Dallas Metal Roofing FACTS by Dallas Metal Roofs

Sheet metal roofing questions and answers and facts.

How does the cost of a metal roof cost compare to other roofs?

Metal roofs are a premium product and cost somewhat more than a 20 year warranty asphalt/fiberglass shingle roof; however a metal roof can cost substantially less than many of the high-end architectural shingles now being sold. Additionally, metal roofs have many advantages and benefits over asphalt/fiberglass shingle roofs.

See our specials on Galvalume: Material costs are as low as a standard 30 years shingle. Why re-shingle every few years due to hail when you can just be done roofing your home or business forever.

How about resistance to wind damage?

All metal roofing products are very wind resistant. Many styles have been tested to withstand hurricane force winds; and wind warranties can be as high as 120mph.

Is a metal roof fire safe?

A steel roof is the most fire safe roof. It is classified as a noncombustible roofing material with a Class A rating — the highest rating given.

How does the weight of a metal roof compare to other types of roofing?

Much to many peoples surprise, metal roofs are significantly lighter than other types of roofs. Typically they weigh less than one-third the weight of asphalt/fiberglass shingles; and are as much as 75% lighter than clay, concrete or slate.

Will a metal roof rust?

Galvalume coated steel roofing panels are protected by layers of metallic and polymer coatings. Industry studies have repeatedly shown them to outperform the corrosion resistance of other coated metals. They are available with warranty’s as long as 50 years.

Steel panels not mixed will rust if not coated properly. Durning installation, colored panels are scratched and need to be touched up to avoid rusting

Using what is called Spanish Galvalume will also give you problems in the future. Make sure you use a reputable supplier that does not cut corners. We prefer using DFW Roofing Supplies and M.R for all our coil stock needs. We fabricate all our panels on site to length

Does the color fade?

Metal roofs are painted with high-performance polymers that have exceptional weathering properties. Over time you might notice a slight change in color due to the settling of airborne contamination, but occasional rain or washing the roof with a garden hose (from the ground) will keep the roof looking like new.

These colored finishes will fade in time and turn a chaulk white. Kynar paints are expensive and using a steel panel versus galvalume will require repainting with in 20 years or earlier.

What about lightning?

Steel roofing is no more susceptible to lightning than any other roofing material. Lightning most frequently strikes the highest point in any terrain; and if your roof is at the highest point of the surrounding terrain, you can install lightning rods.

If I’m reroofing, do I have to remove the old roof before installing the metal roof?

Usually not if you’re installing the metal roof over existing asphalt, fiberglass or composition shingles (maximum of two layers thick). In most situations, the metal roof can be installed directly over the old roof.

Will a metal roof make my house hot?

Actually, a metal roof can save you money on your a/c costs because it has a higher heat reflectivity than other roofing products like asphalt/fiberglass shingles, wood, tile, etc. During the summer it makes buildings cooler by efficiently reflecting away sunlight and reducing the amount of heat transmitted into the building. Likewise, it makes buildings warmer in the winter by reflecting inside heat from the underside of the roof back into the building. This good thermal reflectivity translates into energy savings by reducing cooling costs in the summer and heating costs in the winter.
