Composite roofing or other surfacing board, method of making and using and roof made thereby

A composite board for use as a roofing or other surfacing material comprising a sandwich of

• (a) a core material layer having first, upper, and second, lower, opposite surfaces and being a solidified, previously molten bituminous material having filler components of recycled roofing products therein that include any of:
• (i) shingle particles containing fibrous material;
• and
• (ii) roll roofing particles containing fibrous material;
• and wherein any fibrous materials of the core material are comminuted particles of fibrous materials
• (b) a first layer of mat material with a lower surface adhered to the first, upper, surface of the core material layer;
• (c) a second layer of mat material with an upper surface thereof adhered to the second, lower, surface of the core material layer;
• (d) a layer of adhesive secured to a lower surface of said second layer of mat material;
• (e) a removable layer of release liner adhered to and covering said layer of adhesive of clause (d);
• and
• (f) wherein a said layer of material from clause (b) comprises a photovoltaic layer.

A method of making a composite board for use as a roofing material comprising the steps of:

• (a) providing a first layer of mat material;
• (b) then providing a non-solid molten core material layer on the first layer of mat material with a first surface of the core material layer disposed against the first layer of mat material, with the layer of core material being a bituminous material having filler components of recycled roofing products therein that include any of:
• (i) shingle particles containing fibrous material;
• and
• (ii) roll roofing particles containing fibrous material;
• and wherein any fibrous materials of the core material are comminuted particles of fibrous materials
• (c) thereafter applying a second layer of mat material onto a second surface of the core material layer;
• (d) applying a layer of adhesive to one of the first and second layers of mat material and securing the layer of adhesive thereto;
• and
• (e) applying a removable layer of release liner to said layer of adhesive and
• (f) applying a layer of photovoltaic material to the other of said first and second layers.
