We specialize in a variety of manufactures modified bitumen systems. We agree that the modified system is one of the more durable flat roof systems that stand to a test of time as well as excess wear and tear and normal elements caused by nature.

If your modified system is installed correctly, you should have years of protection with of course proper coatings and maintenance. We provide a commercial maintenance program to help insure each flat roof system last beyond its life cycle costs. Modified Bitumen systems come in a variety of colors in some locations of the USA. Most common color of Modified bitumen in the APP 180 White Granular, thus adding a solar reflective rating.

Some Modified systems are installed over a tapered insulation, standard insulation slopes are 1/4 or 1/8 pending on the structural needs for draining. In Dallas, we are seeing alot of slope roof structured with 1/2 plywood vs insulation which does not give you an r-rating. To us this is not correct installations but seems to be a sub-standard in the Dallas Metro Plex

Modified systems are either heat applied, hot mopped applied or even cold process

The most commonly used process for adhering a modified system is heat applied.

Insure all flashings are primered prior to your modified bitumen roof system installation
