2.) Ensure the Health of the People Inside

Power washing your roof can have a significant impact on the health of the people who live inside your home. When a roof is neglected, the mold and algae growth on it can become excessive, and spread from your roof and into the attic area. This can raise health concerns by causing allergies to the people living there. Also, these organisms can interfere with your air conditioning system and the toxins created by them can easily be breathed in causing respiratory problems. Furthermore, the build-up of fallen leaves, dust, and dirt can attract insects and rodents that can make their way into your home through loose roof shingles.

3. Increased Roof Longevity

Power washing a roof helps prolong its lifespan and preserve its shingles or tiles. Moss and algae have a tendency to build up as years go by, and if they are not removed regularly, they can eat away the base of the shingles causing severe damages to the foundation, leaving your roof to rot and you having to replace them.

The normal lifespan of a shingle roof is around 25 years, however, it might not last that long with the invasion of these organisms, as they can reduce its life by as many as 10-15 years..

4. Maximized Home Value

This is particularly important to people who might want to sell their home. Occasionally, a roof accounts for a large percentage of a home’s curb appeal (almost 40%). Therefore, a roof covered with algae or dirty with black stains says bad things about the overall care of the property and makes potential buyers suspicious. This can be easily avoided by having the roof power washed and getting rid of the dirt and mold before putting your home in the market.
