Metal Roofing FAQ

Do metal roofs attract heat and increase energy costs

Absolutely not. Compared to most other roofing materials, metal roofing is one of the most energy-efficient and coolest roofs on the market today. Large surface areas with thinner yet stronger material dissipated heat back into the atmosphere at a far superior rate.

Is metal roofing a better long-term value than shingles?

At Roofing World®, we provide a lifetime warranty on our metal roof projects in Alabama or Georgia. We also offer a lifetime warranty on our Poly Shingle™ projects. So it comes down to customer preference because our Lifetime Rib Panel Metal is approximately the same price as our Poly Shingle™.

Is metal roofing more prone to hail damage?

That depends on the location of the structure being covered and the gauge (thickness) of the material. For example, in Colorado, hail can be more than 2 inches in diameter, whereas in the southeast U.S. It’s doubtful you’ll have hail that exceeds an inch in diameter. This is a general weather pattern known by geographical location. 
If you’re in an area with the possibility of 2+ inch hail, 22 or 24 gauge roofing would be suggested, both of which are known to meet the criteria necessary for optimum hail protection. In most cases in the southeast U.S., you would be safe with 26 gauge panels. However, if you live near the southeastern coastal areas, 24 gauge would also help with high wind situations like a hurricane making landfall in your area.

Is all metal roofing created equal?

Like anything else in life, you have good, better, and best. The same applies to metal roofing. Let’s break it down. 
The thickness (gauge) of the metal plays a critical role in the quality of the roofing material, as does the quality of the metal alloys used. Paint or coloring is no different. Better alloys, increased thickness, and higher quality paint options will give you a far superior roof with protection that covers many potential issues down the road. These include: 
Increased Usable Lifespan. 
Less susceptible to damage from hail, wind, and falling objects, such as a fallen tree limb. 
Your budget 29 gauge metals are mostly for sheds and storage buildings. 29 gauge is the thinnest of all metal roofing panels. 29 gauge is more susceptible to oil canning (waviness and buckling of the metal) Make sure you keep trim, ridge, and flashing the same gauge when building with thicker material. The lessor metals used in these areas will leave you exposed to points of failure on the roof in extreme weather conditions. 
Never short cut to save a few dollars that could cause catastrophic failure in straight-line winds from thunderstorms and hurricanes. 
Make sure you use quality fasteners. Historically, fasteners are the first point of failure on metal roofing due to the 2nd law of thermodynamics, or entropy. Everything is in a state of degradation from the elements and time. Everything wears out. How long your roofing lasts is based on the decisions you make in your choice of materials used. 
There are far superior fasteners on the market that didn’t exist just 20 years ago. There are now lifetime fasteners that can most literally weather the storm. 
For example, we use a lifetime screw on our Rib Panel roofs because the screw is often one of the primary leak points for metal roofs. Our standing seam product line has hidden fasteners and a lifetime paint and is considered the top choice for the best-looking, longest-lasting metal roofing system in Huntsville, Alexander City, Bay Minette, Columbus and all around Alabama and Georgia.

How do I choose a metal roofing contractor?

Make sure they have all of their bells and whistles. Are they insured with liability and workers comp insurance? Are they licensed in the state they are operating, if applicable? Do they have a physical office? Do you see their vehicles moving about the area? There are tell-tale signs that separate the wheat from the chaff. Call references and have a chat with them. Check their Google reviews.

Are metal roofs energy-efficient?

Metal roofs are one of the most efficient roofing systems on the planet and work almost anywhere if you choose the material quality based on your location and needs. They are thin sheets of metal that dissipate heat quickly, shun and reject radiant cold, and help maintain stability against moisture penetration.

What are the pros and cons of metal roofing?

Let’s do the cons first because it’s the shorter answer. The cons are the cost. Metal roofing costs more than most other residential roofing systems. 
The pros? There are metal roofs still working that were applied over 100 years ago and remain functional and decent looking. Metal roofs are energy efficient while offering excellent performance during weather events. They are known for their longevity and durability. Metal roofs also maintain their aesthetic appeal for a very long time. Metal roofs can also help cool your home.

How does metal roofing hold up to hail?

The answer to this depends on the location and gauge of the material. As covered above, look at the gauge of the material you intend to use, then consider the options for your location. Only 22 and 24 gauge metal roofing panels and trim are approved to handle larger hail storms with less damage. 26 gauge is fine for most residential applications.

Can you install metal roofing over existing shingles?

You can install metal roofing over existing shingles, but it is not always recommended. It is possible if the shingle roof is in excellent condition and was installed correctly with the best materials, such as a high-grade synthetic underlayment. In this scenario, the metal is only being installed over the shingle because of style preference. In other cases where the asphalt shingle roof in Alabama  or Georgia is past its useful life and has experienced some level of leakage or failure, installing a metal roof over it is highly discouraged. In this scenario, one would be installing a new product on top of a bad foundation. The roof structure has already been damaged, and it could also be trapping moisture underneath the new metal roof.

Why do roof shingles have granules?

Shingles are composed of 3 essential parts—a fiberglass mat, asphalt that encases the fiberglass mat, and the granules. The sun deteriorates asphalt, so the granules protect the asphalt from solar deterioration. It’s also a cool way to build out some nice colors and aesthetics.

Do you need roofing felt under shingles?

Yes and no. Roofs are covered by insurance like anything else on or in your home, but with some exceptions. If it’s affected by wind damage, hail damage, or that tree limb that fell on your roof in a recent thunderstorm, insurance will likely cover it. If it’s natural wear and tear, your possibilities are slim to any of getting insurance to cover the cost of replacement. It’s safe to bet if your roof is older than 20 years, insurance coverage won’t be available in many policies.

Should I replace my roof before listing my home for sale?

Most experts in the real estate industry suggest that curb appeal accounts for a lot of decision-making when purchasing a new home. The roof is an essential factor in curb appeal. When a house comes under contract, it gives the prospective buyer a chance to negotiate a far lower price because of an aged or damaged roof. It’s almost always beneficial to replace a worn roof before placing it on the market. Studies show that you will receive most, if not all of your investment, in a new roof within three years of installation.

Will I have to replace gutters and downspouts at the same time?

That depends on the condition of the gutters and the surface it’s affixed to, such as facia boards. If they are rotted from poor roof maintenance, you’ll need to replace the facia and the gutters, as an example. 
You should have your gutters cleaned and inspected at least once a year, but preferably twice a year in the spring and fall.
