Frequently Asked Questions

Your questions about roof waterproofing for properties—answered.

Consider your building's roof type, climate, and budget. Modified membranes last longer than liquid-applied coatings. The latter is less expensive, though. Consult with a roofer for tailored recommendations.

Waterproofing membranes differ in material, thickness, flexibility, application, and lifespan. For example, SBS-modified membranes perform better in cold climates than APP-modified membranes.

It depends on the roof size, membrane type, and installation complexity. Costs may range from $3-$10 per square foot on average. For an accurate estimate, the best way to go is to get in touch with a certified roofer.

DIY installation without prior training is possible with self-adhesive and liquid-applied waterproofing membranes. Still, it requires careful attention to instructions. For other types of membrane systems, you'd need training and tools. So a qualified installer will guarantee the work meets warranty conditions.

The roof waterproofing installation consists of properly cleaning and preparing the surface, then applying the membrane, and sealing it. Weather conditions, roof size, and project complexity may affect the timeline. But typical jobs take 2-3 days. It's recommended to request an inspection by Danosa's technical service team.

There's minimal visual impact. We design waterproofing membranes to either blend in with the existing structure or remain hidden. If the aesthetic is a concern, Danosa has color options available.

Properly installed, a waterproofing membrane system lasts no less than 8 years and up to 30+ years. Regular roof inspections once a year can catch issues early and extend the membrane's lifespan.
