While employees in a commercial building may not think about the roof of the building too often, it actually is an important piece in building engineering and sciences. With so many different options and things to consider for your commercial roofing system, it can easily become overwhelming.
To help you out, here is your guide to common roofing materials and what to look for in your roofing systems.
When starting your commercial roofing project, you must talk to a professional roofing consultant or an architect about things like the slope, longevity of the roof, typical weather variations, cost, and energy efficiency.
Commercial roofing is different from residential roofing which is known for having steep slopes.
When a commercial roof is properly designed, installed, and cared for, it can usually last between 20 to 30 years. The lifespan also depends on the type of roof, use of roof, maintenance, climate, and weather conditions of that area.
The overall cost is also one of the main considerations you need to keep in mind when choosing a new commercial roofing system.
An efficient commercial roofing system can not only help you save money but can also work towards greater sustainability as a building manager.
Outlining the main things you want out of your commercial roofing systems will help you make your decision. As part of the guide to commercial roofing, here are the most common types of commercial roofing materials that you might consider using on your commercial properties.
Polyvinyl chloride (PVC) is a type of commercial roofing membrane that is known for being lightweight, highly reflective and providing excellent weathering. As well, this type of material is also UV light, tear, bacterial growth, and puncture resistant.
Additionally, it is resistant to some oils and most chemicals. Because of this, PVC membranes are often recommended for buildings that emit oils from their ventilation systems.
One of the most popular roof types in the roofing industry is a metal roofing material. Metal roofs are very popular because there are so many different kinds of metal materials available for use in a commercial roofing system. As well, metal panels are extremely durable and have a 40-60 year lifespan.
Metal commercial roofs will also have protective surface layers that are added to manage damage from prolonged sunlight exposure and other environmental dangers. They are also known for having strong fire resistance ratings with their fire-retardant properties.
A fire-resistant metal roof, compared to an EPDM roof, also has an attractive, finished look; but, when budget and durability are of the utmost importance, it’s wise to go with what works best rather than what looks best.
A vegetative roof also referred to as a green roof, is made up of a green space that covers your entire roof and can last from 30 to 50 years. They consist of a tough waterproof membrane tolerant of foot traffic, covered completely by green plants. This type is one of the most sustainable and can look amazing when installed properly, making it a great option for apartment buildings.
Green roofs often include protection from elements, climate control capabilities, and water drainage management. A building owner may also use this space for more solar panels which can increase the sustainability of the building structure.
However, one downside is the extensive maintenance and monitoring that is required for your new roof.
Also known as thermoset roof systems, an EPDM roofing membrane system offers long-lasting durability and versatility. As well, EPDM roofs are easier to maintain and repair than other commercial roof types.
An EPDM low slope roof is very resistant to ultraviolet light and ozone and can help lower building owners' energy costs and cooling costs. It's also lightweight, meaning the roof deck does not usually need to be reinforced.
This roofing material isn't the most attractive for commercial buildings and is susceptible to punctures and holes. However, it is cheaper than some of the other commercial roofing types.
Other types of roof materials include:
1. How long can a properly maintained commercial roof last? A well-designed and maintained commercial roof can last between 20 to 30 years, influenced by factors such as roof type, maintenance, climate, and usage.
2. What factors should I consider when choosing a roofing system? Consult professionals for advice on slope, longevity, weather conditions, cost, and energy efficiency to determine the most suitable roofing system.
3. What is the benefit of choosing an energy-efficient roofing system? An energy-efficient roofing system not only saves costs but also contributes to the sustainability of the building.
4. Are green roofs suitable for commercial buildings? Green roofs are sustainable and visually appealing, offering climate control and water management benefits. However, they require extensive maintenance.
5. How does EPDM roofing compare to other types? EPDM roofing is durable, versatile, and energy-efficient. It's resistant to UV light and ozone, though it can be susceptible to punctures. It's cost-effective compared to some other options.
6. What is the purpose of inverted roofing? Inverted roofing uses a waterproofing layer beneath insulation to control temperatures, offering climate benefits while protecting the insulation layer.
