It only requires a moment to get an Oklahoma tornado to peel off the roof a home. And when the roof is incapacitated, the home is a sitting duck for additional harm, if not total destruction.

Your very best defense: secure the roof firmly into the house and comprise numerous layers of moisture defense.
After are PATH’s recommendations for attaining storm resistant roof:
Construct a Moderately Pitched Hip Roof. Because mid-range pitch roofs withstand strong winds greater than steep roofs, so maintain the roof pitch under 6/12 and larger than 4/12. Flat roofs grow uplift forces on the overhang and therefore are more vulnerable to leaks. During a tornado, this can also prove to be beneficial.
Gable ends are especially susceptible to storm damage, therefore it’s far better to avoid them completely. However, in the event that you have to have them, use a nailing pattern of 8d ring shank nails at 4 inches on center for virtually any panel adjacent to a gable end and include diagonal bracing of the gable wall into the loft floor.
Utilize OVE structural members for roof truss elements or engineered timber girders. Pre-fabricated roof trusses allow for much quicker installation than trusses constructed on site. Prefabricated trusses are equally as powerful as strong wood beams plus they save timber since they’re generally spaced on 24-inch facilities and manufactured using 2 × 4 and 2 × 6. If roof trusses are not accessible or appropriate to your job, use engineered timber. You can find these supplies at any local Oklahoma City home and garden store.
Tie hurricane straps to load-bearing parts. Should you put in hurricane straps on non-load-bearing timber, then you will do nothing to grow the disaster resistance of the home. Connect them to load-bearing walls or bracing instead. Utilize hurricane straps that wrap across the surface of the roof truss or rafter each Fortified for Safer Living criteria ( www.IBHS.org). Each component of a wall assembly ought to be secured together or anchored from the base to the roof to offer a continuous load path, effectively linking the roof to the base.
Insert Baffled Ridge and Soffit Vents. Reduce the number of penetrations in the roof for extra protection. Through-the-roof penetrations, such as attic vents, can blow off in high winds, supplying a hole for water entrance. Baffled ridge vents stop airflow and wind-driven rain from going into the attic through the valve port. Select soffit vents using perforations which are focused close to the outer border to lessen the region that wind-driven rain may enter. They’ll cost roughly the same as vents using uniform perforations. To defy storm-force winds, it is ideal to use plywood or fiber-cement soffit substances and attach them firmly to framing. A timber baffle securely installed within the wall framing within a soffit will considerably reduce water entry to the loft, but it needs to have the ability to withstand powerful air pressure.
Stretch facia board to complete the bottom of the soffit. An effective overhang layout extends the fascia board under the bottom of the soffit by constructing the fascia from a 1×6, rather than the normal 1×4. This produces a drip edge in order that buffeting winds don’t induce the rain across the soffit surface and in the eaves. The extra cost to implement this recommendation is that the gap between the purchase price of 1×4 and 1×6.
Securely attach roof decking. Utilize roof sheathing using a minimal depth of 19/32 inches for extra power in high risk, high-wind zones. Thicker sheathing may also counter sensitivity to overdriving. Utilize a nailing pattern of 8d ring shank nails at 6 inches on center. Don’t attach to principles. Ensure that sheathing is correctly dispersed, letting a 1/4-inch gap between sheets for thermal growth. H-clips can offer this spacing, while adding strength to the flat connections.
Also look at utilizing grid-marked panels, making it faster and simpler to set up sheathing. They cost about $0.85 a 4-foot × 8-foot panel but are very likely to save over that via faster installation with fewer errors.
Tape sheathing seams. Roof sheeting and underlayment can blow off in high winds, in which case the roof tiling may work as a water and wind barrier in the event the seams are taped using a self-adhering asphalt/rubber (modified bitumen) tape that’s at least 4 inches wide.
Instead, consider using a peel and stick roofing membrane merchandise over the whole roof deck. These products are frequently utilized in roof valleys, and supply excellent protection against water intrusion in the event the principal roof covering is ruined. Should you employ the valve, additional underlayment isn’t mandatory, but you have to port the attic or put in rigid insulation across the roof decking in many climate zones to stop winter moisture issues. This underlayment costs about $700 to $1,000 over normal roof felt to get a 2,400-square-foot residence.
Install underlayment properly. Install underlayment per manufacturers’ specifications with approved fasteners. Roofs with a slope of less than 4/12 need two layers of accepted #15 felt underlayment or a constant peel and stick membrane underlayment. All underlayment rows must overlap at least 4 inches. Just one layer of #30 felt could be employed on greater sloped roofs.
For optimal security, use a high heeled, tear-resistant synthetic felt. A discovered underlayment from Grace Tri-flex 30 withstood both Hurricane Katrina and Rita on the LaHouse, that was still under construction once the storms struck. The other roofing felts from the region were shredded.
Use appropriate flashing and beginner strip methods. Install flashing where there’s a shift in the surface airplane or cladding material. It serves the double purpose of channeling water runoff during storm events and offering another degree of water intrusion security.
Flash roof borders using a shingle starter strip (with tabs cut off or specific adhesive starter strips) or a self-adhering ice and water barrier membrane. Don’t use a upside down comforter because of the starter strip. Employ a drip edge to each of roof edges (such as rake). Make sure that fiberglass and asphalt shingles float the drip border strip by at least 1/2 inches to 3/4 inches. Meticulously follow construction code and roofing cladding manufacturers directions.
Put in a breeze- and – impact-resistant covering. Select appropriate end- and – impact-resistant roof coverings and set up each of the manufacturer’s directions. Rated wind- and – impact-resistant asphalt shingles, and standing-seam metallic roofs are great options for storm immunity. Ensure that they meet the criteria for wind resistance (ASTM D 3161 improved or UL 2390) and affect resistance (UL 2218). In warm climates, define light colored or solar reflective roof coverings which consume less heat from sunlight and make the house more energy efficient.
Use appropriate fastener/nailing programs for your end zone. Fastener/nailing schedules often alter together with the merchandise and end zone, so pay particular attention to such details. Consult the manufacturer’s specifications so that attachments are installed to the correct embedment depth into framing members or sheathing. Know about the thickness that you put your own automatic tools. In high-wind zones, raising the frequency of attachments from four to half a shingle will also boost the wind-resistance score.
