Roof Cleaning, Restoration & Preservation


Are you concerned with preserving the integrity of your roof? Do you want to extend the life of your roof, getting the most value out of it as possible? Our moderate, yet damp climate provides a host of challenges for northwest homeowners who desire to keep a healthy, safe and attractive looking roof.

DAPrDAN provides exceptional cleaning, restoration and preservation services for metal roofs, cedar shingle roofs, composite/asphalt roofs and ceramic tile roofs. Depending on the level of service you select, we can provide you with either a 1-year, or 3-year guarantee that your roof will be free of moss, lichen, algae, mold, fungus and harmful bacteria.


What your neighbor in Issaquah, WA says:

We have used DAPrDAN to clean and treat our roof and gutters on several occasions and have always been very pleased with the results. Our recent service was provided by two congenial and professional technicians who arrived on time, worked diligently, removed all fallen debris, and left our roof and landscaping around the house looking better than ever! DAPrDAN will even return in 6 weeks to check on the moss treatment. I highly recommend their services.
