Roofing is, without a doubt, one of the most important aspects of your home's exterior. Your home's roof gives it shape and helps to improve its appearance. Because it is located at the top of the house, it also serves as the first line of defense against the elements. A solid and stable roof prevents rain, hail, sleet, and snow from entering your home.
Roofs, however, are not impervious to everything. Natural disasters such as hurricanes and other high-wind storms can cause damage to your roof. When this happens, your home is no longer protected from the elements, and entering rain and moisture can cause wood rot, mold, and mildew growth, all of which can cause further damage to your home.
That is why building codes require wind-rated roofing materials. This is due to the fact that in high winds, some materials may be lifted or torn from the house. As a result, homes in hurricane-prone areas will need to be built with materials that can withstand higher wind speeds than the rest of the country. This includes areas along both coasts where wind speeds exceed 115 miles per hour. You want to make sure your roof can protect your home throughout the storm in those areas. The materials listed below are either rated or can be rated for high wind velocity.
Metal roofing is quickly becoming one of the most popular building materials in the United States. It is extremely durable and long-lasting, and it is available in a variety of styles, colors, and materials. Some metal roofs can easily last more than 100 years with little maintenance. They are also flame retardant and wind resistant, with a wind resistance of up to 140mph. This makes metal roofing an excellent choice for any region of the country, including those prone to hurricanes and other natural disasters such as wildfires. Metal roofs are also relatively environmentally friendly. Most can be made from recycled materials and recycled at the end of their useful lives. Metal roofs can also be painted in reflective colors to create cool roofs. Because many hurricane-prone areas are also in hot climates, a metal roof can be an excellent choice for keeping your home cool.
Depending on the type and style, metal roofs can be more expensive than other materials. Some metal roofs should not be used near the coast, regardless of wind resistance, because the salty environment can contribute to corrosion. Stone-coated, aluminum, zinc, and copper roofs are therefore the best options. A metal roof can cost between $18,000 and $30,000 to install, which is more than some shingle roofs but less than tile and other wind-resistant materials.
Asphalt shingles are another widely used roofing material in the United States. This is a less expensive roofing material, but it does not last as long as metal or tile roofs. It's critical to understand that there are numerous types of asphalt shingles. The cheapest material, 3-tab shingles, has wind resistance of only 60mph, making them an unsuitable choice for hurricane-prone areas. Architectural shingles or laminated shingles, on the other hand, can withstand winds of up to 150 mph.
Architectural asphalt shingles are more substantial than 3-tab shingles. They are more durable and can last up to 50 years if installed and maintained properly. However, you should check for wind resistance because it varies by brand and shingle. Some shingles may be hail-rated, but others are not, and if there is hail in the hurricane, it can damage the shingles and cause leaks weeks or months later. Similarly, some architectural asphalt shingles resist algae growth, while others do not, resulting in a higher overall maintenance roof. Asphalt shingles do not last as long as other roofing materials such as metal and tile. They are, however, the least expensive option for hurricane-resistant materials. They can also be found in a variety of colors, including some that can be used for cool roofing in hot climates.
Architectural asphalt shingles range in price from $9,000 to $18,000, depending on the quality and rating.
Tile roofing is a popular choice along both coasts and in hurricane-prone areas. Originally, tile roofing was always made of clay and was popular due to its durability and longevity, especially in windy areas. Because clay roofs are heavy, newer tiles on the market mimic that durability and wind resistance without the weight. Concrete, metal, and composite/synthetic tiles are examples. Both concrete and clay tiles can withstand winds of up to 150 mph, making them ideal for use in high-wind areas. Tile roofs are, in fact, one of the most popular roof types in Florida. Tile roofs can be coated with reflective materials to provide cool roof options, increasing their popularity in hot climates. They may also be made with some recycled material, depending on the material you choose, making them more eco-friendly in that regard. Tile roofs are also flame retardant, making them an excellent choice in wildfire-prone areas.
Depending on the material, tile roofs can be costly. Some materials, such as clay, require a lot of upkeep. They must be removed on a regular basis so that the underlayment can be changed, and they may be damaged if walked on. However, newer materials are more durable, and most tile roofs can last up to 100 years or more if properly maintained.
The average tile roof costs $19,000 to $35,000 to install, making it the most expensive of the hurricane-proof roof options.
When attempting to make your home hurricane proof, you should consider more than just the roofing material.
The pitch and shape of your roof can also have an impact on how well it performs. The more slopes a roof has, the more resistant it is. As a result, a house with an octagonal or hexagonal roof would be the best for withstanding winds. This would imply an octagonal or hexagonal home, which are uncommon.
As a result, the best roof is a hipped roof with four distinct slopes. Furthermore, the ideal roof slope should be 30 degrees. This pitch prevents wind from getting under the roofing material and causing liftoff.
Finally, pay close attention to any areas on the roof where pressure could build up. Ideally, wind should simply pass over your house. As a result, if something gets in the way, pressure can build up, causing that section to lift or break. Ridge caps, corners, and eaves may be especially vulnerable. It is best to take extra precautions when installing these areas to ensure that they are not damaged during a hurricane.
The best thing you can do is discuss your expectations for a hurricane-proof roof with your roofing contractor. They can also help you meet local and state building codes for hurricane protection based on where you live, as well as advise on their own best practices and hurricane protection suggestions. Then, no matter which of these materials you choose, you'll have the peace of mind of knowing that your home is protected from hurricane damage.
