Install Metal Roofing Low Pitch Roof

Some metal roofing used on low slope applications requires machine seaming during installation to ensure a watertight seal.

Install metal roofing low pitch roof.

Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. For example if your roof measures 10 feet 3 0 m x 10 feet 3 0 m and the slope of the roof is 12 12 giving a slope factor of 12x12 12x12 12 converts to 1 414 in decimal form you would multiply 10 x 10 x 1 414 to get the total of 141 square feet of roofing. Low slope metal roofs require less material which reduces the overall load on the building s structure. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. 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. Work up from the initial row starting at the lower corner in a diagonal pattern staggering the shingles to prevent gaps. Minimum pitch for corrugated metal roof corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch.

Lay the starter row of metal shingles at the drip edge and affix to the roof with metal roofing nails. A seaming apparatus is simply rolled along the panels to crimp the panel seams together. You can install roll roofing on your own but it goes more smoothly with a helper so grab a friend and get started. 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.

Attach drip edge along the edge of the roof with roofing cement. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. The corrugated metal roof minimum slope is 5 degrees. 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.

Most metal shingles will be attached to the roof using metal shingle.
