GAF StainGuard Plus™ for Algae Protection

Blue-green algae, also known as gloeocapsa magma, affects more than 80% of roofing systems in the country. It leaves dark black stains wherever it grows and makes millions of perfectly good roofs look old way before their time. 

As a GAF Master Elite® roofing contractor, Thompson Roofing and Construction is no stranger to this unsightly growth. Gloeocapsa magma may be blue-green in color, but it is surrounded by a dark brownish-black shell that protects it against the sun’s rays. Over time, these dark shells cause the telltale streaking on the roof.

Gutter Accessories: Features of Downspout Diverters

A well-designed roofing system keeps water from entering your home and channels rainwater and snowmelt to the roof’s edge. From there, a quality gutter system finishes the job by safely transporting the water down and away from vulnerable areas of your property.

Without gutters, water spilling off the roof will drip down unhindered and cause damage to siding, windows, masonry and the foundation of your home. There’s also the risk of ice dams and icicles forming, which is detrimental to the structural integrity of your roof.
