the Roof Construction Manual is a comprehensive reference work on the construction of pitched roofs, containing over plans and photographs. Thirteen fundamental roof types and the relevant materials including thatch, wood, slate, tile, concrete, fibrous cement, bitumen, glass, metal, membranes, and synthetic materials are documented in. Covers the general principles of pitched roof design. It does not cover the design of hatches, chimney openings etc., or the additional support that is required for water tanks or other added loads. History. April edition, with minor corrections. Supersedes the December edition. First published , revised Subjects. It illustrates the application of principles based on thermal and moisture considerations that can be summarized as follows: An insulated roof system must be designed to prevent the entry of moisture into the assembly, from both inside and outside, or it must be capable of dealing with the moisture that enters during or after construction. Steep Slope Roof: A roof surface of at least 3 units vertical for every 12 units horizontal; a roof pitch of at least 25 degrees. Roof Covering: The top layer of material used to cover and protect the roof surface. (Shingles, Tile, Slate, Metal, etc.) Roof Underlayment: Base layer material installed above the sheathing but under the roof covering.

Pitched roof - Designing Buildings Wiki - Share your construction industry knowledge. A pitched roof is a roof that slopes downwards, typically in two parts at an angle from a central ridge, but sometimes in one part, from one edge to another. The ‘pitch’ of a roof is its vertical rise divided by its horizontal span and is a measure of its steepness. Covers the general principles of pitched roof design.

Roof coverings range from natural slates, clay and concrete tiles, through to metal sheet materials, membranes and green roofs. Functional requirements. The functional requirements of a roof are: Strength and stability.

The most commonly used types of pitched roof construction are the gable, the hip, the intersecting, and the shed (or lean-to). An example of each is shown in figure Gable A gable roof has a ridge at the center and slopes in two directions. It is the form most commonly used by the Navy. It is simple in design, economical to construct. Description. The pitch of a roof is its vertical 'rise' over its horizontal 'span'. However, most often a ratio of "pitch" (also fraction) is slang used for the (more useful) 'slope' (of rise over 'run') of just one side (half the span) of a dual pitched roof. This is the 'slope' of geometry, stairways and other construction disciplines, or the trigonometric arctangent function of its decimal.
