Install Metal Roofing Low Pitch Roof
Attach drip edge along the edge of the roof with roofing cement.
Install metal roofing low pitch roof. Now we re going to look at something that does happen quite often. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. 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.
Lay the starter row of metal shingles at the drip edge and affix to the roof with metal roofing nails. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. Low slope metal roofs require less material which reduces the overall load on the building s structure. A seaming apparatus is simply rolled along the panels to crimp the panel seams together.
Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. The corrugated metal roof minimum slope is 5 degrees. 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. Learn more about the installation of pitch transition trim by watching the short video or reading the transcript below.
Most metal shingles will be attached to the roof using metal shingle. Available in 12 16 and 18 widths tite loc and tite loc plus panels can be produced in 22 and 24 gauge steel or 032 and 040 aluminum. You ll have a steeper part of your roof turning into a lower slope so there s a steeper pitch up top and a lower pitch on the bottom. Work up from the initial row starting at the lower corner in a diagonal pattern staggering the shingles to prevent gaps.
Some metal roofing used on low slope applications requires machine seaming during installation to ensure a watertight seal.
