What Are The Different Types Of Commercial Flat Roofs
Flat roofs are the preferred roofing option for most businesses since they're relatively easy to install. Flat roofs are also affordable as they require fewer roofing materials than pitched roofs. Additionally, flat roofs are easy to maintain since roofers can walk around the roof. Installing solar panels on a flat roof is also more straightforward than on a sloped roof. Given the benefits, consider installing a flat roof for your business. Here are the various commercial flat roofing options to consider.
Built-Up Roofing (BUR)
BUR systems consist of semi-flexible membranes made of plies or felt. Roofers alternate the plies layers with bitumen, gravel, or aggregate for improved strength and durability. This is why BUR systems are sometimes referred to as gravel or tar roofs. The roofs are low maintenance and can last for years. However, built-up roofing requires extra insulation to achieve high energy efficiency.
Single-Ply Membrane Roofing
Single-ply commercial flat roofing systems are lightweight, hence, they are easy and fast to install. There are two types of single-ply roofs:
Thermoset membranes (EPDM). Ethylene Propylene Diene Monomer is a rubber-like material that offers impact and weather resistance. Hence, EPDM roofs are durable and low maintenance. However, the roofing material is typically black and is not capable of reflecting heat well. But you can introduce a light-colored ballast to improve your roof's energy efficiency. EPDM roof installation entails welding the single-ply membranes to create seams that make the roof waterproof.
Thermoplastic membranes (TPO and PVC). Thermoplastic polyolefin and polyvinyl chloride are white and highly reflective. Hence, the roofs offer better energy efficiency, and you can spend less on cooling. Also, the roofing provides chemical resistance.
Metal Panel Roofing
The most common metal panel roofs are aluminum and stainless steel. The roofs come in panels, which roofers join together with adhesive at the edges of every seam. This makes the roof water-resistant and increases the roof's overall strength. Also, metal roofing can withstand harsh weather and impact, increasing the roof's lifespan.
Green roofs are eco-friendly and attractive. A green roof usually has multiple layers that protect the building and support the vegetation. However, installing green commercial flat roofing is complex and costly, making these roofs rare. Generally, green roofs are becoming popular in restaurants and entertainment businesses due to their aesthetic value.
The most common commercial flat roofing options are BUR, green roofs, metal panel roofs, and single-ply membrane roof systems. Consider these options in your next commercial flat roofing installation project.
