Cost & Benefits of Ribbed Metal Roofing: Pros & Cons

Ribbed metal roofing is in the same family as Corrugated metal roofing. It is made in a similar fashion (at a metal mill), attached to the roof in the same way, and installation costs are about the same.

The key difference is in the appearance. Ribbed metal can be mistaken for Standing Seam, which is on the upper echelon of metal roofing.

Cost

Based on the price of materials alone, Ribbed metal paneling is certainly in the same ball park as Corrugated metal paneling.

The pricing does depend a bit on who you are purchasing the materials from, but a price range of $1.00 to $3.00 per linear foot is what you’ll routinely find. — This assumes you are going with a coated steel (i.e. galvanized or Galvalume), stainless steel or aluminum product. Then add a minimum of $2.50 to $4.00 per sq. ft. for professional installation, and you’ll get a base rate of $4.00 to $7.00 per sq. ft. of ribbed metal paneling installed.

Note: Labor costs may be higher than $3 per sq. ft. Total cost ought to be below $7.00 to $9 per sq. ft. installed, which means the cost of warrantied labor could go as high as $4.00 to $6.00 per sq. ft., in some cases.

Why would installation costs ever be that much higher higher? Well location is part of it, along with complexity of your roof, slope, or pitch, of the roof, and amount of custom metal flashing required for the job.

If your existing roof is to be torn off and disposed of, that would be a separate line item cost. Same goes with possible repairs to the roof. The good news is that Ribbed metal roofing can be installed over the existing roof.

For an average sized roof (say 1,600 sq.ft.), the total installation cost is likely to fall within $5,500 to $9,000.

A very large roof, say 3,000 sq. ft. would then be double, right? Not necessarily. If it is a non-complex roof, it could be significantly less than double as the more product you order and the more work being provided to the contractor, the less of an overall charge per sq. ft. the project could result in.

ROI: With all metal roofing, the return (value to cost) on your investment will be excellent. It starts at around 86% and, again, depending on your location may be higher.

This means that if you were to spend say $10,000 for a ribbed metal roof and sell your home while the roof is still in great condition, you can plan to recoup $8,600 of that value just from this part of your home.

Residential homes along the east coast of the U.S. tend to fetch better than 86% ROI.

Zinc: The Dark Horse of Metal Roofing – Zinc Roof Costs 2018-2019

There are not many roofing materials that can match the longevity, durability, malleability, flexibility, resiliency, and cost-effectiveness of Zinc.

Not even aluminum or copper! Zinc roofs are known to last for hundreds of years, even in the most extreme environments.

Truly unmatched durability, longevity, and classic beauty — that’s what zinc roofing offers to a homeowner. — At $12 to $15 per sq. ft. installed, it is the kind of value that is simply unmatched in all other roofing materials.

Zinc — Most Amazing Building Envelope Material You Never Heard of!

In the US, the whole idea of using Zinc as a roofing or cladding material for a house may sound other-worldly.

Aluminum and steel dominate residential metal roofing market, while asphalt shingles are by far the most popular overall roofing material.

When you also factor in natural slate, clay tiles and cedar/wood roofing options, Zinc barely registers on most people’s radars. Though this trend is changing, slowly.

Did you know? 70% of residential roofs in Europe are covered with Zinc. In Paris, this number goes up to 85%.

Metal roofing is often chosen for its durability and longevity. All properly designed and correctly installed high-end metal roofs are likely to last at least 50 years.

Yet, in order for that to hold true for Steel, for example, it must be coated with metallic finishes such as G-90 galvanized steel and Galvalume (zinc and aluminum coating), along with high quality paint finishes such as Kynar 500. With Zinc, as well as copper, that is not the case.

Both Zinc and Copper form protective patina, meaning they will not rust nor be adversely impacted by weathering.

Both of these metals benefit from aging, and their patina process.

With Zinc, it starts out dark, as in dark gray / near black and then changes to a patina light gray or bluish color. Zinc can also be painted virtually any color, which serves as a sacrificial layer prior to the patination process.

Did you know? Thanks to Zinc’s naturally-forming self-healing properties, it can provide years of virtually maintenance-free roof and building envelope protection

What makes Zinc truly fascinating is its resiliency. All metal roofs, including Zinc, can be scratched. With Steel, scratches in its coating layer will expose the base material to the effects of oxidation and corrosion.

With Zinc, it actually self-heals. You read that right, Zinc if scratched will self correct.

The protective (patina) layer of Zinc is technically hydroxyl carbonate that will, over time, reform itself and thus eliminate blemishes or scratches. This is one, of a few reasons, why the market for Zinc will often sell pre-patinated Zinc roofing.

As you may have guessed, Zinc is extremely durable. When steel is “galvanized”, it is really just adding a protective layer of Zinc to dteel base to protect it from oxidation, as Steel is naturally corrosive, or will rust when exposed to salt, water, or moist environment over a long period of time. galvanized and Galvalume Steel will forgo that aging for a couple of decades.

Like most metals, Zinc is insect-proof, fire resistant, and mildew / fungus-proof. Zinc also benefits from being non-toxic. Because of its low to non-existence toxicity level, soft zinc is marketed as replacement for flashing material for all roofs.

Back in the day, the traditional material was lead, then steel, but soft zinc, offers virtually the same level of durability with no known toxicity impact.

Did you know? Run-off water from Zinc is considered ‘clear’ or contaminant free, which most metals can’t readily claim. Thus, a zinc roof is a great option for homeowners interested in rain water collection.

Like many other metals, zinc is fully recyclable. Plus, it will reflect solar radiant heat, as most metals do to some degree, which prevents the unwanted transfer of heat from the roofing material into the attic space.

On the contrary: Asphalt shingles gain a lot of heat during the day and transfer much of it inside your home.

Moreover Zinc has even greater environmental value in that it takes less fuel to manufacture it, really to boil it and shape it into finished roofing product.

Did you know? Aluminum and steel use a good two to four times the amount of energy in their production compared to Zinc.

All this value would make you think it’s gotta be at least as expensive as Copper. Nope. Not necessarily.

Metal Shingle Roofing Costs and Value

Installing a metal shingle roof on a residential home will cost, on average, between $8.00 and $10.00 per sq. ft. There are a number of factors that determine that cost, and we’ll explore them in this guide.

It’s perhaps most important to realize that of the three primary options for metal roofing (the others being Standing Seam at the high-end, and Corrugated and Ribbed Metal Panels at the low-end), Metal Shingle is in the middle of pack in terms of costs.

Understanding Your Options

At first mention, metal shingles sound bland, or perhaps too risky of an option in an area where they would clearly be outside the norm (i.e. all your neighbors have asphalt shingle roofs).

Yet, when researching metal shingles styles and options for residential homes, you might be surprised to pull up some images that look a lot like asphalt shingles. 😉

Why would that be? Because the reality of metal shingles today, is that these are really metal tiles that are intended to mimic just about all other possible roofing styles designed for sloped roofs.

Slate tiles, ceramic tiles, asphalt shingles, cedar shakes and say redwood shingle are all materials that metal shingles can mimic.

From the curbside view, it would be hard to tell the difference between the metal material and its usual counterparts. That’s how diverse the metal roofing industry has gotten.

Add to this the idea that metal itself can have a pleasing appearance, as is the case with copper, zinc and painted aluminum and steel tiles. Gone are the days when metal shingles only have a silver/gray, metallic appearance.

Key Fact: There are really two basic types of metal shingles, or tiles: metal coated with metallic finish, often second coated with factory finished paint, and the second type which is often referred to as stone-coated metal tiles.

It’s the stone-coated variation that opens the door to having metal shingles that look nearly identical to asphalt shingles, because like asphalt shingles, they are coated with granules.

So, it’s not just color, but texture that allows metal shingles to obtain a great diversity in product options.

With texture as an additional option, slate, wood and ceramic are all possible appearances for metal roofing.

Then there is shape, which varies a bit by manufacturer, but for the most part are rectangular, or diamond shaped.

How it’s installed: Metal shingle installation relies on an interlocking system that makes for quicker installation and ability to hide fasteners.

Some manufacturers still go the route of having panels of say 4 tiles (per panel) that are adhered to the roof deck.

Panels are usually 4 feet long and are often installed over existing roofing (i.e. metal shingles can be installed on top of asphalt shingles).

Did you know? Interlocking tiles are now the 2nd most popular type of metal roofing for residential homes after standing seam.

The other consideration for shingle options is the material, or type of metal itself, but we’ll cover that in the next section.
