A safe and well-built roof is an essential element of a building’s structural integrity. It is the main line of defense against harsh weather conditions, extreme temperatures and even fire events. As a commercial property manager or facility owner, it is important to be aware of the basic facts about your commercial roof, including the common myths and misconceptions that surround it, in order to make timely and accurate decisions involving repair, replacement and maintenance services.
Myth #1: Taking care of roof repairs after the damage has been done helps save money. The only effective way to save money is to perform preventative maintenance. Any skilled and experienced roofing professional will attest to the importance of regular inspections and maintenance services when it comes to preventing extensive leaks and other water-related damage, such as waterlogged underlayment, rotted decking and mold and mildew growth, all of which can remarkably affect the structural integrity and performance of your roofing system. Remember, an ounce of prevention is worth a pound of cure, and it without fault rings true to commercial establishments.
Myth #2: Commercial roofing systems do not need a maintenance program. It is considered an industry standard that realty investors and property managers ensure that commercial roofing is examined twice a year, preferably in spring and fall, to mainly prepare for a shift in weather patterns that may compromise the strength and durability of the roofing system.
Frequent inspections, along with written guidance reports and photo documentation, allow you to correctly assess areas that need restoration efforts as soon as possible. Overall, a maintenance program guarantees the longevity and efficiency of your commercial roof, consequently heading off thousands of dollars that would otherwise have gone to cumbersome repairs.
Myth #3: Covering damaged shingles with new ones is an effective way to repair the roof. Re-roofing is the process of layering brand-new shingles on top of already existing ones as a means to restore the appearance of the roof. While there are times when re-roofing is a sound option, such as when the roof is in relatively good condition and does not have any soggy or missing shingles, it is generally not advisable to re-roof a commercial system that is vulnerable to further damage. Other factors like the material and pitch of the roof and age of the establishment must all be taken into account as well. Moreover, when the topmost layer of the roof is in need of repair, it typically indicates that other parts of the roofing system have also sustained damage, particularly the roof decking or sheathing that sits underneath the shingles. Much like the roofing material, this concealed component can decompose because of leaks, old age or insufficient ventilation.
Since re-roofing does not address any substantial issues like rotting and other forms of moisture-related damage, it has a shorter effective lifespan than a complete roof tear-off. It is also not recommended for metal roofing. To truly give your commercial roof a new lease on life, replacing the entire roof down to the decking is the best route. It not only addresses all underlying issues your roof may have, but also offers a significantly longer service life and, above all, prevents roof collapse that may otherwise be injurious to the employees, tenants or customers.
Shape of Commercial Roofs
A fundamental thing you need to know about when choosing a type of commercial roofing system is the slope. Generally, commercial roofs fall into two main categories: low-slope and steep-slope.
Low-slope roofs are common among warehouses, big box stores and shopping centers. These roofing systems are classified as built-up, single-ply membrane or modified bitumen. On the other hand, steep-slope roofs are usually seen on single- and multi-family properties. These roofing systems can be covered with shingles, slate or metal.
Types of Commercial Roofing Systems
Once you have determined the slope of the roof, you need to select the type of roofing system that best meets the needs of your business. Some of the most widely used commercial roofing systems are:
Built-up roofing, also called BUR, is the most common roofing material used on low-slope roofs. It consists of three to five alternating layers of reinforcing fabric and bitumen (asphalt), and is finished with a layer of stone or gravel on the top. Thanks to its enhanced protection, BUR performs incredibly well in climatic conditions with wide ranges of high and low temperatures. This roofing system is said to be around for over 100 years.
Single-ply roofing is wide width sheeting meant for low-slope roofs. It can be applied with different types of membranes, namely thermoplastic polyolefin (TPO), ethylene propylene diene monomer (EPDM) and polyvinyl chloride (PVC). These roofing systems are extremely flexible and robust, and can resist peeling, cracking and other forms of weathering. The main characteristic of single-ply roofing is that it is designed to be installed in a single layer.
Modified bitumen roofing is one of the longer lasting options for buildings with low-slope or flat roof structures. It combines asphalt and a unique chemical polymer for increased flexibility and temperature resistance. Unlike single-ply roofing, it can be applied in multiple layers and several techniques, such as self-adhesive sheets, hot-mopped asphalt, torch-applied or cold-applied adhesives. Since it does not pick and choose which temperature is optimal for installation, it is a viable option for commercial application through all four seasons. Modified bitumen roofing systems are rated against fire, hail and wind.
Metal roofing is used on both low-slope and steep-slope roofs. Many building owners prefer metal roofing over other commercial roofing materials due to its string of impressive advantages. Metal roofing can sustain 140 mile per hour (mph) winds without experiencing damage, will not spark or catch fire and does not attract insects. In some instances, it can also help reduce cooling costs by as much as 25%. With proper care and maintenance, metal roofs can last anywhere from 40 to 70 years.
Liquid-applied roofing consists of multiple components that form a fully adhered, seamless and self-flashing membrane. It offers superior waterproofing protection because it is able to cover areas on the roof that are typically hard to reach. It can be sprayed-on or roller-applied, usually both in two separate coats. A liquid-applied roofing membrane does not require an invasive application or emit harmful or strong odors, making it an excellent option for businesses that need to continue their operations during the installation.
