Algae Resistance

Algae growth may cause brown to black streaks on roofs but this discoloration does not impact the service life of the shingles. Algae species are transported through the air and growth occurs to varying degrees in all regions of the country; especially those subjected to warm, humid conditions. Algae should not be mistaken for fungus growth, soot, dirt, or moss. Almost all types of roofing systems are susceptible to algae discoloration. For full details of coverage, refer to the actual warranty for details, limitations, and requirements.

ENERGY STAR® Rated Shingles

Similar to the energy-efficient appliances in your home, roofing products can provide heating and cooling saving qualities. Our shingles can help reduce your heating and cooling bills. Certain shingles reflect solar energy, decreasing the amount of heat transferred to a home’s interior — and the amount of air conditioning needed to keep it comfortable. Actual savings will vary, based on geographic location and individual building characteristics.
