8 critical home repairs you can't ignore

Untrimmed trees

You know you've got a problem when: You can hear limbs brushing against the walls or roof in a storm.

What causes it: Untrimmed trees or large bushes growing too close to the house.

The worst that can happen: The limbs break shingles or siding, allowing water into the house, causing rot and mold.

Fix it yourself? It's possible if you can use the ladders and saws required to reach and remove the offending branches.

Who should you call? Call a tree service if you're not steady on a ladder or have to remove branches that are so large they'll be tough to control when they're cut. (That can require ropes and skills not many homeowners possess.)
