 How to stop a roof tile how it is being blown away -2

Wind pressure is a common cause of tiled roof failure. When the wind moves over the roof, an upward force acts, roof The tiles get rattled or they are completely removed.

In contrast to the general way of thinking, roof tiles are not "blowing away" the roof. When the wind moves over the roof, the wind is upward and the tiles are sucked up. In order to build a safer roof system, it is important to understand the distinction of this minority. Lifting the tile upwards and fixing it is the key to keep the tile on the roof.

When the wind moves over the roof, the air pressure at the top of the roof will drop. At the same time, the pressure under the roof increases. An increase in pressure in the loft space results in a positive pressure on the roof tile. The negative pressure above sucks up the tile and lifts the tile's tail. The lower the pitch of the roofing, the higher the power.

If the tiles are being blown away rather than being blown away, the old way of tiling the roof may not be the best. Traditional roof tiles are nailed or nailed to the head and top of the tile. This fixes the tile against gravity, but has little effect on upward tile lifting. The only thing that fixes the bottom of the tile is the weight of the tile.

In the UK exam, it has been proved that roof tiles are hanging or fixed on the bottom, tolerate five times the power of the head nailed roof tile. Tiles can be clipped or wired to ensure that the tail is fixed against wind bumps. This also stops the annoying rattling and chattering associated with the roof where the wind blows from time to time. Chattering occurs when a tile is lifted by a wind vortex and falls. I prefer to use silicone beads between tile courses and act as a second line of defense against tile chatter.

It is important to note that modern roofing tile clips must be installed correctly if effective. The tile clip is usually nailed close to the interlock channel. There is a risk of damaging the tile, so there is a tendency to move the nail too far from the interlock. The clip must be placed at right angles close to the tile. Please make the roof clip firmly lie down so that the tile is not loose. In my opinion, the old system wiring the bottom of the tile is better than the modern clipping. The wire is fixed to the support baton between the tile's bottom eyelet and the tile. This has the effect of tightening the tile. I re roofing the roof over 50 years old and the wire is still tight.

The most important roof component in preventing wind damage is the roofing felt. The roofing felt or the club is placed under the baton before the tile is fixed. The main function of melting all roofs is to prevent wind damage. Paper waterproofing is far less important than the ability as a wind barrier. The sink prevents the pressure rise inside the loft and prevents wind blowing out. It is necessary to firmly fix with 150 mm overlap. To prevent wind movement between the seats it is necessary to place an extra baton at the point where the sheets overlap. If the felt is not correctly fixed, the wind force concentrates on the weak point causing more problems.

All ridges and waisted tiles must be mechanically fixed in a place sensitive to strong winds. With covered mortar alone, you should not rely on fixing these tiles. When the bond between the tile and the mortar is broken, the tile functions moderately. They need to nail, clip, or wire.

The areas submitted most lightly to the wind uplift are eaves, ridges and ridges. In these areas it is prudent to pay special attention to fixing the tiles. Nail and clip all tiles around.

By taking a little time at the installation stage, the roof tile will be kept safe during stormy weather. The extra cost is surpassed by saving maintenance and heart.
