You think you know everything about metal roofing?


The type of roofing that you choose will affect your home’s resale value, heating, and cooling costs, as well as the number of insurance premiums that you will pay. What are the advantages and disadvantages of metal roofing?



If metal roofing is properly installed, it should last as long as your house. It can survive high winds, easily shed snow, and seal out water. Metal is resistant to elements, insects, rot, fire, and mildew. Most companies will give warranties that range between 20 and 50 years for metal roofing. Paint finishes have a 30-year limited warranty, usually.


When compared with tile (750 pounds per square) and concrete tile (900 pounds per square), metal roofing is way lighter. Most varieties of metal roofing weigh between 50 to 150 pounds per square. Some types of metal roofing materials are applied over an existing roof. There will be no need for additional structural support or tear offs.


Most metal roofing materials come in 12 to 36 inch wide panels or multiple-shingle sections.  An experienced roofing contractor can install these quickly. Since the material is lightweight, you do not incur engineering and supporting structure costs.

Fire resistance

Metal roofs are noncombustible, giving them the highest rating, Class A. A roof’s classification is also determined by the materials beneath the surface which could ignite when there is intense heat. If metal roofing is applied over a combustible material, for instance, wood shingles, it will have a lower rating usually Class C.

Heat conduction

Metal will radiate the sun’s heat. This minimizes heat gain at midday. This cuts on the energy that you would have used for air conditioning. A dead-air space between the metal and roof deck increases energy efficiency.

Rain and snow

Metal is impervious to rain and snow. It is designed to interlock as the surfaces are hard and slippery.


Despite the many benefits, there are a few downsides to metal roofing. Manufacturers have striven to improve their products in a bid to solve many of these concerns, though.

Metal roofing costs

The initial cost of metal roofing is quite high. Since it is durable, you will ultimately save more when compared to other materials after living in the property for long.


A metal roof can be quite noisy, especially when it rains. You may need to install materials with structural barriers to minimize noise. You may also apply them over sound-deadening insulation and plywood sheathing.


If there is a severe hailstorm, large hailstones can dent your metal roof. The types of metal roofing that are more likely to dent are aluminum and copper, as they are softer than steel.


Some painted metal roof finishes can peel, fade, chalk, chip, and scratch. Walking on some types, especially those with a granulated-stone surface, will cause wear. During installation, care must be taken not to scratch or dent the roofing.
