A modern roof should last 30+ years, yet an infected roof without maintenance will cause enough shingle damage to require early replacement. Typical loss of roof integrity due to late Stage 2 Infection is 30% (i.e. If your "30 year" roof was $10k that's a $3,000 loss on your investment). Please contact us and we will provide you with a detailed packet explaining How and Why your roof is being deteriorated by the infection.
STAGE ONE: No damage, requires only Preventative Treatment or Light Cleaning. Roof will typically meet or exceed its warrantied lifetime.
STAGE TWO: Damage begins. Excessive granular loss and heat retention. Treatment ranges from Medium to Heavy Cleaning. Roof can be saved.
STAGE THREE: Roof is severely damaged and will literally crumble under severe weather. Roof can be cleaned for aesthetic purposes but will still need to be replaced.
