Metal Roofing and its Many Benefits
In this awesome article you'll find...
In the area of Ohio where I live, we are surrounded by many small German villages that were originally settled back in the early to mid 1800’s.
As you drive through them, you see that many of the homes still have their original metal roofs, and if they have been maintained these roofs provide the same level of protection well over a hundred years later.
The technology has obviously changed over the years, but those homes are proof as to why an increasing number of homeowners are choosing metal to protect their homes.
The lifetime of protection, durability, and other benefits make it an ideal residential roofing solution.
Here I wish to outline the different options you and other homeowners have when choosing a metal roof.
Like I said before, the technology has changed significantly over the years.
Metal is no longer confined to looking like the vertical seam panels you have seen on countless pole barns, but metal now creates the most beautiful roofing systems available. The types of metal roofing we will cover here are agricultural panel, standing seam, stone-coated steel, and press-formed shingles.
Agricultural Panel roofing systems are the products many of us have traditionally associated with metal roofing.
Most barns are roofed using this product because it is low cost, relatively durable, and optimum performance is usually not required.
Agricultural panels are manufactured using roll forming equipment and are given the look of vertical seams, but rather than having a true seam, the panels are overlapped and fastened by screwing through the face of the panels into the roof deck or rafters.
These roofing systems are sufficient for many agricultural and industrial applications, but as you can imagine the exposed screws will eventually leak.
For this reason, I do not recommend for this system be used for residential applications.
Standing Seam roofing systems have the same vertical look as agricultural panels, but the panels are installed with a true seam and concealed fastener.
There are countless versions of these panels, all different panel widths, seam heights, methods of fastening, and types of seams.
Commercial buildings usually use panels between 18″ and 24″ wide; standing seams that are designed for residential use are usually about 12″ wide.
Seam heights can range anywhere from 1.25″ and 2″. The quality of these systems varies depending on the method of fastening, type of seam, and paint system.
The lower quality panels will usually be coated with a polyester paint system, as opposed to the higher quality panels will use PVDF based paint.
Much of the industry has stopped using polyester paints in roofing application due to its issues with fading and chalking when exposed to the elements.
Stone-Coated Steel roofing was invented in the middle of the 20th century hoping to provide greater protection for traditional steel roofing systems.
The coating of bitumen and stone is similar to the coating used on today’s asphalt and composition shingles.
The coating comes in a variety of colors on a variety of profiles, creating a very attractive roof system.
The steel itself is very durable and in most applications can adequately protect your home, but unfortunately the coating suffers the same downfalls when applied to steel as when it’s applied to traditional asphalt and fiberglass.
Granule loss, streaking, staining, fading, and organic growth all diminish the roofing systems beauty after a period of time.
This is the only type of metal roofing not also made in aluminum; the gauge of aluminum necessary to support the weight of the coating is not cost effective.
Metal shingles are the fastest growing and most diverse segment of the metal roofing industry. Kaiser Aluminum and Alcoa Building Products were among the first companies to begin manufacturing press-formed metal shingles in the 1950’s; they are no longer players in the industry but their products are still being manufactured today.
Utilizing modern press technology, steel and aluminum can be made to look like traditional wood shakes, architectural shingles, slate, and tile roofing products, while still providing the benefits of metal.
The majority of the shingle products utilize PVDF paint systems-the best paint systems available.
The quality between products is differentiated by the intricacy of the panel, the quality of accessories, the locks, and the fastening method.
Benefits of Metal Roofing
Replacing your roof is an especially hard decision considering how many solutions are available and the magnitude of the decision-a failed roof would not end well!
I truly believe that a metal roofing system is the best roofing solution for most homes.
I hope you continue reading to learn about the main benefits of metal roofing and that the information helps you in your decision.
Each year, 80% of the roofs in the United States are reroofed using traditional asphalt or composition shingles. These products can only be expected to last a maximum of 12-15 years before jeopardizing your home and belongs.
These materials are prone to blowing off, curling, and cracking-all of which will inevitably cause leaks. These symptoms along with granule loss, organic growth, streaking, and staining all can diminish the beauty of your home as well.
Metal is by far the most durable roofing system available today. Its inherent strength, engineered systems, and specialized coatings protect your home from the elements and withstand the test of time. Metal is the most popular in the areas of the country where weather is most severe.
Homeowners along the gulf coast under the constant threat of hail and hurricanes, those in mountain areas facing snow and ice, and those living in areas prone to wildfires, have long known metal to be the best product to protect their homes.
Many metal roofing systems achieve the highest attainable Class IV Hail Rating and Class A Fire Rating and are warranted to withstand hurricane strength winds.
The best products are painted using PVDF based paint systems; these systems are warranted for 40 years to never fade, chalk, chip, or crack.
Over recent years we have all seen our energy costs rise dramatically; and with seemingly no end in sight, most of us are looking for ways to decrease our energy use. Many homeowners don’t realize that their roof is a key area where improvements could significantly decrease their home’s energy usage.
In most areas of the country, the energy used to cool our homes during the summer months is by far our peak energy use throughout the year.
Traditional asphalt and composition roofs only compound the problem by absorbing more heat into your home rather than reflecting it. Metal roofing systems are the most energy efficient systems available today and can decrease your energy costs by up to 25%.
Most systems are coated using reflective pigments that prevent the sun’s heat from infiltrating your home.
Many systems are engineered to also include above sheathing ventilation.
This air space between the roofing system and roof deck acts as a thermal break, just like in thermal-paned windows, and prevents any absorbed heat from reaching your attic or living space.
For most homeowners, myself included, these key benefits are for naught if the product does not improve the look of my home.
Many people associate metal roofing with the rusted standing seam on the old farmhouse.
That is a look some homeowners are looking for and is still available, but the technology has advanced significantly over the last forty years.
Metal roofing systems can now be formed to emulate traditional shakes, shingles, slates, and tiles in a variety of color and paint systems to best match your home.
The possibilities are endless for your roof to become another focal point of your home.
I hope this article provided you with valuable information about the different types of metal roofing available today.
When it comes time to reroof your home, I encourage you to look at metal roofing and see if it is the right decision for you and your home.
