"Moss Boss did an amazing job on our roof. They were on time, professional, and explained that the dead moss would shed off over the next 3-6 months. Sure enough, by summer it was gone. The 3-year warranty gave us total peace of mind."
"Best roof cleaning experience we've had. They explained the soft wash process, protected our plants, and set clear expectations that the moss would take a few months to fully shed. Honest, professional work."
"Quick to respond, fair pricing, and the team was super friendly. They were upfront that the dead moss takes time to fall off naturally — no scraping that could damage shingles. Already noticing a big difference. Will use again every year."
"Locally owned and it shows — they actually care. No pressure sales, just honest work. Moss is dead and they treated it so it stays gone. They told us it'd take a few months to fully shed and that's exactly what happened."
"Got 3 quotes and Moss Boss was the most knowledgeable by far. They explained that soft wash kills moss at the root and the dead moss falls off over 3-6 months — no shingle damage from scraping. Made total sense."
"Punctual, polite, and thorough. They cleaned up everything when they were done. Honest about the timeline — moss is dead now, rest will shed naturally with rain over the next few months. You can tell they take pride in their work."
