Low Slope Corrugated Roof

At the upstream end of the corrugated iron roof sheeting the valleys are turned up to prevent.

Low slope corrugated roof.

For a low slope residential roof there are two main options. Then apply standard asphalt shingles over the membrane. Just like other metal roofs the minimum pitch for a corrugated metal roof largely depends on the profile of the roof. But the taller profiles like standing seam and pbr shown below can be installed on roofs with as low as 1 4 or 1 2 in 12 pitch.

These panels generally come with a painted mill finish or a clear acrylic finish. Corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. The corrugated metal roof minimum slope is 5 degrees. During heavy rain the valleys of the corrugations fill up to the height of the crest or even above that.

In most occasions a pitch of three in twelve is preferred but this should also take into consideration the manufacturer s recommendations as well the unique condition of the corrugated metal roof.

Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. Made of several layers of bitumen surfaces built up roofing is finished by applying an aggregate layer or coating as the top layer. There are two main reasons why corrugated roof sheeting and low pitches do not mix. There is only one category of metal roof systems used in low slope applications structural metal panel.

The membrane will outlast the shingles and seal around all nail penetrations. This top layer normally is tar over which the gravel is laid. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. Because of the shallow height of the undulating ridges of the 5v and corrugated profiles and the use of exposed metal fasteners to screw the metal to the roof deck they are limited to a slope that will shed rain quickly.

Built up roofing is the most popular roofing material used on low sloped roofs. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. 1 cover the entire surface with a self adhesive flashing membrane such as grace ice water shield there are many equivalent products.
