Algae, mold, and dirt sitting on your roof can compromise the structural integrity of the shingles, weakening them and becoming a less durable layer of defense for your home. One easy way to maximize the lifespan of your shingles is to clean your roof every couple of years after the algae-resistant coating wears off.
When should you consider cleaning your roof?
The majority of quality shingles have an algae-resistant protectant coating over the shingles. Still, over time and exposure to the elements this layer wears off and your roof can begin to allow algae and mold to stick to your roof and spread if left unattended. If you see any signs of your shingles darkening in color and appearance, it may be time to consider cleaning your roof.
Why should you clean your roof?
The roof is your home’s first and last layer of defense from the elements and a well-built, constructed and maintained roof can keep your family and belongings safe for years to come. If algae growth spreads over the surface of your roof, this can weaken your shingles and over time lead to accelerated aging of your roof.
How can I clean my roof?
The safest for your roof and most effective option is a soft roof wash. A mixture of Sodium Hydrochloride, a dilution agent, and surfactant is sprayed onto the surface of your roof. The mixture will begin to work its magic, killing all of the algae, removing dirt, and restoring your shingle to its original color. The best option is to use a soft wash machine, but the same result can be achieved with a hand pump and a little hard work.
Overall, keeping your roof clean will maximize the lifespan of your shingles, remove dirt and algae that can weaken them, and not to mention increasing your home’s curb appeal.
