29 Gauge Metal Roofing
What is the cost of a steel roof? The cost of a metal roof will vary depending on the roofing panel width, thickness/gauge and the shape and pitch of your roof. An experienced metal roofing contractor can easily determine the right profile and gauge that will be best for your building. They will also be able to provide material and labor estimates. Check with a nearby roofing distributor or lumber yard for a qualified contractor in your area. < Back to top How long will steel roofs last? When installed and maintained properly, metal roofing can last as long as fifty years or more and still maintain its beauty, while other traditional shingle and shake roofs need replacing after an average of 10-15 years. < Back to top Do hot and cold temperatures affect a steel roof? Yes. Expansion and contraction should be taken into consideration when roofing with steel. A rule of thumb for ASCBP steel roofing is any panel exceeding 40 feet in length should have a system that allows for expansion and contraction (ie. clip). Skyline Roofing® and the Sterling Roof System® have clips available for long length applications. Contact an ASC BP representative for more information if your roof requires long length panels. < Back to top Will a steel roof rust? No. ASCBP steel roofs are coated with Zincalume®, a combination of 45% Zinc and 55% Aluminum that carries a 25 year anticorrosion warranty. This metallic coating is bonded to the steel at the factory and coated with our exclusive DuraTech®xl Paint system providing a lifetime of long-lasting color. The exception to this rule is our IronOx panel. This panel lacks a coating and is designed to rust for aesthetic effect. < Back to top How much does an ASCBP steel roof weigh? Metal Roofing in general is a very strong, yet lightweight material compared to other roofing products. The 26 gauge metal roofing products weigh between 0.90 – 1.00 lbs. per square foot. The 29 gauge products weigh between 0.60 – 0.65 lbs per square foot. < Back to top Will a steel roof make your house hot inside during the Summer? No. Just the opposite, with ASCBP’s “Cool Colors”, homes and attics will remain cooler longer compared to homes with conventional non-cool composition shingle roofing, reducing energy costs during the hot summers months. Our DuraTech®xl paint system is formulated with special pigments that reflect rays from the sun. An ASC BP metal roof in Cool Winter White can reflect as much as 70% of the sun’s rays, keeping your home cooler during hot summer days. A study by Oakridge National Laboratory showed that a “cool” white metal roof reduced energy bills in the summer by up to 40%. < Back to top How is a steel roof good for the environment? First steel is made from recycled material. About 25% to 30% of the steel used in an ASC BP metal roof is melted down from recycled steel. Unlike other roofing products, steel roofs can be recycled at the end of their useful life. Finally, steel roofs with Cool Colors can save your home up to 40% in summer cooling costs and steel roofs are highly emissive (they cool off quickly after the sun goes down) which can reduce air temperatures in urban cities. Combined, these benefits mean less dependence on energy resources and less general air pollution in your neighborhood. Steel roofing is considered a “green” product. < Back to top Does a steel roof make noise during a rainstorm? This is a very common myth about metal roofing. If the roof is installed over a solid substrate, the sound of the rain will be no different than any other roof. ASCBP recommends installing its roofs used in residential applications over an existing continuous rigid substrate such as plywood, wood decking or OSB. < Back to top Are ASCBP steel roofs Class "A" Fire Rated? ASCBP steel roofing is a ferrous, non combustible product as defined in the building code. Please consult your licensed roofing contractor or your local building department for the current code requirements in your area. < Back to top Does an existing roof need to be removed when installing a new steel roof? ASCBP steel roofs may be installed over other roofing materials however it is always recommended that the existing roofing material be removed so the roof sheathing and roof penetrations may be inspected for any damage or dry rot.
29 Gauge Metal Roofing
The 29, 26, and 24 metal roofing gauge is a measurement of the thickness of the metal, but it’s important to remember that the metal increases in thickness as the gauge numbers decrease. Union offers several gauge options for metal roofing. Listed in order from thinnest to thickest, they are: Utility metal roofing Econ 29 gauge metal roofing 29 gauge metal roofing 26 gauge metal roofing 24 gauge metal roofing
29 Gauge Metal Roofing
The gauge of the metal is a measurement of how thick it is. The smaller the number, the thicker the metal. 24 gauge metal (sometimes written “24ga”) is thicker than 29 gauge, which is the minimum recommended gauge for residential construction. Some roofs, such as Modular Press Formed Granular Coated roof, are only available in certain gauges (26 gauge in this case). 24 gauge is the recommended gauge for high wind areas. The gauge of the roof doesn’t affect the overall price much. The difference is usually a matter of around $100 per square. (A “square” in roofing is a 100 square foot area.)
29 Gauge Metal Roofing
2. Thickness affects price. Metal roofing is measured by the gauge. The lower the gauge number, the thicker the metal (I know it seems backward, but I didn’t invent the standard). The most common roof gauges are 29, 26, and 24. And 29-gauge is what the unscrupulous roof scammers are peddling at their “amazingly low price”. Now, to add some perspective: a soda can is a 37 gauge and a car hood is around a 20 gauge. Why would you buy a metal roof just slightly thicker than a Dr. Pepper can (with a bunch of screws sticking out of it)? And what makes anyone believe that 1.5” hail can damage the hood of a car, but not a metal roof made of a thinner gauge metal?
It’s important to note that 29 gauge metal roofing is the thinnest metal recommended for residential applications. Heavy gauge metal roofing, like our heavy duty 24 gauge metal roofing, is recommended for those areas with severe weather, high winds, or hail.
Metal roofing is becoming more and more popular as composition shingles rise in price. We believe metal is an excellent alternative. You can drive around your neighborhood and see metal roofs in many different types and installed on all types of homes. The key to the longevity of a metal roof is how the roof is installed. Is all the flashing installed properly? Eave metal edging, chimney and skylight flashing, and the vent pipes are the areas that take extra care and experience to do correctly. At Hartman Roofing we understand the cost associated with installing metal roofing and we make sure the metal roofing we install will give you years of worry-free service.
I have seen people ripped off by traveling workers offering a hail proof metal roof for the same price, or cheaper than their asphalt shingles. They will screw down these metal panels directly over the asphalt shingles, or over some batten boards that have been fastened over the shingles. And the reasoning behind otherwise intelligent homeowners convincing themselves that this is a good idea is: the price is “too good to pass up” and “metal roofs are hail resistant”. These days, since Oklahoma has the 2nd loosest consumer protection when it comes to the roofing industry, many “contractors” are broadening their horizons into alternative roofing materials, i.e. metal roofing. After all, how hard can it be to screw down some metal panels? They don’t bother to educate themselves first, or get certified with the products (especially in Oklahoma or Texas where they are not required to). The only way for a homeowner to protect their home is to know a few things about these metal roofs, before letting a novice metal installer butcher their roof. After all, the roof costs 10% of the home’s value and is supposed to keep the rain out of the other 90% of it.
There are instances where thicker gauges always earn their keep. The most common of these is the post-frame building, or pole barn: an open-framed structure used for barns, garages and warehouses. Post-frames generally lack structural sheathing, so the roof and wall panels must span between the supporting trusses or purlins. Because 22-, 24- or 26-gauge sheeting is thicker, and will therefore remain more structurally sound over a longer span than a 29-gauge, the building needs fewer supports, which saves money. For post-frame structures like this, it is important to consider the potential snow load your roof may need to support when choosing your metal panel gauge. Lighter-gauge (thicker) panels may save you from structural collapse in the winter months!
Despite this, thicker (lighter-gauge) panels can make sense for buildings in hail-prone areas, but not because of structural integrity. A 29-gauge metal panel can have the same impact-resistance rating from Underwriters’ Laboratory (UL) as a 26-gauge panel; the advantage of thicker metal panels in this case is that they are less prone to denting. If you live in a place like Cheyenne, Wyoming (the hail capital of North America) and are concerned about long-term appearance, thicker panels may be the better option for you.
