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.
What type of roof is more susceptible to damage by high winds than any other type?
For wind protection, you want a hip roof that has four slopes, pitched ideally at about 30 degrees. The idea is that more slopes will handle high winds better, so anything more than a two-slope gable roof will be more resistant to wind damage.
What shape of roof is most resistant to hurricane winds?
Shape of the Roof
The most hurricane-resistant roof that engineers have developed features a hexagon or octagon shape. Multi-panel features reduce wind load. If a hexagon or octagon doesn’t appeal to your mind’s eye, opt for a 4-slope hip roof. Multiple slopes perform better in high wind situations.
What is the best roof for high winds?
BEST ROOFING MATERIALS FOR HIGH-WIND AREAS
- FIBERGLASS ASPHALT SHINGLES. In the past, organic asphalt shingles were commonly used, but they stopped being manufactured in about 2008, largely because they aren’t great for the environment and they aren’t fire-resistant. …
- METAL ROOFING. …
- CLAY TILES.
Which roof can resist heat rain and wind?
Building a 4-slope hip style roof has been found to lessen the load of the wind on the house. The hip style roof can stand up to high winds when a storm comes. Another thing to think about when designing your roof is to limit the length of the overhanging around it, keeping it to no more than 20 inches.
How strong does wind have to be to knock down a house?
How much wind does it take to destroy a house? Winds in the 70 to 80 MPH range can cause serious structural roof damage on houses and secured outbuildings and mobile homes. Winds of 90 MPH or greater can totally destroy even secured mobile homes and buildings.
How strong does wind have to be to knock down a person?
Knocking you down would take a wind of at least 70 mph. The terminal velocity, which is the wind speed (falling speed) where the force of the wind equals the force of gravity, for a person is about 120 mph — that would likely knock you down.
Can houses survive a Category 5 hurricane?
A house made of plastic soda bottles can withstand winds twice as strong as a Category 5 hurricane.
What is the strongest roof shape?
Pros: Hip roofs are one of the strongest designs for a roof. The inward slope on all four sides of a hip roof makes it an excellent design for both high wind and snowy areas. These designs also allow for more ventilation and grand vaulted ceilings or attics.
What wind speed can a roof withstand?
Most modern shingle roofs are rated to withstand 90 mile-per-hour winds, although there are roofing products available for hurricane and tornado-prone areas that can withstand winds up to 150 MPH.
Which roof is best for hot climate?
Better options for homeowners in warm climates are metal, slate, clay, or rubber shingles.

- Slate roofing is made of stone, it is impervious to weather, sun, heat, and cold.
What kind of roof is best for hurricane?
It is best to protect your home with a metal roof when it comes to hurricane preparedness. Metal roofs are built to withstand winds of up to 160mph. Plus, it won’t blow away in pieces that become potential projectiles, which is what shingles do when they come loose.
What roof pitch is 30 degrees?
What roof pitch is 30 degrees? A 30° roof pitch is roughly the same as a 7/12 roof pitch. To convert from degrees to the American ratio: Find the tangent of the angle, tan(angle).
What color roof is the coolest?
Since dark surfaces are better heat absorbers, traditional cool roofs are white. Berkeley Lab research has demonstrated that raising the solar reflectance of a roof from about 20 percent (dark gray) to about 55 percent (weathered white) can reduce cooling energy use by 20 percent.
What type of roof is the coolest?
Cool metal roofing is a popular cool roofing material, as it can offer more than twice the solar reflectance of traditional asphalt roofing: up to 70% when paired with a colored reflective coating. Compared to the 30% solar reflectance of asphalt shingles, that’s a dramatic difference.
