Wind pressure is a common cause of failure for tile roofs. When the wind moves over the roof, which produces the lift caused the tiles to be removed completely or rattle.
Contrary to popular belief, no tiles are "wiped out". The wind exerts a force upward as it goes through the roof, so that the tiles are drawn. It 'important to understand this distinction well, to build a solid roof. Fixing tiles on topLift is the key to keeping the tiles on the roof.
As the wind passes over the roof surface, causing the air pressure on top of the roof to reduce. At the same time increasing the pressure under the roof. The increase in pressure inside the attic leads to a positive pressure on the tiles. The above negative pressure causes the tiles to be sucked upward, lifting the tail of the tile. The lower the pitch of the roof, the greater the force.
When the tilesbe upward, rather than sucking blown, the old method of laying tiles can not be the best. Traditional shingles are nailed or anchored at the top or the top of the tile. This ensures that the tiles against gravity has little influence on raising the tiles. In fact, the only thing is to ensure the bottom of the tile, the tile's weight.
Testing in the United Kingdom have shown that a truncated or tiles fixed to the bottom can be 5 times the strength to withstand a head nailedTiles. Tiles can be cut or cable, make sure the tail is secured against lifting the wind. This also stops the annoying rattle or chatter sometimes associated with wind swept roofs. The chatter occurs, can be lifted and tiles fell from the turbines. I prefer to use a drop of silicone between the courses of tiles to act as a second line of defense against talking tiles.
It 'important to note that modern tiles are properly installed clips have to do, if you want to have any effect.Tile clips usually are nailed near the canal lock. Because of the risk of damaging the unit, there is a tendency for the nail to move too far away from the lock. The clip should be at right angles in the vicinity of the tile to be placed. The roof should be built-in clip securely to the tile to prevent loosening. In my opinion, the old wiring system of the lower panels is better than a modern cut. The wire connected to an eyelet at the bottom of the tile and betweenTile courses to support the line. This has the effect of suppressing the tile. I re-wired roofs that are more than 50 years and is still the terminal wire.
The main component umbrella when it comes to storm damage prevention, the roofing felt. Felt cover behind the first placed under the direction of the tiles are fixed. The primary function is to hear the cover to prevent wind damage. The estate of the paper is far less important than theirSkills as a windbreak. The membrane covering prevents the increase of pressure inside the loft and prevents wind lift. It must be securely fastened with 150mm overlaps. An additional line should be at the point where the leaves are placed to avoid overlap between the leaves travel wind. If the feeling is not properly protected, the wind force on the weak point will cause more problems by fire.
All the ridges and hip must be mechanically fixed in areas with wind speed. Coverage Malta aloneshould not be relied upon to keep the tiles up. Once the connection is broken between the bricks and mortar of the tile may come off. They should be nailed, wired or cut.
Areas that are more easily given to the wind will lift, docks eaves and ridges. In these areas you should take extra precautions with the installation of the tiles. Nail Clip all the tiles and around the periphery.
A little 'more time at the meeting will be taken to ensure that the tiles stay in heavyWeather. The additional costs through savings in maintenance and piece of mind prevailed.
