Q: What are signs I need a professional roof cleaning?

• <div><p>Even though you don&rsquo;t look at your roof often, there are some telltale signs that you should have your roof professionally cleaned. It&rsquo;s best to hire a professional roof cleaner as soon as you notice signs of wear and tear to preserve the essential feature&rsquo;s longevity. Some indicators to look out for include:</p><ul><li><p><a href="https://www.angi.com/articles/why-gutter-cleaning-so-important.htm">Leaf buildup in gutters</a></p></li><li><p>Dirt and grime buildup</p></li><li><p>Moss or black algae growth</p></li><li><p>Dirt buildup under shingles</p></li><li><p>Shifting roof shingles</p></li><li><p>Plant growth</p></li></ul><p></p></div>

Q: How often should I have my roof cleaned?

• <div><p>A professional roof cleaning lasts about a year on average, so it&rsquo;s best to do it annually. This schedule helps catch any roof problems before they become extensive and helps prevent mold, moss, and algae from forming. If you live near the coast, annual roof cleaning will help prevent salt buildup on your roof. You can add professional roof cleaning to your yearly <a href="https://www.angi.com/articles/spring-home-inspection-checklist.htm">home maintenance checklist</a> to ensure you never miss a year. </p></div>

Q: Do repairs include cleaning?

• <div><p>Yes, many services include cleaning as part of the repair process. Confirm with your provider.</p></div>

Q: How often do solar panels need to be cleaned?

• <div><p>You should clean your panels at least twice a year. It depends on your location. In dusty climates (think the Arizona desert), you may need to clean your panels more frequently. Dust can dramatically impact the electrical output. If you live in a climate with extreme weather, you may want to check your panels seasonally.</p></div>

Q: Can you softwash with a pressure washer?

• <div><p>Yes, you can, but you&rsquo;ll need to acquire the right pressure washer tips and cleaning solutions for the job. In particular, you&rsquo;ll need tips that are capable of lowering the pressure from a max of 3,500 PSI to between 150 and 300 PSI. As for the cleaning solution, look for options that are clearly marked for soft washing rather than pressure washing. </p></div>
