The best profiles for use in low-slope projects will be mechanically locked metal roof systems. Mechanically stitched panels are molded with specific edges that align with each other. Once the two panels are attached, a manual or robotic sealer (check out our friends at Quality Roof Seamers) is used to fold the edges and join the panels together. Low-slope metal roof systems typically range in weight between 40 and 135 pounds per 100 square feet, making them one of the lightest and easiest to install Roof Repair in Charleston SC products. A lightweight Roof Repair in Charleston SC system also places fewer demands on a building's structural support system, an important consideration in areas prone to earthquakes. Unlike non-metallic systems that require an underlying substrate or platform, low-slope metal roofs can be applied directly onto bar beams or straps.
In addition, due to their active or interlocking fastening systems, metal roofing panels are designed to meet the requirements of ASTM E1592, UL 580, UL1897 and other high wind and lift tests. Metal roofing products come in a variety of materials, as well as in many colors, textures and profiles. To ensure a longer lifespan, almost all low-slope roofing materials are protected from the elements by high-performance, high-durability metal coatings. Although the idea of protecting a building with metal originated centuries ago, the concept is still valid today.
Whether the goal is to achieve many years of low cost, low maintenance and trouble-free performance or to adopt an environmentally responsible roofing approach, metal roofs with a low slope make sense. The slope varies depending on the type of roofing material used and may vary at different points on the same roof due to the overall design of the house. For more than 30 years, Bill Ragan Roofing has been helping homeowners understand the do's and don'ts of replacing residential roofs. Not only can low-sloped metal roofs contribute to final results, but they can also contribute to LEED credits, which are awarded to buildings that use a high content of recycled material and other “green building materials”.
You might be wondering if a metal roof is a good idea, or even possible, when working with such a low slope. Although the panel has exposed fasteners, it has strength and durability thanks to its 1.23 ribs in height, making it compatible with a roof with a slope of 1 in 12 or more. The appearance of a leak is the number one problem in metal roofs, as it can cause significant damage and generate high repair costs. Flat roofs are frequently seen in commercial buildings, but they are not uncommon in more modern architecture.
In addition, low-slope metal roofs are not prone to the degradation experienced by organic materials, allowing these roofs to better withstand the elements. However, you can still use it on a flat roof by adding the required slope with a built-in roof system. It currently has a very old metal roof with vertical joints that has been covered with a lot of tar or rubber or something like that. Metal roofs are a great option for low-slope roofs, but they should not be installed on a completely flat roof. A metal roof with vertical joints (also called a hidden seal) is locked at the joints with clips or is seals mechanically.
A typical metal roof with a low slope has at least 25% recycled content and, at the end of its long lifespan, is 100% recyclable.

When researching roofs with low, steep slopes, you may encounter the terms “hydrokinetic” and “hydrostatic”” to describe a roof system.
