Expert Verdict — Reviewed by the SuperArbor Pro Desk
SBS modified bitumen underlayments like Layfast TU-35 are chosen where a tougher, more pliable deck membrane is wanted under tile or other coverings. Plan laps and fastening per MB Technology's installation instructions, and size rolls against the roof area plus lap allowances.
Underlayment surfaces can be slippery, especially when wet or dusty; wear slip-resistant footwear and use fall protection on the roof.
