By definition, aluminium flashings is a strip of steel or aluminium that is placed on a roof to help seal the joint between the roof timbers. Aluminium flashing does not have the same durability and strength as that of other materials used to fasten flashing onto the roof. It also has a tendency to corrode and deteriorate at a much faster rate than other flashing, which can make it more susceptible to cracking. If you are considering installing aluminium flashing on your roof, you may find that it is simply not an option in your situation.
Metal Flashing Choices
Roofing nails can be used to fasten flashing onto the roof of any building. However, they often come with a higher price tag due to the labour involved in removing them and the cost of specialised equipment to remove them once they have been used. They also have the potential to break off and become dislodged, creating a safety risk if someone was to fall from the roof. Not only is this a risk for the people who were working on the roof, but it can also pose a risk to anybody who could trip or fall if they were unable to gain access to the roof in the first place. Ultimately, roofing nails are not a cost-effective solution to your aluminium flashings problem.
Alternatively, aluminium strips are often used to fix the flashing on the roof. Aluminium strips are available in a wide range of sizes and thicknesses to match the specific needs of your particular construction. They are incredibly strong and are the same as that used in many of the world’s most advanced aeroplanes and rocket boosters. As well as being highly durable, they are also waterproof and insect proof, making them perfect for use in the most demanding industrial conditions. When purchasing aluminium strips, you should always ensure that the length you require is adequate for the roof space that you are requesting it to cover. In cases where there is not enough space, or where you wish to extend the length of the flashing, it is possible to buy pre-fabricated sections, which can easily be bolted together and joined at the same site as the flashing.
