Do asphalt shingles with the Scotchgard™ Algae Resistant Roofing System cost more than regular asphalt shingles?
Yes, but many experts and homeowners agree that it’s much less expensive to prevent algae growth from the outset. The price difference is minimal when one faces the accumulated cost of frequent roof cleanings. The extra cost associated with the Scotchgard™ System refers to the materials only, because the labor cost to install these shingles is the same as it is for regular shingles. Visit www.scotchgard.
