Gutters are a common way to handle rain running off a roof, but if your house doesn’t have gutters, you can still keep rainwater away from doors by installing a rain diverter.
A rain diverter is a specially made piece of metal flashing available at home improvement centers that is used to divert rainwater away from a doorway. This not only keeps you from getting wet but prevents the door from deteriorating as well.
To install a rain diverter on your roof:
- Start by cutting the flashing with tin snips about 2-3 feet longer than the doorway you want to protect.
- Next, carefully break the seal on a row of shingles above the doorway with a flat pry bar or putty knife.
- Slide the diverter under the row of loosened shingles.
- Tilt the rain diverter in the direction you would like the water to flow by angling one side down slightly.
- Lift the shingles up and tack the rain diverter down in several places using roofing nails.
- Finish up by putting a dab of roofing cement on each nail head to seal out water and help hold the shingles down.
