Asphalt rolled roofing will have plastic roof cement in the seams, while mod bit roofing will have melted tar squeezing out of the seams.

Can you paint modified bitumen roof?

Elastomeric acrylic coatings can smooth polymer-modified bitumen and mineral-surfaced cap sheets to turn their black surfaces white and extend roof-system life cycles while lowering energy costs. This is due to the fact that these coatings reflect sunlight, which lowers the temperature of the roof and the underlying building. This can result in significant energy savings, as well as prolong the life of the roof.

A modified bitumen roofing system is one of the most trusted roof systems because of its inherent thickness. A 2-ply mod-bit system with a granulated cap sheet is typically 240 MILS thick or more. On the other hand, a typical single-ply thermoplastic roof membrane is often 60 MILs12. This added thickness provides greater puncture and tear resistance and makes the mod-bit system more resistant to wind uplift.can you repair a modified bitumen roof_2
