Not a real zip code.
Manufacturers in the United States use ‘gauge’ to express the thickness of metal roof panels. 22-gauge is the thickest while 29-gauge is the thinnest.
It’s important for you, as a homeowner, to know about the gauge/thickness of a metal roof, so you can select the best one for yourself. If you call Legacy Service, you’ll also have an expert opinion to help guide you through the process. Your options include 22, 24, 26, and 29. Continue reading to learn more about the pros, cons, and average prices of each.
When it comes to metal roofing gauges, thicker typically means that the cost will be higher. Some people may believe that thicker is always better, but whether it needs that added strength actually depends on the type of building construction as well as its location.
Homeowners choose 22 for metal roofing because:
Since it’s the thickest type, 22 tends to be the most expensive.
People choose 24 because:
It’s another expensive option due to its thickness in inches.
Property owners choose 26 because:
It’s not as heavy as 22 and 24, so it tends to cost less, but it’s also more expensive than 29.
Homeowners choose 29 because:
It tends to be the least expensive option in regards to metal roofing thickness.
Not a real zip code.
If you’re wondering how thick or what the differences between gauge numbers are in terms of inches, check out the gauge conversion chart below:
Although thicker panels are stronger, the importance of this extra strength is not always necessary. It depends on the type of building construction, the location of the building, and the customer’s priorities.
You should choose thicker panels if you have a post-frame building or a pole barn, which is an open-framed structure that’s used for barns, warehouses, and garages. In many cases, post frames lack structural sheathing, so the roof panels will need to span between the supporting purlins or trusses. Lighter-gauge panels, like 22-, 24-, and 26-gauge sheeting, will remain more structurally sound for years to come.
Most homes have a layer of plywood or sheathing covered by a weather-resistant barrier. Metal panels are attached to the sheathing to keep it dry. Since they don’t have a structural role, a 29-gauge panel would be more than adequate for most homes. So, if you live in an area that doesn’t often face harsh weather conditions, our recommendation is to choose a thinner type of panel. However, if you live in an area that experiences hailstorms throughout the year, you might be better off with a thicker panel to prevent dents.
Metal roofing gauges can be a complicated topic, so we get asked tons of questions by people who are considering metal roofs for their homes. The questions below are some of the ones that are most frequently asked by customers. If you’re wondering about anything else, make sure you give us a call today to schedule a free consultation!
It depends on where you live, but most homes in the United States that have metal roofs use 29-gauge panels. 29-gauge panels are the thinnest, so they tend to be the cheapest for homeowners. Houses don’t typically need thicker panels, so unless you live in an area that gets plenty of hailstorms throughout the year, your best bet would probably be 29-gauge.
The gauge of metal roofing you should use depends on your needs. Where you’re located, your building’s structure, your area’s climate, and more are all factors that will affect your decision when selecting the thickness of your roofing panels. For help determining which one would be best for you, whether you’re using standing seam, corrugated metal roofing, or another type, please contact us today. We’ll schedule a free consultation with one of our techs, who will go over everything you need.
When it comes to 24 vs. 26, 24-gauge is the thicker metal. Measuring gauge metal panels can be confusing because the lower the number is, the thicker the metal is. For our recommendation about which thickness would work best with your building, please feel free to contact us at any time to schedule an appointment with one of our techs.
When it comes to 26 vs. 29, 26-gauge is the thicker metal. Most homes in residential areas use 29-gauge metal panels. The weight of 29-gauge metal roofing may differ, though, depending on the type of metal that you choose. For instance, stainless steel will have a difference in inches than carbon steel.
You can find the thickness of your sheet metal by using a measuring tape and a simple conversion technique. First, use the tape measure to find its thickness in millimeters. This helps get the most accurate measurement. Second, multiply the number of millimeters by 0.03937. If your original measurement was 40 millimeters, the new one would be 1.5748 in inches.
It’s time to get started determining the right size gauge for your metal panels. At Legacy Service, we have decades of experience in the home exterior industry, including but not limited to metal roofing installation and replacement.
