Types of Commercial Roofing
Commercial properties need roofs that can stand up to the elements. They also need to be able to meet energy efficiency requirements and fit into the building’s aesthetic design. Visit Roofing Columbus GA for more details. There are several commercial roofing materials to consider for your next build. Here are some of the most common.
Metal roofs are popular for commercial structures because they offer longevity, durability, and energy efficiency. Their superior weather resistance also makes them an excellent option for buildings in hurricane-prone areas.
There are several different types of metal roofs, each suited for different applications and budgets. For example, corrugated steel panel roofs are one of the least expensive options, and they can be installed over existing roofing to save money on labor. Standing seam metal roofs are a more costly option, but they provide a high-end look that is ideal for modern buildings.
Many commercial buildings use a combination of metal roofs and shingle roofs for added versatility. Metal roofs are available in a wide range of colors, and manufacturers produce coating systems to protect them from weather damage. These coatings can reduce the chance of oil canning, which is a construction defect that causes visible waviness in flat areas of the roof.
Depending on the type of metal you choose and the color coating, a commercial metal roof can last up to 50 years. Some of the most durable metals for roofs include galvanized steel, zinc, and aluminum with Kynar coating. In general, the thicker the roof coating, the longer it will last. However, long-term exposure to the elements will eventually deteriorate the protective finish and require a recoat.
Another important consideration is the impact resistance of a metal roof. Many manufacturers test their metal roofs to ensure that they hold up against common environmental threats, such as hail. A well-designed metal roof should be Class A rated and resist fire, wind, and water penetration.
Finally, consider how a metal roof will fit in with the surrounding architectural style of your building. Metal can create a modern or industrial look, and it can also be designed to blend in with traditional or historic architecture. Also, keep in mind that a metal roof can weigh more than shingles, so be sure to factor this into your building’s structural stability. Also, metal roofs tend to be noisier than shingle or PVC roofs, particularly when it rains.
A shingle roof is a type of roof that is covered in shingles. This is a popular choice for commercial roofing because it can protect the building from weathering, and there are many different types of shingles available to choose from. The most common type of shingle is asphalt shingles, but they can also be made from wood or clay. Choosing the right shingles for your business depends on several factors, including cost and aesthetics.
If your main concern is budget, a regular asphalt shingle roof will be the most affordable option. These shingles are thick and durable, and they can be purchased in a variety of colors to match the design of your building. If you’re looking for a more stylish roof, you may want to consider luxury shingles that have a look closer to quarried slate or wooden shakes. Metal shingles are also an excellent choice for commercial roofing because they can withstand extreme weather conditions, and they are available in a variety of styles to match the design of your building.
Other types of shingles include low-sloped EPDM (ethylene propylene diene monomer) roofs, which are easy to install and maintenance-free, as well as energy-efficient options that are made from light-colored shingles to reflect heat away from the building. These shingles can also help to reduce the amount of solar power needed for heating and cooling.
Another option for commercial roofs with a low slope is rubber roofing, which is long-lasting and waterproof. This is an environmentally friendly alternative to other types of shingles, and it can be made from recycled tires. This is a great choice for businesses located in areas that experience a lot of rain.
A more modern roofing solution is spray polyurethane foam, which can be applied in layers to create a sturdy and watertight surface. This is a great option for businesses that want to be eco-friendly, as it’s made from sustainable materials and uses nontoxic chemicals. This type of roofing is also highly resistant to UV radiation and improves a building’s energy efficiency. This is an ideal choice for businesses that don’t require a flat roof and can be installed on almost any structure.
PVC & TPO Roofs
Single-ply membranes like TPO and PVC are popular options for low-sloped or flat commercial roofs. They’re visually appealing, durable and energy efficient. However, they do have some key differences that may make one more suitable for your project than the other.
Thermoplastic polyolefin (TPO) is a highly heat-resistant and flexible material. Its seams are heat-welded together to form a smooth and watertight top layer. Unlike many other types of roofing materials, TPO is also very puncture-resistant and holds up well to harsh weather conditions and debris that may fall on the roof.
Despite their durability and versatility, TPO’s are still relatively new to the industry. As a result, TPO has experienced a number of problems that have called its reliability into question. These include issues with premature deterioration, poor chemical resistance and inconsistencies between manufacturers.
PVC on the other hand, has a much longer track record of success and has proven to be a superior option for commercial roofs. It does not require plasticizers to remain flexible, and it resists chemicals, sunlight and other aging factors better than TPO.
Choosing the right roof system for your project will depend on your building structure, client preference and the level of field labor required for installation. Both PVC and TPO membranes can be mechanically fastened or fully adhered, making them easier to install than traditional built-up roof systems.
Both membranes are easy to maintain and offer a high SRI (Sun Reflective Index), reflecting UV rays away from the roof rather than allowing them through, which can help cut air conditioning costs. In addition, they are 100% recyclable.
Both TPO and PVC can be installed over existing membranes, making them a great option for projects that need to stay on budget. Regardless of which membrane you choose, it’s important to work with a reputable roof contractor that has extensive experience in the industry and uses products that meet or exceed industry standards. This ensures that your new roof is properly installed and that you get the most out of your investment. For more information on TPO & PVC, contact us today.
Built-up roofs, or BUR for short, are a time-tested roofing system that has been in use for over 100 years. It uses multiple layers of tar and fiber membranes to prevent leaks on flat or low-slope commercial roofs. It is also one of the most durable types of flat roofs on the market, able to withstand high foot traffic and other structural activity.
They are typically installed over a concrete or wood roof deck. The first layer is a cover board that creates a base to protect the rest of the structure and add thickness to the roof. Then, a series of asphalt and ply sheet layers are applied in alternating orders. The ply sheets are usually a fiberglass or organic material. The asphalt can be hot bitumen or cold bitumen. The hot and cold bitumen are used in different ways to bond the ply sheets, mainly due to their varying temperatures and how they melt.
This layered structure offers redundancy, meaning that even if the top layer is compromised by storm damage or normal wear and tear, the other layers will continue to provide protection for the rest of the roof. This also helps reduce energy costs and the risk of fire, since it will keep vapors from escaping the building and heat from entering. The last layer is a surfacing material that may consist of gravel, mineral granules, or other materials. These offer a finished look to the roof and help protect the ply sheets from harsh sunlight or debris.
Leaks can be difficult to diagnose on a BUR roof, because they can travel between the layers of the material. For this reason, you want a professional service crew with experience working on this type of roof and access to the proper tools and equipment.
Built-up roofs are versatile and offer many benefits to the business owner. They are often more cost-effective than other flat roof systems and can be used for solar installations, vegetative (roof gardens) or mechanical areas. They are also a great choice for businesses that need to add structural support for heavier loads on the roof.
