Metal Roofs - The Safe Choice

by Ryan McCall

Roofing is a critically important consideration for any new home, and a significant replacement expense for existing homes. When selecting a roof, take into consideration initial cost, lifetime cost, durability, life span of the roof, appearance, and the length of time you intend to live in the home. When all factors are considered, metal roofs are an attractive choice for many homeowners.

Modern residential metal roofing has come a long way from the corrugated "tin shed" appearance once associated with metal roofs in both appearance and functionality. They now have a much more esthetically pleasing appearance and all the advantages of their high tech construction. Pluses include exceptional durability, fire resistance, good performance in high wind conditions, heat reflection, low weight, and relative ease in installation. Drawbacks are mainly cost, low insulation factor, noise during rain or hail, and the potential for both denting and chipping.

Metal roofs are very resistant to wind damage, such as from hurricanes, and so are an appealing option in areas vulnerable to wind damage. Metal types of roofing also receive the highest fire retardant rating. As such, homes with metal roofs may have a higher asset value, and enjoy lower insurance rates.

Metal roofs reflect heat from the sun, reducing the costs of cooling the house during the summer. On the flip side, metal roofs are not good insulators. However, proper installation of dead space beneath the roof, and between the underlying components, can make up for metal roofing's poor inherent insulation. Special sound deadening insulation can reduce loud noise from rain and hail. Another factor when considering a metal roof is that heat can cause expansion and contraction, sometimes detaching the structural restraints.

Metal roofs are lighter, require less support from underneath, and as such can reduce construction costs. The lighter weight also makes it possible to install a metal roof over the top of an existing roof, saving the time and expense of having to remove the original roof. Installation of metal roofing typically takes less time too, as the metal sheets cover a large area. On the other side of that coin, replacing a larger section, should it become necessary, may be more difficult. Metal roofing sections may also prove more difficult to match if a replacement is needed, or an addition is built.

The often greater initial expense of premium metal roofing can make the option less attractive. However, discount metal roofing is available. Metal roofs enjoy a 20 to 50 year life span, and may outlive the rest of the house. Therefore, the total cost of ownership can be much less in the long run, particularly for those people who are planning to stay in their home for a good portion of the metal roof's life span.

Residential metal roofing has become more popular because it is lightweight, fire resistant, wind resistant, very long lasting and now even attractive. While metal roofs are still more expensive than most other types, they are more affordable than ever and discount metal roofing is available as well. The higher initial cost may be offset by lower maintenance costs and less need for replacement over the life of a house. Construction costs may also be less since these need less support. Metal can reflect the sun to make summer cooling less expensive and are easily insulated for winter warmth.
