How is roof cleaning beneficial?

A 2,500 square foot roof, with architectural shingles on a residential home can cost $8,000.00 for installation and materials. If the service life expectancy is 30 years, then the amortized yearly cost of that roof is $266.00/year. If poorly maintained, the life expectancy is cut in half which means the annual cost is now doubled to $533.00.

Though there are many things homeowners can do to save energy around their home few things help like a clean roof. In fact, when compared to other items like:
  • Adjusting your thermostat up by 2 degrees from 76 to 78.
  • Lowering the thermostat setting on your hot water heater.
  • Shutting off lights when not in a room.
  • Washing your clothes in the cold setting.
Cleaning your roof can save more than all of these combined. In the end, you actually save money having your roof cleaned. Don’t believe me? The facts are in the figures

Let’s say you have a 2,500 square foot home. The roof square footage is actually 3,000 square feet. For demonstration purposes the cleaning will cost $600.00 and you have a $250.00 a month electric bill. Let’s assume that 5 months out of the year you run your A.C. Finally lets use a 20% post cleaning savings to be super conservative.
  • $250.00 Electric Bill (20%) = $50.00 Savings / Month
  • $50.00 Savings / Month (5 months) = $250.00 Savings / Year
  • Roof Stays Clean 3 Years…
  • $250.00 Savings / Year (3 Years) = $750.00 Total Savings
  • $750.00 Total Savings – $600.00 Roof Cleaning = $150.00 Profit.
Your roof, home and surroundings need to be safeguarded against the possible health issues that can come from mildew, algae, fungus and bacteria. Starting from your roof, many areas can be effected by these microbials. Every time it rains, every morning dew, the fungus on your roof drips down spores onto sidewalks, driveways, decks, walls and more. These spores then attach and grow new colonies. These colonies are then transported into your home by foot traffic, pets and by air itself.

Think of it like this, your roof is like a giant Petri Dish growing and cultivating fungal samples like a super lab. You can break much of this cycle by keeping your roof clean. Then focus on the other areas of the outside of the home. Decks, drives, walls all need to be cleaned. Remove any standing water. Discarded pots from plants hold water. Look everywhere to make sure that your home and surroundings are free from unneeded moisture and fungus.

The reason for discoloration

The streaks that are staining the surface are actually a bacteria called Gleocapsa Magma. This is the main culprit for most of the staining throughout the US. There are a few more culprits that also grow up on roofs making a mess of things. Roof top organisims like mildew and algae are unsightly but not as destructive as some of the more aggressive bacterias and fungus. Moss and Lichens also abound and are the final bad actors that show up after the party has been started by the fungal growths. These algae, molds, mildews, bacterias, lychens and mosses directly decompose and break down roofing materials.

Much of the organisms are there because of the warm, moist environment a roof creates, especially on the north and west sides of a roof. Micro organisms populate in an abundance growing so well that they begin to be noticeable to the human eye. Many roofing/building surfaces are made with materials that can be metabolized by the micro organisms. Shingles now contain limestone as a filler mixed into the aggregate of the shingle. Many of the algae, mildew and bacteria’s utilize this limestone as the base nutrient of their roof ecosystem and begin to feed on it.

The good news is that these stains / micro organisms can be safely removed. In fact, professional cleaning / sanitizing systems have been created to deal with this menace. Cleaning systems like soft wash agricultural style sprayers, chemicals and products give a professional the tools they need to safely remove the pests.

Though very little scientific study exists on what these algae, fungus and bacteria do to a roof, it is widely accepted by the experts in this field that these bacteria and algae do harm roofing systems. There is an abundance of photo documentation of surfaces left unchecked and exposed to these micro organisms that show significant degradation to the building materials.
