The Smartest Thing You Can Do Right Now: Trimming Trees to Protect Your Roof This Winter
Here's something most homeowners don't realize until it's too late — the tree you love for its shade in July becomes one of the biggest threats to your roof by December. Trimming trees to protect your roof before the first winter storm hits is one of the highest-return, lowest-cost things you can do this fall. I've seen what overhanging branches do to shingles, gutters, and underlayment after a single wet, windy LA winter. It's not pretty, and it's almost always preventable.
The 6-Foot Rule (And Why Most LA Homes Violate It)
The standard clearance you want between the tip of any branch and your roofline is at least 6 feet — and ideally, no branches should hang directly over the roof at any distance. In Sherman Oaks, Encino, and Calabasas, I see mature eucalyptus, pepper trees, and sycamores with limbs draped across entire roof sections. Homeowners assume that because nothing has fallen yet, nothing will. But branches don't need to fall to cause damage. They scrape. They abrade. Every time the wind moves them, they're sanding the granules off your shingles — the same granules that protect against UV and water infiltration.
What Overhanging Branches Actually Do to a Roof
Here's the damage pattern I see most often:
- Granule loss along the path where a branch repeatedly contacts the shingles — this shows up as bare, shiny patches and accelerates aging by years
- Debris dams where leaves, twigs, and seed pods pile up in valleys and gutters, trapping moisture against the roof deck
- Moss and algae growth in the shaded zones directly under a heavy canopy — shade keeps the roof wet longer after rain, and wet roofs grow things
- Impact damage from smaller limbs that snap in Santa Ana wind events and land on the surface
Any one of these, left alone through a full rainy season, can turn a $400 repair into a $4,000 one.
What to Do Before the Rains Come
Have a licensed arborist trim back any branch within 6 feet of your roofline — and remove any dead or cracked limbs entirely, regardless of distance. Dead wood is the first thing that comes down in a windstorm. While you're at it, clear your gutters of accumulated debris so water has a clean path off the roof.
Then, once the trimming is done, have a roofer take a look at the contact zones. If branches have been rubbing for a season or two, there's a good chance the granule layer is compromised and the shingles need attention before the rain finds the weak spots.
