Roof cleaning sounds crazy, I know, but cleaning roof shingles is a task that many homeowners
0:06
are faced with. Heck, look at the moss, lichens and algae on my own roof

Hi, I'm Tim Carter from AskTheBuilder.com and today I want to demonstrate how to safely
0:16
use a pressure washer to clean asphalt shingles. A pressure washer can damage roof shingles
0:28
You must use the correct spray wand tip when you do roof shingle cleaning
0:32
In my opinion, I feel the best tip to use is the 25 degree tip
0:37
It'll produce a fantastic stream of water to dislodge moss, lichens, and algae, but
0:42
it's not so powerful as to ruin the shingles. Try to stand on a dry portion of the roof when you work
0:49
Wet shingles can be really slippery. Always aim the pressure washer down the roof
0:54
aim it up the roof as it can blast water under the shingles and create leaks into your home
1:01
Keep the tip of the pressure washer wand at least 12 inches away from the shingle surface
1:06
when you begin cleaning Just clean off one shingle when you start and inspect closely to see if the pressure washer is stripping away any of the colored granules off the shingles Adjust the distance between the spray wand tip and the roof shingles to get maximum cleaning
1:22
and no shingle damage. Constantly stop and inspect the shingles to make sure all is well
1:29
Oh, yeah. Oh, sweet. Check it out. Look at this roof. It's clean
1:38
moss, lichens and algae are all gone and you know what? These shingles are 20 years old
1:44
and they're not damaged. You can clean roof shingles safely with a pressure washer. Take
1:50
your time. I'm Tim Carter for AskTheBuilder.com. If you want to discover more home improvement
