Metal roofs offer many benefits over asphalt roofs: they are longer-lasting, naturally fire-resistant, and more energy-efficient. If you've chosen to install a residential metal roof, you're already sold on the benefits but may have a few questions about what to expect. Here's everything you need to know about installing metal roofs.
How Long Does it Take to Install Metal Roof?
In many locations, roofing work requires a permit. It can take two to four weeks to get a building permit. If your existing roof is old, there may be building code issues to address as part of the metal roof installation. Bringing the roof up to code can affect the cost, complexity, and time frame of the work.
According to the Metal Roofing Alliance, it takes a three-man crew anywhere from two to five hours to install 100 square feet of a metal roof. Divide the square footage of your roof by 100, then divide this figure by two to get a low estimate for the time frame. Divide the square footage by 100, then by five to get an idea of the upper range of the time frame for roof installation.
Challenges With Installing Metal Roofs
If your roof is not even, the underlying dips may need correction before the metal roof can be installed. Roofs that have multiple peaks and valleys add complexity to the job. Roofs with different planes, which are common in homes that have additions where the roofline is higher or lower than the main house, also take longer.
Weather can pose challenges with a metal roof installation, too. Since metal roofs become slippery in rain, roofers may need to pause your project if the weather is bad. While it's not impossible to install new metal roofs in winter, the shorter days and harsh winter weather tend to make metal roofing installation take longer.
The roofing contractor should provide you with a proposed time frame when they deliver the estimate. Always go through the estimate carefully to make sure you understand the scope and time frame of the work.
After the residential metal roof is installed, the roofing contractor should provide you with two warranties–one for manufacturing and the other for workmanship. They should also inform you of any maintenance instructions. This allows you to keep your new roof in great shape, so you can enjoy all the benefits offered by metal roofs.
