Q: Should you use a pressure washer on the roof shingles?

• <div><p>If you&rsquo;re asking yourself, <a href="https://www.angi.com/articles/can-roof-cleaning-extend-life-my-shingles.htm">should you pressure wash your roof</a>, the answer almost always is no. The water pressure that the power washing machine generates could damage the shingles by forcing water underneath or causing them to loosen. Soft washing with a pump sprayer is the better and safer option.</p><p> </p></div>

Q: Do algae-resistant shingles prevent moss?

• <div><p>Yes, algae-resistant shingles will prevent algae and moss growth, providing double protection for your roof and <a href="https://www.angi.com/articles/what-is-roof-flashing.htm">roof flashing</a>. The copper-infused granules on algae-resistant shingles release copper ions that inhibit plant growth in general, so moss will have a harder time growing on your roof, too. Keep in mind that copper ions flowing off your roof during rainfall can also inhibit plant growth below, so your gardens and grass may be affected.</p></div>

Q: What time of year do you remove algae from a roof?

• <div><p>Ideally, you will tackle removing algae from your roof during spring or summer when the weather is drier and warmer. Because algae tends to grow during the colder and wetter months, you want to tackle this project before the temperature drops to hopefully keep it from coming back at all.</p></div>

Q: Are there any risks associated with roof cleaning?

• <div><p>Risks include slipping, shingle damage, or chemical misuse. Professionals ensure safety and proper procedures to minimize these hazards.</p></div>
