I know you had a 30-year warranty, but—after 15 years—those shingles simply must be replaced. Anyone can call a roofer, but why not take a shot at making your own shingles? But first you need a formulation—the recipe—and I’ve got just the one for you. And while we’re at it, let’s compare shingle manufacturing to metal roofing manufacturing.
Prescriptive Requirements vs. Performance-Based Testing in the Construction Market
Sometimes your doctor writes a prescription for your ailment, and sometimes your doctor wants to run some tests first. The first example is a prescriptive approach (do this and you will be okay), whereas the second example is a performance-based approach to solving your problem (take some meaningful measurements and then determine what to do). The same two options are also used in the metal building industry.

We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour, sit quietly, and we will control all that you see and hear.

About 75% of the North American coil coating industry is dedicated to building products. Since the lifetime of these products is measured in decades, as opposed to merely years, the weathering performance of the coatings used for this market is critical. Understanding how coatings perform, therefore, is essential. There are many approaches to studying weathering performance, and one of the more interesting techniques to accelerate the weathering process involves the devices described in these two ASTM standards:
As an association, the National Coil Coating Association (NCCA) has the ability to speak with one voice on any number of issues. The association is dedicated to the coil coating process: cleaning a metal substrate (aluminum, hot-dipped galvanized steel, etc.), chemically treating the substrate to enhance corrosion resistance and paint adhesion, priming the strip with a corrosion-resistant primer, and topcoating the strip with any number of materials designed to provide aesthetics and durability to the coil-coated metals used in the construction products, transportation, appliance, and HVAC markets.

It goes by many names: prepainted metal, coil coated metal, prefinished metal. Each of these descriptions refers to the product of a coil coating line, sometimes called a continuous coil line (CCL). Prepainted metal is commonly used as a coated product in construction applications (metal walls and roofs are two examples), as well as appliances, HVAC units (air conditioners, furnaces, etc.), rainware products (gutters, downspouts, flashing, etc.), and many others. Prepainted metal is the product; a CCL is the application process used to produce prepainted metal.
When it comes to making a home energy-efficient, the choice of roof can have a far-reaching impact on the overall sustainability of a structure. The right kind of roof makes a home’s entire energy infrastructure operate more efficiently, staying naturally warm in winter and cool in summer. This cuts down the need to augment temperature through heating or air conditioning and reduces reliance on the earth’s natural resources. Continue reading
