Modified Bitumen

Modified bitumen roofing installation and restoration for commercial flat and low-slope roofs. Excellent durability and puncture resistance.

About Modified Bitumen

Modified bitumen roofing combines the proven performance of traditional asphalt-based systems with modern polymer modifiers (SBS or APP) that greatly improve flexibility, durability, and resistance to temperature extremes. Restco Roofing installs and restores modified bitumen systems for commercial and industrial applications. For aging modified bitumen roofs showing cracking, blistering, or seam separation, our restoration approach applies seamless silicone or elastomeric coatings that re-waterproof the surface without requiring a costly tearoff. Restoration qualifies as a 100% maintenance expense for tax purposes.
