Coatings For Metal Roof Maintenance

Prior to the application of maintenance coatings, all required repairs should be completed. Initial repairs should be attempted at fasteners, seams and laps. There are a number of products available for repairs in these areas. Fasteners are typically waterproofed with sealants or compounds. Seams and laps can be waterproofed with a combination of fabric, such as polyester, applied in a flashing compound, such as high-solids acrylics.

Once the repairs are completed, preparation of the metal surface is required. The metal surface should be thoroughly power-washed. Rust and corrosion should be treated with a rust inhibiter after all loose rust is scrapped from the surface. When the preparation is completed, the metal coating should be applied in accordance with the manufacturers latest printed specifications in reference to application rates and requirements.

Most coatings used for metal roof maintenance are acrylic-elastomer-based reflective coatings. These coatings are available in high-solids formulations and can be VOC-compliant, with some manufacturers offering waterborne products. They are available in a variety of colors. Lighter colors are preferable for reflective ability. The application rate and number of coatings determines the type of warranty offered. Warranties range from one to 10 years.

Finally, lets looks at a few types of mechanically seamed metal roofing panels.

A mechanically seamed metal roofing panel is a type of metal roofing that has to be crimped or folded together after the metal roofing is laid. Each panel is crimped, creating a water tight seam between the metal roofing sheets. The major advantage of this type of metal roofing is its ability to be used in low slope applications like steel buildings or on other types of structures where the roof pitch is below a 3 /12. Common mechanically seamed metal roofing profiles include the 2, 138T, 238T mechanical and the trapezoidal panel. These metal roofing panels are most often found on steel buildings in commercial or industrial applications.

As you may have learned there are many different types of metal roofs, each with a specific use and application. That is really where metal roofing preforms, when the right type of metal roof isused in the right roofing application.

Install Lock Strips At The Rakes And Eaves

After your old roof is torn off, the starter lock strips are ready to be installed. Lock strips are what hold your standing seam metal panels to your roof edges and keep them from flapping in the wind or strong storms.

The lock strips will be installed at the eaves and rakes . Your lock strips will be made out of the same color and gauge as your metal panels.

Concealed Vs Exposed Fastener Metal Roof

Did you know? Corrugated panels are an exposed fastener metal roofing system. This means that screws are used to penetrate the face of the panel and attach it to the roof deck, leaving the heads of the screws exposed to the environment.

In addition to the fact that these exposed fasteners dont look particularly attractive, they also make your roof susceptible to leaks. Thats right, this particular metal roof can leak, because due to thermal expansion and contraction of the panels the screws get loose over time, and water can seep through.

They are also susceptible to rust and corrosion. To combat this problem, you will need to periodically replace the old screws and dried up rubber washers with new ones that can be tight once again.

Many homeowners mistakenly think that corrugated metal panels are just a more budget friendly version of standing seam, because they look a little similar. Nothing can be further from the truth!

R-panels dont provide the same durability, longevity or energy efficiency as true standing seam metal. They last only about 20 years, because they are made from a lower grade G60 galvanized steel. This is not much longer than the service life of regular asphalt shingles. Ultimately, you get what you pay for, so you need to decide which product best suits your needs and wallet.

Tear Off Your Old Roof

Before your new metal roof can be installed, your old roofing materials need to be torn off to get to a clean deck. What this means is that your roofing contractor will go section by section removing old roofing materials and tearing off your old shingles from the roofs decking.

Starting on the end furthest away from the dump trailer, theyll start using special tear-off forks to tear-off your old roof by sections. While one crew is going from section to section tearing off, another crew is making sure the torn off materials end up in the dump trailer or the tarped landing zone in your yard.

The tear-off process is crucial to the replacement process. To learn more about what this looks like, read this article on what a roof tear off is and how a contractor does it.

Advantages Of Metal Roofs

Metal roofs offer many benefits, including:

  • Longevity. Metal roofs can last 40-70 years, depending on the material. Traditional asphalt roofing materials have an estimated life expectancy of roughly 12-20 years.
  • Durability. If installed correctly, some metal roofs can sustain wind gusts up to 140 miles per hour, will not corrode or crack and may be impact-resistant . In addition, metal roofs don’t need the periodic costly maintenance that other roofing materials often require. However, they should be inspected periodically to make sure no repairs are required.
  • Safety. Metal roofs will not spark and ignite into flames during a wildfire or lightning strike.
  • Energy efficiency. Metal roofs reflect the suns UV and infrared light rays that contribute to roof surface radiant heat, which can result in a 10-25% reduction in cooling costs.
  • Environmentally friendly. Metal roofs not only have 25-95% recycled content, depending on the material used, but are also 100% recyclable at the end of their life as a roof. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream up to 20 billion pounds per year.

How To Choose The Right Metal For Your Roof

As you can see, there are a lot of options when it comes to metal roofing. To help narrow down your choices, we recommend considering the following:

  • What is your roof budget?

Metal roofing materials come in a very wide price range. If you are looking to be as cost-effective as possible, then a corrugated metal roof is an affordable solution. On the other hand, if cost is not a concern, consider a copper or zinc standing seam roofing.

  • What is your desired roof appearance?

Each material we discussed has its own unique look and style. Which one is best for you depends on your personal preference.

  • How long do you want your roof to last?

If you are looking for a metal roof with a traditional look, metal shingles will blend in nicely with the rest of your neighborhood. If you are looking for a striking appearance, copper has a beautiful appearance that will stand out. If you are looking for a modern look, standing seam is very popular for its contemporary aesthetic.

  • Is your roof near the coast?

You cant go wrong with any type of metal roofing when it comes to longevity. While they all have long life expectancies, installing a standing seam roof in zinc or copper roof can potentially last over a century. This will ensure that you never have to worry about installing another roof on your home again. However, even a corrugated metal roof can last up to 40 plus years.

  • Do you plan on installing the roof yourself or hiring a professional?
