How Can Trees Cause Damage to Your Roof?

Trees can benefit your property in many ways. They provide shade on hot days, they protect your home from high winds and they help prevent soil erosion. However, trees can also cause damage to your home under certain conditions. In today’s post, local roofing contractor Mascon, Inc. shares how you can prevent this type of damage.

Tree-Related Damage

Tree roots are not strong enough to pierce house foundations, but they can grow into existing cracks. Large, wide root systems can extend beneath the house, which can result in uplift. Roots may also cause moisture imbalance in the soil as they absorb moisture. This can result in the house settling as the soil loses its elasticity.

Tree branches can also damage roofing systems. Sharp branches may touch the roofing surface and scrape its protective outer layer. On asphalt shingle roofs, stripped outer granules can expose the asphalt-soaked backing material to damage caused by UV rays. On metal roofs, sharp branches can strip and peel the outer coating and expose the bare metal to corrosion. On flat roofs, tree branches can cause tears on the singly-ply layer and expose the underlying layers to moisture infiltration. Also, leaves and needles may clog the gutters, which can later lead to moisture infiltration from overflowing rainwater.

How to Prevent Damage Caused by Trees

It’s important to have enough clearance between the tree branches and the roofing surface. There should be about 10 feet of clearance, which should provide enough allowance for growth. Keeping the tree branches trimmed can also prevent small animals from gaining access to your rooftop. If you do not know how to trim tree branches without harming the tree itself, a local arborist can do it for you.

Tree roots can be managed by putting root barriers between them and the house foundation. Ideally, root barriers should be installed at the same time the tree (or other greenery) is planted. Installing barriers along fully grown trees may require the help of an arborist or a professional landscaper. If damage has already occurred on the house foundation, contact a house foundation specialist.
