hangers, inspect for additional loose hangers or a section that needs more than one screw replaced.
Stop if:
- Multiple hangers have pulled loose from damaged wood along the same run.
- The gutter pitch looks wrong enough that water would likely stand after the repair.
Step 6: Test the repair in real use
- Run water from a garden hose into the gutter upstream of the repair, or wait for the next steady rain and watch the area closely.
- Check that the repaired hanger stays tight while the gutter fills and drains.
- Look for fresh movement, screw loosening, or water spilling over because the gutter is still out of line.
- Recheck the screw after the test to make sure it stayed snug.
If it works: The gutter stays supported under water load and the new screw holds without loosening.
If it doesn’t: If the hanger loosens again, the root problem is usually stripped or rotten backing, a damaged hanger, or a gutter section that needs broader repair.
Stop if:
- The gutter pulls away again during the water test.
- Water exposure reveals hidden rot, separation, or failure along the mounting surface.

FAQ
Can I just put a bigger screw in the same hole?
Sometimes, but only if the new screw still fits the hanger properly and bites into solid wood. If the old hole is stripped and the wood is weak, a bigger screw alone may not hold for long.
What kind of screw should I use for gutter hangers?
Use an exterior-rated screw that matches the original length, head style, and general screw type closely enough to fit the hanger and resist weather exposure.
Why did the old gutter hanger screw pull out?
Common causes are wind load, heavy water or debris weight, rust, stripped wood, or repeated movement from a sagging gutter section.
Do I need to replace more than one screw?
If nearby screws are rusted, loose, or starting to pull out, it is smart to replace them while you are already set up. One failed screw often means others are not far behind.
What if the new screw will not tighten?
That usually means the backing wood is stripped, rotten, or split, or the screw is not the right size. At that point, the repair needs more than a simple screw swap.
