Why Textured Paint is changing the Metal Roofing Industry

Why Textured Paint is changing the Metal Roofing Industry

Textured paint or Crinkle paint as it is sometimes called, is making a real impact on the metal roofing industry. There are several reasons for this and we want to outline a few of them for you. Textured painted metal will not replace the smooth coated products that have been used for years, however is is a very good option to look at, and in many ways it is a better option.

What is Textured Painted metal?

Textured painted metal was actually discovered by accident in a lab several years ago. The lab technician added a special catalyst to the standard paint formula and discovered that as the paint dried, the additional catalyst caused the paint surface to texture / wrinkle. This technique was refined and tested in order to achieve the highest quality and performance.

What are the improvements of Textured Paint?MetalStandingSeamRoof.com-Standing-Seam-Metal-Roof-r2

• Less Glare, The textured paint really minimizes the glare that a metal roof can inherently have. This lends to a overall better appearance.

• Better scratch resistance, Because the surface of the metal textured, it will resist small scuffs and scratches.

• Better traction, If you have ever needed to walk on a metal roof, you are aware that depending on the conditions, it can be difficult to maintain traction. The textured surface greatly improves that traction. This is a benefit for both the installers and the homeowners.

• Hides under decking imperfections, Because of the reduced glare of the textured metal, any substrate imperfections will be less noticeable.

More Information

Textured Painted metal is a really good option for someone that wants the long life of a metal roof, but wants something that has a lower gloss.

Galvalume vs Galvanized

The difference between Galvalume, and Galvanized Steel

The difference between Galvalume, and Galvanized Steel

If you start looking into metal roofing, it won’t be long before you hear the term GALVALUME®.  So what is that , and how does it work?

What is Galvalume Steel

Galvalume was developed in 1972.  Essentially it is a 55% aluminum to 45% zinc alloy coated sheet steel.  This blend is what makes it different than Galvanized Steel  which is covered with a zinc-only coating. According to BIEC, the licensor, 120 million tons have been produced since 1972, and Steelroofing.com estimates 40 billion square feet of Galvalume steel has been used in roofing worldwide. With GALVALUME, the aluminum and zinc act together to resist corrosion and provide barrier protection on the roofing surface. Zinc alone would allow more rust to occur, while Aluminum alone does not stand up as well to hail and other damaging forces.

What is Galvanized Steel

Galvanized Sheet is carbon steel sheet coated with zinc on two sides by a continuous hot-dip process. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. One of the drawbacks of Galvanized is that if the Zinc coating is scratched off the steel, the Steel is left unprotected, and is subject to failure.

Galvalume vs. GalvanizedGalvalume vs Galvanized

While both products were developed to essentially sacrifice themselves to protect the steel sheeting they coat, the exposure comparison photo shows that Galvalume® performs (up to nine times) better in fighting corrosion as compared to Galvanized coating. While Galvalume® can initially show signs of corrosion faster than Galvanized, it has a sacrificial property that will prevent the corrosion from growing whereas once corrosion has started on a Galvanized panel, it can continue to corrode until panel integrity is lost. According to a study released by the Metal Construction and Zinc Aluminum Coaters associations, the longevity of a low-slope unpainted Galvalume® standing-seam roof is 60 years Additionally, primer and paint adhere better to Galvalume®-coated panels and they carry a 20-year limited warranty while galvanized panels do not, making them a smarter long-term investment for all building applications.

Conclusion

Another great feature of Galvalume Steel is that as the material is cut, the Zinc and Aluminum combine to prevent corrosion at any exposed edges. Galvalume Steel can be expected to provide at least TWICE the service life of traditional zinc-coatings of similar coating thickness under the same exposure conditions. This has been proven by actual exposure tests using flat coupon samples, conducted over 36 years in the U.S.A. and 15 years in Canada. These tests show that Galvalume has at least TWICE the service life versus Galvanized.

All of the Steel products that we use here at Classic Metals, are manufactured using Galvalume Steel. Feel free to contact us if you have any questions or comments.

Metal Roofing, What is the True Cost?

Metal Roofing, What is the True Cost?

What is the true cost of Metal Roofing, and how does it compare to asphalt shingles? That is a question that i hope to clarify. When it comes to making a major purchase, the tendency is to only base our purchase decision on the price of the item. Sometimes this can be OK, but often it leads to making a decision that will cost us far more in the future.

The average cost of replacing your roof with a dimensional asphalt shingle is around $260.00 per square. This would equate to $7,800.00 for the average ranch home. The frustrating part is knowing that in 20-25 years those very shingles will end up in a landfill.  In a 60 year span this home will need to have the roofing replaced 3 times. This could very easily reach a total of $25,000.00.

The average cost of installing a entry grade metal roof will be around $300.00 per square. This equates to $9,000.00 for the average ranch home. This Metal Roof will have no problem in lasting 60 years, and will do so for the total cost of the original purchase.           ( $9,000.00 )

Another factor to consider is the energy saving of a energy star Metal Roofingmetal in comparison to asphalt shingles. This fact alone would
provide a substantial savings over a 60 year period. Some recent study’s have shown a average potential savings of $300.00 per year, equaling $18,000.00 in 60 years. An additional fact to consider is the increase of value that your home will have with a Metal Roof. If you ever sell your home, the buyer will have peace of mind knowing that the roofing is the last thing that he needs to be concerned about.

In the 60 year example that we laid out, here is the true total Cost of the two roofing systems

Asphalt Roofing–$25,000.00

Metal Roofing–$ -9,000.00 ( a Total Savings of $34,000.00 )

What is the True Cost of Metal Roofing?  You can’t afford NOT to buy a Metal Roof.

Making Sense of your Energy Star Steel Roofing Questions

Classic Metals specializes in manufacturing metal roofing products, because of that we get asked about Energy Star roofing on a regular basis. This question originates from customers concern regarding what type of roofing qualifies for Energy Star, and what percentage of savings can be expected by using an Energy Star products. Because it seems hard to find good information that makes sense concerning this question, we wanted to explain a little bit about how Energy Star Steel Roofing works for our customers benefit.

What is Energy Star

In 1992 the EPA began the energy star program to help identify and promote energy efficiency and products homes and buildings nationwide. The goal was to raise consumer awareness about how many products can save them energy costs in the long run, and help the environment by cutting energy usage. Through its partnerships with 18,000 private and public sector organizations, ENERGY STAR delivers the technical information and tools that organizations and consumers need to choose energy-efficient solutions and best management practices. ENERGY STAR has successfully delivered energy and cost savings across the country, saving businesses, organizations, and consumers $24 billion in 2012 alone. Over the past two decades, ENERGY STAR has been a driving force behind the more widespread use of such technological innovations as efficient fluorescent lighting, power management systems for office equipment, and low standby energy use. Products bearing the ENERGY STAR labels are more energy efficient than standard products, thereby saving energy and money. In general, ENERGY STAR certified products including: appliances, HVAC equipment, office equipment, residential lighting, roofing, and even homes, reduce energy costs by at least 30 percent

How does a Roofing Product become Energy Star Rated

Roof products that meet or exceed solar reflectance, without compromising product quality and performance, qualify for the ENERGY STAR label. Manufacturers voluntarily sign an agreement with ENERGY STAR called a Partnership Agreement (PA) allowing them to place the ENERGY STAR label on the packaging of qualifying roof products. They can also use the label in product promotions and advertising for certified products.

How is Energy Star Roofing Rated

There are three tests that can be done on roofing to show how it is affected by the sun’s rays, and how much heat is absorbed.solar-reflectance

Solar Reflectivity ( SR ) is the measure of a certain roofing material’s ability to reflect solar energy, or sunlight from the roofing  surface. SR Value’s are numbered from 0-1.0. A value of 0 indicates that the surface absorbs all the solar energy, and a value of 1.0 indicates that the surface reflects all the solar energy. In order to meet the Energy Star requirements, the SR value for steep pitch roofing ( more than 2/12 pitch ) must exceed .25 SR. The SR test is the only test that is used for the Energy Star rating.

Emissivity ( EM )energytransfer

Emissivity is the roofing material’s ability to radiate absorbed heat, thus lowing the roofing temperature at a faster rate after the solar energy subsides. EM is not used for Energy Star ratings.

Solar Reflective Index ( SRI )

Solar Reflective Index is used for compliance with LEED requirements and is calculated according to ASTM E 1980 using the values of SR and EM. In other words it is the combination of the SR and EM tests, and is used for a overall view of how the roofing material preforms. In order to meet LEED requirements, the roofing material must have a SRI of .29 or greater for steep roofing ( more than 2/12 pitch ). The SRI test is not used for the Energy Star ratings.

How much can I expect to save with Energy Star roofing

Energy savings from installing ENERGY STAR certified roof products will depend on the geographic location and climate where it is installed, existing insulation levels in the building, the type of roof it replaces, the type of roof installed, and how well it is kept clean and maintained. In general, cooling energy savings can be as high as 50 percent. Additionally, a reflective roof can reduce peak cooling demand by 10 to 15 percent. As a result, building owners may be able to purchase smaller, less expensive HVAC systems. Below is a test that was done on a control home in 2000 using several different roofing materials. It is not hard to see how the savings can add up, especially when you consider that the lifespan of a metal roof is 60+ years.

 

Cooling performance at a control home Total kWh Savings kWh Save Percent Demand kW Savings kW Saved Percent
Standard dark shingles (control home) 17.03 0.00 0.0% 1.63 0.00 —-
White “Barrel” S_tile roof 15.29 1.74 10.2% 1.44 0.19 11.80%
Standard dark shingles, sealed attic, R_19 roof deck insulation 14.73 2.30 13.5% 1.63 0.01 0.30%
Terra cotta S_tile roof 16.02 1.01 5.9% 1.57 0.06 3.70%
White “Barrel” S_tile roof 13.32 3.71 21.8% 1.07 0.56 34.20%
White flat tile roof 13.20 3.83 22.5% 1.02 0.61 37.50%
White metal roof 12.03 5.00 29.4% 0.98 0.65 39.70%
