5 Types of Roofing Materials Used on Commercial Buildings

Roofing is a critical aspect of commercial building construction, providing protection against weather elements and contributing to energy efficiency. The choice of roofing material plays a pivotal role in determining the longevity, sustainability, and aesthetic appeal of a commercial structure. This article will delve into various types of roofing materials commonly used in commercial buildings.

Built-Up Roofing (BUR)

Built-up roofing (BUR) is a tough and dependable roof used in many commercial buildings. It’s made of layers of strong material soaked in bitumen, creating a sturdy, waterproof layer. These layers are stuck together using hot asphalt or cold adhesive. The top layer often has gravel or mineral granules, protecting it from the sun and weather. BUR works well on flat or low-sloped roofs, offering great durability and weather resistance. Though installing it can take effort, BUR is cost-effective due to its long life and low maintenance. Its fire-resistant feature adds to its safety, making it a top choice for many commercial buildings.

Metal Roofing

Metal roofing is a modern and flexible choice for commercial buildings, combining strength, energy efficiency, and good looks. It’s made from materials like steel, aluminum, or copper, ensuring durability against fire, insects, and bad weather. You can choose from different styles like standing seam, corrugated, or metal shingles to give your commercial structure a sleek and contemporary appearance. Metal roofs are lightweight, making installation easier and reducing labor costs. They reflect sunlight, helping with energy efficiency and lowering cooling expenses. While the initial cost might be more than some traditional options, the long lifespan and low maintenance needs make metal roofing a smart and eco-friendly decision for commercial buildings looking for lasting performance and an attractive exterior.

Slate roofing

Slate roofing is a timeless and durable choice made from natural stone. It’s been popular for many years due to its elegance and lasting qualities. MLR Slate Roofing tiles, extracted from quarries, come in different colors and sizes, giving a unique look. Although it might be more expensive at the beginning, slate roofing is cost-effective in the long run. It can withstand weathering, is resistant to fire, and needs minimal maintenance. Slate roofs are often chosen for historic and fancy commercial buildings, giving them a charming and classic look. Slate also helps with energy efficiency, making it a sustainable option for those who want both good looks and practical benefits in their roofing material.

Modified Bitumen Roofing

Modified bitumen roofing is a step forward in roofing technology, combining the strength of traditional materials with modern improvements. It’s made of asphalt-based sheets reinforced with modifiers like Atactic Polypropylene (APP) or Styrene-Butadiene-Styrene (SBS), enhancing flexibility and resistance to temperature changes. This creates a tough and adaptable roofing layer. Applied in multiple layers, it provides excellent waterproofing and UV protection, making it great for flat or low-sloped commercial roofs. You can install it using methods like heat-welding or cold adhesive, offering flexibility. With its ability to handle tough weather and easy repair, modified bitumen roofing is a reliable and cost-effective choice for commercial buildings that want a durable and long-lasting roofing system.

Green Roofing

Green roofing is an eco-friendly choice for commercial buildings, blending nature and architecture for a sustainable impact. This innovative system involves growing plants on the rooftop, bringing various ecological benefits. There are two main types: extensive and intensive, offering different plant diversity and weight loads. Apart from looking good, green roofs improve insulation, reducing energy use and cutting heating and roof cooling expenses. They act as a natural filter, managing stormwater runoff and enhancing air quality. While the initial costs and structural aspects may be higher than traditional roofing, the long-term environmental perks, like carbon sequestration and increased biodiversity, are making green roofing more popular for commercial buildings aiming to boost sustainability and create a healthier urban environment.

Solar Roofing

Solar roofing integrates solar panels into the roofing material, transforming commercial buildings into renewable energy sources. This eco-friendly option not only generates electricity but also shields the structure from the elements. The advancements in solar technology allow for seamless integration, enhancing the aesthetic appeal of the building. While the initial investment may be higher, the long-term savings on energy costs and reduced environmental impact make solar roofing an increasingly popular choice for commercial buildings striving for sustainability and energy efficiency.

Choosing the right roofing material for a commercial building involves considering factors such as climate, budget, energy efficiency, and aesthetics. Each type of roofing material comes with its own set of advantages and considerations. Whether opting for traditional materials like BUR or embracing innovative solutions like green or solar roofing, commercial building owners have a range of options to ensure a durable, efficient, and visually appealing roofing system for their structures.
