7 Common Questions About Commercial Metal Roofs

There are a lot of good reasons to consider a metal roof for new or existing commercial buildings. They deliver a long service life. Metal roofs conserve energy and provide energy savings of up to 40%. They can be recycled. And, they can even improve your property value.

Here are seven questions we’re commonly asked about commercial metal roofs.

1.      What is the average lifespan of a metal roof?

On average, a metal roof can be expected to last 40 years. Compare that to 23 years for asphalt and 20 years for a single-ply roof. The more attention you pay to proper maintenance of your metal roof, the better your chances of hitting that life expectancy.

2.      How do you repair rust on a galvanized metal roof?

Unlimited Commercial Roofing can repair rusted or leaking metal roofs to provide decades of leak-free, waterproof protection. This is an overview of our process, which involves using :

Step 1. Start by priming your metal roof to neutralize existing rust and prevent future rusting.

Step 2. Caulk all fastener heads and weak spots in your metal roof.

Step 3. Waterproof all seams.

Step 4. Apply a reflective top coat to protect your metal roof from leaks for many years to come.

3.      How much does it cost to reseal/restore a commercial metal roof?

Depending on the source, the average cost nationally to have a contractor reseal a metal roofing system is $845 to $942 per square foot. Keep in mind that the sealant type, metal roof condition, and even location can affect costs. Restoring a roof can save thousands of dollars, however, versus roof replacement.

4.      Does my roof need to be replaced if I have a leak?

Most leaks in commercial buildings with a metal roofing system result from separating seams, openings in flashing, oxidation (aka rust), fasteners backing out, or issues arising from storm damage or even improper installation. These problems can be repaired relatively easily without the need for roof replacement. It’s important to make sure you have a quality installation from the get-go to avoid leaks down the road.

5.      How much is a metal roof?

The cost for a metal roof is a lot like asking the cost of a car. There are a lot of factors that can affect the bottom line price. What kind of metal roof are you looking for? What type of metal material would you like to use? How big is your roof? What gauge metal do you want to use? What kind of customizations will need to be made? That said, anticipate anywhere from $7.00 to $12.00 per square foot. Here’s a handy calculator that might help: https://www.roofingcalc.com/.

6.      Is ice melt safe for metal roofs?

In short, you shouldn’t have to worry about using products like ice melt on your metal roof. A metal roofing system actually tends to shed snow more rapidly than some other types of commercial roofing materials, especially if it is not completely flat. The main reason for this is because metal roofs have a reasonably smooth surface that actually helps shed the snow. They also have reflective properties that help utilize the sun’s energy to aid in snow and ice melt.

7.      Can I walk on a metal roof?

You bet! Of course, that doesn’t mean you shouldn’t take precautions. Wear clean, soft-soled shoes. Avoid dropping heavy tools that could dent or scratch your metal roof. And learn to walk in the right spots by consulting with a commercial roofing expert. Really, you shouldn’t have to worry about getting up on your roof yourself—a professional roofing contractor like us here at Unlimited Commercial Roofing can take care of any issues with leaks or damage without you having to climb a ladder.
