Metal Roof Warranties – Don’t be fooled by the years!

In the metal roofing industry it’s amazing that there is such as wide range of warranties! It’s actually become a bit of marketing game and one that confuses the contractors, architects and for the most part those metal roofing sales teams.  Here’s a simple question;  If we were to tell you that we’d supply you a product that comes with a 45-year SMP warranty vs. a product that would come with a 35-year PVDF warranty…which product would you choose? The 45 year product of course!  What you don’t know is that the SMP performance criteria is not as good as the PVDF system and more is actually less.  Let me breakdown the differences for you:Surf MallPaint Warranties cover three main items; Film Integrity, Chalk and Fade/Color Change. Paint doesn’t rust so the substrate is not included in your PAINT warranty (although there is a perforation warranty on Galvalume even when painted). Here’s a breakdown of each coverage item:

  • Film Integrity: The paint will not crack, flake of PEEL for the life of the warranty.
  • Chalk: This is a number system that allows for a certain amount of chalk. Chalk is the residue resulting from Weathering Decomposition of the paint films.  Visual Ratings are assigned according to ASTM D659 and ratings range from 10-0 with 10 being the best.
  • Fade/Color Change: is the change in the paint film color and appearance due to degradation from UV Radiation in Sunlight…this is also known as Color Weathering.   Ever hear of a Delta E or NBS unit?  This is the measuring unit for color color change per ASTMD2244.  Values range from 0 to infinity where 0 is the best (No color change).  This is measured on both Vertical and Non-Vertical applications.  Metal Roofs are typically Non-Vertical.

So back to that 45-year warranty.  This is actually the number of FILM INTEGRITY years that your warranty covers however if you read each section (Color change and Chalk) you will find that there is only a 30-year warranty on both chalk and color change.  So in reality, you have a 45-year warranty stating that your paint will not fall of your roof but only 30-year coverage on aesthetics.  The coverage is replacement materials only and does not include labor.

I wanted to give you an idea of color change using the photo below. On the left is the unexposed product and on the right is the allowable color change during the term of the warranty.   As you can see, PVDF (Kynar500(R) or Hylar5000(R)) resin systems perform much better in the color change department than the SMP system.  The 35-year warranty covers you for 35 years whereas the 45 year warranty actually covers you for 30 years.

kynar vs smpThe bottom line;  understand what’s covered and what is not and don’t be fooled by the # of years.  More is actually less in this case you’ll often make the wrong decision without understanding all of the facts. You may be thinking who cares…in 30 to 35 years I am not going to care what color my roof is….the key is you are not getting the value for what you think you are paying for.  Also keep in mind, warranties are only as good as the companies that stand behind them and most of them are non-transferable from owner to owner.

It also requires a Drexel Metals Certified Installer to install your roof using approved Drexel Metal products from the roof deck up!


Drexel Metals meets with GPIC – Greater Philadelphia Innovation Cluster for Energy Efficient Buildings


Drexel Metals met today with the Greater Philadelphia Innovation Cluster (GPIC) for Energy Efficient Buildings regarding exploring the opportunity to work together to create awareness about the importance of creating and monitoring performance of the building envelope.  The GPIC (  received $129 million from the Federal Government’s Energy Regional Innovation Cluster (E-RIC) Initiative. The award included $122 million from the U.S. DOE to create an Energy Innovation Hub to develop innovative energy efficient building technologies, designs and systems.

For more information about GPIC

The goals of the GPIC are to improve energy efficiency and reduce carbon emissions of new and existing buildings, and to stimulate private investment and quality job creation.

The GPIC will focus on full spectrum retrofit of existing average size commercial and multi-family residential buildings.  The program goal is to transform the commercial building retrofit and new construction processes into a systems-delivery industry, and demonstrate building operational energy savings of 50% by 2013-2015 in a scalable, repeatable and cost effective manner across a broad building stock, while preserving workplace quality.

A comprehensive research, development and deployment program will be performed that simultaneously addresses the maturation of integrated design and system technologies, exploration of new business models and public policies that accelerate the technology adoption, and the creation of robust workforce development paths. Commercial building stock turns over slowly, and major overhauls are relatively rare. Major retrofit demonstrations are emerging, like the Empire State Building, but they are rare point solutions and achieve less than 40% energy improvement and are not generally scalable to the less than 100,000 square foot building stock.

Scalable 50% energy reduction retrofits – DOE’s building energy goal is to reduce the annual energy use of buildings by 80% in the year 2050.  New approaches to design/build/operate building system technologies, new business models,  public policies, and workforce development paths are required.  An interim goal of demonstrating 50% energy efficiency improvement was selected to stretch beyond applying conventional solutions which have been demonstrated in select retrofit examples in the ~30% efficiency improvement range.  This 50% energy efficiency goal requires that the technical, policy and workforce solutions sets are scalable to at least 50% of today’s commercial building stock.  This goal demands rethinking every technical approach and solution set as well as adopting new business value propositions, public policy positions and workforce development processes.

Drexel Metals Inc. is extremely excited about the opportunity to work with the GPIC to research and expand our energy efficient metal roofing assemblies and to work to expand our product portfolio by adding proven technologies to maximize building envelope performance.

The meaning of the Drexel Metals Rising Sun Logo

The story of our logo! Hope you enjoy!

In October 2008, Drexel Metals’ CEO, Rob Waite and President, Brian Partyka, brought a customer on a tour of Independence Hall in Philadelphia.

Independence Hall is an incredibly inspiring place to visit. While we know the outcome of our Founding Fathers’ courageous efforts, they had no guarantee for success. The price of failure was not the loss of a business, but the loss of a nation. When the Founding Fathers stated their commitment to the cause in the Declaration of Independence in July 1776, “We mutually pledge to each other our Lives, our Fortunes and our sacred Honor”, it was not just for literary affect!

From the summer of 1776 through the summer of 1789 when in the same building our Constitution was signed, our country had been forged in the crucible of a Revolution that we all have benefited greatly from for over two and a quarter centuries and counting.

On the final day of the Constitutional convention, as the last delegates were signing the document, Benjamin Franklin pointed toward the sun on the back of the Convention president’s chair and Franklin said, “I have often … in the course of the session … looked at that sun behind the President without being able to tell whether it was rising or setting. But now at length I have the happiness to know it is a rising and not a setting sun.”

Upon hearing this during their tour, Rob and Brian looked at each other and knew they had to incorporate a rising sun in Drexel Metals’ new logo.

In 2008 Drexel Metals had been accelerating the development of their “Metal Roofing On Demand” business model while navigating the turbulent and tumultuous economic environment.  At the time businesses either changed to survive the economic conditions or they stuck their heads in the sand hoping the economy would improve before it was too late for them. Rob and Brian made immediate decisions exemplifying their tenacity to succeed.

While Drexel Metals had been developing it’s “Metal Roofing On Demand” business model for a number of years, it became time to commit all of it’s resources to the full implementation of this business model. It’s “Metal Roofing On Demand” model is built around the Drexel Metals Association of Regional Manufacturers (DM-ARM), where it’s members enjoy a significant reduction in the cost of standing seam metal roofing by declaring their independence from high cost, low service large fixed-in-place manufacturers. DM-ARM members are able to service their customers virtually on demand through the local production of fully engineered, warranted and backed Drexel Metal Roofing Systems.

In 2009 and 2010, the DM-ARM had record years. First quarter of 2011 results reveal that the DM-ARM is well on it’s way to breaking those records. We are happy to say that the sun is most definitely rising for the members of the Drexel Metals Association of Regional Manufacturers.

Drexel Metals LLC proves the importance of being able to backup their Metal Roofing performance!

We recently wrote a blog post about how some of our competition is willing to take the risk about their <29 SRI ratings which helps to qualify for LEED credit 7.2.  They should think twice!!! According to the USGBC is getting hit with a $ 100m civil lawsuit which alleges fraud, unfair competition, deceptive trade practices and simply false advertising!  See below;

Henry Gifford, owner of Gifford Fuel Saving and a public critic of the U.S. Green Building Council’s (USGBC) LEED certification program, has filed a class action lawsuit against the organization and its founders on behalf of “consumers, taxpayers, building design and construction professionals,” reports Shari Shapiro, an attorney and LEED Accredited Professional, Green Building Law Blog.

The $100-million lawsuit alleges fraud, unfair competition, deceptive trade practices, and false advertising, among other things, reports TreeHugger.

Gifford alleges that USGBC has falsely claimed that its rating system makes buildings save energy, and that building owners have spent more money to have their buildings certified, and professionals have gained worthless professional credentials, says Shapiro. Click here (PDF) to read the complaint.

Gifford uses his critique of a 2008 study from New Buildings Institute (NBI) and USGBC that looks at the actual energy performance of buildings certified under LEED for New Construction and Major Renovations (LEED-NC) to support his allegations, reports Building Green. While the NBI study finds that LEED buildings are, on average, 25 percent to 30 percent more efficient than the national average, Gifford’s own published analysis concludes that LEED buildings are, on average, 29 percent less efficient, according to the article.

Shapiro doesn’t expect the suit to survive class certification for several reasons. For example, she says as “a general proposition, taxpayers do not have standing to sue,” and “there is a commonality problem and a causation problem for the class–did the USGBC’s false statements cause the same type of harm to the same type of plaintiff. Indeed, did the false statements cause any harm at all to these plaintiffs.”

Shapiro raises other questions including: Is the USGBC engaging in intentional, fraudulent actions? Or was it a good organization seeking to benefit the world by promoting more ecologically friendly building practices?

Shapiro also notes that Gifford is not a LEED AP and does not appear to own any property certified LEED so USGBC’s actions have not harmed him or his career.

Gifford told Building Green that he has lost out of business because “owners are fixated on earning LEED points,” adding “unless you’re a LEED AP you’re not going to get work.” He also says he can prove that the buildings he has worked on saves energy.

According to a recent green building study nearly 93 percent of design and construction professionals continue to endorse green building despite the recession, although support for LEED certification slipped again in 2009, widening the gap between support for green construction and LEED certification

Understanding Rooftop Solar Systems and your Drexel Metal Roof System!

Solar Metal Roofing

As the Metal Roofing industry continues to further promote the use of integrated solar options, metal roofing installers may run into many challenges.

There are four steps that may help sell a solar roof system:

  1. Learn how the systems work and understand the terminology, such as solar efficiency, de-rates and thin film versus glass;
  2. Learn the financial model;
  3. Align your company with an electrical partner and roofing manufacturer
  4. Track results in real time…in other words…put your money where your mouth is!

Clients want solar to achieve a triple bot- tom line impact: people (societal benefit), planet (environmental benefit) and profit (financial benefit). The following basic information will help contractors, distributors and installers prepare for a successful solar roof presentation and installation.

First, identify what type of structure you are dealing with. Building factors to take into consideration include building height, roofing system, exposure (south/southwest is ideal) and shading potential. For electrical service, consider usage and voltage. Finally, consider cost of energy and possible incentives for utility considerations. A good re- source for this can be found online at www.

Solar energy is measured in watts. A kilo- watt equals 1,000 watts. Kilowatts are measured by the hour and expressed as kilowatt- hours (kWh), or 1,000 watts acting over a period of 1 hour. Finally, a megawatt is 1,000 kilowatts and a megawatt-hour is one mega- watt acting over a period of one hour.
The system size depends on how much roof area is available.

Here is an example of a simple approach when using 20 standing seam panels that are 20 feet in length and have a south/southwest exposure.
Each photovoltaic laminate thin-film panel produces 144 watts – 20 (x) 144 watts = 2,880 watts of DC power 2,880 watts divided by 1,000 = a 2.8-kilowatt system

Depending where your project is located, you will need to figure out your solar radiance, which is how much average solar energy production the system will achieve. As an example, the average solar radiance for eastern Pennsylvania is 4.4 hours. (2.8 kilowatts x 4.4 solar radiance multiplier) = 12,672 watts daily average or 12.6 kilowatts 12.6 kilowatts x 365 = 4,625 kilowatt annual energy production of DC power.
Solar systems are sold by direct current (DC) power. Incentives are calculated in DC, as well. To convert the DC to alternating current (AC), you need to use an invert- er, which needs to be sized properly to meet the system requirements. For the size above you would use a 2,800-watt inverter. BUILDING FACTORS TO TAKE INTO CONSIDERATION INCLUDE BUILDING HEIGHT, ROOFING SYSTEM, EXPOSURE (SOUTH/SOUTHWEST IS IDEAL) AND SHADING POTENTIAL.
Converting to AC energy production: A de-rate factor is calculated for wire loss and conversion loss going from DC to AC; 80 percent de-rate factors are commonly used. 2.8 kilowatts x 80 percent = 2.3 kilo- watts x 4.4 = 10.1 kilowatts AC production = 3,700 kilowatts of AC annual production.
When selling solar, the panel’s solar efficiency often is the subject of questions. Solar efficiency is a ratio of capacity versus space, not an efficiency of production or ability to produce electricity efficiently.
Solar efficiency is a power density ratio that’s calculated in a controlled lab; it’s ex- pressed as a percentage. On a sunny day when the sun’s rays shine through a clear atmosphere and perpendicular to the Earth’s surface (e.g. at noon on the equator on the equinox): Defined as 1,000 watts of sunlight per square meter of panel. Solar panel power efficiency ratings are almost always the power they would produce in these conditions when operating at a temperature of 25 C and at the maximum power voltage. For example, a solar panel that is 15 percent efficient takes in 150 watts per square meter.

Selling a solar roof system is 85 percent financial sale and 15 percent technical; the numbers have to add up and make sense. Here are a few questions you may encounter when discussing solar:

  • “What’s my return on investment in terms of years?” The answer to this will vary, based on region, installed cost per watt and available incentives.
  • “Will the appreciation in property value affect our tax assessment?” If a property owner installs an active solar energy system, the system will not be assessed on the current property. Any other improvements constructed to support the system—for example, a new patio or carport—are not included in the exclusion and will be assessed at current market value as of the lien date or date of completion of the new construction. When the property under- goes a change in ownership, however, the active solar energy system becomes assessable along with everything else on the property.
  • “What are the first-year utility savings, average monthly utility savings, average annual utility savings and 25-year utility savings?” You’ll need to know the system sizing and the annual energy consumption of the property. Will I be able to sell my power to the grid–also known as net metering? Net metering programs serve as an important incentive for consumer investment in renewable energy generation. Net metering enables customers to use their own generation to offset their consumption during a billing period by allowing their electric meters to turn backwards when they generate electricity in excess of their demand. Currently, net metering is offered in more than 35 states.

Be sure to align yourself with a good electrician, as well as a good solar supplier. A solar layout and permit package, which will be sup- plied by the solar roof manufacturer, is necessary. This will be used for the utility company, building inspectors and code officials. Be sure to make demands on your supplier to have a technical representative on the project site foryour first install, which is common practice.

Finally, be able to track the output in real time. Put your money where your design is and make sure your system can be monitored using a Web-based dashboard. The dashboard brings the system to life and you hook up the system through the inverter’s data monitoring card with an Internet connection. This gives the owners something to look at, send to their friends or put in the lobby of their building tracking every- thing from energy output daily, weekly and monthly to carbon offsets, and even barrels of oil and gallons of gas offset.

Solar roof systems are complex, but if you take the time to understand the basics it may lead you to your first install, thereby earning profit, expanding your business and helping the environment. For more information about Drexel Metals Solar Roof Systems visit our website or visit
