How to Tell When You Need a New Roof

Water Leaks

Water finds its way through cracks between shingles, along the edges of skylights or chimneys, or under flashing that has become damaged.
In your attic, follow the trail of water up the framing, then go outside and see if there's an obvious spot water is getting in. (Do this in the rain.)
