Metal Roofs – What Are the Drawbacks?

[ad_1]

Metal roofing has been shown to present the homeowner with quite a few benefits. With benefits, often drawbacks are overlooked or left out altogether. Most drawbacks to owning a metal roof have been negated by improvements in manufacturing and design.

On the surface the most talked about drawback seems to be the price. The initial cost will run $150.00 per square for the cheapest variety and up to $600.00 per square for the best. The thing about this investment that makes it worth considering is the fact that most of these roofs last for the life of the house, without having to be replaced. This is a savings if you plan on remaining in the home for a long time. If you are only going to be staying in the house for a few years it wouldn’t be worth it.

Though some people claim to love the pitter-patter of the rain pelting the roof, the noise can reach thunderous crescendos depending on the torrent of the rain itself. This eventuality can be dealt with easily enough by using soundproofing insulation during installation. The materials and structural beams and other barriers will dampen the noise level efficiently.

Denting is another drawbacks. If you live in an area prone to having hailstorms, a metal roof may not be a good choice for you. If the metal that the roof is made from is either copper or aluminum, the denting will be a lot more noticeable since these are softer metals. You can find some that are of stronger metal that is guaranteed against denting.

If the roof is painted it may peel, chip and even fade in the hot sun. Metal roofs can be scratched during installation. But the good news is that the metal shingle roofing systems are installed from the top down which eliminates them from having to be stepped on at all. The upkeep is generally just a simple hosing once or twice a year.

Another drawback is that metal roofing materials that are installed as large panels tend to expand and contract. If the roof is not installed with fasteners that allow for the materials to breathe you could end up with loose panels or shingles. They are also harder to modify than other types of roofing materials, especially the larger panels. Then there is the fact that in ten to twenty years you may not be able to find an exact match to the metal you have. If you have an addition to the house the metals may be of a different hue.

Finally there is the lightening factor. Although it is a misconception that metal roofs attract lightening, it has been shown that trees and other high objects in the vicinity of a metal roof will probably get hit. All is not lost; you can easily rectify this problem by having your roof grounded.

Metal roofs are a bit more expensive but overall they are a good buy for their longevity and good looks. Besides they can be recycled whereas most shingles cannot.
