Long Life

The roof is the part of your building most exposed to climatic extremes. Wind, rain and roof surface temperatures ranging from 90°C in the summer to -5°C during winter nights in the deserts.

Fortunately, your DERBIGUM roof has the longest in-place performance of any APP Modified Bitumen roof available in the market today. DERBIGUM has traditionally doubled the lifespan of standard roofing materials.

DERBIGUM and DERBIBRITE offer the option of a direct recover rather than a complete tear-off. This Recover Program eliminates the cost of new insulation and man hours which will lower the Life Cycle Costs of the system. With this program it is possible to have up to 60-years of guaranteed waterproofing. No tear-off also means eliminating the waste sent to the overburdeoned landfills.
