There are some parallels between residential and commercial roofing systems in that they both serve the same basic purpose of shielding your home or business from the elements. The size of the structure determines the roof’s slope, which is the primary distinction between residential and commercial roofing systems.
Slate, asphalt shingles, and architectural tile are common materials used on dwellings’ steeply sloping roofs, which are usually visible from the ground. Commercial roofs are often flat or very slightly inclined and are hidden from view from the ground due to the larger scale of these structures.
A variety of materials are available for commercial roofing, depending on the building’s construction and other factors. Elements such as weather, such as severe heat or cold, or whether a surface is required to tolerate a lot of foot activity.
Materials for Commercial Roofs and Contemporary Technology
In order to provide the finest roofing solution for the project, commercial roofing contractors stay up to date on the latest developments in commercial roofing technology. New commercial roofing materials have emerged recently that maximize environmental efficiency and offer strong resistance to temperature extremes, assisting in the reduction of stormwater runoff as well as heating and cooling costs.
Selecting a Business Roof System
When deciding on the kind of commercial rooftop that your company needs, there are a few things to take into account. It is important that you take into account the kind of equipment you are utilizing, as various kinds of enterprises need careful preparation. Making informed decisions will be aided by familiarizing yourself with the various commercial roofing system options.
Commercial Roof Shape
The angle of the roof must be taken into consideration when installing commercial roofing systems. There are two types of roofs: steep slope roofs and low slope roofs, sometimes known as flat roofs.
Low Slope Roofs: Big box businesses, shopping malls, and warehouses all frequently have these kinds of roofs. There are several alternatives available for flat roofs using this roofing system, such as EPDM, PVC, and TPO.
Commercial Roofing System Types
You may choose the roofing system type that best suits your company’s demands after determining the slope of the roof. The most popular commercial roofing systems are shown here.
One Layer of Roofing
Roof systems are made of EPDM, PVC, and TPO. Many building owners choose these materials because they are strong, flexible, and resistant to weather, including peeling and cracking.
One of their primary features is that they are made to be placed in only one layer. Thermoplastic and thermoset membranes are the two primary types used throughout the single-ply roofing market.
Thermoplastic Polyolefin, or TPO
In North America, low slope roofs are the most typical usage for this material, which comprises reinforced roof sheets with heat-welded joints and excellent reflectivity. TPO comprises a single-ply membrane that is usually made of polypropylene and rubber which was originally polymerized together from ethylene and propylene.
TPO is a kind of thermoplastic membrane that is available in several colors, the most common being white, gray, as well as tan. There are many ways to install the membrane: ballasted, adhered, or mechanically affixed.
Polyvinyl chloride, or PVC
A polyester reinforcing scrim is sandwiched between two layers of PVC to create PVC roofing material. Additives in the top ply provide the membrane its UV resistance. Usually darker, the bottom layer has plasticizers added to it for flexibility, making installation simpler.
A PVC membrane’s endurance, durability, including fire resistance are further advantages. Furthermore, PVC may be joined to a neighboring sheet to create a waterproof seal.
By welding the pre-manufactured seam to the surface, PVC sheets may be made to imitate standing seam roof systems at a far cheaper cost while still maintaining an eye-catching appearance PVC membranes may be recycled and used to make new sheets.
Ethylene Propylene Diene Monomer, or EPDM, roofing
What is roofing made of EPDM? The substance noted for its toughness and elasticity, “ethylene propylene diene monomer,” is represented by the letters. EPDM roofing uses a material that is incredibly resistant to the sun’s harmful rays and the continuous barrage of UV radiation.
Due to its ability to combine affordability with durability, EPDM rubber roofing, one of the most widely used commercial roofing materials today, is doubly desired. Oil and natural gas are the main ingredients of EPDM roofing membranes, which are synthetic rubber.
Around the world, low-slope commercial buildings are covered with EPDM roofing material.
Systems of Modified Bitumen Roofing
Asphalt and a special chemical polymer are combined to create a modified bitumen roof that is flexible and temperature resistant. It is a feasible alternative for installation during all four seasons since it can be put in several layers, in a variety of methods (such as self-sticking sheets, hot-mopped tar, torch-applied and cold-applied adhesives), and in both hot and cold temperatures.
To create a strong connection, the seams are fused together. Its resistance to harm during a storm is attributed to its rating against lightning, wind, fire, and hail.
Constructed Roof Systems
Constructed from the ground up, built-up roofing is one of the most traditional roofing systems on the market. It offers superior protection, particularly in regions with dramatic temperature fluctuations. The roofing material consists of three to five layers.
BUR, or built-up roofing, is a relatively new material that has been used for more than one hundred years.
Metal Roofs
Metal roofing is renowned for its durability, endurance, and aesthetic appeal. Applied to steep and low-slope roofs (https://media.iccsafe.org/news/eNews/2013v10n1/2009_ibc_bcbseries_pages130-132.pdf) alike, metal roofs are preferred by many building owners for its longevity and attractive appearance.
Due to the extended lifespan and durability of some types of metal roofing over standard shingle roofs, building owners and homeowners are increasingly choosing them.
Roofing Applied Liquid
Reinforcing polyester and resin are used to create a liquid-applied roofing membrane that is permanently installed. Due to its ability to reach places that are more difficult to reach, it provides enhanced waterproofing capabilities. It is frequently applied with a roller or sprayed on in two different coats.
Because of the way a liquid roof is placed, it doesn’t cause intrusive disruptions or emit offensive or strong smells, which makes it an ideal choice for situations in which companies must remain open while work is taking place.
Systems for Coating Roofs
This completely adherent layer is made up of a membrane that is applied fluidly. It has the ability to flex and revert to its previous form.
Although there are many different kinds of roof coatings, silicone and acrylic are the most often used. Coatings, which are most effective on metal roofs, may save energy usage, keep buildings cooler, stop leaks, and increase the lifespan of commercial roofs.
