Ohio’s weather can be unpredictable, and tornadoes are a serious concern. These violent weather phenomena can produce winds of over 200 miles per hour, and even weaker storms can significantly damage structures.
If you own a home or business in Ohio, protecting it starts from the top. That means choosing the best roof for tornado protection is crucial. But what is the best roof to withstand a tornado?
Let’s explore some top contenders and the specifics of why they excel in high-wind situations.
Metal Roofing: The Gold Standard in Storm Protection
Many experts agree that metal roofing offers superior protection against high winds and impact from debris. While it would be difficult for any roof to withstand a direct hit from the most powerful of tornadoes, a metal roof’s durability and design make it a standout choice for surviving the gusts on the periphery of a twister or high winds from any storm.
Here are some of the characteristics that make metal roofs so strong:
- Wind Resistance: Metal roofs, particularly standing seam metal roofs, feature interlocking panels secured with screws, creating a robust, continuous surface. This design prevents wind uplift, a common failure point for other roofing materials. The interlocking system creates a seamless surface, reducing the opportunity for wind to “grab” the roofing and pull it away from its supports. Many metal roofs can withstand winds exceeding 150 mph, and some even higher. This is due to the way the metal is fastened to the structure of the home or building.
- Impact Resistance: Metal roofs often achieve the highest UL2218 Class 4 impact rating, meaning they can withstand the impact of a 2-inch steel ball dropping from 20 feet without damage. This is crucial in tornado-prone areas where flying debris like branches, hail, and even larger objects become dangerous projectiles. This rating is very important for insurance purposes as well. Many insurance companies offer discounts for roofs with a high impact rating.
- High Strength-to-Weight Ratio: Despite being extremely strong, metal roofs are relatively lightweight compared to concrete or tile. This reduces the stress on your home’s structure and makes the roofing panels less susceptible to being torn away by high winds. This also means that in the event of extreme damage, the potentially compromised structure of the home has less weight to bear. The lightweight nature of metal roofs also makes them easier to install.
Other Storm-Resistant Roofing Options
While metal stands out, other materials provide good protection with their own unique characteristics, including:
- Impact-Resistant Shingles: Ask your roofer about asphalt shingles with a high wind resistance rating, such as Class H shingles, designed to withstand up to 150 mph winds. These shingles are often thicker and stronger than standard asphalt shingles. Reinforced fiberglass asphalt shingles offer added durability. Fiberglass reinforcement increases strength and resistance to tearing, which is essential in the kind of gusting winds common near tornadoes.
- Concrete Tiles: Due to their weight, concrete tiles are naturally resistant to high winds. Their natural porosity also allows air to flow through them, reducing uplift. In addition, concrete tiles are highly fire-resistant, which can be an added benefit.
The Importance of Roof Design and Construction
When it comes to a roof surviving a tornado, the roofing material is only part of the equation. Roof design also plays a crucial role in wind resistance.
For example, hip roofs, where all four sides slope downward to the walls, have an aerodynamic structure that allows wind to pass over with minimal resistance. This reduces the amount of pressure that the wind can apply to the roof. Low-slope roofs, whose designs minimize the surface area exposed to the wind, also experience less wind pressure. On the other hand, a gable roof, with its large flat sides, is much more susceptible to wind damage.
Securely connecting the roof to the walls is also vital. Many insurance companies offer discounts for homes with reinforced roof-to-wall connections. This can include using hurricane clips or other specialized fasteners.
And, of course, even the best materials won’t perform well if installed incorrectly. Proper installation is critical for wind resistance. That’s why choosing a reputable residential roofing contractor or commercial roofing services provider is essential.
Finding the Right Roofing Professional in Columbus
When considering a new roof or upgrading for tornado protection, it’s crucial to work with experienced professionals. Look for a reputable Columbus roofing company with a strong track record.
Residential roofing contractors with expertise in wind-resistant installations are your best bet. If you own a business, ensure you choose a commercial roofing services company that understands the specific needs of commercial buildings in high-wind areas.
Final Thoughts
What is the best roof to withstand a tornado? Many experts believe metal roofing (especially a standing seam roof) is the best for tornado resistance due to its strength, impact resistance, and secure installation methods. However, impact-resistant shingles or concrete tiles also provide commendable performance in adverse weather conditions.
Keep in mind that your roof design and characteristics, like strong roof-to-wall connections, are as important as the roofing material itself. And finally, be sure to choose a reputable roofing contractor with experience in wind-resistant roofing and proper installation techniques.
