The Nucor CFR Roof System is a functional roof specifically designed for low slopes.

Kemp Construction is a perennial award-winning installer of Nucor Building systems, in part because of the optimized flexibility of this metal building product.

The Nucor CFR Roof System has been extensively tested to ensure the highest level of performance for weather tightness, as well as, structural integrity.

The panels have been tested and approved by Factory Mutual and Underwriters Laboratories for wind uplift as well as hail and fire resistance.

Here’s Roofing Contractor’s Magazine explanations of what Factory Mutual (FM) Approvals mean, in layman terms.

As great as all this information is, I still have not given the answer I poses in the title of this blog post:

9 Reasons Nucor CFR Roof System Is The Best.

Well here goes:

Reason #1: The Raised Seam

See, the Nucor CFR System is a raised seam metal roof.

What this means is that the roof is designed to “float” to accomodate thermal expansion and contraction.

This is accomplished with concealed sliding clips which allow for up to 3″ of expansion and contraction.


Reason #2: Hand-Operated Crimping Tool.

The panel sidelap of the Nucor CFR System has factory applied mastic and can be completely erected without the use of electric seaming machines.

Just like an electrician needs crimping tools for joining wires,  a metal building contractor typically needs electric seaming machines.

However, Nucor Building Systems offers a hand-operated crimpingtool for seaming, as well as, seaming machine to achieve the Nucor Vise Lock installation option.

In other words, as a builder, Kemp Construction gets to chose which application is most appropriate.

Nucor Roll Lock™, Nucor Vice Lock™, and Nucor Vise Lock 360™ have all been tested to ensure maximum results.

Take a look at the Nucor CFR System Performance Datasheet found here.

Reason #3: Non-Handed System

Nucor CFR System is designed to allow the installer [hopefully you select Kemp Construction], to erect the metal roofing system in either direction.

This provides flexibility to choose the most efficient starting points on the roof.

This save you both time and money.

Additionally, in most cases the roof is installer has the option to either install either the roof or the wall system first.

Reason #4: Flexible Seaming Options

I lightly mentioned this earlier.

The roof can be completely installed without the use of electric seaming machines. An electric machine is available for use after roof installation when required due to high uplift conditions or specified criteria.

However, the seamer does not have to be run as the panels are installed.

In all cases the roof is installed and hand crimped leaving the electric seaming to be accomplished safely and efficiently as one of the last steps of construction.

Reason # 5 : Wide Range of Insulation Options

According to the Nucor Building System website,

Nucor CFR Insulation Options

The Nucor CFR Roof System is designed to work with a variety of insulation types including fiberglass batts, basic rigid board, and liner decking rigid board.

This offers the builder and owner flexibility when choosing the best system to meet the functional needs of the building.

It is recommended that some type of insulation be used with all CFR metal roof systems to prevent wind flutter or damage due to the effects of condensation.

Reason #6: Fasteners Outside The Building

At the eave and rigid locations, fasteners are uniquely placed outside the building envelop, greatly reducing the chance for water penetration into the roof system.

Reason #7: Patented Panel Splice Detail

Panel splices have been designed with a patented system to occur away from the purlin or joist so that normal tolerance found in construction will not hinder installation of the Nucor CFR System.

The continuous end-lap design provides continuity, as well as, reduced handling of panels during installation.

Reason #8: Factor Dimpled and Notched

Nucor CFR Roof System panels are factory dimpled and notched to aid the installer in providing your metal building project with a weather tight fit.

Dimples indicate fastener placement at the end lap and aid against fastener “walking”.

Reason #9: Solid Seam Design

The metal roofing system seam profile is intentionally “stout” to provide flexibility in the field, as well as, a positive lock by the electric seamer, when the seamer is required.

This all but eliminates the possibility of the seamer malfunctioning and damaging the seam as can occur with older “Pittsburgh-style” seams.


Hopefully, I have helped you see why I believe Nucor CFR Roof System is the best.

That said, there are four other Nucor Metal Building System options.
