Tile Roof

Boral® Ply 40 is an SBS modified fiberglass reinforced underlayment/base sheet for tile, shingle, shake or as a waterproof base for torch down APP, SBS & BUR system. SBS modified asphalt minimizes wrinkling and buckling associated with non-modified membranes.

A self-adhering, modified asphalt underlayment that is easy to install and provides a slip-resistant surface that seals around nail penetrations, making it the preferred choice for tile roofs.

Citadel® Plus SBS modified asphalt core self-seals around nail or screw penetrations when mechanically fixing roofing. Seals to the roof deck providing additional security against potential leaks compared to mechanically fastened base sheets.
