Your Burning Questions About Metal Roofing, Answered.
Will a metal roof make my home hotter during summer?
No. In fact, many metal roof owners have reported energy savings of up to 35%. Properly vented metal roofs allow airflow between the steel panel and underlying deck. Heated air dissipates through the ridgeline, while cooler air is drawn through eave vents. Metal roofing also comes with a special reflective surface, so sunlight bounces off of it.
Are metal roofs loud when it rains?
Some homeowners think that a metal roof is noisier than asphalt during a rainstorm. This isn’t necessarily the case.
While it’s true that metal can resonate sound more, today’s metal roofs are installed over solid wood decking to dull noise. Embossed textures of new metal roofs also help to disperse rain, reducing noise even further.
In industry studies, the decibel level for rainfall on an asphalt roof is 46, while the decibel level for metal roofs with underlying decking is 52. To put that in perspective, most people cannot distinguish sound levels that are five to eight decibels apart. In other words—the human ear can’t detect the different sound levels between a metal roof and an asphalt roof.
Does a metal roof qualify me for homeowner insurance discounts?
Yes. You can lower your homeowner insurance costs by up to 35% when you install a metal roof in Savannah, Hilton Head Island, and Beaufort. Contact your insurance provider for details.
How does metal roofing stand up to strong winds?
MUCH better than asphalt shingles. Asphalt shingles can blow off in winds of 70mph. In contrast, some metal roofing styles can withstand winds up to 200mph!
Does my current roof have to be removed before installing the metal roof?
It depends, but not typically. Metal roofing can be installed over existing wood shingle, shake, or composition roofs. It comes down to your specific situation, what you want to accomplish, and local building codes. We can help you explore your options!
Does a metal roof expand and contract with the heat and cold?
Yes—and you want it to. Metal naturally expands and contracts with changes in temperature. A quality metal roofer will install the roof to allow “breathing room” for proper expansion and contraction. Expansion and contraction are NOT a problem and will NOT negatively affect the life or performance of your metal roof. Period. Not allowing for expansion and contraction is where you can run into problems.
Will hail damage a metal roof?
Unless it’s freakishly large mutant hail, then no. The average hailstone is about one inch in diameter. Our metal roofs come with an industry-leading UL2218 Class-4 hail-resistant rating and are impervious to hailstones as large two and a half inches. That’s bigger than a billiards ball!
Are metal roofs safe in a lightning storm?
Yes! A metal roof isn’t any more likely to attract lighting than any other roofing material. Research shows that lightning is attracted to the tallest surrounding objects that have a direct path to the ground, regardless of that object’s composition. Since your home doesn’t have a direct path to the ground (like, say, a tree), lightning is not attracted to it. In other words, a tall tree in your yard is more likely to attract lighting than your metal roof. Even then, the odds are miniscule that a bolt of lightning will hit anywhere near your home.
In actuality, a metal roof is SAFER in lightning storms. Should lightning strike your home, metal roofing won’t combust like wood, which helps prevent the chance of a fire. The metal also acts as a conductor for the lightning, allowing it to pass to the ground while keeping your home safe.
Does metal roofing really protect my home from fires?
Not only does metal roofing not burn, but it also helps prevent fire from spreading to the rest of your home. Unlike wood roofing, metal roofing will not provide a way for fire to spread. And for fires that originate outside the home, metal roofs don’t give floating embers fuel to burn if said embers land on the roof.
What kind of maintenance do metal roofs require?
Aside from periodic rinsing with a hose or pressure washer, metal roofing needs virtually no maintenance. Since metal is much stronger than asphalt, you won’t have to worry about leaks, corrosion, and replacing shingles. Metal roofs also resist algae growth!
Do metal roofs rust?
Your new metal roof will be rust-resistant if your roofing contractor knows what they’re doing. Metal does indeed rust. But special processes and coatings are implemented to ensure metal roofs will NEVER rust. In addition, metal roofing does not absorb water, which is the biggest reason for rust development.
