Installing an exposed fastener metal roof.

What is a 5V Crimp Roof Panel?

Also known simply as the “5V,” a 5V crimp is a simple panel that has inverted V-shaped rises. The rises overlap, and a fastener connects them to the roof deck. These roofs are commonly made with Galvalume®, a steel coated with zinc and aluminum.

What are Exposed Fastener Metal Roof Panels?

Exposed fastener metal roofing is a system where the panels are fastened to the roof. The panel edges overlap with a raised crimp so that the fastener, or screw, goes through both metal sheets and into a strut or roof deck. The name comes from the fact that the fastener is exposed, unlike standing seam panels which hide the fasteners. You can use exposed fastener roofs on a variety of buildings as a cheaper alternative to standing seam.

Exposed Fastener Metal Roof vs. Standing Seam Metal Roof  

Standing seam metal roofs are often considered durable, temperature resistant, and provide a sleek, modern appearance as the fasteners are hidden. However, they are more expensive, and installation is labor-intensive, driving the price up even higher over asphalt shingle roofs. In short, not everyone can afford them. This means there is an opportunity to find customers who prefer the lower-cost exposed fastener metal roofs.

Exposed fastener metal roofs offer some advantages. As mentioned, they’re generally less expensive. They’re easier to install, which further lessens the overall cost. Due to their durability, they stand up to storms and don’t require much maintenance. Another benefit is that they can be painted or purchased in a variety of colors. Also, the panels can be wider than the standing seam, so there’s less overlap. Because they’re customized, you can reinforce them as necessary.

Where Are Exposed Fastener Metal Roofs Used?

You can install exposed fastener metal roofs on about any structure, but keep in mind, they are not going to provide the kind of insulation and protection as a standing seam roof without an underlayment. Therefore, while they have become more popular on houses, they have long been common on agricultural outbuildings.

You’ll likely find a standing seam system in many U.S. homes with metal roofing. It looks good, holds up to the elements, and fits in with the styles of most houses. However, in southern states like Florida and Georgia, exposed 5V crimp roofing offers a classic old-time look, known as the Key West Style.

Metal roofs are popular in southern states because they are lightweight, durable, and reflect heat away from the house. 5V Crimp complies with the Florida Building Code structural requirements and has state approval with: Min. 26 ga., 24″ wide through fastened roof panel over min. 19/32” thick plywood deck with fasteners through panel rib (FL #11903.1).

As mentioned, exposed fastener metal roofs have long been used for agricultural structures. The exposed fastener is standard in rural areas on barns, garages, hen houses, and sheds. If your business is in a farming community, exposed fastener roofs will be typical, and a 5V machine may be just the thing. Also, they are used on commercial structures. The NTM 5VC-5V CRIMP can handle most commercial work.

Exposed Fastener Metal Roof Installation

Quality installation is everything when it comes to exposed metal roofs. Most often, the washers deteriorate even while the roof is still in good shape. For that reason, the installation plays a key role. If screws are angled, overdriven, or underdriven, the washer can’t do its job. The washer should act as a gasket between the screw and the roof to prevent leakage. Make sure to firmly fasten the screw against the strut or wood framing to keep the washer in place. Craftsmanship, therefore, is vital.

For homes, install 5V Crimp panels against a solid roof deck with a waterproof underlayment like Sheffield Metals’ SHARKSKIN® ULTRA and SHARKSKIN® ULTRA SA or Drexel Metals’ MetShield® Synthetic. Consult your metals supplier for advice on what underlayment is best for your material.
