Yes, many roofs require additional repair. In these cases, we install Spray Polyurethane Foam (SPF) “CRICKETS” to direct water to specific scuppers to facilitate proper drainage, level filled ponding areas and apply SPF to the base flashing, penetrations, roof-to-wall transitions, etc. (typical leak sources)
Virtually FOREVER! Silicone is made from the same raw material as glass (Silica) and is a UV stable product meaning that it does not degrade with exposure to the sun and elements. That’s why you don’t have to replace the glass in your car and home every ten or fifteen years. This UV stable characteristic translates into a supremely durable, long-term Waterproof Roof Coating System AND it can simply be cleaned and re-coated INDEFINITELY. Never Re-Roof Again! Silicone is the only product that we see performing long-term in the field.
