Frequently Asked Questions

Your questions about roof waterproofing for properties—answered.

The products and systems Danosa makes meet the highest industry standards: Miami-Dade County, Cool Roofing Council, American Society for Materials Testing, FM Global, and Underwriter Laboratories.

Yes. Danosa waterproofing membranes, materials, and systems come with a warranty. As long as a certified installer does the work. The specific period and terms may vary depending on the product. Please note that property owners may request a roofing certification to validate warranty claim eligibility.

Sure you can—as long as you choose the right waterproofing product. The engineering behind SBS-modified membranes works best for colder climates. Because it's elastic and adapts to sudden temperature changes and building movements. On the other side, APP-modified membranes excel at protecting roofs under intense hot weather conditions. Consult with Danosa's technical team on the materials you're buying if needed.
