How Trees & Local Environment Impact Your Roof

Have you ever wondered what effect trees and the environment have on roofs? What causes tree damage to roofs? What happens when tree roots start moving through drainage systems or the cracks in a roof’s asphalt shingles when roots grow close to the gutter? How do certain conditions like harsh winters cause more damage than others? It is imperative to understand the effect of trees and the environment on the roof to protect it.

Impacts on the roof

Damage to plaster, shingles, and gutters from tree limbs

Fallen limbs can not only break shingles and cause leaks, but they can also snap roof trusses and collapse the roof if they are large enough. In addition to doing significant structural damage, falling limbs can cause minor damage to the exterior of houses. Branches hitting the house can leave scratch marks, dent siding, windows, and cracked tiles on the roof or patio. If you live in an area with many trees nearby, it is important to keep up with your roof cleaning, so none of this happens to you.

Another way that trees can damage your roof is through their leaves. The leaves are naturally acidic, and over time they will wear down the protective coating on your roof. This will begin to leak, allowing water to come into contact with your roof and also letting in moisture that can cause mold to grow in areas where it shouldn’t be.

Moss and mildew growth

Moss is a living plant that grows on the roof of your home. Moss is primarily made up of water, which can cause it to grow if there is an overflow or leakage from your attic. Moss tends to grow in damp or shady areas of your roof. For example, you may find it growing near the chimney, skylight, or vents.

Mildew is a fungus that takes hold of your roof even when it is not leaking. Mildew thrives in warm and moist areas, so you will likely notice it in corners and around skylights. Both moss and mildew can be very destructive to your roof and shingles, and they are best removed as soon as possible by our Bucks County roofing contractors to prevent further damage.

Effect of high heat on the roofing materials

Heat is a significant factor in how long your roof lasts; after all, asphalt and shingles get soft when the weather gets hot. The biggest culprits in heat-related damage to asphalt shingles are ultraviolet light (UV) and infrared radiation (IR).

IR causes asphalt shingles to expand, while UV causes them to stiffen and crack. In extreme cases, this leads to cracking and blistering the entire roof.

Leakage

If branches fall on your roof, they can cause leaks and other damages that require roof repair.
