Metal roof meet highest performance ratings available for fire protection, resistance to wind uplift, and hail damage. Metal roofing products are environmentally friendly—due to their recyclability, and solar reflectiveness which result in lower cooling requirements. Metal roofs do not mildew, split, crack, or curl. Metal is virtually maintenance free and can last 50 - 75 years or more. There are also a wide range of material choices—copper, galvanized or coated steel, stainless steel, aluminum and other coated metals—and several different panel construction options—standing seam, decorative stampings, 5V, and others. Metal roofing systems are durable and lightweight for both new and reroof applications.


Properly installed metal roofing is no noisier than any other type of roof. Metal roofing is typically installed over a solid substrate. Additionally, the attic and insulation provide a sound barrier. If you wish to install residential metal roofing over your existing roof, the metal roof will most likely be raised over the existing roof by means of furring strips. These furring strips will create an air pocket which will further deaden sound.

Metal Roofing Prices

Metal roofing costs about three times the cost of conventional asphalt roofs. The difference in metal roofing cost is attributed to a much higher price of metal roofing materials sold by metal roofing manufacturers, and a highly technically involved installation process that requires specialized skills, and specific training. The tedious and time-consuming installation process requires longer hours, precision and patience affecting cost of metal roof. On average, metal roof takes about two to three times longer to install than a conventional roof.

Metal roof can last a lifetime with little to no roof maintenance, while providing tremendous cooling cost savings, offering a distinct look to your home, and increasing its value.

Metal Shingles

Metal shingle roof is the basic type of residential metal roofing material. Metal roofing shingles usually feature a four way inter-locking design, which means that every single shingle is interlocked with six other shingles on all four sides. The advantage of the inter-locking metal roof shingles design is that it makes the whole system extremely reliable, because every shingle is being held in place by six other shingles.

Installing Metal Roofing

  • Tear off of the old roofing layer, in order to have clean metal roof installation. Although some metal roofs can be installed over shingles, we prefer to tear down all the layers before we install metal roof.
  • Once the base is naked, we install a breathable roof underlayment for extra protection.
  • Extra time is spent wrapping chimney metal roof flashing in special metal roof coating as it is very likely to leak.
  • First metal edging is installed, which is run all across the roof's perimeter.
  • Next, the first metal sheet is installed. The next sheet overlaps is.
  • The process of installing steel roofing is repeated all the way over the roof until the last sheet is left.
  • Extra amount of space is measured which goes over past the edge of the roof.
  • The process is repeated for the other side of the building.
  • Next the metal trim is installed, covering the roof's sides along the edges as well as the ridge peak of the roof.
