Drawbacks to a Metal Roof.

Though metal roofing offers many advantages, there are drawbacks.

Cost: The biggest drawback is initial cost.

Noise: In a rainstorm or hailstorm, living beneath thin sheets of metal is bound to be noisier than living beneath thick slate or tile. Noise can be controlled both by using materials that have structural barriers to minimize the drumming effect and by applying them over sound-deadening insulation and solid plywood sheathing.

Denting: Just as your car will dent if a golf ball hits it, a metal roof can dent if large hailstones fall on it. Aluminum and copper, much softer than steel, are more prone to denting. Some types are guaranteed not to dent, however.

Access: There may be occasions when a professional need to snake out a vent pipe or a chimney sweep needs access to the flue. Not all metal roofs can be walked on, it will be dependent on the product and type of construction.

Care: Some painted metal roof finishes can peel, chip, fade, scratch, or chalk, although nearly all are guaranteed for 30 years. Walking on some types, particularly those with a granulated-stone surface, may cause wear.

Leaking: A metal roof must be installed correctly.

Expansion & contraction: Metal expands and contracts as it warms and cools.

Modifications: Any remodel or add on to your home 10 or 20 years from now, it may be difficult to match the material.

House fire: Though metal roofs are good at guarding against a fire that approaches from outside a house (such as from flying sparks and embers), they are not ideal for fires that start inside a house. With a serious house fire, firemen may need to cut through the roof to put out the fire—this job can be much more difficult and take longer if the house is capped with a metal roof.

Benefits of Metal Roofing.

The Look: Metal roofs are available in more styles, profiles, colors and patterns than any other roof material.

Life Span: Nothing lasts forever, but the right choice of metal roofing can endure for many lifetimes.

Versatility: A light weight design and range of profiles, metal roofing offers owners more choices than any other material – particularly for a re-roofing project. There are very few materials that go over existing roofs as successfully as metal.

Nature: Metal roofs are light weight and rigid. Another big advantage of a properly configured metal roof is tremendous resistance to high winds. In fact, there is no better material for resisting the damage of extreme weather.

Because metal roofs are mechanically fastened and don’t rely on a rapidly aging adhesive like an asphalt roof (which is why wind warranties on asphalt roofs all expire after only five years!), they are the most durable material for all weather conditions.

Environmentally Friendly: Metal roofs are manufactured with a significant percentage of recycled material, closing the loop for efficient use of materials, and they offer assemblies that dramatically reduce the amount of heat accumulated in an attic, making them very energy efficient. While some finishes are Energy Star certified. (Research your company!).
