Low-Slope Vs. Steep-Slope Roofing
When is a roof low-slope and when is it steep-slope? The magic number is less than 2:12 pitch. Any roof steeper than 2:12 is considered a steep-slope roof. If the roof on your project specifies a slope of less than 2:12 pitch, you’re dealing with low-slope roofing. South Florida has a good mix of low-slope roofing and steep sloped roofing – let’s take a look at some of the key advantages and disadvantages of these types of roofs.
Advantages Of Low-Slope Roofing
The costs vary for both applications, depending on the materials. A shingle roof on a steep sloped roof would cost less than most flat roofs, but a tile roof on steep slope would be a bit more.
It’s less dangerous to install a low-slope roof not having to deal with pitch while working. Low-slope roofs offer a utility space for large HVAC units to be installed on the roof. It may also cost less to cool down the inside area of low-slope roofs as there is not a large attic space.
Disadvantages Of Low-Slope Roofing
Due to the lack of pitch to assist with water runoff, low-slope roofs require more maintenance than steep-slope. Roof cleaning and inspections should be done regularly on a low-slope roof and a quality roof underlayment system is essential to avoid ponding and the creation of damp areas and leaks.
Steep-Slope Roofing
Let’s have a closer look at some of the pros and cons associated with steep slope roofing.
Advantages Of Steep-Slope Roofing
It’s generally accepted that steep-slope roofs are aesthetically superior. You’re spoiled for choice when it comes to roof coverings. Whether it’s a metal roof you’re after or some Spanish-style clay tiles, a steep-slope roof will suit.
They are more commonly found on residential properties, but some businesses do have steep-sloped roofs. With the increased pitch, homeowners can create a second living space from the attic or storage area. The runoff angle is steep enough to ensure that most water and debris end up in the gutters.
Disadvantages Of Steep-Slope Roofing
Steep-slope roofs are more dangerous and difficult to work on which will often increase labor costs as more safety equipment and expertise are required.
It’s almost impossible to install central air conditioning systems on a steep roof. The roof pitch makes it impractical. Large objects installed on a steep slope will cause run-off to block up against them. Over time this creates leaks and damp problems.
Roof Underlayment For All Types Of Roof Slopes
Tag & Stick understood the need for better roof underlayment and we knew self-adhered underlayment was the future. We needed to provide a code-approved solution that would not delaminate existing roof decking. We also needed a solution that complied with the Florida Building Code.
Tag & Stick’s patented mechanically attached bottom layer and the self-adhering top layer is that solution. Tag & Stick’s self-adhering solution allows roofing contractors to mechanically attach the first layer then the second layer self-adheres directly on top of the first. The result? A 2-ply barrier with a thickness of 115 mils with a superior uplift specification than other roof underlayment solutions.
