Saying About Our Roof Cleaning
Roof Cleaning in Nashua NH
Zack and Avery were awesome! Their office set me a text notifying me that they were arriving in 30 minutes at 0800. They arrived on time, explained to me their game plan and proceeded to remove the mold off my roof. After the job was finished, they thoroughly explained what they did. They assured me that they watered down all the scrubs and vines on my house to neutralize the solution they used on the roof. I highly recommend AM Pro Wash and will add them to my list of 5 Star companies!

Can't say enough good things. Very professional from the first visit to give an estimate. Explained everything answered all our questions. I was a little nervous about my extensive gardens and they were so careful and respectful. The house and roof came out amazing and the gardens were still in great shape. Thank you so much. I would highly recommend them. We love keeping our business local.

What Causes Black Streaks On Roofs?
The dark streaks you see on roofs are typically caused by roof algae.
Over time this bacteria spreads across shingles and creates the streaking pattern many homeowners notice.
Because New England has humidity, shade, and organic debris, roofs in Massachusetts and Southern NH are especially prone to this problem.
Why You Should Not Pressure Wash a Roof
Many homeowners consider pressure washing when they see roof streaks.
Unfortunately, high pressure can damage shingles and shorten the lifespan of the roof.
Professional roof cleaning uses a soft washing method that safely removes the bacteria without harming the roofing material.
