DIY Roofing Basics: How to Measure a Roof for Metal Panels

Wed, 09 Sep 2026 20:39:39 GMT

Measuring a roof for metal roofing does not have to be complicated. The goal is simply to determine how many panels you need and how long each panel should be .

Step 1: Measure the Roof Width

Measure the roof from eave to eave (side to side).

For example:

Roof width = 34 feet

Convert feet to inches:

34 ft × 12 = 408 inches

Step 2: Divide by the Panel Coverage Width

Each metal roofing profile has a coverage width , which is the amount of roof one panel actually covers after the seams overlap.

Common examples:

1" Mechanical Lock Standing Seam = 17" coverage

Corrugated Panel = 29" coverage

Mechanical Lock Example

408 in ÷ 17 in = 24 panels

Corrugated Example

408 in ÷ 29 in = 14.07

Always round up , so you would order 15 panels .

Step 3: Measure the Roof Length

Step 4: Calculate Total Linear Footage

Measure from the eave to the ridge (bottom edge to the top of the roof).

Example:

Roof length = 18 feet

Your panel length would be approximately 18 linear feet (plus any desired overhang).

Quick Formula

Multiply the number of panels by the panel length .

Mechanical Lock

24 panels × 18 ft = 432 linear feet

Corrugated

15 panels × 18 ft = 270 linear feet

This gives you the total amount of panel material needed.

Number of Panels

Roof Width (inches) ÷ Panel Coverage Width (inches)

Panel Length

Roof Length (top to bottom) = Panel Length

Total Linear Footage

Number of Panels × Roof Length

A Few DIY Tips

Measure each roof section separately if the roof has multiple planes.
Round up on panel counts to avoid coming up short.
Add a little extra material for waste, trimming, and future repairs .
Remember that coverage width is not the same as the actual panel width —always use the manufacturer’s stated coverage width when calculating panel quantities.

With just roof width, roof length, and panel coverage width , most homeowners can get a solid estimate for ordering metal roofing panels before starting a DIY roofing project.

Now, if you're roof is this basic, you're pretty lucky. Usually we have flashing features like valleys, irregular hips, gable roofs or other architechtural features that could make things tricky. Just remember to apply the same principles in sections. Still have questions? Josh can steer you in the right direction. Call us 970-975-1712

Board and Batten: Classic Style Meets Durability

Wed, 09 Sep 2026 20:25:56 GMT

Board and batten has been turning heads for generations. The clean vertical lines feel classic, but when the profile is made from metal, it brings a modern level of strength to the job.

That is what we call a good-looking upgrade.

Classic Style, Modern Material

Traditional board and batten siding is known for its wide panels and narrow raised battens. The vertical pattern adds height, dimension, and character without making the exterior feel too busy.

Metal board and batten keeps that familiar look while offering the durability today’s Colorado homes and buildings need.

Built for Colorado Conditions

Colorado weather does not take days off. Sun, wind, snow, and sudden temperature changes can put exterior materials to the test.

Metal board and batten provides:

Long-lasting performance
Lower maintenance than many traditional siding materials
Clean lines that complement modern and mountain architecture
A wide range of color options

It is a practical choice that still knows how to make an entrance.

More Than a Farmhouse Look

Board and batten may be a farmhouse favorite, but it is not limited to one design style. It works beautifully on mountain homes, cabins, commercial buildings, accent walls, gables, skirting, and full exterior applications.

Use it across the entire building or pair it with stone, wood, or horizontal siding for added contrast.

Fabricated With the Details in Mind

The best results start with accurate measurements, quality materials, and panels fabricated for the project.

At Gunnison Sheet Metal & Roll Forming, we help contractors and property owners find the right metal profiles, colors, and custom components to keep each project moving. Because when the details are right, installation gets a whole lot easier.

Shop Talk: When 1/8" Becomes Miles

Wed, 09 Sep 2026 20:21:40 GMT

If you've worked in construction, fabrication, or manufacturing long enough, you've probably heard someone say, "It's only off by a little" maybe followed by cross-eyed admission of "eye-balling" the measurement.

In reality, that tiny measurement can become the difference between a smooth installation and an entire day's worth of rework.

In this episode of Shop Talk , Tori and the team at Gunnison Sheet Metal & Roll Forming share one of those stories every contractor can relate to, where a seemingly minor measurement turned into a second shift, 96 new fascia pieces, and a valuable reminder that craftsmanship is often measured in fractions of an inch.

Sometimes the smallest details have the biggest impact.

In Custom Fabrication, Precision Isn't Optional

Unlike mass-produced building materials, every project we manufacture is built specifically for the job it's going on.

Each panel.

Each trim piece.

Each fascia.

Each measurement.

Everything is produced to match the unique dimensions of the project.

That means there's very little room for "close enough."

When you're fabricating custom metal, an error that's barely visible on a tape measure can multiply across dozens, or even hundreds, of pieces.

The Value of Local Manufacturing

One of the biggest advantages of working with a local manufacturer is the ability to respond quickly when adjustments are needed.

Because our panels and trim are manufactured right here in Gunnison, we can often produce replacement materials much faster than suppliers shipping products across the country.

That flexibility helps contractors keep projects moving while reducing costly delays.

It's another reason so many builders choose to work with a local fabrication partner.

Mistakes Happen. Accountability Matters More.

At Gunnison Sheet Metal & Roll Forming, we're not just producing roofing panels and trim packages.

We're building relationships with contractors who count on us.

Supporting local construction throughout Western Colorado.

And sharing the real stories behind the work through our Shop Talk series.

Because craftsmanship isn't just about the finished product.

It's about the people, processes, and pride that go into making it.

More Than Manufacturing Steel

Every fabrication shop has stories like this.

The difference isn't whether mistakes happen.

The difference is how you respond when they do.

At Gunnison Sheet Metal & Roll Forming, our philosophy is simple:

If something isn't right, we make it right.

That commitment extends beyond our manufacturing process. It's part of our partnership with contractors, builders, and homeowners throughout Western Colorado.

Standing Seam vs. Exposed Fastener Metal Roofing: Which Is Right for Your Project?

Wed, 09 Sep 2026 20:19:20 GMT

If you're considering a metal roof, one of the first decisions you'll make is choosing between standing seam and exposed fastener metal roofing. Both systems offer exceptional durability, but they're designed for different applications, budgets and longevity.

Whether you're building a custom mountain home, replacing an aging roof, or planning a new agricultural or commercial project, understanding the differences will help you make a confident decision.

At Gunnison Sheet Metal & Roll Forming, we manufacture both standing seam and exposed fastener steel panels right here in Gunnison, helping homeowners and contractors throughout Western Colorado find the best solution for every project.

What Is Standing Seam Roofing?

Standing seam roofing features hidden fasteners and raised vertical seams that lock adjacent panels together. Because the fasteners are hidden beneath the panels, the roofing system provides exceptional weather resistance while creating a clean, modern appearance.

Standing seam roofs are commonly selected for:

Custom homes
High-country retreats
Luxury homes
Commercial buildings
Residential Homes
Low-slope roofing applications

Benefits of Standing Seam Roofing

Concealed fastener design
Outstanding resistance to wind, snow, and moisture.
Minimal maintenance
Long lifespan (50-70 years)
Clean architectural appearance
Excellent long-term value
Custom panel lengths available

What Is Exposed Fastener Metal Roofing?

Exposed fastener roofing is one of the most common steel roofing profiles, featuring Corrugated, repeating wave-shaped ribs. And propanel, 36" wide panels seen across Colorado metal roofs.

While exposed fastener systems have long been used on barns and agricultural buildings, they have become increasingly popular for modern homes, cabins, restaurants, retail buildings, and architectural accents as an affordable metal roofing option.

However, there are value trade-offs as they require bi-annual maintenance where fasteners must be tended to. With Colorado's intense temperature swings, metal panels go through significant expansion & contraction everyday. This shift in temperature causes panels to move minutely, causing fasteners to loosen and "back-out." Therefore, bi-annual fastener maintenance is a must to prevent roof leaks.

Corrugated panels are commonly used for:

Residential roofing
Metal siding & skirting
Agricultural buildings
Shops and garages
Accent walls
Interior design features
Commercial buildings

Benefits of Corrugated Roofing

Cost-effective
Easy to install
Versatile for roofing and siding
Durable steel construction (20-50 year lifespan)
Available in many colors and finishes

Which Roofing System Performs Better in Colorado?

Colorado's climate presents unique challenges, including:

Heavy snowfall
High winds
Intense UV exposure
Freeze-thaw cycles
Large temperature swings

Standing seam roofing excels in these conditions because its concealed fastening system minimizes opportunities for moisture intrusion while allowing the panels to expand and contract naturally.

Exposed fastener roofing also performs exceptionally well throughout Colorado, when maintained, and remains a trusted solution for residential, agricultural, and commercial buildings.

The right choice often depends on your building type, budget, and design goals.
