Established in 1976, All Under One Roof has the experience and expertise to get the job done right the first time. Our skilled professionals use only the finest tools and materials for your residential or commercial project. We guarantee our work and your satisfaction.

"Overall it went great. John was down quickly after I first contacted him. He came out in person to give me information and confirm the online measurements. Between meeting him, reading the reviews online, and the impeccable warranty I felt very comfortable choosing him (the price was in the middle of the other quotes I got). The whole process took 3 real long days. Obviously it is loud and disruptive while they are working... but you only need a new roof once. I would suggest not parking in your driveway as there are a lot of people and trucks. At the end they cleaned up very nicely. They are a legit roofing company so they pull permits. Overall I am quite please for the job, cost, time etc."

FAQs for roof sealant application projects in Dover, NH

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
