Roof Waterproofing with Polyurea
Reliable roof waterproofing that prevents costly damage down the road. Duayen specializes in applying polyurea - the world's strongest waterproofing material - on flat, sloped and tile roofs, with genuine GRACO equipment and up to 10-year written warranty. Nationwide service.
Which Roofs Do We Seal?
Our team performs roof waterproofing for all building types - residential, shared, industrial and commercial:
Flat Roofs
Seamless waterproofing that withstands standing water and the Israeli sun - the most common solution for buildings and roof terraces.
Tile Roofs
Tile roof waterproofing with polyurea under or over the tiles, including sealing around openings and gutters - a solution that prevents leaks for years.
Sloped Roofs
Flexible application that bonds to any slope and angle, including metal, concrete and plaster roofs.
Industrial Roofs & Commercial Buildings
Roof waterproofing for factories, warehouses and commercial centers - resistant to loads, traffic and chemicals.
Why Polyurea for Your Roof?
Built for Israeli Weather
Withstands strong UV radiation, extreme heat, rain and moisture - without wearing out or peeling over the years.
Seamless Continuous Layer
Polyurea is sprayed as one continuous layer that wraps every corner, opening and protrusion - the weak points where leaks start disappear.
Flexibility That Prevents Cracks
The material stretches up to 400% and bridges existing cracks, even as the building moves or temperatures change.
Fast Work, Minimal Disruption
Dries in seconds - most roofs are ready within one to two days, without a long evacuation of your home or business.
What Is the Best Roof Waterproofing Material?
If you are comparing waterproofing materials for your roof, it helps to know the differences: tar and bituminous membranes are older methods that require joints and ongoing maintenance, and wear out relatively fast in the Israeli sun. Polyurea, by contrast, is sprayed as a seamless, flexible layer that dries in seconds, resists UV radiation and stays watertight for many years.
At Duayen we work exclusively with 100% original polyurea - not diluted, not imitation - because it is the material that truly holds up on your roof.
