Weathershield

Weathershield is a water-based roof treatment designed to extend the life of your roof by 30% to 50%. Environmentally compatible, non-flammable, and nearly odorless, Weathershield is applied after gently cleaning debris from the roof using air or light water blowoff. Following this, necessary repairs are made, including minor shake or ridge cap replacements. The treatment is applied on dry days to ensure deep penetration, and once the water evaporates, safe chemicals are left behind to protect your roof. Weathershield transforms with rain, sun, and temperature changes, gradually killing moss and lichens and turning the roof a light silvery grey. Roofs previously treated with colorants or stains may not experience a shift to the natural gray color.

This natural cleaning process works with every rainfall, helping to rinse away moss and fungi over time, with full cleaning results typically appearing within six months and lasting up to five years. By altering the pH in the wood to a more alkaline state, Weathershield also prevents moss, fungi, and lichens from regrowing. The treatment includes a 5-year no-moss warranty, offering reliable and long-lasting protection for homeowners in Mill Creek. Alpine Roof Care proudly provides Weathershield services to help protect and enhance roofs across the area.
