Western Pacific Roofing Has Many Years of Experiences...

Installing most major built-up roofing products and are certified applicators with approval to offer manufacturer’s full system warranties. Conventional built-up roofing systems come in many variations with different types of finished surfaces. The term built-up refers to building the system together with a number of ply sheets. Typically, built-up roofs have multiple layers or plies within the system. The most common types begin with a base sheet adhered by mechanically fastening or adhering the base sheet to the deck, or over specified insulation, when high energy efficiency is desired, then followed by 2, 3, 4 or 5 layers of inner-ply sheets adhered together with hot applied asphalt. The finished surfacing can be gravel, rock, a mineral surfaced cap sheet or an applied top-surface coating.

The type of finished surface, such as the application of coatings (including Cool Roof Rating Council approved coatings), gravel, granules, etc., will help determine the life expectancy or longevity of the built-up system and protect the underlying plies from direct exposure to the sun.
