Low Slope Roof Corrugate

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.

These panels generally come with a painted mill finish or a clear acrylic finish. Low slope metal roofing materials include perimeter edge flashing soffit panels drainage and es 1 rated edge systems from sheet metal supply. For a low slope residential roof there are two main options. Minimum metal roof slope depends on the roof profile building design climate and site location.

Corrugated roofing is a great material on traditional pitched roofs but it has severe limitations when the pitch gets below 5 degrees. Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems. This top layer normally is tar over which the gravel is laid. Built up roofing is the most popular roofing material used on low sloped roofs.

Low slope metal roofs require less material which reduces the overall load on the building s structure. The corrugated metal roof minimum slope is 5 degrees. Definition of low slope roofing a low slope roof is one that slopes 2 in 12 to 4 in 12 of run. Low slope structural roofing generally used on roof pitches ranging from 12 to 3 12 consists of interlocking panels commonly called standing seam roofing that run vertically along the roof surface.

Made of several layers of bitumen surfaces built up roofing is finished by applying an aggregate layer or coating as the top layer. That is why all roofing manufacturers recommend the 5 degree pitch as the minimum slope and they will not provide any guarantees if it is installed flatter than this. Michael bodmann getty images. It s constructed of a durable reinforcing mat of non woven glass fibers that have been coated and permeated to a thickness of approximately 2 0 mm.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. The membrane will outlast the shingles and seal around all nail penetrations. Because low slope roofs also drain water more slowly than moderate or steep sloped roofs systems such as slate or asphalt shingles that rely on mechanical drainage for successful performance are not used. 1 cover the entire surface with a self adhesive flashing membrane such as grace ice water shield there are many equivalent products.

Corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. Then apply standard asphalt shingles over the membrane.
