Have you noticed those unsightly black or green stains on your roof recently? If so, don't replace the roof! Renew your tile roof or shingle roof with a soft wash, low pressure cleaning by Walker Services!
It's worth noting that besides just being an eye sore, algae and mold hold moisture within the shingles that can cause premature aging, rotting, and will shorten the life of your roof by dislodging the granules that protect and give your shingles color. Also, the algae causes your roof to become less reflective and start absorbing and retaining heat which raises your utility bills and ultimately can lead to expensive repair or replacement issues.
