Roof coating is a service that we offer for a great price especially when added in to exterior quotes as a package deal. We pressure wash the majority of our roofs with our gas pressure washer. We then coat with a 10 year product or better. In Arizona, roofs need to be recoated at least every 5 years. Even if you think it was previously done properly, have us check it after 4 to 5 years from the last time of service. Warranties are available upon request. This is a great way to feel assured your full exterior is completely protected from the time we finish.
