Roof Soft-Wash Questions — Answered

A: Not without proof of roofing degradation or damage according to the State of Connecticut

By law, insurers have to give you at least 60 days' notice and spell out the specific reason(s) for non-renewal. Vague phrases aren't acceptable. Aerial images that show only cosmetic concerns can't be the sole basis, and CT Insurance Department (CID) has said this practice "will not be tolerated." Insurers need evidence of material damage or degradation that increases the risk of loss.

Below is a letter from the State of Connecticut on the subject matter.

Soft washing is the preferred method for roof cleaning. It uses a low-pressure application of cleaning soaps to kill mold, algae, moss, and lichen without damaging your shingles — and our method then lets natural rainfall rinse the dead growth away over time.

Power washing is too aggressive: high pressure strips granules off shingles and can void your manufacturer's warranty. Soft washing cleans without causing damage — that's why it's the right call for your roof.

A: Depending on the amount and strength of rain storms after treatment, It may take several weeks, to several months for all of the moss and lichen to rinse off of the roof shingles.

On Day of Wash upon completion of spray treatment you will notice all black streaking on the roof dissipating, and all lichen and moss will change colors from the shades of green, to more of a pale color that will turn more of a brown color as it dries up and will naturally rinse off.
