Networx: Roof blown off – Lifestyle – The Florida Times-Union

The headlines are impressive: “Easter literally blew up the roof!” “The 86-year-old had blown off his roof!” “Kansas School Roof Blown Up!” When they are accompanied by a video, they are even more impressive. downright scary indeed. Are you wondering if this could happen to you? and how to prevent it.

Let’s find out what happens when a roof is blown off.

What happens when a roof blows off?

During a severe weather event such as a tornado, thunderstorm, or hurricane, high-speed winds cause air pressure shifts that create suction that can literally “raise the roof”. Shingles or even the entire roof can be blown off as if being lifted by giant hands. Although there have been instances where the roof has been temporarily raised and then dropped directly back onto the house, it is usually deposited nearby, potentially damaging vehicles, landscaping, and more, and destroying the roofing material itself.

Fix your roof

If the wind was content to take off just a few shingles, consider yourself lucky. A small clapboard change is usually an easy and relatively inexpensive roof repair. Don’t hesitate, however, because even a small hole in the roof will cause leaks and worse damage over time.

In the case of major damage (more than 30 percent of the shingles are cracked or blown off), you need to weigh up whether a roof repair or replacement is the better option. The age of your roof could be the deciding factor? The service life depends on the roofing material.

If your entire roof has been blown off, you will need to evacuate your house and find a qualified roofer to do an emergency emergency roof repair immediately. A missing roof not only exposes your furniture to the elements, but also weakens the structure of the entire building.

Roof disaster prevention

Maintain your roof. Regularly inspecting the roof for cracks, scuffing, ripples or missing shingles and signs of water damage can reduce the risk of your roof being blown away. Replace the roof when it approaches the maximum service life for your particular type of roofing material. Especially if you live in an area that is exposed to high winds, don’t try your luck by trying to get a few more years off the roof.

Check if your roof is installed according to code or better. This is especially important on older roofs because: 1) if previous homeowners have installed it, you may not know if they hired a reliable, licensed roofer, and 2) local building codes change over time and after a disaster may be updated. For example, after Hurricane Matthew, Florida’s building code stipulated a closer spacing of the roof nails in order to best keep the roofs in place in bad weather.

Properly seal your roof. Make sure the roof edges are properly sealed with a roof cement to prevent storm winds from penetrating underneath and blowing off your shingles. Seal the topping too.

Install a windproof jacket. If you’ve installed a new roof, make sure the sheathing you use is windproof. This sheath is a “second line of defense” that protects against high winds even if the shingles themselves are blown away.

Add roof brackets. These galvanized steel brackets secure your roof to the rafters or trusses of your home to protect it from being blown off in wild weather. The clips are available in buoyancy protection strengths from 300 to 1500 pounds. Choose the installation according to the hurricane threat in your area.

Rope down your roof If you want a hurricane to hit your home, anchor your roof even more firmly. Hold your roof in place with a system of ropes attached to concrete blocks on the ground at both ends.

DO NOT open windows when a strong storm is expected. Snopes has debunked the common misconception that this is helping to equalize indoor and outdoor pressures to keep your roof from blowing off. In fact, opening windows before a storm only exposes your home to more wind and rain damage.
