How to Clean Roof Valleys

By Mark J. Donovan

In this video Mark Donovan of shows how to clean roof valleys to prevent ice and water damage during the winter months.

Allowing leaves and pine needles to sit on your roof all winter is a recipe for disaster. Water and ice can build up and work their way under the roof shingles and damage the shingles. In addition, water can back up behind the shingles and enter into the home’s attic causing water damage throughout the house.

Steps for Cleaning Roof Valleys

Using a roof rake, some Wet and Forget, and a leaf blower, you can clean your roof valleys in short order.

To clean your roof valleys start by using a roof rake to remove the leaves and crusted pine needles. 

Then use a leaf blower to blow off any of the small and loose leaf and pine needle debris.

Finally, apply some wet and forget on the roof to kill off any of the moss, mold and mildew that is residing on the roof.

The entire process for cleaning your roof valleys, and the rest of the roof, should take no more than an hour.

Just make sure you’re safe and use a ladder that is in good condition and securely placed on the ground and resting snugly up against the house roof.
