Iko roof fast low slope roofing components are engineered and manufactured to meet those particular challenges.
Low slope residential metal roofing.
Corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch.
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.
Self adhesive flashing membrane under the shingles prevents leakage on low slope roofs.
Low slope metal roof systems are tested to astm e2140 standards a water penetration test evaluating the resistance of roof panels vertical seams.
Then apply standard asphalt shingles over the membrane.
A lightweight roofing system also places fewer demands on a building s structural support system an important consideration in earthquake prone areas.
Minimum metal roof slope depends on the roof profile building design climate and site location.
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.
Minimum pitch for corrugated metal roof.
Low slope and steep slope roofing systems have different industry standard testing requirements.
Low slope metal roofs require less material which reduces the overall load on the building s structure.
Flintlastic sa products feature easy and clean application and also have granulated surfaces with colors that coordinate with certainteed shingles providing the homeowner with a complete and coordinated solution for roof designs that transition from steep to low slope.
For the smaller residential low slope roofing applications such as garage and porch transitions certainteed offers an excellent solution in our flintlastic sa self adhering sbs modified bitumen roofing system.

Low slope roofs present special challenges in terms of preventing unique types of damage.
It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too.
Most structural metal panel roof systems are designed to resist the passage of water at laps and other joints as sealant or anti capillary designs can be used in the seams.
Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics.
Roof fast 95 base iko roof fast 95 base is a self adhesive product that can easily be cold applied on low slope roofs.
The corrugated metal roof minimum slope is 5 degrees.
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.
