Questions and Answers
How does spray foam insulation help with San Bernardino's roofing issues like moss and flashing leaks?
Spray foam creates a seamless, airtight seal on your roof deck, which directly addresses local problems. For moss, it eliminates the moisture and organic material that moss needs to grow by sealing out water. For flashing failures, the foam adheres tightly around vents, chimneys, and edges, preventing water intrusion at these common weak points. This proactive approach protects your San Bernardino home from the moisture damage that often leads to costly repairs.
What should I expect during a reroofing project with your team?
Our process begins with a thorough inspection to assess the condition of your existing roof. We then provide a clear plan and timeline. Our skilled crews, often trained by David himself, handle the removal of old materials and installation of the new roof with precision. We use quality materials and proper techniques, like secure flashing installation, to ensure longevity. Throughout the project, we prioritize cleanliness, safety, and clear communication, keeping your property protected and you informed every step of the way.
Why is your hands-on, family background important for my insulation job?
David Lenaker learned the trade directly from his father, an industry expert, and still trains crews on-site. This means the knowledge applied to your project isn't just from a manual—it's practical, field-tested experience passed down through generations. When you work with us, you benefit from that depth of understanding. We know how materials perform over time and how to tackle complex situations, ensuring your insulation is installed correctly for maximum efficiency and durability in your home.
