Homeowners like the idea of buying just one more roof in their lifetime rather than potentially several. Metal roofs outperform shingles in hail and other severe weather events. In addition, they are designed and installed with fastening clips or slotted screw holes that allow thermal movement of metal with temperature changes without breaking over time, according to Classic Metal Roofing Systems President Todd E. This means that, in any climate, metal roofs have an average lifespan of 50 to 70 years, compared to 20 to 25 years for asphalt shingles.
In a properly installed metal roof, penetrations flash with corresponding metal. Whether you're putting a roof on a new home or your existing roof requires a total renovation, there are many materials available. But no matter what style of roof you have, metal roofs can be an attractive option due to their longevity, minimal maintenance, and energy efficiency. Material options include steel (galvanized, galvalume, or weather resistant), aluminum, copper, zinc, and tin.
Product types are vertical joints, preformed panels and granular coated panels. Style options allow you to have the look of shingles, slate, tile, milkshake, or vertical panels. Ensure your metal roofing product is tested, labeled, and listed with a testing organization, such as UL, FM Approvals, or Intertek, to meet rigorous wind, fire, and impact rating requirements. Also remember that installation may vary based on geographical location, manufacturer guidelines and, as a result of local building code requirements.
While metal roofs cost more upfront, this cost is offset by their longer life expectancy and durability. Metal roofs can last 60 years or more, with little or no maintenance required. Many roofing suppliers offer a 50-year warranty for metal roofs because they can withstand the elements and are resistant to mold, mildew, and insects. There is little or no difference in the environmental impacts caused by manufacturing metal roofing products versus asphalt shingle materials.
But they do come with a 30-year paint warranty that covers the protective layer of the metal panels. Unfortunately, oil canning is an inherent feature of almost every metal roof or wall installation, so it is not normally a cause for rejection of a system. More labor: The metal roof is a precision installation that is much less tolerant than the installation of a tile roof. Damage is easier: Shingles, especially 3-tab shingles, are much more easily damaged than metal roofs, especially during extreme weather conditions such as wind, hail and snow.
More warranty coverage: Tile roofs can come with a number of warranty offers from both the manufacturer and the contractor. Metal roofs come in large flat sheets and fold lengthwise into several different pattern categories, including corrugated metals and flat seam metal roofs. Homes with roofs made of asphalt shingles tend to sell for a little less than their points of comparison to metal roofs, but the age and quality of maintenance of a shingle roof home will have a greater impact on the resale value of the home than the choice of material in most cases. But now there are a variety of options that deserve consideration, especially metal, the second most popular roofing material thanks to its durability, longevity and a wide choice of styles.
Foot traffic: The ability to walk or put weight on the shingle roof is another reason shingles are easier for installers. On a metal roof, rubber tube boots are often covered with metal to match the roof, not only for aesthetic reasons, but also to protect the soft rubber from the sun's harmful rays. Energy efficiency: In addition to the environmental benefits of metal roofs, it also has energy efficiency advantages. Insurance Drawbacks: While there are benefits of insurance for metal roofs, there is also the potential for drawbacks.
This has caused homeowners to begin comparing the most commonly used asphalt tile roof to the metal roof. . .
