There are many good reasons to do pruning of trees near your home. Insurance companies have become much more stringent about allowing any potential damage to your home, whether it be due to negligence or natural causes.
What to watch out for:
Branches rubbing against roof - This can cause water damage inside the house.
Trees too close to house - Allow easy access for squirrels, raccoons, etc. to get into your eaves and attic
Too much shade - This can cause mold, mildew, and eventually rot
Insect damage - This can kill branches or entire trees, which can fall onto your house or power lines
Heavy snow - Snow can break big limbs and disrupt power for a whole neighborhood in the middle of winter
Drought stress - This can weaken old trees and cause sudden failure
Lack of structural thinning - This can create an overgrown mess that is likely to fail
