The Asphalt Shingle Roof is widely used roof in Winston-Salem, Triad area. This type of roof is resistant to extreme weather conditions and add value to your home. Many homeowners choose this roof over other roofing options due to ease of installation and adaptability. Asphalt roofs are available in many more colors. To answer the question of our article, simple answer is anything below 4:12 is considered a low slope and 2:12 is traditionally considered the absolute minimum acceptable roof slope for asphalt shingles. To help you to understand it better let’s take a look at Ashplant Shingle Roof and other consideration in details below.

What is the Minimum  Slope Requirement where Shingle can be Installed?

Asphalt shingle roofs have minimum slope of 2:12. The Roof pitch between 2:12 and 4:12 is considered low pitch, which means that shingles can be installed on the roof slope.

Why is 2:12 the Minimum?

Consider the roof slope requirement. For example, if the slope is very low, water, including snowmelt or rainwater, drains slowly, increasing the likelihood of lateral water movement between the shingles. Always confirm the specific slope requirement with the shingle manufactures, product installation instructions and local building code requirements. Roof manufactures recommend a roof slope of 2:12 to 4:12, although some shingles may have a minimum slope recommendation higher than 2:12. Furthermore a 4:12 slope is widely regarded as the lowest for standard shingle installations. Shingle roofing is not watertight, and minimum slope roof can get in between the laps. This indicates that 2:12 is the minimum.

If a roof slope rises by 4 Inches when measured 12 inches along the bottom of a horizontal roof truss, the roof slope is said to be 4:12, which means 4 inches of rise per 12 inches of run.

Precautions when installing shingle on low slope

Lower slopes make it harder for a shingle roof to shed water and this extra protection makes sure that if water gets below the shingles, it doesn’t result in a leak! Also, on lower slopes, wind driven rain water can be more of a concern and again, the extra protection helps to protect your building when weather threatens.

Do not reduce the exposure of the shingles to compensate for the low slope installation. Often, roofers may offer this as an option, but this practice is not recommended. Also, completely cover the deck with two layer of roof deck protection. Use only enough nails to hold the roof deck protection in place until covered by shingles. At eaves use GAF Leak Barrier. Where ice dams are not expected, 2 layers of Roof Deck Protection.
