    If you own a commercial property, it is important to recognize the importance of your roof. Your roof is what keeps your building, employees, and customers safe. Whether it is long past its prime and requires a replacement, or you are simply looking to update it, you may be wondering what type of roofing system is ideal. Below, we will dive deeper into five of the most common commercial roofing types and their benefits so you can make an informed decision for your unique property. Keep reading to learn more about the various types of commercial roofing systems.


    Duro-Last Single Ply

    Duro-Last is a premier manufacturer of single-ply PVC (Polyvinyl Chloride) roofing systems. It has been around since 1978 and has served many commercial and industrial buildings, especially those with flat, low-sloped roofs. Not only is Duro-Last Single Ply leak-proof and maintenance-free, it is also resistant to high winds, fire, and chemicals.

    Each and every Duro-Last Single Ply roof is custom made to the exact size of the roof in a controlled factory environment. It is also highly rated by the EPA’s ENERGY STAR Roof Products Program, allowing for significant energy savings.

    Oftentimes, a Duro-Last Single Ply roof can be installed over an existing roof, saving money on a costly tear-off and there are no hazardous materials or loud machinery involved during installation. Best of all, all Duro-Last products, including Duro-Last Single Ply, are backed by a transferable 15-year full warranty or a 20-year prorated warranty for maximum protection. All of these reasons make Duro-Last Single Ply a great material choice for your commercial building.


    Composition Shingles


    Also known as composition shingles, asphalt shingles are usually organic or fiberglass. There are a variety of colors and designs available to meet your particular aesthetic needs and design preferences. Regardless of the size of your commercial building, asphalt shingles are bound to cover it seamlessly.

    One of the greatest advantages of asphalt shingles is their lower cost and easy installation. Compared to other roofing materials, they are far more affordable. Despite being affordable, they are highly durable, lasting anywhere from 30 to 50 years. We, at Landmark Roofing and Siding, highly recommend composition shingles for commercial roofing applications. Your entire shingle system, including underlayment, flashings and vent system will all be installed by our experience roofers.


    Metal Commercial Roofing

    Metal roofing is often a preferred choice for commercial roofing applications because of its lightweight nature, seamless installation, and extreme durability. In most cases, metal roofs are made of corrugated galvanized steel, but some are also comprised of other materials, like aluminum and tin.

    Although, you will pay more for a metal roof upfront, you will enjoy very minimal maintenance and an exceptional fire rating. While an asphalt roof has a typical lifespan of 30 to 50 years, a metal roof will usually last between 40 to 70 years, depending on how well you maintain it. Therefore, even though it is more expensive, you will save money in the long run as you will have fewer repairs and will not need a replacement for decades.

    If sustainability is a priority, you will be pleased to learn that a metal roof can help you reduce your carbon footprint as it is completely recyclable, and won’t clog up landfills. Plus, you can install a metal roof on top of an existing roofing system and reduce the environmental impact that comes with disposing of the old roofing material.


    Spray Foam Roofing

    Whether you plan to build a new commercial property or update your current roofing system, a spray foam roof should be on your radar. It is designed to provide exceptional insulation without the use of any extra products or resources. This can lead to lower energy bills and reduce your overall overhead costs.

    If you opt for a spray foam roof, you can expect a quick, easy installation process with minimal disruptions. Once the roof has been spray coated, you won’t have to replace it completely like you would with a typical roof. Instead, just add a fresh coat to keep it in good condition. The average lifespan is 15 to 20 years, but it may last longer if you prioritize maintenance.

    There are two types of spray foam roofs for commercial buildings: the open-cell foam system and the closed-cell foam system. We recommend the closed-cell route as it offers greater density and insulation.




    Thermoplastic polyolefin, or TPO, is a single-ply roofing system that is a particularly good option if you have a flat roof. Since TPO roofs are usually white, they reflect the sun’s UV rays and improve energy efficiency. Plus TPOs are quite resistant and do a great job standing up to hail and other extreme weather conditions.

    If you invest in a TPO roof, you don’t have to worry about mold growth. As long as it is installed correctly and maintained properly over the years, a TPO roof can last for up to 25 years. Its smooth surface offers dependable protection from the accumulation of dirt and debris that can lead to premature aging.

    How to Choose the Right Commercial Roofing System

    Not all commercial roofs are created equal. The right option depends on your unique situation. Before you make a decision, consider factors like your budget, aesthetic preferences, installation timeline, and priorities. We advise speaking with a professional roofing contractor and having them perform an inspection of your building and current roofing system in order to provide the best possible recommendation.

    For instance, if energy efficiency is key and you do not mind paying a bit more for a roof, a metal roof is likely the way to go. However, if you are on a budget and looking for a versatile option, an asphalt roof might be the better route. At Landmark Roofing and Siding, we are happy to educate you further on your commercial roofing system options and help you make an informed decision for your unique needs.
