The extra heavy duty stormpro assemblies helps to fortify the opening to withstand extreme wind speeds and flying debris during a tornado. Roofing materials have not been used on concrete roofs on houses constructed on the island of guam over their 50 year history. Because mid range slope roofs withstand strong winds better than steep roofs keep the roof pitch below 6 12 and greater than 4 12. Following are path s recommendations for achieving storm resistant roofing.

Stormpro doors and frame assemblies meet the requirements for fire protection icc 500 2014 and fema guidelines. Roof framing is the next building element of the load path. It is essential in tornado resistant roof design that the roof sheathing and framing are built and sized for the potential. Leaks are rare generally caused by faulty construction practices and are easily repaired.

The round design allows the wind to blow around the home. Sizing of the rafters of a roof s frame must resist the weight of the roof system. Flat roofs increase uplift forces on the overhang and are more prone to leaks. An ef 5 rated tornado can demolish everything in its path.

Tornadoes winds can reach speeds up to 300 mph which is an impossible force for many straight wall buildings to handle. The answer is yes if the home were constructed like a bomb proof bunker with thick walls a reinforced concrete roof and a super strong internal support system to prevent structural collapse. A round or multiple sided home is more resistant to hurricane strength winds. The savings in eliminating conventional roofing materials will also offset the cost of the concrete roof solution.

Here s a basic design for a tornado proof safe. A cat 5 hurricane proof log house is resistant to the winds up to 245 mph. Even some so called tornado resistant homes succumb to their deadly force. The roof framing must also move the lateral loads to the shear walls below.

Few storms make it to ef 5 at the top of the scale. Large but slow tornado strikes kansas. Build a moderately pitched hip roof. Wall logs in such construction have to be made of circular reference glued laminated timber and all other components of the house have to be hurricane resistant.

Before a tornado hit in may of 2013 dan had four metal buildings on his property in marysville kansas.
