Roof coverings need love. For roof coverings, love means maintenance, such as clearing roof planes of debris or treating roofs on a semi-annual basis to prevent moss growth.

Love does not mean pressure washing a roof, however. Don’t believe me? Roofing experts will tell you the same thing.

Pressure washing can cut the life expectancy of a roof dramatically, and lead to mechanical damage—such as granular loss and exposed fiberglass underlayment at roof shingles. Exposed shingles with granular loss are vulnerable to reduced life expectancy. I discovered this very scenario during a recent inspection in Coupeville.
