Frequently Asked Metal Roofing Questions
How expensive is metal roofing?
The cost of a metal roof will vary based on the size of your home’s roof. Over the life of your home metal roofing is easily the most economical roofing material. With a metal roof installation, you’re receiving the highest quality roof money can buy with an incredible return on your investment.
Do I need to remove my existing roofing material?
Typically, yes. If you have a traditional asphalt roof, then it’s recommended that your existing asphalt shingles be removed. There are two primary reasons for removal. The first concern is weight stress. Ideally, you don’t want outdated asphalt shingles adding unnecessary weight strain to your roof. Additionally, you don’t want your old roofing materials to interfere with the overall strength of your new metal roof. Asphalt shingles rely on adhesive to keep them down under high wind conditions. Therefore, installing a new roof over existing old, curled, or split shingles may result in a weakened system. Unlike asphalt, metal roofs are light weight and rely on a metal interlocking system instead of adhesive.
Are metal roofs noisy?
No. It’s a common misconception that metal roofs produce a lot of noise. On old barn roofs, the metal is visible from the interior of the structure causing contact with the roof from rain and other objects to carry sound throughout. With residential housing, metal roofing is often installed over a solid substrate that acts as a sound barrier. Furthermore, attic space and insulation serve as additional barriers for sound. All in all, research has shown that metal roofs aren’t any noisier than traditional roofing products.
Will my metal roof rust or fade with time?
The answer to this question depends on the type of metal used. Copper typically does not corrode which allows the metal to maintain its beauty and shine over time. Aluminum needs to be protected against its natural tendency for oxidation, which leads to white rust. Steel must also be protected against oxidation to avoid red rust. It’s crucial to make sure that you’re working with knowledgeable and experienced roofing contractors who understand how to take steps to prevent galvanic action. Galvalume coatings combined with zinc technology protect steel from rust. Furthermore, paint coatings such as Kynar 500 offer an extremely high performance finish that is guaranteed not to fade or chalk.

What will my metal roof look like?
Metal roofing products are available in a variety of different colors and styles. The traditional and most popular look of metal roofing is what’s known as standing seam. With the standing seam style long panels of metal are laid down from eave to ridge. Keep in mind this is no the end all be all roofing style.
Will my metal roof retain heat?
Yes, which is why metal is far more energy efficient than other roofing materials. Being a heat reflective material, metal reflects away sunlight in the summer which reduces the level of heat transmitted into your home. Likewise, heat from the inside of your home is reflected back in from the underside of the roof to retain heat in the winter.
Will the installation of a metal roof affect cellphone reception?
No. Chances are you’ve already used your cellphone inside of a metal roofed building. Consider the restaurants, shops, banks, and churches you regularly visit. Many of these buildings have metal roofs or metal decks beneath flat roofs. Installation of a metal roof will have no noticeable effect on your cellphone reception.
Can you install attic vents on a metal roof?
Yes. Attic ventilation is crucial for many Michigan homes. Attic ventilation rids attics of unhealthy levels of moisture which eventually lead to mold. Vents also reduce heat gain in the summer and ice dams in the winter. Attic ventilation can, and usually should, be installed on your metal roof.
