Is a Roof Restoration Worth It?

metal roof panels in need of repair

What does roof restoration mean?

If you own or manage a commercial structure, Why get a roof restoration instead of a new roof? There are several reasons that roof restoration is the better choice, which we’ll discuss in this piece as we answer common questions. Right now, we’ll give you two reasons that roof restoration is a better option:

  1. Save Money
  2. Reduce waste materials in landfill

The basic definition of restoration is the process of restoring something by taking the broken or deteriorated item and make it like new. Like restoring an old car or old home. When we’re talking about What is a roof restoration, it is the act of adding a coating to the existing roof that is structurally sound.  Commercial roof restoration is done by using a highly-engineered coating product that will restore the existing roof deck. By coating an existing roof that is made from BUR, EPDM, MOD-BIT, PVC, or TPO, the roof’s lifespan is expanded for another few years.

Which is better between Roof restoration vs replacement? We mentioned two reasons earlier, but let’s recap this topic and provide you five reasons that roof restoration may be the better solution over roof replacement for a commercial structure 

  1. Save Money: A commercial size building is not cheap to maintain and when it comes to having a  complete roof replacement, it is expensive! A roof restoration will save money because the existing roof does not have to be removed. That means less labor. Depending where the building is located and what type of roofing system is chosen, the average cost for a new roof can be has as high as $22 per square foot, or more. Roof restoration for the same building size and location can cost between $6 per square foot to $9 per square foot.
  2. Roof Restoration Extends Life: A commercial roof has a typical life span of twenty years when maintenance, repairs, and upkeep are done as recommended and required. A roof restoration can add up to another 15 years of life before a new roof is needed. This allows the building owner to defer complete replacement and plan for a new roof expenditure in their capital budget.
  3. Sustainability: As we all become more aware of our surroundings and things we can do that sustain our earth, a roof restoration eliminates adding to the already growing mound of waste in our landfills.  Each year, the roofing industry adds millions of tons to the already overflowing landfills, but with a roof restoration, the existing roof isn’t removed, simply recoated. Additionally, the building owner may be eligible for Energy Star or LEED tax credits for roof restoration that makes their building more energy efficient. What business owner doesn’t want to save on taxes?! 
  4. Speaking of Tax Benefits: A roof replacement is filed on the company’s tax records as a capital expense whereas a roof restoration is listed as a maintenance expense. The maintenance listing isn’t taxed as much as a roof replacement and the replacement is depreciated. Roof expenses for commercial structures hare on a 39 year schedule for depreciation and when you have a 20 average lifespan, why not get the most from the roof as you can? 
  5. Catastrophic Loss Prevented: A deteriorating roof is a problem in the waiting. They don’t just disappear or heal themselves – they sit there and get worse and worse. The more time you ignore a deteriorating roof, the bigger the damage is getting, which is going to end up costing you more, like a completely new roof. Ignoring possible roof problems is putting your business, your employees, and others at risk. 

What is involved in a roof restoration?

For a roof restoration to be done correctly, the existing roof needs to be thorough cleaned of all debris.  Patching any obvious issues and allow that patching method to cure and dry.  Then a commercial roof coating is applied, allowed to cure and dry. Some roof coating recommend or require a second coating, which is applied after the first coating has completely dried. Once done, your commercial roofing will have another ten to fifteen years of life added. 

How long do roof coatings last? 

When applied as instructed, including the thorough cleaning and any patching done, a roof coating can last up to 15 years, maybe 20 if the climate isn’t too harsh.  This all requires regular inspections that include cleaning and repairs if needed. 

What are the signs of a bad roof?

A commercial roof is complex and can be expensive. There are many different components to a commercial roof that need attention in order to keep the roof in good condition. That is where the recommended regular inspections are important. During these inspections, the things that you need to pay particular attention to are: 

  • Ponding Water
  • Moisture or Water Stains on Ceiling
  • Rot
  • Mildew and Mold
  • Wear and Tear from Age, Climate, Environment
  • Signs of Neglect

Can you redo your own roof?

You can if you have the manpower and time available to spare. Your maintenance team can learn how to do a roof restoration from videos found online and following the instructions on the roof restoration materials chosen. 

However, if your maintenance team does the roof restoration, you don’t have any backup of guarantee or warranty that a professional roofing contractor would provide. So, if there is a problem, your maintenance team will need to find the issue and make repairs as needed, with the possibility of never finding it. A professional roofing contractor will have the experience to look for problems and secure the situation properly. Call (931) 220-1728 today for roof restoration in Nashville, TN.

How Do You Waterproof a Flat Roof?

How do you waterproof a flat roof?

If you are a building manager, you know very well how difficult it is to keep water off a flat roof. Because drainage on flat roofs is so poor, a common problem is ponding, in which water collects on the roof. This damages the roof in a variety of ways and often leads to leaks. To prevent these problems, building managers constantly look for ways to waterproof their roofs. Applying a flat roof coating for ponding water is one of the best ways to waterproof a roof. Coatings like silicone and acrylic are applied directly over the roof. These coatings are seamless and seal up small holes to stop leaks and help the roof shed water better. They also prevent new leaks from occurring.

Most coatings will work on most flat roofing materials including tar and gravel and modified bitumen roofs. Many also work on metal and concrete roofs. In addition to commercial buildings, coatings are also applied on mobile home roofs as well as on the rooftops of certain campers and RVs. If you want to waterproof your flat roof and need a flat roof coating in Nashville, TN, you can always count on the professionals at Yoder's Commercial Roofing for exceptional service. To schedule a service appointment, all you need to do is call (931) 220-1728.

What is the best coating for a flat roof?

There are several flat roof coating options available, though most coatings are either silicone, acrylic, or polyurea. While all have their value, silicone coatings are fast becoming the preferred coatings for flat roofs. This might leave you wondering “Is silicone roof coating worth it?” Why are people choosing silicone over other coatings? 

One main reason people are choosing silicone over others is its effectiveness as a waterproofing agent. The coatings are not water-based so they don’t absorb moisture, and water will not pond on the roof when the coating is applied. It’s also valued because it remains intact rather than shedding away like other coatings. When you get a silicone coating, you’ll require less of it and get the same or more benefits than other coatings.

What is the best way to repair a leaking flat roof?
Although applying a roof coating will help prevent new leaks from developing, if your flat roof is already leaking it will need to be repaired before a coating is added. For materials like TPO or PVC, you’ll need a professional to make the repairs, but for EPDM and other common flat roofing materials, some leaks can be a DIY job.

  • Repair small holes and punctures using rubber sealant applied directly to the damaged area. Alternatively, you can get patches for EPDM roofing. Tar will work on a tar-and-gravel roof. The tar is covered with mesh reinforcement and a layer of gravel.
  • Repair blisters by cutting through the bubble end to end, drying the area underneath, and applying either sealant, tar, or patch over it. 
  • Repair a larger tear or hole using the same methods, only using more sealant and larger patches.

What is elastomeric roof coating?

Another roof coating type for flat roofs is elastomeric coating. This is a liquid coating that can be applied to most flat roofs, including single-ply membrane roofs, as well as metal and concrete roofs. Like other roof coatings, elastomeric coatings create a seamless layer over the roof that helps prevent ponding and leaks. They are also wind resistant. These coatings, like others, also have reflective properties that protect your roof from UV radiation, improving overall energy efficiency, and saving you money on utility bills. With an elastomeric coating applied, you’ll extend your roof’s lifespan by 20 years.

Flat roof coating colors

Although traditionally most roof coatings are white, some manufacturers are producing coatings of many colors. Some popular colors include green, light tan, brown, black, and red. Manufacturers have begun providing different colored coatings so people can better match the coatings to the rest of the building’s color and design. While adding a color coating might be aesthetically pleasing, you might lose some of the UV protection gained with a white coating. Check with the manufacturer for details on a particular coating’s effectiveness against UV radiation.

If you want to add a splash of color, it’s best to use a colored roof coating rather than adding paint to a white coating. Paints and coatings are different materials and paints do not adhere well to them. They also may affect the coating’s other properties.

Is a metal roof worth it?

What is the best color for a metal roof?

Metal roofing on commercial structures, and even though most are above eye level and you’d never know it. In fact, most people on the street wouldn’t give two thoughts to the roofing material of a commercial building. Like a homeowner, a commercial building homeowner, an important metal roof detail is the color.

Metal roof or not, color is important to a commercial building’s appearance, and fortunately, there is a wide choice of metal roofing colors, finishes, and textures, today for commercial structures.  From a modern, natural tone to rustic finishes, the designs are plenty to fit any type of architecture style. 

Matte finishes are a popular choice today for metal roofing, going with the trend of aged metal with a classic style. A Galvalume finish is natural with a real feel of contrasting beauty when paired with glossy paint or wood siding. 

Today, metal roofing contractors offering colors that are cool to work with sustainable buildings. A metal roof that reflects sunlight during the summer and not absorb heat is important in areas of the country where summer can be sizzling.  Besides galvalume, and galvanized, there are twenty or more gauges of colors today that are reflective and solar reflective.

Keeping in mind that lighter colors reflect the UV rays and darker colors absorb. So, if your building is in an area where there is more hot weather, going with a lighter color is recommended. Light color choices include:

  • Beige
  • Gray
  • Light Bronze
  • Peach
  • White

For commercial buildings where the climate is colder, best color choices are:

  • Black
  • Brown
  • Dark Greens
  • Dark Blues

Does a metal roof need furring strips?

Yes, especially when metal roofing is being installed over an existing roof, regardless of what type of roof coating was applied last.  Furring strips decrease condensation building up, which can damage the roofing and should be placed twenty-four inches apart.

The spaces in between the wood furring strips should have a layer of ridged insulation installed prior to the metal roofing. The insulation will help decrease the condensation and provide extra insulation too. Insulation layered under the metal roofing panels is critical to mitigate thermal bridging and provides a sound barrier. 

Is underlayment required for metal roofing?

Metal roofing is durable and will provide a long lifespan for a commercial building when it has been correctly fabricated and installed.  Underlayment is an important part of a metal roofing and can be an asphalt-soaked felt, self-adhering membrane, or synthetic sheets. Metal roof to wall flashing is just as important and must be installed correctly to provide the protection intended.

When looking for a metal roofing contractor, Google a search “metal roof installers near me” and they can discuss which type of underlayment is the best for your building based on the climate and size of the building. 

Do you need gutters with a metal roof?

If the commercial building has a flat roof, the drainage system is unique than a commercial structure with a sloped roof. A gutter system is recommended on a commercial building with metal roofing to keep the water from flowing out and away from the building, allowing space for walking next to the building without being drenched.

There are several factors to consider when deciding to install a gutter system on your commercial building metal roofing. A gutter system for a commercial structure isn’t the same as it for residential properties, for starters, commercial structure gutter system are box gutter shaped and larger than that of a residential gutter system, because the roof is larger, thus more water flowing off the roof.

How do you stop condensation on a metal roof?

Traditionally, metal roofing has been insulated during install with furring strips to prevent condensation. The insulation keeps the metal roofing panels from reaching a dew point temperature that creates condensation.

If a metal roofing wasn’t installed with furring strips and insulation, there is a patent membrane product on the market that can be added afterwards. They attach this membrane to the underside of the metal roofing panels. This membrane has a rubber backing with felt-like material and will trap and hold moisture that typically results in condensation forming.

Other choices in commercial structure roofing are typical for a flat roof and include EDPM, PVC, and TPO. For a commercial building with a pitched roof, metal roofing is ideal. It can be made to look as antique and classic or as clean and modern style as the building’s architectural style.

Regardless what color of metal roofing you choose, making sure that regular inspection and proper maintenance and upkeep are followed through. This can be done by staff maintenance crew on a monthly basis, but once a year, a professional inspection by a commercial roofing contractor is recommended. For your metal roofing in Nashville, TN, call (931) 220-1728 today.

Is it recommended to insulate under metal roof?

When you have a metal roof, you’ve invested in a roofing system that is extremely durable, requires minimal care but has maximum longevity. At the same time, two problems can occur if your roof isn’t properly insulated: you’ll experience a lot of noise, especially in severe weather like hail, and your building’s overall energy efficiency will be reduced. In fact, many building managers ensure the metal roofing is well insulated just for these reasons. While in some industrial settings noise may not be a problem, almost all commercial enterprises want their buildings to be more energy efficient. Insulation will always save you money on utility expenses. For this reason alone, when you have a commercial metal roof in Nashville, TN, Yoder's Commercial Roofing recommends insulating it. Find out how we can help with your metal roof by calling (931) 220-1728.

What do you put under a metal roof?

If you’ve chosen to install a metal roof on your commercial building, you’ve made a wise choice. But, to avoid serious problems in the future, you want to make sure your new metal roof is properly installed, and what goes under the roof is just as important as the metal on top. When you’re talking through the roofing project with roofer’s make sure they give you a rundown of all the materials they are installing. A good underlayment for a metal roof will vary by location and climate but some of the components you’ll want to consider will include insulation for noise reduction and heat transfer, a water barrier, vapor retarder, and air barrier. If those materials aren’t present or aren’t installed correctly your roof could suffer serious problems like leakage or moisture entrapment.

Commercial metal roof types

If you are considering installing a metal roof for your commercial building, you’ll have several types to choose from, each valuable for different types of buildings. Some of the most common metal roofing types include:

  • Corrugated galvanized steel
  • Sheets of metal tile
  • Copper
  • Aluminum
  • Stone-coated steel
  • Stainless steel
  • Tin
  • Lead

You’ll also have options such as standing seam or corrugated styles. Standing seam metal styles are common and work with almost any material. The type of metal you choose will depend on several aspects including weather, climate, and cost. Aluminum, for instance, is highly resistant to corrosion, and is often chosen in coastal regions because of the high salt content in the air. Other materials like copper tend to be very expensive to install, whereas stainless steel or galvanized steel as well as tin cost much less. 

What is the best color for a metal roof?

In the past there wasn’t much choice when it came to the color of your metal roof. It was, well, the color of metal. Now, manufacturing processes can produce metals of all shades. What’s the best color for your metal roof? There is no catch-all answer. Every situation will be different, but much will depend on the purpose of the roof, location of the building, climate, as well as aesthetic considerations. Energy efficiency often plays a big role in color choice, as lighter colors will reflect heat better than darker colors. If you live in a warmer climate, the lighter the material, the more heat it will reflect. The material doesn’t have to be white, however, for it to be efficient. Even a lighter shade of a darker color like blue or green might be a better choice in such a climate.

What is the minimum roof pitch for metal roof?

The pitch of a metal roof will depend on the type of panels you are using. When looking at pitch, you have to determine the roof’s slope to get the right ratio for the type of panel you are using. The ratio is determined by dividing the vertical rise, or pitch, by every 12 inches of horizontal span. Common slope ratios are 3:12, ½:12, and ¼:12. Your roofing contractor will understand the ratio that is best for the type of panels you’re using.

Can you put a metal roof on a low pitch roof?

While metal roofs tend to have a higher pitch or vertical rise, it is possible to place a certain type of metal roof on a low-pitch roof. The only type of metal roof that can be used for low-pitch roof is structural panel.

Commercial metal roof installation

If you are wondering how to install commercial metal roofing, the installation processes will vary depending on the type of metal you’re using and whether the fasteners are exposed or hidden. While both types of panels, for instance, are attached with special screws, hidden fastener panels also have to be attached together by fastening the cleats of each panel together before the screws are put in.
