"We recently had our home siding replaced by J.W. Tull, and the entire experience was excellent from start to finish. Their price was very competitive, and the quality of their work was outstanding. Joel, our project consultant, was incredibly helpful in guiding us through the design and product selection process. He helped us choose a combination of CertainTeed siding with beautiful accents in shakers, board and batten, and stonework — and the end result exceeded our expectations. Joe, our project manager, was meticulous and detail-oriented. He kept us informed throughout the entire project and was always easy to reach with any questions. We couldn’t be happier with how everything turned out — especially the stonework, which looks absolutely stunning. The craftsmanship and attention to detail really show. We highly recommend J.W. Tull to anyone considering new siding!"

"Alex and his crew did a beautiful job on our existing deck floor. They were professional and courteous. I would have given them a Five Star Rating, but my contract also included installing one window shutter which had to be special ordered. Our deck floor was completed and the final payment was paid before the window shutter arrived. I called Southside Construction several times for someone to come back to hang my window shutter and complete the contract, but to no avail. "

FAQs for roof sealant application projects in Dover, DE

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.
