There are other risks from trees being close to a home. For example, a trees branches or limbs could fall on the roof or power and communication lines. They could also easily fall and hit someone, causing injury. This risk is increased even more if the tree is old or dying. Falling leaves and branches could clog up gutters and downspouts which could start to create structural issues if left untreated. Insects and rodents would be able to gain easier access into the home and there is danger from fire, especially in an area at risk of wildfires.
Yes, there are certain risks associated with trees being positioned too close to a building. This is something you might wish to think about if you are building your own home. If there are trees close to your home, why not have a periodic check of them to make sure they are still healthy. A dead or dying tree would pose a greater danger and may need to be removed altogether.
