Compared to traditional roofing materials, maintenance is virtually eliminated with a TapcoMetal roof. Unlike traditional asphalt composition shingles, wooden roofing shingles or cement and clay roofing, TapcoMetal roofing will not absorb moisture and grow unsightly algae, mould and fungus, which means your roof keeps looking beautiful, and significantly reduces its maintenance costs. TapcoMetal is made from highly corrosion-resistant AZ-50 Galvalume® steel specially prepared & treated with proprietary primer to enhance TapcoMetal’s acrylic adhesion. Its base coat is a proprietary special formulation developed by the world’s largest resin supplier to promote long-life performance in all climates. Finally, TapcoMetal is coated in finely graded, non-oiled, natural granite granules that enhance adhesion and provide the tightest granite stone coat matrix on the market today. TapcoMetal SHAKE is a batten-only profile and is fitted to felt and batten roof installations from 12° to 90°.

Q. How long has Stone-Coated Steel roofing been around?

A. Stone-coated steel roofs occurred during World War II when tar & sand were used to cover galvanized steel bunkers. After the war, the practice was commercialised and the first roofs were produced. Stone coated steel roofs have been protecting buildings for over 55-years, but the product technology today bears little resemblance to early practices due to advances in the chemistry of coatings and acrylics.

Q. Will a Steel roof make my home hot?

A. No. A properly vented steel roof moves air both between the shingles and the underlying deck as well as moving air from vents under the decking. Heated air is allowed to dissipate through the ridgeline as cooler is drawn through eave vents. Reduced energy bills can result from airflow both under and over the decking.

Q. Can you walk on a steel roof?

A. Yes. Some care must be exercised while walking on the roof, but note that roofers walk all over the shingles during the installation process.

Q. Is a steel roof noisy in the rain?

A. The combination of dead-air space and the stone coating minimise outside sounds. One rural couple standing directly under a stone coated steel roof observed that they could hear the rain striking a metal building about 50-feet away, but couldn’t hear any noise from the stone coated steel roof directly overhead.

Q. How wind resistant is a steel roof?

A. TapcoMetal roofing panels have been proven to resist wind speeds in excess of 120-mph. One homeowner’s roof survived tornado force winds completely intact. “We lost 12 large trees… the shingled roof of our garage…a 14′ x 14′ (2″ x 6″) pump house deck slammed into the house and buckled the brick. You said it would hold up in a tornado. I’m writing to tell you it will.” Bill Jamieson.

Q. How do the granules stay bonded to the steel?

A. Specially graded ‘Non-Oiled’ natural granite stone chips, produced by SGI Corporation are used for all TapcoMetal stone-coated products. The granules are embedded in a UV resistant acrylic polymer for a lasting bond to the steel substrate.

Q. Will a steel roof rust?

A. The steel substrate is protected from corrosion by layers of metallic and polymer coatings. TapcoMetal has an advanced metal composite developed by BIEC International and introduced in 1973 as aluminium-zinc coated steel. The composite improved earlier metallic coatings by applying an aluminium-zinc alloy to the steel in a continuous hot dip process. The aluminium creates a barrier coat while enhancing the long-term performance of zinc and its ability to protect breaks in the coating. Galvalume® coated steel has repeatedly been shown in industry studies, conducted over the last 30-years, to outperform the corrosion resistance of other coated metals. This is why the TapcoMetal roofing panel is referred to as “The final Roof”, and is backed up with a 40-year warranty.

Q. Does the color fade?

A. Though sized more precisely, TapcoMetal uses the same stone granules used by asphalt shingle manufacturers for over 50-years, so history demonstrates that fading is not a problem. Over time, a slight change in color may occur due to settling of airborne contaminants; however periodic rain or washing the roof with a garden hose will keep the roof looking new.

Q. Is a steel roof fire safe?

A. Steel roofing is classified as a noncombustible roofing material (Class A). TapcoMetal panels when installed over combustible materials like wood shakes or shingles, the resulting roof assembly can be classified as A, B or C depending upon the type of underlay installed between the old roof and new roof. The lightweight (1.5-lbs/Sq-ft) strength of the steel roof helps prevent roof collapse onto occupants exposed to fire within their residence.
There are many examples of the safe fire performance of stone-coated steel roofs in areas subjected to fire storms. Additionally, the lightweight strength of the steel roofing precludes it from crashing down on occupants exposed to fire within their residence.

Q. How long does it take to install a steel roof?

A. Usually only a few days. The complexity of the building’s roof is the primary factor in determining the time required. Complex roofs require more time than basic designs.

Q. What is the installed weight of a steel roof in comparison to other products?

Steel Roofing6.10kg
Standard (3-Tab) Asphalt Shingles**9.28kg to 10.50kg
Wood Shake/Shingle*12.21kg to 14.65kg*
Heavyweight Laminated Asphalt Shingles**14.16kg to 21kg**
Clay / Concrete Tiles*43.94kg - 58.59kg*

*Cedar, Clay & Concrete product weights are all DRY weights, all 3-product weights increase when WET.
**Asphalt Shingle weights DO NOT include the weight of new plywood. OSB sheathing.

Q. What does hail do to steel roofs?

A. TapcoMetal panels have earned a UL Class-4 Impact Resistance rating from Underwriters Laboratories. Except under the most extreme storms, TapcoMetal panels show no visible effects from impacting hail stones. Some insurance carriers extend a discount on premiums to homeowners that have a UL Class-4 TapcoMetal roof.

Q. Are steel roofs more susceptible to lightning strikes?

A. Steel roofing is no more susceptible to lightning than other roofing materials. It has been demonstrated that lightning strikes most frequently the highest points of terrain. Where concerns exist, lightning rods can be installed on roofs that are the highest point of surrounding terrain.

Q. How does Tapco market its product?

A. Tapco has an open policy, we sell to homeowners, contractors and distributors.

When you contact us, our representative will guide you as to how many TapcoMetal panels you will need to cover your roofing project. However, the general idea is to measure how many square metres your roof covers then use the following quick-step method:

TapcoMetal Quick-step Material Calculation Method
  1. Determine the roof square metres without waste.
  2. Add linear metres of hips & valleys and multiply this by 0.81.
  3. Add together the totals from steps 1 and 2 above.
  4. Multiply this total by 1.06, which gives you the roof square metres including waste.
  5. Multiply the total from step 4 above by the number of TapcoMetal panels needed per square metre using the table below.
SHAKE 2.16

Note: Advice from our technical department should also be sought when installing on high buildings and/or in exceptionally windy areas.


A square metre is a metric measurement of area. If the area involved in your roofing project is square or a rectangular, measure the length and width of the area, using a metric tape measure or a meter stick. Multiply the length, in metres, times the width, in metres. That will give you the area of the square or rectangle in square metres.

If the area involved is not square or rectangular, sketch the area to scale on a piece of graph paper. You can make sure that it is to scale by allowing each division on the grid to equal a certain number of metres. Break up the sketch into rectangles, squares, triangles, and even circles, if necessary. Apply the appropriate metre-based formulas to each shape on the graph to determine the area of each shape in square metres. Multiply length times width for squares and rectangles. Multiply base times height and divide by two for triangles. Measure from the centre of a circle to its outer edge to find the radius; then multiply the radius times itself and multiply that figure by 3.14, which is “pi.” Add the areas of each shape to find the square metres of the entire area.

Please Note: The details on this page are for guidance only, and the Tapco Group will not be held responsible for any incorrect measurements undertaken by you or your architect or roofing contractor. It is your sole responsibility to ensure that any measurements and quantities ordered are correct.
