Washers
The importance of washers in a roofing project is sometimes overlooked because they are small and relatively inexpensive. Though they are tiny, good quality washers are an essential art of the roofing system. Poor quality washers can result in enormous cost if they are designed badly or are of inferior quality. The crucial components to a good washer are - design, material, conductivity and traceability.
Here’s why washers make for critical accessories for your system:
- They maintain the steadiness of the roofing system.
- Design: In extreme cases, early breakdown of the washers can cause considerable water damage to the building. If the damage is manageable, it will result in the replacement of all fasteners and seals across the entire roof.
- Material: The premium option, the DEKS washer is EPDM (Ethylene Propylene Diene Monomer) blended with Ozone and UV stabilizers, curatives and processing oils. This is essential for its sealing, conductivity and UV Resistance.
- Conductivity: The DEKS black EPDM washers display a superior performance and are completely compatible with the BHP Color board and Zincalume coated steels. A controlled level of carbon in this product provides superior mechanical properties and superior overall durability, as attested by the Senior Principal Research Engineer at BHP Research.
- Traceability: The DEKS premium range of washers comes marked with the DEKS name or a registered feature, for e.g. the blue line.

Frequently Ask Question (FAQ)
Self-drilling roofing screws are specialized screws that are designed for use in roofing applications. These screws have a sharp point and a drill-like tip that allows them to create their own holes in the roofing material, eliminating the need for pre-drilling and making installation faster and easier.
The main benefits of self-drilling roofing screws include improved speed and ease of installation, reduced need for pre-drilling, improved holding power, and better resistance to corrosion and weathering. These screws also typically have a wider and flatter head that provides a larger contact surface area with the roofing material, resulting in a stronger and more secure attachment.
Self-drilling roofing screws can be used with a wide range of roofing materials, including metal, asphalt, and fiberglass shingles, as well as decking and insulation materials.
Installing self-drilling roofing screws is relatively straightforward. First, make sure that the roofing material is clean and dry. Next, align the screw with the desired location and press it against the roofing material. Then, using a drill or power driver, start the screw and continue tightening until it is fully seated. Be sure to follow the manufacturer’s instructions and guidelines for the specific screws you are using.
Regular roofing screws have a sharp point, but they do not have the drill-like tip that allows them to create their own holes. As a result, they require pre-drilling in order to be installed, which can be time-consuming and challenging. In contrast, self-drilling roofing screws have a combined drill-and-screw tip that allows them to create their own holes, making installation faster and easier.
It is important to choose self-drilling roofing screws that are compatible with the specific type of roofing material you are working with. Some screws may be better suited for use with metal roofs, while others may be better suited for use with asphalt shingles or fiberglass. Be sure to consult the manufacturer’s specifications and guidelines to ensure that you choose the right screws for your project.
The correct length of self-drilling roofing screw to use depends on the thickness of the roofing material and the underlying decking. In general, you want the screw to penetrate through the roofing material and into the decking beneath, but not so far that it emerges on the other side. A general rule of thumb is to choose a screw that is about 1-1/2 to 2 times the thickness of the roofing material.
Yes, self-drilling roofing screws can be used for interior applications, such as hanging drywall or attaching insulation. However, it is important to choose screws that are specifically designed for interior use, as some roofing screws may be too aggressive for use on indoor surfaces.
Self-drilling roofing screws are designed to be used once and should not be reused. Reusing screws can compromise their holding power and increase the risk of leaks or other damage to the roof. If you need to remove a self-drilling roofing screw, it is best to replace it with a new screw.
