Do you live in a region with regular thunderstorms and strong winds and are concerned about how to stop roof tiles from lifting? At roofing mission, we understand your concern. Roof tiles are prone to damage and destruction as a result of inclement weather and powerful winds. Tile lifting is the term used to describe the damage to tiled roofs caused by tiles dislodging and flying off. It also contributes to tiled roof failure.
Strong winds exert an upward force on the roof tiles that builds pressure on the undersurface of the tile. The intense upward force may cause partial dislodgement, which produces a rattling sound or total blowing off the tile, resulting in tile lifting and consequent roof integrity damage.
Tile lifting is a regular occurrence because most roof tiles are designed to resist gravity by clipping from the top. Wind pressure causes the unadhered and loosened bottom end or the tail of the tile to lift. It is a frequent occurrence that causes substantial damage to a house’s roofing system. Repairs can also be expensive. As a result, preventing tile lifting is critical to ensuring a more secure roofing system.
Preventing Roof Tiles from Lifting
Here are some of the tips on how to stop roof tiles from lifting.
- Determining The Cause; Identifying the root cause of any problem is critical before attempting to solve it. Tile lifting follows the same logic. Many homeowners believe that blown-away tiles cause tile lifting. While this is somewhat correct, the underlying cause is the suction of tiles upward owing to pressure buildup; On the roof, there is a pressure imbalance, with the top experiencing lesser pressure and the bottom or underside experiencing more pressure. It is significantly more common on lower-pitched roofs than on higher-pitched roofs.
- Choose Wisely; It is pretty evident that tile uplifting is a common phenomenon in areas with heavy winds. Thus there is a stark contrast in the choice of roofing tiles when you live in such an area. The large and lightweight slates and tiles have an excellent potential for tile lifting when used on roofs; So, using smaller and heavier tiles for your roofs would be wiser. In such circumstances, tiles with screw fixing have also proven better than the nail fixing mechanism. It is also recommended to choose interlocking tiles laced with robust clipping systems.
- Skillful application of roof tiles; Modern problems require modern solutions. Even though tile lifting has been occurring for ages, the primary cause is the failure to deploy innovative solutions. The majority of roof tiles are laid traditionally; The conventional approach entailed clipping the tile’s head or top and leaving the bottom end unhinged. The fact is that the lower end is stable due to its weight, except when subjected to high winds. Roof tile clipping on both vertical ends has been practically proven to be five times more stable against wind-generated lifting forces; Roof shingles are also a creative way of tackling this years-old problem. Adding a layer of silicone bead doubles up the protection against adverse forces of the winds. If your roof tiles make that annoying chattering sound, the modern method of double clipping can also tactfully eliminate that.
- Adequate Clip Installation; Tile clips must be installed correctly to ensure functional adherence and avoid tile loosening. It is critical to insert the tile clip at the right angle. While modern methods work effectively in most cases, they tend to fail in others; The latter performs better when modern tile clips are compared to the centuries-old wiring method. It creates a complicated interlocking that can last for 50 years. Therefore, either install the clip correctly or switch to the conventional wiring method.
- Emphasize on Roof Felt; Roof felt is essential for all roofs, especially if you intend to put tiles or shingles. It serves as the foundation and creates an even surface for applying roofing felt. It also serves as the roof’s backbone, protecting it from wind and water damage. While roof felt serves water and wind protection, the latter is significantly more vital; Because of its usefulness, particularly for wind protection, it is installed beneath batons before tile installation. It acts as a pressure canceling force, preventing negative pressure from causing tile lifting; Even in the case of roofing felt, proper installation is critical. The suggested overlaps are set at 150 mm. Regardless, the overlapping section is deemed fragile and can be secured by installing an additional baton. Inadequately installed felt, especially in overlapping areas, allows for pressure accumulation.
- Fixing and Uplifting; Ridge tiles and slits are in desperate need of reinforcement. The areas most vulnerable to wind uplift include the eaves, verges, and ridges. It becomes critical if you reside in a region with high-velocity winds and want to protect your roof tiles. While mortar is an excellent solution for anchoring roofing tile crest and hip joints, it is insufficient. To ensure full-spectrum protection, use clamps, wires, and nails to secure the mortar.
- Regular Inspections; Weathering and aging are common phenomena even in the most high-quality and handpicked materials. Regular inspection to assess signs of weathering is even more critical in items like the roof tiles that are constantly exposed to the weather. Get your roof tiles inspected by a professional roofer at regular intervals to ensure that there are no loose or poorly clipped tiles prone to lifting by the high-intensity wind.
Additionally, how to extend the life of roof shingles? Discusses tasks the homeowner should and shouldn’t do that are relevant to maintaining tiles in this situation too. Like to avoid making the roofing material brittle in any way;
- Putting pressure on the roof by walking on it often or pressure washing it to clear debris on the roof;
- Layering shingles, tiles, or any roofing material as it will result in its top layers catching the wind and helping it to lift up;
- Securing flashing that could tear off surrounding shingles with enough wind, etc.
Beware of Roof Tiles Lifting
In terms of destruction potential, tile lifting has a domino effect since it leaves the roofing structure open to further harm. It jeopardizes the safety and security of your home by causing damage to the roof. The hefty repairs can also put a significant dent in your wallet.
A little foresight and vigilance can go a long way toward reducing the likelihood of tile lifting. To save money and maintain the integrity of your roof in the long term, it is critical to prevent tile lifting. The ultimate key to preventing tile lifting is to ensure a robust adherence mechanism and an excellent resistance to the lifting forces of the wind, which is achieved by heavyweight tiles.
