A fire resistant roofing material includes a core sheet and a sheet of conductive material having a thermal conductivity greater than about 25 W/m-K. The sheet of conductive material is coextensively bonded with the core sheet, and coated with a polymer-modified bituminous material having fire-resistant properties.

A method for sealing a substrate including steps: i) providing a membrane sheet including a barrier layer and a plurality of spaced-apart strips on a lower major surface of the barrier layer, ii) providing a fresh cementitious adhesive composition, iii) applying the fresh cementitious adhesive composition to a surface of the substrate to form a wet adhesive layer, iv) covering at least a portion of the wet adhesive layer with the membrane sheet such that at least a portion of the outer surfaces of the strips are directly contacted with the wet adhesive layer, and v) letting the wet adhesive layer to harden to effect adhesive bonding between the membrane sheet and the substrate.
