Have you noticed black streaks on your home? Or on someone else’s home?

If you haven’t I am sure you will pay closer attention now. Once you become aware of this common problem on everyday homes, you will be more likely to notice it right away.

Now to the meat and potatoes….

What is eating your roof? Those black streak are the start of your concern. That my friends is algae and it is FEEDING on the limestone in your shingles. The algae and bacteria are feeding, growing and spreading on your roof. Eventually if left untreated for too long, you end up with a heavy moss growth and lichen growth. This can cause serious damage to your roof and reduce the life of it. This wearing can cost you thousands of dollars, as you will have to replace it sooner.

Most people just think the black streaks are ageing of the shingles but this is not the case at all. Unknown to you, its causing your home to look dirty, taking away the life of your roof and impacting your health! Those mold spores and bacteria spread and go airborne. If left to spread, it will eventually move into your home through the attic and go airborne inside and outside your home. Now you are at risk of breathing contaminants that can effect your health.

You may be asking why does it happen on my roof?

It is a simple explanation…

Moss is a simple plant that grows vertically and lacks the common conventional roots, stems and leaves like other plant life. The growth of mold is limited to moist locations where the sunlight is non-existent or infrequent.

So roof shingles are the perfect place for moss to thrive. Why is this?

  • It receives the most rainfall
  • Has higher level of humidity
  • lack of direct sunlight
  • accumulation of leaves and other organic debris to aid in its growth.

You will notice that many homes have black streaks on one side or the other. This is because the moss and algae grow on the side with the least amount of light and has the best conditions to live.

Now there is a simple fix and a much more cost-effective option.

Find a company, such as Hogwash, that is certified, insured, trained, knowledgeable and has the proper equipment to come out to clean your home.

Cleaning the algae before it gets to the next stage will save you tons of money and make your home look good again.
