Flat roofs perform and look different from traditional sloped ceilings. Flat roof systems are now available with a variety of unique pros and cons. They also offer a long-lasting lifespan and a low price. These times have changed. In 2021, it is essential to choose roofing systems that are right for you and your company.
A flat roof is generally at an almost horizontal level. However, it can have a pitch of three to twelve inches.
Flat roofs can be less durable than sloped ones and tend to shed snow and rain faster. But, over the decades, advanced materials have been developed that allow flat roofs to evolve to be durable, cost-effective, and competitive with traditional shelters.
Flat roofing is the best option for industrial and commercial properties. For this purpose, a pitched roof does not need to be used. A flat roof is the only option. It offers more space than any other design. It is possible to access this area by workers if it is maintained and inspected regularly. Commercial roofing is best if it has a low slope.
But, being familiar with flat roofing isn’t enough. Business owners need to be familiar with the best-balanced roofing options for their goals and plans.
The sheer number of commercial roofing options available can make it confusing. If you do, your time and investment will be wasted. Business owners should not allow this to happen.
These are the three most important commercial flat roof materials to learn.
- Built-up
- Spray-on
- Membranes with single or multiple layers
They can be grouped into three categories, which makes it easy. Each type will help you find the best options in 2021.
Built-up roofing
Built-up roofing consists of tar-saturated papers – or liquid Tar – mixed with gravel, asphalt, and rolled asphalt. Layers are added to the roof as it is being installed. This is why it is “built up.”
Pros & Cons
– Low installation and material costs
– Low maintenance
– Resistance to foot traffic, ultraviolet rays, punctures
– Finding the leak source is difficult
– Short Service Life (10-15 Years)
– High-priced repairs
-Low energy efficiency
– Not environmentally sustainable
– Low flexibility in cold temperatures
– Release harmful fumes and vapors
– Heavy material
Spray-on Roofing
There are two types of spray-on roofing.
- Spray foam insulation sprays directly onto the roof deck, then apply acrylic or UV coatings.
- Roof coatings usually, they are installed on top of single-ply roofs.
Pros & Cons
Seamless installation
– SPF foam is flexible enough to conform to any roof shape or size
– High R-value – Good insulation and energy efficiency
– No seams
– Minimum maintenance
– It can be added to an existing roof
– If installed properly, it can last for up to 40 years
– Extremely expensive
Installation is difficult
– There is more potential for system failure
– SPF is only available in specific weather conditions
– SPF is often specified for commercial buildings but not residential properties.
– Spray foam roofing releases harmful fumes during installation.
Single-ply Roofing
Sing-ply is only covered by one membrane. It’s the one that protects against weather and water. There are many types of membranes. The most popular ones are the 10-footer. Its average thickness can range from 45 to 90 millimeters.
There are three types of Single-ply roofing: EPDM, EPDM, and TPO.
- Ethylene Propylene Diene Monomer
- PVC (Polyvinyl Chloride).
- TPO (Thermoplastic Olefin).
These roofs are now the best for commercial and residential construction. But they do not have the same longevity and quality. They all have different formulations and specifications.
Pros & Cons
– Solar-reflective and energy-efficient
– Some materials can be recycled
-Can last between 30-40 years
– Systems with hot-air welded seams are waterproof (PVC, TPO).
– EPDM rubber is easy to install and repair yourself.
– Resistant against inclement
– Can be used to create a roof garden or patio
– Be alert for leaks
– Exterior penetrations can lead to leaks without flashing.
– Expensive expert installation and equipment (PVC or TPO).
– Maybe punctured with a sharp object
