NAILS OR SCREWS? HOW TO INSTALL A GOOD ROOF
Buying good roofing sheets is not just enough and does not guarantee that your roof will last through its intended lifespan. It is important to consider the kind of fasteners you will use to install the roof.
Is it better to use nails or screws during the installation process? What is the best fastener for your new roof cover?
Fasteners are used to connect your roofing sheets to the building through the trusses. It is important to select the right fastener in order to ensure that the installation is strong enough and is protected against external factors such as wind and rain.
Traditionally, most people used nails to install roofing sheets. This can be attributed to the fact that nails are relatively less costly and easier to install as they only require a hammer as opposed to an electric drill often needed while using screws.
Nails are not recommended especially for residential and commercial steel roofing solutions. This is because during different weather conditions, the roof tends to expand and contract. This in turn creates a 'pull-out' effect on the nail used in the installation. Ultimately, this leads to a gap on your roof and this eventually leads to leakages. Nails serve a better purpose when used for other construction applications.
Screws differ in terms of material, composition, size and shape. The best screws for steel roofing applications need to have the same properties as the roofing sheets to be used. In the case of MRM roofing sheets for instance, one would need to use Fixtite screws which are coated with a Zincal protection layer, similar to the one found on MRM roofing sheets.
Screws are often stronger than nails and have greater resistance to the pull-out effect often caused by different weather factors. They are especially necessary in high-pitched and steep roofing applications which are common on most residential applications. Screws may sometimes seem more costly or difficult to install as they require an electric drill. However, the cost is eventually worth it as it saves your entire roofing system which would otherwise be expensive to replace.
Fasteners should not be too tight on the roof. Room should always be given for expansion and contraction. In some cases, the wrong choice of a fastener may lead to nullity of the warranty on the roofing sheets. To ensure that your warranty is guaranteed, ensure you use the the manufacturer recommended fasteners.
