Here's a tip on how to increase the life of old wooden gutters. The first step is to lay a new rubber liner along the inside the gutter. Adding copper flashing along the edge seals the liner, adds extra durability, and allows water to run off easily. Finally, add a second strip of rubber on top of the flashing for extra protection.
When repairing smaller tears in roof shingles, apply a thin bead of roof cement both under and over the tear, then smooth out the top bead with a putty knife. To camouflage the repair, collect some of the color chips that have washed from the shingles into the rain gutters and sprinkle them over the cement.
