Metal Roofing Calculator
Metal Roofing Price Calculator helps estimate cost of metal roofs.
This is a specialty version of our free roofing calculator tool, designed to estimate metal roofing cost of following metal roof materials:
- Standing Seam Metal Roofing
- Aluminum Interlocking Shingles
- Steel Interlocking Shingles
- Stone Coated Steel (Decra, Gerards, All-Met, etc.)
- Exposed Faster Metal Roofing Systems: Corrugated Steel roofing panels / Vertical Rib panels / V5 Crimp panels
- Copper Roofing
- Zinc Roofing
Metal Roofing market, just like asphalt shingles roofing market differs from one geographic location to another – but there is one universal factor that keeps prices of metal roofs more in-line, from region to region. It is the cost of metal roofing materials, which is considerably higher than asphalt shingles, and is similar across the board. Another major factors that keeps metal roofing prices high, is the need for professionally trained installers, who know how to perform special trim and flashing techniques, which a regular roofer will not be able to do.

Additional information about Cool Roof energy savings and Metal Roof Life Expectancy.
* Cool Roof energy savings: Estimated energy savings are calculated against asphalt shingles roof, which is assumed as ZERO energy saved during the cooling period of the day.
Although any metal roof will be much “cooler” than asphalt shingles roof, average energy savings will depend on the color of your metal roof and weather it is a COOL ROOF – has reflective pigments in the coating. Most metal roofs coated with Kynar 500 paint, will be considered COOL Roofs. Still, the lighter is the color of your roof, the more solar heat it will reflect.
Keep in mind that even after the sun goes down, the heat stored in the shingles will still transfer inside your house, during the night. Metal roofs store almost no heat, and due to practical lack of contact between a metal roof and a roof deck under it (except points of attachment), most of the thermal heat stored in the metal roof will go into atmosphere, once the sun goes down.
** Life Expectancy of Steel Standing Seam roofs: Standing seam metal roofing is commonly made from two different metal – aluminum and steel. Aluminum standing seam roof will last 50+ years, while steel would last 40+ years.
Steel may last less if A) Roof panels were scratched during installation, and metal begins to rust, or B) Metal roof is of a low quality (e.g. cheaper acrylic paint instead of Kynar 500) or low quality metal galvanization may reduce the life of a steel metal roof. Therefore we estimate a steel roof to last about 40+ years. Keep in mind that chances the your steel roof will last well past 40 years mark, are very high.
Also, these numbers reflect the roof itself, and not the paint, which may begin to fade in 20 years, which is a standard fade warranty for Kynar 500 paint.
*** Vertical Rib steel panels: On average, most metal roofs will last more than 50 years when installed correctly. Only Corrugated Steel Roofing Panels / Vertical Steel Panels / V5 Crimp panels and similar metal roof systems installed with Exposed Fasteners (EF), will usually not last more than 20 years. Exposed Fastener Metal Roofs will also need re-fastening in about 10 years after installation and neoprene rubber gaskets will dry out and begin to leak. Also, most of EF metal roofs are made with cheaper 29 Ga. galvanized steel and painted with acrylic coatings instead of Kynar 500, which also shortens the life of such metal roofs.
Metal Roofing styles, used in this calculator:
Standing Seam Metal Roofing – Architectural style vertical panel metal roof system, which is installed with concealed fasteners, and panels are held down by special clips, hidden between the ribs of metal panels. These roofs are generally used on residential homes and businesses such as restaurants and shopping malls to create curb appeal, combined with long roof life.
Why are metal roofs more expensive than asphalt shingles?
Interlocking Shingles (Steel and Aluminum) Interlocking metal shingle roof, is arguably the most versatile metal roofing system that exists on the market. Interlocking shingles can be installed on nearly any roof, no matter the difficulty and and how cut up the roof is. Even a round tower can be roofed with metal shingles, while it will pose serious problems for other types of metal roofing, such as standing seam or stone coated steel.
Interlocking metal shingles have a reverse lock on each side, and each shingle is locked into the one below it and the one on its side. Shingles are then attached to the roof deck with clips and nails. In the end, each shingle is also held in place by another 6 shingles around it, making such metal roofing system very durable, and wind resistant. Revers locks also prevent the wind-driven water from penetrating the roof.
Installation of TAMKO Steel Shingles:
Metal shingles roof is also best suited for such roof flashing details as multiple skylights and chimneys. Because of low profile of metal shingles, the curb flashing will not stick up off the roof deck and the back pan of the curb flashing (place where 99% of skylight and chimney leaks occur), will be made of one piece and when done right, will never leak.

I would like to know how the costs were determined. And, in my opinion, stone coated steel lasts longer than the 35 years you have listed – but of course, this depends on the manufacturer. Since you list the name of my product next to stone coated steel, i would like to know more.

Hi Meredith,
Costs were determined based on material costs, and the installation difficulty and are based on my personal experience of working with this type of metal roof. I know that installation prices will vary greatly from one region to another, so I tried top average it out.
As far as longevity of the roof – they may last more than 35 years, but the exposed fasteners nailed or screwed right through the panel is the main reason that I chose that number. This is my subjective opinion, and does not reflect ONLY Decra products – the stone-coated steel roofs in general. If you want, I will remove “Decra” form the site, but this is what I think of the product. Of course there are cases of asphalt shingles roofs lasting in excess of 35 years, but also there are many cases of shingles failing in 5-10 years. Same thing with various metal roofs, and there are many factors affecting the system longevity.
Believe me – I’m not trying to take away from metal roofs in general or stone-coated steel in particular – I think metal roofs are the best for sloped roof application, but some systems are better than others. This is once again my subjective opinion based on experience of installing virtually every metal roof there is – here is my view about differen metal roofing materials: http://www.newenglandmetalroof.com/blog/metal-roofing-systems.php

should a mechanically fastened standing seam roof (for truly low-slope applications) be considerably higher than a so-called click-lock seam? from what i can tell many manufacturers will rent the tool! it doesn’t appear to be that much more complex (to my untrained eye). i can easily see the benefits of a double locked seam over a click lock. as a side note, in my area very few roofers appear educated on the mechanically fastened seam. yet, when i check out various manufacturers its about the only seam that they will spec or warranty for low slope (2/12 in my case). so whats the problem?

Hi Dave,
The manufacturers are doing the right thing by not warrantying the Snap-Lock standing seam metal roof on low slope application such as yours (2 in 12 roof pitch). The problem with snap-lock standing seam on low sloped roofs is that if water freezes at the bottom and melts in the center of the roof, it will flood the pans between the ribs and will penetrate the roof through the locks.
There are two solutions – obvious one is of course the mechanical lock, which can go on as low an pitch as 1 in 12. The other solution is sealed snap lock, where a special course of sealant / adhesive is added inside the snap locks and seals upon contact with the lower lock. This may be an issue if the lower lock is not touching the sealant. Also very few metal roofing manufacturers provide this type of snap-lock panels. I only know of FireStone BP selling it.
You should still go for a mechanical lock instead, as double crimped locks will now let any water penetrate the roof. I would advise you however not to install exposed fasteners system on low slope roof. Though it’s commonly done, these roofs leak often and much sooner than you would expect them to.
Good Luck
