Sloped roof construction. A flat roof has a slope of 2 in 12 or less. Modern roofs take advantage of the flexibility of metal materials creating one large curved structure. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. A roof slope of 7 12 is also good and can provide the additional benefit of helping minimize the effects of wind driven rain.

This roof pitch calculator or roof slope calculator is a simple easy to understand tool to use when you need to perform construction work in your home. If there are gutters installed on the eaves the eave flashing should be installed to overhang the lip of the gutter by about 1 2 inch. There are two main categories of roofing.

Amongst many decisions one has to make when designing a metal building determining metal roof minimum slope is one of them.

A hybrid of a gable and a hipped roof. N s or e w for a gable roof. A low slope roof is anywhere from 2 in 12 to 4 in 12. A hipped roof is sloped in two pairs of directions e g.

Roof pitch is the degree of building s roof slope. However from the wind uplift mitigation perspective a 7 12 roof slope can be considered as a two story building due to the higher overall steepness and profile of the roof. Place corner pieces where panels will meet bends at the edge of the roofing. It determines how many inches the roof should rise for every 12 inches expanding on the horizontal side.

A type of japanese roof construction. Use 1 1 4 inch nails to cover the outline of the roof with strips of metal eave flashing also called edging. Roof covering materials provide weather protection and chapter 9 regulates the minimum required slope for each type of roof covering material since part of the performance of a roof covering material is based on the slope of the roof surface. To use this you must take the required measurements so you can input them in the required fields.

Roof pitches with lower angles such as 1 12 up to 3 12 are found in more urban contemporary style houses and in industrial buildings and shacks.
