Tree roots and the trees can be a beautiful thing! However, when they are planted in the wrong location or not properly maintained, they can cause havoc with your home.
Trees can provide plenty of shade and even cool down your house. Often, they get planted to close to the house (see picture above) potentially creating problems with the house, foundation and plumbing. Troubles can arise however when their branches are in contact, approaching or overhanging your roofline. They can cause damage your roof, promote moss / algae / lichen growth on the shingles and prematurely wear your shingles too. It’s also an indicator that the tree’s “dew / drip” line (or tree roots) are knocking at your foundation wall and can cause not only damage to it but sewer lines too.
Properly trimmed trees and “lifting” tree branches away from your house / roof can still provide its cooling effects and reduce the potential for damage to your home.
