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: Can roof cleaning prevent the need for repairs?

• <div><p>Yes, cleaning removes harmful elements that contribute to rot or degradation, extending the roof's lifespan and averting costly future repairs.</p></div>

Q: What is the best way to remove snow from your roof?

• <div><p>There are several <a href="https://www.angi.com/articles/tips-removing-snow-and-ice-your-roof.htm">ways to remove snow from your roof</a>: using a snow rake, salting the roof with calcium chloride, using a rope (cautiously), and using heating cables. It&rsquo;s important to mention that pretty, fluffy, sparkling snow weighs a great deal, and when physically removing snow from a roof, you should be aware of large snow slabs breaking off. These can weigh hundreds of pounds and are a real danger, so be extremely careful anytime you&rsquo;re doing this type of work. </p></div>

Q: How do you make old shingles look new?

• <div><p>If you wish to forego painting your shingles but still want to give them a fresh look, a deep cleaning is the first step. Clean off any debris from your roof and gutters, and then power wash your shingles to get grime and algae off. To take things one step further, you might even consider installing new gutters to give your home a bright new look.</p></div>

Laman's Roofing & Gutters did an excellent job replacing a roof for me and also repairing some siding. The communication was rapid and professional before and after the job was done. I have recommended them for friends in addition to hiring them for another job myself. Great work.

Excellent! Roofing crew was excellent. They were on time all 3 days. Started working immediately, all were very polite and professional. Mike Peranich and Tom Shelp were a real pleasure to work with. Everything was very neat and clean when they left. Would definitely recommend.

Everything thing went very well. Kevin, the owner of the business, gave me a quote on Mon. He said they had an opening on Thursday. They actually came two hours early, rather than go to lunch in between appointments. They sprayed and washed and scrubbed the roof free of all mold, lichen and...

The gutter repair was fine. The cleaning is a different story. The men were sloppy - throwing debris everywhere and not as thorough as it should be for $250. I did not complain at the time because the job was done and at least my husband didn't have to climb on the roof. However, now one...

The roofers arrived promptly, worked efficiently and cleaned up afterward to our satisfaction. They did ask if they could arrive at 6am due to the heat of the day, and stated they would try to keep it quieter until 7a.m. We are very pleased with the roof.
