Redesigned roofs withstand high wind events.
Why gabeled roofs are a problem in high wind.
Wind protection is a house wide concern.
The wind can work its way under the roofing materials and peel them off or it can blow under the soffit and lift the roof right off the structure.
A typical 2 slope gable roof is often times cheaper to build but it allows the wind to catch the roof and it is much more easily blown away.
Other wind damage to a roof includes damage caused by falling objects and debris such as tree branches and downed powerlines.
Building a 4 slope hip style roof has been found to lessen the load of the wind on the house.
Hip roofs four sided roof design are more aerodynamic and inherently more resistant to uplift forces of high wind than gable end and other roof designs.
If wind speeds are very high even new secure shingles can tear away.
But there are things you can do to protect your roof and therefore your home.
2 blow offs tenting reduced wind uplift resistance and billowing.
High wind hazard a gable roof is one of the simplest roofs to construct but it isn t the best choice in high wind areas.
It all depends on the quality of the chosen material and the amount of the resistance against the wind.
Although the dangers of damage to roofs from hurricane winds are vaguely appreciated by most people the nature and distribution of wind forces are not generally understood.
Roofs are very susceptible to wind damage in part because high winds do not hit roofs uniformly.
As strong and sturdy as your roof is remember that it won t be able to withstand high uplift pressures if your doors and windows aren t protected.
Low resistance cost about 1 000 dollars extra and the high resistance about 3 000 dollars.
The cost of the roofs with a wind resistance is higher than the average one.
The hip style roof can stand up to high winds when a storm comes.
And ironically one of the biggest factors in damage to a roof is windblown debris often the debris of other people s failed roofs.
Originally published august 1965.
Where a moderately high wind is expected the cost might increase to as much as 3000.
Leaks are not the only problem that can result from improperly installed flashing.
For those choosing to rebuild rima taher an expert on wind resistant structures has a bit of advice.
Proper installation will only end the damage caused by high winds.
A single storm can destroy a roof in many cases.
Hot bituminous roofs where flashing is poorly attached may experience open seams and laps and ultimately cause blow offs reduced puncture resistance and code issues advises care.
The tornado that stormed through joplin mo on may 22 shredded an estimated 8 000 buildings and stranded desperate families that now must decide whether to rebuild or find a new home.
In high wind areas you may need to spend closer to 5000.
