Metal roofings are becoming popular in homes, farms, ranches, and businesses due to their high endurance, ability to resist all weather and long lifespan, making them a worthy investment. But, choosing the right gauge (thickness) metal roofing for barns is equally important as it has a direct impact on the roof’s strength, longevity, and resistance against harsh weather. But how do you select the right gauge, what are the available options in the market, and which one should you opt for? Let’s have a look at the answers to all these intriguing questions.
What Is Metal Roofing Gauge?
A metal roofing gauge refers to the thickness of the metal panels used on the roof. The gauge number is inversely related to the thickness, i.e., the higher the gauge number, the thinner the metal panels would be.
For example, a 24-gauge metal sheet is thicker than a 26-gauge, which is thicker than a 29-gauge.
A thicker metal panel provides:
- Enhanced resistance to impact
- Better resistance against strong winds
- Bears heavy snow load
- Ideal for extreme weather regions
Meanwhile, a thinner metal panel is economical and ideal for moderate-weather regions. Here are quick comparisons between various gauges that are used in metal roof barn installation:
| Gauge | Thickness [in inches] | Est. Cost [per sq. ft.] |
| 22 | 0.0299 [heavy] | $3+ |
| 24 | 0.0239 | – |
| 26 | 0.0187 | $1.75+ |
| 29 | 0.0142 [lightest] | $1.0+ |
26 Gauge Metal Barn Roofing
- Thickness: 0.0187 inches
- Features: It is thicker and stronger with higher resistance to harsh weather like strong winds and heavy snowfall. It offers better durability and is less prone to denting.
- Uses: 26ga metal roofing panels are generally seen in areas with extreme weather, commercial structures, and long-term projects to ensure durability throughout their lifespan.
| Pros | Cons |
| Greater strength and durabilityBetter protection against severe weatherLonger lifespan | Higher upfront costHeavier, requiring stronger support structures |
29 Gauge Metal Barn Roofing
- Thickness: 0.0142 inches
- Features: It is slightly thinner and lighter in weight. It offers ample protection in moderate weather zones and is easy to handle and install.
- Uses: 29ga metal roof panels are suitable for residential homes, carports, and barns in regions with milder climates.
| Pros | Cons |
| Lower costEasier and quicker to installAdequate for less severe weather conditions | Less durable than 26-gaugeMore prone to denting and damage from extreme weatherShorter lifespan |
Comparing 29 & 26 Gauge Metal Roofing For Barns
- Cost: A 29ga panel is more affordable, which makes it a popular choice for budget-conscious home & farm owners. A 26ga panel, on the other hand, requires a high initial investment but offers a better long-term value as it needs fewer repairs and touch-ups.
- Durability: In a moderate climate, 29-gauge panels are suitable, and lastly. It is common in residential homes and small businesses but less durable overall. A 26-gauge panel is known for its superior durability and weather resistance. It is ideal for homes, farms, and ranches in regions prone to strong winds, heavy snow, and hail storms.
- Installation: A 29ga panel is lightweight and easy to handle, which simplifies the installation process and reduces labor costs. Due to its heavier weight, a 26-gauge metal roof requires stronger supporting structures, which adds to installation costs and may increase complexity, but eventually, it provides a stronger roof.
- Roof Framing: For a 29-gauge panel, purlin spacing must be about 2 to 4 ft. apart, while for the 26-gauge metal panel, purlin spacing must be 4 to 5 ft. apart. This is because 26-gauge panels are thicker and can handle larger spans without sagging or bending under load.
Less Known Facts About Metal Barn Roof
- 26-gauge metal panels are industry-standard for metal buildings, along with 14-gauge steel frames.
- Do you know that being heavier in weight, a 26-gauge roof panel can withstand higher speed winds and bear impact from debris better than 29-gauge panels?
- Insurance companies may offer you a lower premium for a dwelling unit or metal barn with a 26-gauge roof due to its higher durability.
- 26-gauge metal roofing has better thermal performance, providing better insulation and reducing energy costs.
- A 26ga metal panel can be more effective in reducing noise due to rain and hail.
Making The Right Choice: Which Metal Roofing For Barn Should You Choose?
Factors to consider when choosing a metal barn roof and its gauge:
- Climate: Your local climate plays a significant role in determining which gauge you should choose. For regions with severe weather, 26 gauge is recommended as it offers higher durability and resilience.
- Budget: A thicker gauge comes with a higher initial cost but gives better long-term value than a thinner gauge, which is affordable.
- Building Type: Consider the type of building you want to install. Is it for residential, agricultural, or business needs? What size is it? Each sector has its own unique needs and set of regulations imposed.
- Future Maintenance: A thicker gauge generally requires fewer repairs and maintenance, so they are virtually maintenance-free in the long run, reducing costs and effort.
- Consult Professional: You can consult a professional metal building dealer to learn more about frame and roof panel gauges and know which one works best for your needs.
- Local Building Regulations: Make sure that your choice of metal roofing gauge complies with the local building codes and zoning laws for safety and structural integrity.
It is important to strike the balance between initial costs & long-term benefits. Investing in thicker metal panels for the barn’s roof will provide better security, durability, and lower upkeep needs. In contrast, a lighter panel will be easy to handle, cost-effective, and suitable for smaller metal buildings in mild-weather regions.
