Understanding Commercial Roofing Systems
The world of commercial roofing systems may seem vast and confusing at first. However, understanding the various types of commercial roofing systems can guide you to make informed decisions for your project, taking into consideration factors such as slope, building usage, and materials. From low slope roofs in commercial buildings to steep slope roofs in residential structures, each type of commercial roofing system presents unique benefits and challenges.
Now, let us navigate through the diverse world of commercial roofing systems and decipher the intricacies of their types.
Low Slope vs. Steep Slope Roofs
Low slope roofs, also known as flat roofs, are commonly found in commercial buildings, while steep slope roofs are more typical in residential structures. Low slope roofs have a minimal incline, providing better water runoff and easier installation compared to their steep slope counterparts. On the other hand, steep slope roofs offer excellent water and snow runoff, but their steep incline can make maintenance more challenging and expensive.
The choice between low slope and steep slope roofs depends on factors such as the building’s purpose, geographical location, and aesthetic preferences. Knowledge of the differences between these two types of roofs will guide you in determining the most suitable option for your commercial property.
Commercial vs. Residential Roofing
Commercial and residential roofing systems have some key differences:
- Commercial roofs tend to be larger in terms of square footage and usually feature a low or flat slope.
- Residential roofs are typically smaller and possess a steeper slope.
- Slope commercial roofing experts possess specialized training and experience in dealing with larger roofs and intricate commercial structures, including metal roofing systems.
When it comes to materials, residential roofs commonly utilize asphalt shingles. On the other hand, commercial roofs may employ a variety of materials, including:
- Metal
- EPDM
- TPO
- PVC
This variation in materials and design accommodates the unique requirements of commercial buildings, such as energy efficiency, durability, and resistance to weather conditions.
Common Types of Commercial Roofs
Whether you are constructing a new commercial property or renovating an existing one, you should familiarize yourself with the common types of commercial roofs. The type of roof you choose will depend on factors such as the building’s structure and your specific needs. Types of commercial roofs typically include flat, low-sloped, and pitched. Each type is constructed differently to meet the needs of a variety of building structures. Each type has its own advantages and disadvantages, making it vital to assess your building’s specific needs and requirements before making a decision.
In the following sections, we’ll examine these common commercial roof types in detail to assist you in making an informed choice.
Flat Roofs
Flat roofs have been a staple of commercial flat roofing since the 1920s. They are cost-effective, energy-efficient, and simple to maintain, making them an attractive option for many commercial properties. However, flat roofs may suffer from inadequate drainage and necessitate experienced contractors for installation and repairs.
To circumvent potential issues with flat roofs, it is advisable to hire a seasoned commercial roofing contractor who is well-versed in the placement of drains and the suitable elevation to prevent puddling. They can also recommend the best materials for your flat roof, such as ethylene propylene diene monomer (EPDM) rubber, modified bitumen, or spray polyurethane foam.
Low-Sloped Roofs
Low-sloped roofs, also known as ‘flat roofs’, have a minimal slope for water drainage and are cost-effective, energy-efficient, and easy to maintain. Materials commonly used for low-slope roofs include shingles, membranes, and metal. A well-installed and maintained low-sloped roof can have a lifespan of up to 40 years, offering numerous benefits for commercial property owners.
However, low-sloped roofs may be susceptible to heavy snow loads and must comply with building regulations. Despite these challenges, low-sloped roofs remain a popular choice for low slope commercial buildings such as factories, warehouses, and apartment buildings due to their efficiency and ease of installation.
Pitched Roofs
Pitched roofs provide excellent water and snow runoff, making them a suitable option for commercial properties in areas with heavy precipitation. However, their steep incline can make maintenance more challenging and expensive. The materials used for pitched roofs in commercial settings can vary, with some popular choices being:
