Screw Distributors is a roofing screw supplier. Our years of experience with fasteners have ensured that we are able to properly advise our customers on their usage and applications. Below, we have included the relevant information necessary for the application and usage of the roof screws that we supply.
There are a few different types of roofing screws that are available. Some are stainless steel screws, or screws manufactured using other materials, that are intended for use with corrugated iron roofs. They are well suited to this task, given that they are built for durability. Screw Distributors are able to supply a few different types of roof screws.
Zinc Yellow Roofing Screw
These roofing screws come with a coating of zinc. Zinc is a very useful material in fasteners, especially within outdoor applications. Offering both abrasive and corrosion resistance, zinc roofing screws are made for the task, able to withstand relatively substantial punishment as well as resisting atmospheric degradation.
Stainless Steel Screws
Stainless Steel screws also offer similar benefits to those with zinc coatings. They offer corrosion resistance, durability and low maintenance, as well as superior strength. This makes them a viable option for their intended purpose. As an added benefit, stainless steel is also 100% recyclable.
Roofing Screw Application and Installation
There is a specific process that must be followed to correctly install roofing screws. Ensuring you have the right colour is one, as this will help in matching the screws to the colour scheme of the building itself. To make sure you are using the correct fastener, stainless steel screws or otherwise, check for the special washer that is built into it. These allow the screws to be tightened at the correct compression against the metal, meaning that the washer is able to properly seal the hole and offer protection against the elements.
The correct installation of the roof screws is as follows:
- Place the appropriate drill bit for the size of the screw into the drill and ensure the drill’s turning direction is set to run clockwise.
- Move the metal or corrugated roofing to the required location, Insert the head of the roofing screw into the drill bit. Then, hold the drill such that the screw sits perpendicular to the surface it must penetrate.
- Drive the screw through the metal and into the wood, keep doing so until the washer on the screw is well seated in the metal and has created a satisfactory seal.
- Once done, inspect the head of the screw. The seat on the washer should be slightly visible on all sides of the screw, but not appear squished or forced out from under the washer.
- If the seat is not visible on the roofing screws, tighten the screw until it is.
By following the appropriate steps, your installation will be completed to a satisfactory standard, at least with relation to the screws. This process remains the same, whether stainless steel screws or zinc ones are used.
Of course, before beginning any installation, proper safety guidelines should be followed. Wear safety glasses, and clean up any metal shavings upon completion to minimise the risk of injury.
