Pitched Roof Construction Materials

Roof pitch area multipliers.

Pitched roof construction materials.

Roofing material is estimated by the square which is equal to 100 square feet. The smallest pitch of a roof is 0 5 12. The average roof is 3 000 square feet or around 30 squares. Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.

If you are going to use shingles build a pitched roof over the mobile home. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area. Otherwise the safest minimum pitch for rolled roofing is 2 inches of decline per 12 inches of horizontal direction 2 12 pitch. Traditional 3 tab shingles made with asphalt composite are the most popular type of shingle and are the most flexible in terms of adapting to many roof pitches.

Shingles can be fabricated from a wide range of materials such as asphalt least expensive to natural wood metal tiles and heavy slate most expensive. Rolled roofing material is often used on roofs that are low sloped. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. A 12 in 12 pitch is a steep 45 degree angle roof.

You should use rolled roofing on a flat roof over lap 1 2 the width of the rolled roofing. Shingle roofs typically have a life span of 15 30 years while membrane roofs usually last 5 15 years. The pitch of the roof is the rise over a 12 inch run. The roofing materials most often used for these pitches include asphalt composite shingles.

For example a 4 12 pitch roof that is 100 square feet. A mobile home roof should not be flat. The most common roofing materials used in the united states include shingles membrane roofing and ceramic tile all of which have different life spans. If your roof pitch declines up to 1 inch vertically for every 12 inches horizontally 1 12 pitch it is a good candidate for rolled roofing as long as you use the concealed nail method of fastening.

The dead air space between the metal roof and shingle roof will work as a barrier to dissipate heat. Pitched roofs are most often associated with asphalt shingles although standing seam roofs are becoming ever more popular on pitched roofs as well. See the image below for more explanation on rise run and pitch. A common choice for flat roofing material is epdm rubber as it is highly durable waterproof and can be made from recycled materials.

The basic ranges of pitch are not uniformly defined but range from flat which are not perfectly flat but sloped to. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
