Residential properties face the harshest of elements on a daily basis. Most homeowners fear hailstorms, but windstorms are a completely new nightmare that delivers worse damage to any roof. For many reputable and experienced roofing contractors in Edmonton AB, wind damage is likely because of a poor initial roofing installation in any home. However, this is just one factor that helps prevent wind damage. Having the best roof shape for high winds drastically reduces this as well.
You might ask “are gable or typical roof shapes enough to withstand wind damage?” According to one study published in ScienceDaily, a gable roof is one of the best roof shape for high winds. Any roof with a 30-degree slope can sit well and prevent possible wind damage. The study also highlights several installation and improvement factors that reduce the possibility of wind damage.
The Best Roof Shape for High Winds: A Study (Excerpt)
From this work and other studies Taher recommends the following construction considerations for homeowners in hurricane-prone regions.
- A home with a square floor plan (or better a hexagonal or octagonal plan) with a multiple-panel roof (4 or more panels) was found to have reduced wind loads.
- Roofs with multiple slopes such as a hip roof (4 slopes) perform better under wind forces than gable roofs (2 slopes). Gable roofs are generally more common because they are cheaper to build. A 30-degree roof slope has the best results.
- Wind forces on a roof tend to be uplift forces. This explains why roofs are often blown off during an extreme wind event. Connecting roofs to walls matters. Stapled roofs were banned following Hurricane Andrew in Florida in 1993.
- Strong connections between the structure and its foundation and connections between walls are good. Structural failure is often progressive where the failure of one structural element triggers the failure of another, leading to a total collapse. Connections are generally vulnerable but can be inexpensively strengthened. (Read the full study here)
On the other hand, there is no 100% guarantee that using the best roof shape for high winds prevents any form of damage after a hurricane, cyclone, and most especially tornadoes in Edmonton AB. While a strong windstorm makes it easier to spot any roof damage from the curb to your roof, you’ll find it more difficult to spot during typical or slightly-stronger hurricanes.
Nipping wind damage issues in the bud helps you prolong your roof’s lifespan and overall performance. However, this begins with a thorough roofing damage investigation. Even if you have the best roof shape for high winds, consider taking these roof wind damage inspection steps from Dry Home Roofing and Siding.
How Wind Damages Your Roof Despite Having The Best Roof Shape for High Winds
The effect of wind moving over a roof is not uniform. Areas like the corners and perimeter of the roof can be susceptible to higher wind pressures, while the center of the roof might have lower stresses. According to the National Roofing Contractors Association (NRCA), most wind damage to a roof starts on the edge. Anywhere the roofing material is even a little bit loose, the wind can get below it and push it up, thus giving the wind more to grab onto next time and creating a chain peeling effect. This type of wind damage can start very small, but continue to grow over time through repeated exposure to wind.
Once a whole corner of insulation is exposed, rain can get in and start to cause leaks and water damage. Homeowners can avoid this type of wind damage by making sure materials on the edge and corners of their roof are strong enough and in good condition to withstand high winds. (Read the full post)
Knowing is half the battle. Having the best roof shape for high winds helped you bring down roofing or general property insurance premiums. Now, it can help you make a valid claim if it’s accompanied with a detailed inspection.
NRC Roofing and Siding has a great post on what you can do right after a storm and upon inspecting your roof for damages to maximize your insurance claims. Read more below to find out how.
Wind Damage Insurance: The Last Few Steps to Success
One of the first things that you should do (after calling your public adjuster of course) is a wind damage roof inspection starting with the roof inside and out, or have it inspected and locate the damaged spots and assess the extent of the damage.
Next, you or your contractor should mitigate the damage however you can by using tarps or other protective materials – this will be important for your insurance claim later, so you can show that you took the necessary steps in order to not let the wind damage to your roof get worse.
Then, inspect your insurance policy and call your public adjuster to find contractors, get estimates, and plan the next steps.
Again, if you are not comfortable with clamoring around on your rooftop or in your attic, then you can call in professional contractors and inspectors. (Read more)
