No matter if you’re building a brand new commercial building or moving into a 100 year-old old facility, the roof is one of the most important structural elements to your commercial building. Your roof protects your building from rain, snow and hail. It also keeps the inside either hotter or cooler during the summer and winter, and protects everything inside.
If you want to keep this important structure doing its job, your commercial roofing must be installed correctly, taken care of regularly, and replaced when necessary.
6 Signs Your Commercial Building Roof Needs Repair
If you have a commercial building that is getting older in age, it might be a good idea to check on the roof. These common problems may indicate you need a repair, but can be quickly fixed before you’re faced with replacing the whole roof.
- Moisture Problems – Anytime your roof is not absolutely watertight, you are susceptible to moisture damage. This can be caused by storms, snow, or high humidity. If you have noticed any water stains on ceilings or an increase in insect or rodent problems that could mean water is getting in through the roof, and coming into the walls through the insulation. This means it is time to call for a commercial roofing repair as soon as possible.
- Climbing Energy Bills – If you notice your electric bills in the summer are increasing, it could be due to your roof. When your roof loses reflectivity, your cooling system must work harder to maintain comfortable temperatures. In Louisville, KY this could be a huge drain on your budget during the hot summer months.
- Bubbles – This one is difficult to see from the ground, but if you have the ability to get on top of the roof, you can check for bubbles. These are caused by moisture coming up under the top level of your roofing material. A few bubbles is OK but the more bubbles, the sooner you need commercial roof repair.
- Sagging – While bubbles indicate a problem on the top surface of your roof, sagging or low spots indicate a problem below the surface. There could be several root causes, it may be previous ponding that compressed the roof insulation, or a problem with the roof deck joint. Either way, a sag in your roof is a good reason to call for a repair.
- Open Seams – Any time you see seams starting to open up, that leaves you susceptible to water damage. Any time there is a crack or an open seam, water will find its way in. Any time you find a seam that is not sealed, it’s time to call for a repair.
- Clogged Drains – During the next Louisville rainstorm, look at your exterior downspouts. If your downspouts aren’t running off adequately, you likely have clogged drains and therefore ponding on the top of your roof. These are strong signs you need commercial roofing repair. Leaving water ponding on the roof, will only lead to bigger problems.
6 Signs It’s Time to Replace Your Commercial Building Roof
- Damaged Roof Membrane – This is the easiest way to tell if there’s major irreparable damage to the roof. Strong winds or storm damage in Louisville, KY will eventually cause severe uplifting on your roof membrane. Look carefully at any parts of the roof that are lifting. If 25% or more of the roof is lifted, or if you actually see large bald spots, it’s time to consider a roof replacement. If you leave it alone, the next storm will put rainwater damage into your roofing, insulation, and eventually down your walls.
- Considerable Wear and Tear on the Roof Deck – If you are able, take a walk on your roof and get a good look at the roof deck. The signs of continued moisture damage aren’t that obvious initially, but if you check it frequently, and you see considerable changes on your roof deck, you might want to consider a commercial roofing repair or full commercial roof replacement.
- Visible Water Infiltration – Are there any visible watermarks or stains on the walls or in the attic of your building? These are indicators your commercial roofing isn’t holding up very well. Once you have water damage on the inside of your building, it means both the roof membrane and the secondary protection level are failing. We recommend that you have your roof inspected and prepare for a commercial roof replacement.
- Your Property Isn’t Well Insulated Anymore – Check to see your property’s level of insulation. The best way to do this is to check your electric bills and compare them to the same time last year. Your commercial roof is designed to protect the integrity of your interior insulation. If you notice your bills have increased over time even if your usage is normal, then it’s worth checking on your roof.
- Blistering – Blistering is caused by water trapped inside the insulation of your roof. This process actually causes a release of gases, which causes blistering on the roof. If you notice this started to affect your roof, it’s time to call for a commercial roofing repair or replacement.
- Shingle Damage – Not all commercial roofs have shingles, but if yours does – you should have them inspected for damage. Any time you have shingles that are cracked, curled, or split, it can cause havoc. Also watch for patchy spots of moss, which is often an indication of trapped moisture.
Types of Commercial Roofs We Offer
TPO (Thermoplastic Polyolefin)
Thermoplastic Polyolefin is one of the fastest growing commercial roofing systems on the market. A TPO roofing system is a single-ply roofing membrane made up of a single layer of synthetics that can be used to cover flat roofs. These are popular because the surface is naturally reflective. Additionally, they are easier to install and more reliable than other materials.
TPO membranes are manufactured in sheets that are 10, 12 or 20 feet wide. The sheets are manufactured off site and then rolled and transferred to the work site for installation. Today, about 40% of commercial roofing installations are TPO.
EPDM (synthetic rubber)
EPDM is an extremely durable synthetic rubber roofing material. It is used worldwide and is one of the most popular flat roof systems. It’s widely used because it is sold in a variety of widths and thicknesses to meet your needs and is the most durable material on the market. In fact, EPDM rubber roofing has the industry’s longest single-ply average lifespan at 25-30 years. It can be used on a variety of roofing shapes and slopes and has a very high resistance to wind, hail, UV radiation, and extreme temperatures.
Modified Bitumen (MB) roofing is a 5-layer asphalt-based material that is best for low-slope or flat roof structures. This material originated in Europe and has been used successfully in the United States and Canada since approximately 1975 and is now one of the most trusted flat roofing systems used in the industry today. Modified Bitumen can withstand harsh exposure and extreme temperatures.
Metal roofing is still a very popular option in the commercial roofing industry because of its longevity and durability. In addition, it’s super lightweight which makes it easy to install and repair. Metal roofs are environmentally friendly and available in many styles and colors. They are often more aesthetically pleasing than other commercial roofing styles, making it a beautiful option.
