Algae Control that Prevents Roof Damage from Your Battle Creek Roofing Contractor

Algae themselves don’t actually cause physical damage to a roof’s surface. They just sit there and alter the roof appearance over time, causing black streaks and stains that make a roof look worn and poorly maintained. If the environment is favorable for algae to grow however, other unpleasant headaches related to your roof may not be far away – such as the growth of roof moss.

On a roof surface, the exposure to daily sunlight, regardless of temperature helps the roof remain dry with moisture evaporating regularly. When algae lays on a shingle roof surface they contain small amounts of moisture. They sometimes grow more easily on a northern roof exposure, or other places where sunlight is blocked by shade or overhangs. The problem with this is that with prolonged moisture and blowing debris or dust, it now becomes easy for moss to attach itself to the algae and to the roof.

While moss itself also does not damage the roof materials, if left unattended, moss will begin to provide an environment that holds in moisture. When the moisture is secured in a concentrated area of the roof surface over a prolonged period, damages requiring expensive repairs can result. If algae can be prevented the odds of moss growing on the roof are often greatly reduced, if not eliminated. While some roofers place copper strips or copper flashing on a northern exposure so rain will wash the copper down (since copper kills algae) there are now more elegant solutions that provide more comprehensive protection.

For several years, asphalt shingles manufactured with copper roofing granules designed to offer algae protection, have been on the market. Most of them offer a 5 to 10-year guarantee against algae growth. Sherriff-Goslin, your Battle Creek roofing contractor, offers something even more compelling for homeowners who don’t want to worry about algae and it’s potential to attract moss – Scotchgard™ Protector. With Scotchgard™, there is simply no greater algae resistance, and we incorporate regular independent third-party laboratory testing to validate even spread of copper granules, ensuring maximum algae resistance is built into every shingle.
