After Thomson Roof Treatment has removed the moss, lichen, mold and mildew from your roof and cleared the gutters so they flow properly, each home receives an individually determined moss-free guarantee, depending on the amount of trees hanging near your roof, and other criteria that would increase the return of moss growth. We guarantee that after the initial moss removal job is complete, the roof will stay clean of moss, black mildew, mold, or lichen for 12 to 24 months. If there are any concerns, we will return to make sure that you are satisfied, at no cost to yourself.

Moss Prevention Program
Roofs must be re-treated promptly at the end of the warranty period to avoid allowing moss to re-root and grow.
Although it may be convenient or seem financially prudent to delay re-treatment, we have found that the monthly cost to maintain your roof remains constant, regardless of when re-treatment is done. There may be an additional charge if a re-treatment order is made after the warranty period is up and prep is needed due to moss regrowth.
