Tile Roof Wind Resistance

Some metal roofing brands make products specifically designed for hvhzs that withstand winds to 160mph.

Tile roof wind resistance.

In general square hexagonal and octagonal floor plans perform the best. It all depends on the quality of the chosen material and the amount of the resistance against the wind. Concrete marley eternit tiles are best for wind resistance and due to the weight tradesman rarely nail them down so i suggest that due to the exposure to strong winds ensure each tile is securely nailed down also a smooth finish tile rather than a rough finish would make it more difficult for moss to stay on the tile as there isn t much for it to grip onto but as added protection the roof tiles can be treated with anti fungicide wash. These floor plans increase wind resistance.

Wind resistance in regions prone to tornadoes hurricanes or extreme winds roof tile provides one of the best defenses against wind related property damage. Uplift tas 108 95 wind tunnel char as well as. Concrete and clay tile roofing resists hurricane force winds. Use findings to evaluate fbc 1609 5 3 and tas 101 95 mech.

Even when well at tached they can be easily broken by missiles. Tile roofs are very vulnerable to breakage from windborne debris missiles. This wind uplift test in progress shows a system under pressure. For the material that covers a flat roof wind resistance is less critical and the material tends to have negligible impact from salt spray.

The main wind force resisting systems of a building include rigid and braced frames roof and floor diaphragms shearwalls and the anchorage of roof and wall framing. Develop a wind load model for low medium and high profile roof tiles to compute pressures and attachment forces 2. The cost of the roofs with a wind resistance is higher than the average one. If a tile is broken debris from a single tile can impact other tiles on the roof which can lead to a progres sive cascading failure.

Natural air ventilation under the tile created by its high porosity and installation techniques used help to relieve wind stress. Available in shingles shakes tiles and panels stone coated roofing materials offer 120mph wind resistance and excellent durability. Low resistance cost about 1 000 dollars extra and the high resistance about 3 000 dollars. It s also a good idea to have a 30 degree sloped hip style roof with multiple slopes for the best possible performance.

While this article is focused on wind testing fm approvals also tests roofing systems for resistance to interior and exterior fire exposure hail resistance and long term weather resistance as well as other physical properties.
