Why Don’t You Want a Tree Branch Overhanging Your Roof?

Having trees around your home adds ambiance to the space, but one thing you do not want is tree branches actually overhanging your roof. You should have the trees trimmed back every year or two to prevent them from overhanging. But why are overhanging branches such a bad idea? Here are a few reasons.

Algae and Moss Growth

Algae and moss are unique members of the plant kingdom in that they don't love sunlight. They thrive in the shade, and a tree branch casts shade on your roof. Therefore, if a tree branch is overhanging your roof, you are likely to get moss and algae growth up there, neither of which are good for your roof. Moss can cause the shingles to deteriorate, and algae leave ugly black streaks.

Water Damage

When a tree branch stretches over your roof, water will drip down the branch and onto the roof in the same places, again and again. The tree branch may even directly touch the roof, trapping water against it. Even though roofs are designed to tolerate moisture, it is presumed they will dry out in between. A tree branch can prevent this from happening, leading to moisture damage to the roof shingles.

Clogged Gutters

Tree branches come with leaves, and those leaves will inevitably end up in your gutters. With a branch so close, you won't be able to keep up, and you may have clogged gutters often. Not only is having to clean the gutters every few weeks a nuisance, but clogged gutters can lead to shingle damage and even landscape damage from water pouring over the edge.


The sound of a branch scraping against your roof at night will make it sound like a horror film. You may even be woken from your sleep by a loud bang if the wind blows just right and blows the branch into your roof.

Window and Gutter Damage

Say you get a really strong wing that causes the branch to break off. Your roof may survive since it is a sturdy structure, but the branch could drop down against the side of the house and break either your windows or your gutters. 

The truth is clear: if you have a tree with a branch that overhangs your roof, you need to have that branch trimmed back, preferably sooner rather than later. Contact a tree trimming company in your area to make an appointment today.
