Which type of coating is best for your existing roof system?

Once you determine the function of a roof coating, you must also consider the type of roof system you have that is going to be coated. Roof coating suppliers and manufacturers (like Conklin) generally offer two types of coatings: all-purpose, which are suitable for a range of substrates, and application-specific which tailored to one type or a limited range of substrates.

It is important to know that different substrates require different roof coatings. For example, it is more difficult for coatings to adhere to hard, smooth, chemically-inert surfaces, and much easier on rough, irregular, chemically-active surfaces.

Roof coating adhesion to a particular substrate improves when the installer applies a primer or base coat. Manufacturers like Conklin recommend very specific base coats (or primers) to match a specific top coat with a specific substrate. The installing roofing contractor should use only the base coat or primer specified by the coating manufacturer.

Coating primers and base coats for built-up roofs offer some very good examples. Manufacturers have designed products specifically to work on these surfaces - they work well on these often-hot surfaces by bonding to the asphalt and preventing it from bleeding into the white topcoat.

Enhancing the sustainability of a coated roof requires re-coating periodically to extend its service life. Most roof coatings are field-applied, and success depends on real-world conditions as well as the skill of the installer. To ensure proper curing, an experienced roofing contractor should pay careful attention to consistent application and changing weather conditions.

If you are considering a roof coating for your home or commercial building, make sure to ask the contractor why they are specifying the coating(s) being quoted and if that particular material is best suited for your roof.

Infrared-reflective architectural metal cool roofing

Infrared-reflective pigments are being incorporated into architectural metal roofing products to allow them to achieve higher reflectivity values, even in darker colors such as black and brown.

The improved reflectivity (for example, black changes from 0.07 with normal pigments to 0.32 with infrared-reflective pigments) can mean a much cooler surface temperature and greater energy savings for the building, allowing building owners and managers to select a sustainable roof without sacrificing aesthetic color choices.

To get 1 point for Sustainable Sites Credit 7.2: Heat Island Effect, the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) green building rating system specifies Energy Star requirements, adding a 0.9 emissivity standard.

For steep-sloped roofs, those with a rise-to-run ratio of 3:12 or greater, a 0.25 initial solar reflectance is required. In most cases, coated metal roofs can easily surpass the reflectivity requirement, and in some cases they can achieve 0.9 emissivity. More often they only achieve an emissivity of 0.85, thereby eliminating them from achieving the LEED point. For low-sloped roofs, those below 3:12, and flat roofs, the LEED reflectivity requirement is raised to 0.65, and the 0.9 emissivity standard is the same.

The Cool Metal Roofing Coalition, an organization comprised of metal industry trade associations, is providing commentary and data to USGBC requesting consideration for a reduction of the emissivity standard to around 0.7, contending that in addition to metal roofing’s energy efficiency when the reflective pigments are incorporated into a system’s design, metal’s long term ability to retain its reflective properties and a low life-cycle cost justify reducing the standard. The 0.9 standard “restricts a building owner’s ability to apply a suitable, long-term roof,” says Greg Crawford, executive director of the Coalition. The emissivity standard of 0.9 “is somewhat arbitrary,” says Andre Desjarlais, program manager for the Building Envelope research program at Oak Ridge National Laboratory, a supporting member of the Coalition. The 0.9 standard “is not defensible, but neither is eliminating emissivity altogether. We’re searching for middle ground.”

How to install a metal roof restoration coating system [+ video]

Watch as Elmer's Roofing Service, a professional Conklin roofing contractor, installs a metal restoration coating system on the rusted metal roof of the All Brands Appliances building in Neenah, Wisconsin.

The roof area is 190 squares. The job was started in the beginning of October of 2010 in Wisconsin, which is somewhat pushing it temperature-wise for a roof coating installation (to find out why, please contact Elmer).

The crew begins by pressure-washing the roof with a cleaning agent, then they install the fabric-reinforced primer over the corrugated metal panels. Then they base coat the horizontal and vertical seams of the panels and seal all the fasteners with caulk. Finally, the crew installed the white reflective top coat.

Elmer also gives you a behind-the-scenes look at the equipment they are using to give you a sense of what is involved with installing metal roof restoration systems (including a gas-powered Graco 733 pump which is hooked up to the drum on the truck which is filled with the Conklin roof coating material, and more).

Conklin foam & coatings repair over metal roof of Boys & Girls Club [+ video]

After a mechanical room fire at the Boys & Girls Club of Pekin, Illinois, one section of the metal roof had collapsed, and the existing foam was blistered from the fire.

Conklin roofing contractors worked quickly to remove the damaged section (including the metal itself), re-install new metal roof panels, spray on new foam, then install Conklin Roofing Systems base coat and white reflective top coat.

Installing a metal restoration roof coating systems vs. re-roofing [+video]

All metal roof owners eventually face problems such as rust, ultraviolet deterioration, photo-oxidizing, and a variety of weather-related damages. Instead of replacing your wearing metal roof, consider that a quality roof coating can keep your existing metal roof safe and secure for years to come.  

Roof leaks can damage more than just the contents of your building. They can weaken the walls and ceilings - jeopardizing the entire structure - as well as ruin insulation, causing your heating and cooling costs to soar. Instead of chasing and patching leaks or even re-roofing, metal roof restoration likely is a viable alternative well worth looking in to.

Restoration coating systems greatly extend the life of your existing metal roof at a fraction of the cost of replacement. They form a strong, protective barrier to prevent rust from forming on steel surfaces. Even where rust has a strong foothold, special anti-corrosion contents act to inhibit further spread of the oxidation process, and heat stress is reduced with the high reflectivity of the coating material.

The preparation for applying coatings over metal is actually fairly minimal. First, any loose scale, peeling paint, and rust are removed. Then the necessary metal repairs are made to prevent further deterioration. Flashings, curbs and other projections are repaired and reinforced, and finally all dirt and debris are removed and the entire surface is cleaned, often by pressure washing with water. A primer is applied before the application of the complete waterproofing system and final top coat.

Because they reflect up to 80% of the sun's ultra-violet rays, metal roof restoration coatings help reduce roof expansion and contraction, and prevent premature deterioration by providing a sacrificial layer to the elements, which helps to increase the servicable life of your metal roof. During summer months the high reflectivity helps to lower your cooling costs, and during winter months reduces the amount of heat emitted at night, ultimately reducing your heating costs.

Since little or no roof membrane is removed during restoration, interruption of building activity is minimized and the reuse of the existing roof not only saves tear-off and disposal costs, but contributes to the reduction of roofing-related landfill waste, which is estimated to be 25% of all landfill content in the United States.

When your metal roof ultimately becomes a rustly, leaky problem for the occupants of your home or commercial building, consider getting a quote from a professional roofing contractor who specializes in metal roof restoration coatings for a more affordable, more energy efficient, more environmentally friendly, more sustainable, and faster-to-install alternative to re-roofing.
