Metal Roofing Installation and Repair

The cost of a metal roof varies depending on several factors, including the size and slope of your roof, the style or color of panels, and the complexity of the installation. Labor is a major part of the investment, since proper installation is key to performance, appearance, and warranty coverage. While the upfront costs of a metal roof is usually higher than other roofing options, many homeowners find that it pays off over time. Metal roofing often lasts several decades with minimal upkeep, which reduces the need for frequent replacements. It can also improve energy efficiency by reflecting heat and lowering cooling costs. Some insurance companies even offer discounts to homes with premium metal roofing. When comparing costs, it’s important to look at the initial price, potential savings on energy and insurance, and the increase in resale value a professionally installed metal roof can provide.

Because we offer many financing options, homeowners can often choose the roof they want without having to delay the installation.

Shingles are the most common roofing option because they are widely available and come in a range of price points. They can be a good choice for homeowners who want flexibility in style and budget. Metal roofing, on the other hand, is rapidly growing in popularity because of its strength, fire resistance, and long service life. A shingle roof may need replacement sooner, while a metal roof is built to last much longer with less upkeep. Metal is also highly reflective, which can help with energy efficiency, while shingles, especially darker colors, tend to absorb more heat. Shingles are usually easier to repair if damaged, while metal provides stronger overall protection against severe weather. The best choice depends on how long you plan to stay in your home, your goals for energy savings, and whether you prefer lower upfront cost or longer-term value.

The most common concerns homeowners raise are noise during heavy rain, higher upfront cost, and potential for denting. Noise is usually controlled by proper underlayment and attic insulation, which reduce the sound significantly. Cost can be higher than economy asphalt shingles, but many homeowners choose metal for its long lifespan and lower maintenance. Dents are usually only an issue with thinner gauge metals or if the roof is struck by large hail or falling limbs. Another concern can be expansion and contraction of panels, sometimes called “oil canning,” with temperature changes. Professional installation minimizes this with proper fastening systems. Overall, most of these problems can be addressed by choosing the right products and an experienced metal roofing contractor.

Yes, a metal roof can sometimes be installed directly over existing shingles, saving money and the time of tearing off the old roof. However, it depends on the condition of the roof decking and underlayment. Without removing the old shingles, it is difficult — and sometimes impossible — to know if there are problems underneath. That’s why we generally recommend a full tear-off. Installing a roof over damaged decking increases the risk of moisture issues, wind damage, and voided warranties from suppliers.

Since this question often depends on the specific house, we recommend reviewing our detailed guide. An in-person inspection is the best way to confirm whether your home is a good fit for installing metal over shingles.

A properly installed metal roof can last 40 to 70 years, depending on the type of metal and the environment. Steel and aluminum are the most common materials, and with protective coatings, they can withstand decades of weather. Copper and zinc can last even longer, sometimes over a century. Compared to shingles, which may need replacement every 15–25 years, metal roofing offers a much longer service life. Maintenance is also minimal, usually limited to occasional inspections, gutter cleaning, and checking fasteners. For homeowners looking for a roof they will likely never need to replace, metal is one of the longest-lasting options available. Premium brands of metal roofing, like ProVia, even offer lifetime material warranties to the original homeowner, making it a “forever roof” for many families.

Metal roofing is usually made from steel or aluminum. Aluminum roofs are lightweight and resistant to salt corrosion, making them favored in coastal areas. Steel roofs, popular among homeowners in East Tennessee, are strong, long lasting, and coated with protective finishes like zinc (galvanized) or a zinc-aluminum mix (galvalume) to resist rust. Copper and zinc are also used, though they are higher-end options. Panels come in different profiles, such as standing seam or ribbed panels, and are painted with durable finishes to protect the surface and provide a wide range of color choices. Homeowners can select from many styles, some of which mimic the look of shingles, tile, or slate while still offering the strength of metal.

Residential metal roofing comes in thicknesses ranging from 24 gauge (thicker) to 29 gauge (thinner), with 26 gauge being the most common in East Tennessee.

Generally, no. While metal can theoretically interfere with radio frequencies, cell signals enter your home through walls and windows, not just the roof.

Keep in mind, if you live in a remote area like the Smoky Mountains with very weak existing service, we recommend checking your signal strength inside your property before picking metal over shingle roofing.
