Residential Metal Roofing
How A Metal Roof Stands Out
Whether you have a building a new home or looking to replace an existing roof, metal roofing gives you an elegant and premium look to your home while being one of if not the most durable solution for your roof. Different metal roof materials have different advantages and disadvantages depending great on the environment and personal taste. Choices include aluminum, galvalume steel, galvanized steel, copper, rolled zinc, titanium, stainless steel and more. The versatility of metal allows it to be in nearly any shape and color you could imagine. You can go with a more common standing seam panel design or go for a Tile, Shingle, Shake or Slate design to emulate a classic look with the durability of a metal roof.
Galvanized Steel Roof
One of the ways a Steel roof can be made to resist rust is through galvanization. Galvanized steel is made by taking an iron and carbon steel and dipping it in a molten bath of zinc. The galvanic protection keeps the base from corroding. The amount of coating on the most common of galvanized steel is G-90. The number in G-90 refers to .9 ounces of zinc per sq.ft. of the surface. The thickness of the steel itself is measured in a gauge number, the lower gauge numbers are actually for thicker metal.
For roofing contractors, this is the most commonly used metal panels due to the combination of familiarity and cost. Nearly everyone who knows about metal roofs has heard of galvanized steel. The cost and durability in dry conditions make this a go-to for many homeowners. If your roof is going to be near the beach or other areas with salt in the air we would not recommend using a galvanized steel roof.
Galvalume Steel Roof
Aluminum has become more popular for metal roofing purposes in recent years thanks to a few advantages. For applications near saltwater and coastal areas, aluminum is ideal because it will never rust, unlike steel panels. The light weight of the material means for roofing it can be used on a wider range of homes without needing additional reinforcement or a structural engineer. Aluminum also can be formed and shaped for any application. Another great benefit of aluminum for roofing is a high percentage of recycled content. A piece of aluminum roofing will be made from between 90% & 95% recycled material, most of which comes from beverage cans.
The few downsides to aluminum may also be a concern in some cases. The cost of the aluminum is more than a similarly designed steel roof. Depending on the thickness chosen, aluminum is more likely to experience dings and dents, especially from larger hail.
A copper roof is often thought of as the top of the line of metal roofing.
Not only because of the distinct look but also the larger price associated with it. It is very rare to see a home with an entirely copper roof. It is more commonly used for dormers, near entryways or car garages and bay windows. Copper can be installed in a standing seam or shingle style. Copper is beloved for its blue-green patina that forms over years of exposure. Copper roofing is also known for its long life in part due to the patina coverage. It can take anywhere from 8-15 years of exposure to get a full coverage of patina over the clean copper color.
The pros of copper: a very distinct look, relatively easy to install, very durable. Some cons of using copper on your home’s roof, it is the most expensive metal option. Copper roofing will take years to achieve its final patina unless you use a pre-patinated or treat the copper to speed up the process. Also once the patina has developed, water runoff may leave stains or streaks other materials it comes in contact with.
