When choosing a roof for your home or business, you have many options. Two popular choices are low-slope and flat roofing systems. By comparing these two types, you can decide which one is best for your needs. Here is a brief guide to low-slope and flat roofing. Let’s learn the difference!
Low-slope roofing has a shallow pitch. The roof’s rise is not steep and slopes gently from the center toward the edge. Low-slope roofs are common on commercial buildings and some residential homes. The types of low-slope roofing include built-up asphalt, modified bitumen, and single-ply membranes such as EPDM (ethylene propylene diene monomer) and PVC (polyvinyl chloride).
Built-up asphalt roofs are popular for their longevity and affordability. Modified bitumen is similar to built-up asphalt but has reinforcements, making it stronger yet lighter. Single-ply membrane systems like EPDM or PVC offer excellent performance compared to other types of low-slope roofs. They’re lightweight yet durable enough to provide long-term protection against extreme weather conditions.
Flat roofing has a level surface. These roofs are common on commercial buildings but can also work well on residential homes. Many different materials are available for flat roofing, each with benefits and drawbacks. TPO (thermoplastic polyolefin) is a single-ply membrane that has become increasingly popular due to its durability and resistance to UV radiation. It’s also relatively inexpensive compared to other flat roofing materials, making it a great option for budget-conscious projects. Flat metal roofs offer superior strength and protection from water damage. Concrete flat roofs are perfect for areas prone to high winds or heavy snowfall, as they can support the weight without sustaining damage over time.
The major differences between low-slope and flat roofing include cost, installation, and performance. Low-slope roofs are generally more affordable due to their simple construction with few layers of material. Flat roofs require more labor and materials for installation since they need additional reinforcement to ensure an even waterproof seal across the entire surface.
The installation process for both roof types varies based on the materials. Flat roof installations often require an extra layer of protection through a rubberized coating that acts as an adhesive between each sheet of material. It’s important to consider how each type will perform under different weather conditions, as they can influence your decision depending on your location. Low-slope roofs tend to do better in areas with high rainfall, while flat roofs may not perform as well.
Now that you know the major differences between low-slope and flat roofing, you can determine the best choice for your home or business. If you choose a metal roofing material for your flat or low-slope roof, contact American Metal Roofs for a high-quality professional installation.
