In early 2025, our homeowner in in Broomall, Pennsylvania, contacted us with a persistent patio roof leak. After heavy rains and years of wear, water intrusion had become a regular issue, threatening the integrity of the roof structure and causing concern for the homeowner. Our team at BMG Exteriors was brought in to provide a long-term, effective solution that would protect the space for years to come.
Challenges
The primary concern was water penetration during storms, which had already begun affecting the ceiling underneath the patio roof. The surface had accumulated significant dirt and biological growth over time, which would hinder proper adhesion of any sealing materials. The homeowner also requested a solution that would be low-maintenance and come with a strong warranty for peace of mind.
Solution
Our team developed a three-step restoration and waterproofing plan:
Surface Preparation
We began by thoroughly power washing the entire patio roof, removing built-up debris, mold, mildew, and any loose material. This crucial first step ensured the roof would be clean and ready for coating, allowing for optimal adhesion of the primer and silicone layers.
Primer Application
Once dry, we applied a high-quality primer coat across the roof surface. This layer serves as a bonding agent between the roof and the top coatings, sealing any minor imperfections and enhancing the longevity of the final product.
Silicone Coating System
To complete the waterproofing process, we applied two coats of premium-grade silicone roof coating. This silicone material is UV-resistant, highly flexible, and impermeable to standing water—ideal for flat and low-slope patio roofs. The dual layers provide a thick, seamless membrane that eliminates existing leaks and prevents new ones from forming.
Results
The project was completed efficiently and on schedule. The homeowner now enjoys a fully sealed and leak-free patio roof, backed by a 10-year manufacturer’s warranty on the silicone coating. Thanks to the reflective white finish, the roof also benefits from improved energy efficiency by deflecting sunlight and reducing heat absorption.
Our client expressed high satisfaction with both the professionalism of our crew and the quality of the finished product. With the added assurance of a long-term warranty, the homeowner now has peace of mind knowing their patio is protected from the elements for the next decade.
