Choosing the best low slope roof materials often comes down to weighing the pros and cons based on your home and your needs.

Can I use shingles on a low pitch roof?

Most shingles may be applied on roof slopes of 2:12 to 4:12 (a “low slope” roof), providing that the shingles are adequately sealed against wind lift, and special procedures are followed. In many building codes, allowances are made to permit applications of asphalt shingles to low sloped roofs.

What shingles are best for a low slope roof?

The slope or pitch of a roof dictates the type of shingles you should install. For a low-slope roof such as 4:12 to 2:12, three-tap shingles are preferable. Low-slope roofs are more susceptible to ice and water problems such as ice dams, so better flow properties are important to consider for installation.

What is the lowest pitch a roof can have?

The smallest pitch of a roof is 1/4:12, which translates to 1/4 inch rise to 12 inches of run. Such a small pitch can only work with built-up roofing or specialized synthetic roofing. Covered porches that are near trees or in areas with heavy rains should not be covered with a low-slope roof.

How do you cover a low slope roof?

Modern low-slope roof or flat roofs tend to use a continuous membrane covering which can better resist pools of standing water. These membranes are applied as continuous sheets, bonded together with heat-welding or adhesives. A more expensive low-slope or flat roof option include sealed metal roofs using copper or tin.

Are metal roofs good for low pitch roofs?
