Low slope metal roof underlayment.

Asphalt saturated felt along the eaves and lap succeeding courses by 19 inches as shown in figure 2 3. The underlayment can make it through the summer heat winter snow and spring rain on a low slope roof without anything covering it. With the slip resistant surface of synthetic metal roofing underlayment workers have a safer work environment as they can walk the slopes easily knowing that they have a firm grip on the surface. Also if you live in a climate such as the up in michigan and routinely get over a foot of snow standing on the roof you may want to consider it.

Hence attention should be paid to the roof slope and its geometrical shape before investing. It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too. Once the high temperature ice and water shield has been laid down you can now add the second underlayment layer. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. Lower slopes for low slope standing seam metal roof applications strictly peel and stick underlayment is a better choice. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. Low slope metal roofs require less material which reduces the overall load on the building s structure.

Guide to roofing underlayment installation on low slope roofs with asphalt shingles asphalt shingles can be used on roofs with a slope of 2 12 to 4 12 if double coverage underlayment is used. And this synthetic roof underlayment becomes famous due to its quality easy installation process and affordability. If the roof slope is below 3 12 pitch see our previous post on how to determine a roof s pitch the entire roof should be covered but only if the roof is conventionally vented cold roof construction. Recyclability smooth finish fire resistant.

Some shingle manufacturers require ice and water shield on very low sloped decks between 2 12 and 4 12. These advantages and disadvantages do not apply to granulated synthetic underlayment as it is not to be used directly under metal roofing. Set your store to see local availability. Minimum metal roof slope depends on the roof profile building design climate and site location.
