Roofing with Shingles ( laminated roofing) Organic-based asphalt shingles are manufactured with a base ( also termed mat or substrate) made of various cellulose fibres such as recycled waste paper and wood fibres. This organic base is then saturated with specially formulated asphalt coating and surfaced with weather-resistant mineral granules. Shingles are made of various materials such as wood, slate, flagstone, fibre cement, metal plastic, and composite material such as asphalt shingles. Roof Shingles are commonly used in the United States and Europe.

A roof truss takes a framework over a building span. It is the kind of support based on which roof can be attached. To ensure sturdiness and strength in roofs, trusses should be engineered carefully, pursuant to the house specifications. A properly executed rood truss has the capacity to support a rood against propulsions of rain, wind, or any significant tensions.
