6 Most Reliable Roofing Systems For Commercial Buildings

Commercial buildings are the Financial hubs of a city and center of trade. Therefore, it is necessary to ensure that all the protective measures are taken in order to assure security from all the disasters.

The most important thing to protect is the roof in the buildings. Because, if the roof collapses or there is some issue in it, it poses a danger to the people under it. Hence, it is necessary to have robust and reliable roofing systems for Commercial Buildings.

We partnered up with the best roofing company in NYC to learn about the most reliable roofing systems for commercial buildings. We chose New York City for our research because it is the world’s commercial hub, and New York is classed as having a continental climate that enjoys all four seasons.

What are Commercial Roofing Systems?

Big box businesses, malls, and apartment complexes, to mention a few, are all protected by commercial roofing. Their objective is similar to a home’s roof, but everything else about them, from the resources used to the upkeep required, is quite different.

Each of these business roofing systems has its own set of advantages, functions, and upkeep requirements. In any case, we’ll walk you through business roof installation, repair, and maintenance to guarantee that your commercial structure is safe and secure for years to come.

Most Reliable Roofing Systems For Commercial Buildings

1. Asphalt or Modified Bitumen Roofing Systems

A modified bituminous roof blends asphalt with a special chemical polymer for elasticity and thermal resistance. It may be installed in many layers, in a variety of techniques (self-adhesive sheets, steamy asphalt, torch applied, or frozen adhesives), and in both high and low temperatures, making it a suitable solution for all four seasons. To produce a secure connection, the seams are melted together. They are wind, flame, and hail resistant, which means they will not be harmed during a thunderstorm.

These systems are overlapping, which means that if one layer fails, the others give quick protection. These systems also have a more significant threshold for building tension and thermal shock resistance, as well as exceptional barrier strength and toughness for long-term endurance.

2. EPDM Roofing Systems

Let us first comprehend ‘EPDM.’ It stands for “Ethylene Propylene Diene Monomer,” a difficult-to-pronounce chemical molecule with high flexibility and durability.

EPDM roofing is made of a fabric that can resist the continual bombardment of UV radiation and all of the sun’s harmful rays. Today, it is the most common commercial roof tile because it combines cheap cost with tensile strength. EPDM roofing membranes are made out of natural gas and oil-based synthetic rubber. EPDM roofing is widely employed in low-slope commercial structures across the world.

Because its waterproofing guards the insulation against the summer heat and the cold in the winter, a roofing contractor using an EPDM roof coating will save money on energy expenditures related to heating and cooling the structure.

3. PVC Thermoplastic Roofing Systems

Polymers make thermoplastic membranes, which soften when fired and solidify when cooled. These factory-made sheets are installed using conventional sheet membrane installation processes on the project site. This technique can be repeated as long as the substance is not overheated beyond the breakdown point. The membranes may be welded together by temperature or solvents, and the resulting bond strength equals or exceeds the underlying material’s strength. The most prevalent thermoplastic roofing membranes are polyvinyl chloride (PVC), PVC mixes, or alloys.

Because of its lower cost and abundant availability, PVC has become a popular alternative. It’s also wind-resistant, making it appropriate for specific climates and places.

4. TPO Roofing Systems

A newer type of commercial roofing material is Thermoplastic Polyolefin (TPO). It was first seen as a roof covering in 1986 and is acclaimed as a low-cost, low-maintenance alternative to PVC.

TPO membranes are single-ply membranes made of polypropylene and ethylene-propylene elastomer that have been polymerized together. TPO is a thermoplastic membrane that comes in several hues, with white, grey, and tan being the most prevalent. Mechanically connected, glued, or ballasted membranes are only some of the options for installation.

The significant benefits of TPO roofing systems are strong air welded seams, high resistance against high winds and heat, and the ability to withstand any sudden temperature shifts from hot to cold or vice-versa.

5. PMMA or Liquid Applied Roofing Systems

Resin and reinforcing polyester are used to form a liquid sprayed roofing membrane in situ. Because it can reach such hard-to-reach locations, it has higher waterproofing characteristics. It’s commonly coated in two coats, sprayed or roller applied. Because of how it’s poured, a liquid roof doesn’t cause obtrusive disruptions or release hazardous or intense aromas, making it a viable alternative for companies that need to remain open during development.

According to the Manual, liquid applied membrane roofing consists of hot and cold polymer-modified asphalt, solitary asphalt or coal tar-extended urethane, and two-component urethane elastomer. Liquid applied membrane methods need meticulous substrate preparation, which must be dry dust-free, and fissures must be addressed.

While liquid applied films are very elastic, self-flashing, and easy to use on curved surfaces, their permeability is poor, and consistent thickness is required.

6. Metal Roofing Systems

Because of its prolonged life and sturdiness, metal roofing is a popular choice for residential and commercial structures. It may be found in various styles, shapes, sizes, and metal kinds. Galvanized steel, aluminum, metallic tiles, copper, or even polished stainless steel might be used in commercial constructions. All of which are pretty durable and aid in preventing breakage and water leaks.

Metal roofing may assist in reflecting the sun’s rays, improve HVAC performance, and be treated or covered to avoid corrosion and fading. They also look prominent if you want a more clean, modern aesthetic, and they’re recyclable, so they’re a sustainable option.

More importantly, this choice favors because this roofing system is simple and easy to re-roofing for your old, almost worn-out roofs.


This article has provided you with the essential knowledge and information regarding all the major roofing systems for commercial buildings. You can study all these techniques and adopt the one which suits your cause the most.

However, even if the roofing system is robust, the constructors must be skillful to implement it. You must check the track record and the reputation of the contractor for higher quality assurance.
