Trim trees near house

Trim branches near your home to protect your roof and siding from damage.

Why it matters#

Overhanging branches drop debris, hold moisture against your roof, provide pest access, and can cause serious damage during storms. Regular trimming protects your home.

What you'll need#

Tools#

Bypass pruning shears (for branches under 1/2 inch)
Lopping shears (for branches 1/2 to 2 inches)
Pruning saw (for branches over 2 inches)
Pole pruner/saw (for high branches)
Safety glasses
Work gloves
Ladder (if needed)

Steps#

1. Identify branches that need trimming#

Look for branches touching or within 3 feet of your roof, siding, windows, or power lines. Also identify dead, damaged, or diseased branches.

2. Check for power lines#

Never trim branches near power lines yourself. This is strictly utility company or professional arborist work.

3. Plan your cuts#

Decide which branches to remove. Avoid removing more than 25% of a tree's canopy in one year.

4. Start with dead or damaged branches#

Remove these first. They're priorities because they can fall unexpectedly and cause damage.

5. Use the three-cut method for large branches#

For branches over 2 inches: First cut: undercut 12-18 inches from the trunk, about 1/3 through. Second cut: top cut a few inches further out—the branch will fall cleanly. Third cut: remove the stub just outside the branch collar.

6. Make clean cuts#

Cut just outside the branch collar at a slight angle. Don't cut flush with the trunk or leave long stubs.

7. Clear branches from roof#

Trim branches that overhang or touch the roof—they drop debris, hold moisture, and provide pest access to your home.

8. Maintain clearance from siding#

Keep branches at least 3 feet from siding to prevent scratching during wind and allow airflow.

9. Clean up debris#

Rake up fallen branches and leaves. Dispose of properly—many areas offer yard waste pickup or drop-off.

Pro tips#

Late winter (while dormant) is the best time to prune most trees
Never top a tree (cutting the main trunk)—it damages the tree and causes weak regrowth
Clean pruning tools with rubbing alcohol between trees to prevent spreading disease
Keep a clear view of your home from the street—trimming improves both curb appeal and security

Warnings#

Never trim near power lines—call your utility company or a licensed arborist
Don't climb trees with a chainsaw or work above your comfort level on a ladder
Large limbs can be unpredictable when falling—clear the area below before cutting
Some trees (like oaks) shouldn't be pruned in certain seasons due to disease risk

When to call a pro#

Hire a certified arborist for: branches near power lines, branches higher than you can safely reach from the ground or a stable ladder, large branches (over 4 inches diameter), any work requiring a chainsaw in a tree, or unhealthy trees that need diagnosis. Professional trimming typically costs $200-1,000+ depending on the scope.
