Signs Your Roof Needs Treatment:
Any Asphalt Shingle Roof That's Over 10 Years Old
Over the last 20 years, shingle manufacturers have reduced the amount of asphalt in shingles by as much as 40%. As a result, a "30 Year Roof" is now failing in as little as 10 years in the Mid-Atlantic climate. Even if you don't have visible signs yet, Roof Renew will reverse the deterioration of your roof, saving you thousands of dollars over the long term.
Algae Stains
Black algae stains are prevalent across Virginia, but most homeowners don't realize those streaks are actually a sign of a failing roof. The reduction of asphalt content in new shingles means the oils dry out much faster than they used to and that is what allows the algae roots to take hold. Algae roots are very destructive to the shingles, but cleaning alone won't solve the problem. Roof Renew re-saturates the shingle with bio-oils that choke off the root systems of the algae and prevent re-growth.
Granule Loss
Granules are the "rock" coating that protects shingles from the elements. As petro-chemical oils evaporate, shingles lose adhesion, become dry and brittle, and granules start to shed, often ending up in the gutter. Roof Renew penetrates the shingle, reactivating granular adhesion, and holding the critical protective granules in place.
Brittle or Cracked Shingles
The ability to expand and contract in rapidly changing temperatures is vital to the performance of shingles. Evaporation of the petro-chemical oils results in the loss of flexibility, leading to potential cracking, and even leaks. We'll caulk and seal minor cracks before applying Roof Renew, restoring flexibility.
Wind-Damaged Shingles
Evaporation of petro-chemical oils means the adhesive strips that hold shingles together lose their stickiness. That allows the shingle tabs to separate in a storm, causing damage and dramatically increasing the potential for leaks. Roof Renew re-activates the adhesive strips so the shingle stays in place during heavy winds.
A Roof Nearing the End of Its Service Life
Until now, there has been no alternative to roof replacement that could reverse the aging process of your shingle roof and extend its life. Roof Renew can extend the life of your asphalt shingle roof by 5-15 years, for up to 80% less than the cost of replacement. Before you replace that aging roof, contact us to find out if Roof Renew can save it.
