Sloped Metal Roofing

Static water pressure is then applied to the outside face of the roof panel.

Sloped metal roofing.

Low slope metal roofs require less material which reduces the overall load on the building s structure. 3 12 1 2 12 and 1 4 12. Concrete clay roof tiles. These new roofs can be either low sloped less than 2 12 functional roofs or high pitched greater than 2 12 architectural roofs depending on the expectations of the building owner.

If you have a low slope application 3 12 or less is the industry standard it is important that you choose a mechanical system that is double locked. For example if the vertical height was 6 inches your slope would be 6 12 or 6 12 or 0 5 expressed as a decimal. The use of metal retrofit roofs allows the flat roofed buildings to undergo a transformation into a sloped roof building. Low slope metal roof systems are tested to astm e2140 standards a water penetration test evaluating the resistance of roof panels vertical seams.

Roof pitch slope for reference standing seam metal roofing is not one size fits all. During this test the roof panel system is completely submerged under six inches of water for approximately six hours. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Slope is calculated as rise over run.

Metal roof slope is expressed by a ratio indicating the roof pitch which notes the vertical rise of the roof in inches for every 12 inches the roof runs horizontally in other words dividing the vertical rise and its horizontal span. When looking at metal roofing panel you will need to. The minimum roof slope for metal roof panels depend on 3 different scenarios. Most buildings with metal roofing system are using corrugated roofing type.

Cedar shakes shingles. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. Typically low slope metal roof systems vary in weight from 40 to 135 pounds per 100 square feet making them among the lightest roofing products and the easiest to install. It is indeed the metal roof profile that is most used around the world which can be.

A lightweight roofing system also places fewer demands on a building s structural support system an important consideration in earthquake prone areas. Metal roofing is a unique trend in roofing and this guide will walk you through the steps including how to install metal roofing over shingles. The corrugated metal roof minimum slope is 5 degrees. Lapped nonsoldered seam metal roofs with applied lap.

It is the recommended slope as there is no guarantee if you opt for flatter pitch than this.
