Storm Proof Roof has passed three milestone research effectiveness tests.
1) Pop-Off Load Test
During hurricane events a home’s roof can be in a battle of competing forces. When hurricane force winds penetrate a home through windows or doors it’s the weight of your roof deck plus the strength of your fasteners versus the uplift force of hurricane winds. In too many homes over 15 years old the battle of forces is won by the hurricane.
In most homes over 15 years old the roof is a simple plywood deck held in place by gravity and a haphazard pattern of nailing used to fasten the deck to a supporting truss system. When hurricane force winds penetrate a home, uplift forces can exceed the strength of the nails plus the weight of the deck. The result is roof deck "Pop Off." Once pop-off occurs the truss system loses stability and can topple. That’s why roof-deck pop-off is among the leading causes of hurricane roof damage.
Independent tests of The Storm Proof Roof weighting system have been conducted at Florida International University’s Structures and Construction Laboratory (SCL) in Miami. Miami-Dade County – home of the nation’s strictest hurricane building codes – has designated the SCL an official site for determining whether building materials and related products meet the county’s hurricane building code standards.
At SCL the Storm Proof Roof weighting system was tested against uplift forces equal to those of hurricane force winds that have penetrated a home.
The Result
"The Storm Proof Roof was shown to increase the roof deck's resistance to pop off force loads by more than 300%."
2) Wall-of-Wind Test
In 2006 The
Wall of Wind
(WoW) was developed at Florida International University (FIU) in association with the
International Hurricane Research Center
(IHRC). The WoW uses a series of large industrial fans powered by race car engines to simulate hurricane-force winds. The WoW is a testing device to help construction professionals and engineers learn more about the effects of hurricanes on buildings and construction materials.
The Result
"It was observed that no lifting of wind-caused displacement was seen at any stage of the test."
3) Missile impact Test
All houses leak air around windows and doors. That means, under normal circumstances, internal pressures inside a home are slightly negative. This negative pressure helps hold down a home’s roof and keep walls intact. But if an opening is created on the windward side of a house air can rapidly flow in and internal pressure can build forces that push the roof up and the walls out. It’s much like blowing up a balloon.
That’s why protecting vulnerable opening areas like windows and doors from flying debris – or missiles – is critical during hurricane wind events.
Standardized tests developed by The American Society for Testing Materials (ASTM) determine the compliance of an impact resistant system for protecting windows and doors against missiles and hurricane debris. Two standard tests apply to Storm Proof Roof. They are
ASTM E 1886
and
ASTM E 1996. In layman’s terms, ASTM 1886 sets standards for windows, walls, doors and shutters impacted by missiles while ASTM 1996 sets standards for windows, walls, doors and shutters impacted by windborne hurricane debris.
Storm Proof Roof was required to pass the missile impact portions of the ASTM standards. The missile impact test requires Storm Proof Roof resist the impact of a 2 x 4 piece of lumber shot at a speed of 33.3 feet per second (a little more than 23 miles per hour).
At Clemson University’s
Wind and Structural Engineering Research Facility
the Storm Proof Roof was tested against missile impact at 24 mph (6 percent faster speed than required) – and in a 90-degree vertical position rather than the less severe sloped orientation it would normally occupy on a roof.
The Result
"The module resisted three impacts at 24 miles per hour. It is reasonable to assume that impact resistance is more than 24 miles per hour. The Storm Proof Roof water module is constructed from a material with enough toughness to resist a 9-lb. 2x4 impacting both a half-filled and filled chamber oriented in a vertical position. This performance provides assurance that the water modules can resist an impact without leakage when properly installed on a roof deck."
The Storm Proof Roof product can be effective for most any composite, tile or metal roof with a pitch or slope that does not exceed 3 inches of rise to every 12 inches of run.
Each 13 ft. Storm Proof Roof module is just $245.00. An entire system for a typical 2,000 sq. ft. home (10-12 modules) costs from $2,500 to $3,000*. For a typical double-wide manufactured home the cost is approximately $2,000 to $2,500*. A very realistic price to dramatically enhance the safety of your home in a hurricane now and for years to come. Easily stored in a container the size of a trash barrel... you can easily take it with you if you move!
Yes. It was specifically designed to be very simple. Any able bodied person is a candidate for installation and in some cases can be installed from a step ladder. No permits are required.
Usually a simple measurement of the approximate perimeter is all that is needed. A guide will be posted on this website in the future with simple instructions.
A Storm Proof Roof module holds approximately 133 gallons when full. An average size house of 1800 sq. ft. would need approximately 12 Storm Proof Room Modules.
No, if simple instructions are followed. The company has determined through testing that a minimal roof structure should be in place before installation. Please refer to the "Specifications" section of this website.
No. The Storm Proof Roof System was designed to work with maximum effect and is therefore meant as a "temporary" load on the roof. This "temporary" load is safe for up to 2-3 weeks but longer periods of continuous use could lead to roof deflection (bending) or unnecessary loading and structural stresses.
The Storm Proof Roof modules (approximately 12 for 1800 sq foot house) are easily rolled for storage and require very little space in a garage or storage space. A large trash can will work well for storage.
The Storm Proof Roof is made of extremely durable nylon reinforced plastic. The material is UV and mold resistant and if stored and installed properly should last the lifetime of the roof.
If evacuation warnings have been issued, homeowners should leave. The Storm Proof Roof System is designed to protect property only, not lives.
The Storm Proof Roof comes with a limited one year warranty.
For Hip Roof homes modules are place around the perimeter over the bearing walls. To determine the number of modules needed, measure the length of each side of your home and divide each sides dimension by 13ft. The total needed for each side is the total for the house. For a Gable roof measure only the lengths of the roof over the bearing walls, (typically the two longest walls) and divide by 13. For more in information Click Here.
