PREPARATION FOR RE-ROOFING

SECTION 075113.11 - BUILT-UP ASPHALT ROOFING, HOT-APPLIED

This Tremco MasterSpec-based section specifies Tremco THERMastic hot-applied built-up asphalt and hybrid built-up roof (BUR) systems, consisting of multiple plies set in hot asphalt adhesive, with roofing accessories including membrane flashings, substrate board, vapor/air barrier, insulation, cover board, fasteners, and granular, aggregate or smooth-coating surfaces.

The companion Sections 076200 "Sheet Metal Flashing and Trim", 077100 "Roofing Specialties", and 077129 "Manufactured Roof Expansion Joints" specify the low-slope metal flashings and custom or manufactured roof edge, copings and certain roof drainage items that together with the work of this section form the total roof system. Warranty requirements for this Section cross-reference these sections.

Roofing Installer's Warranty Form is now Section 070101.01 MEMBRANE ROOFING INSTALLER'S WARRANTY. Be sure to include this document in your project when required.
