Top 5 Most Common Questions about Roof Cleaning

Roof cleaning is a relatively new industry, especially here in Connecticut and the rest of Southern New England, so my team and I hear many of the same questions again and again. Here, then, are answers to five of the most common questions we hear on a weekly basis.

1. Why do I need my roof cleaned?

Roof cleaning improves the quality of your home and can even save you money on your energy bill. When algae, lichen and moss cover a roof they damage the roof, which, if left untreated, can eventually result in the need to have a new roof installed. Cleaning a roof is an investment and a cost saving measure because cleaning a roof vs. replacing a roof represents a significant cost savings.

Cleaning a roof can also save you money on your energy bill. Everyone knows darker surfaces tend to absorb more heat than lighter ones. When your shingles absorb more heat in the summer your air conditioning has to work much harder to maintain the same temperature. Some houses were so bad; after they got a roof cleaning they would save up to 40% on their electrical bill. Houses which have had algae removed will have noticeable savings in the summer months.

2. If roof cleaning is so important, why can’t I just clean my roof myself? Why do I need someone to do it for me?

Our expert technicians have been cleaning roofs throughout Connecticut since 2009. The process of cleaning a roof isn’t as simple as spraying a solution on your roof and letting it dry. We start by spraying a 100% biodegradable solution to the roof killing all the algae organisms growing on the roof. We then follow that up with a low pressure rinse cleaning off all the dead growth leaving you with a spotless roof. We also offer an added roof preventive application, which we apply once the roof has been cleaned, which halts the rapid re-growth of the algae.

3. Do you use a power washer?

Our technicians do not use a power washer at any time. In fact, we never recommend using a power washer on any roof structure.  Our technicians use specially designed pumps that clean off the dead algae. These pumps run at low psi and higher volume; letting the water do the cleaning not the pressure.

4. What are those black streaks on my roof?

Those black streaks are algae called Gloeocapsa magma. This algae is nitrogen fixed and needs no nutrition to grow. The black streaks are the signs of the algae reproducing and leaving millions of dead cells to build up and cause the streak.

5. What happens if it is raining the day the work is scheduled?

A judgment call will generally be made by the owner and a courtesy call made to you by the office staff the morning of if the weather is going to not allow us to clean your roof. We are able to clean your roof in a light rain. We can even apply the roof preventative application in a mild drizzle.
