Roofing fasteners are specialized screws or anchors used to secure roofing sheets, panels, and components to structural frames. They include self-drilling screws, metal screws, polycarbonate screws, and more — each engineered to match specific materials and load requirements.
Exposed roof fasteners should be sealed using high-performance silicone or MS polymer-based sealants. Products like our Roof Sealant ensure a watertight bond while resisting UV rays and weather conditions.
Roof screws typically last 15–20 years. However, in harsh environments (coastal/humid), check every 5–7 years for corrosion or washer degradation.
The best fasteners for metal roofing are self-drilling metal screws with EPDM washers, like our Metal Screws for up to 12mm steel. They provide maximum strength and leak resistance.
It’s not recommended. Reusing screws can compromise grip strength and sealing. Always use new, rust-protected screws for reliable performance.
Yes, high-quality roofing screws are waterproof when paired with EPDM washers. Our Stitching Screws and Wafer Head Screws come with top-grade sealing washers.
Replacement cost varies based on roof size and material. On average, ₹10–₹15 per screw (including labor and material).
No. Gluing screws compromises structural integrity and is unsafe for roofing or load-bearing applications. Always use certified fasteners.
For roofing and construction, screws are superior. They provide mechanical grip, pull-out strength, and long-term durability.
Use slightly larger screws or wood inserts for timber. For steel, switch to a screw with higher thread count like our CSK Head Screws.
Use self-drilling metal screws or structural adhesives. For heavy-duty fixing, choose our Drills Up to 12mm Screws.
Yes, when installed correctly with quality washers. Our screws with DEKS TrueBlue EPDM washers ensure watertight performance.
Absolutely. Replace corroded or damaged screws with compatible self-drilling screws for optimal safety and performance.
Yes. Our screws are made from case-hardened carbon steel and tested under AS3566-2002 Class 3 standards.
With proper installation, 15–20 years. In coastal or industrial environments, use screws with special rust-resistant coatings like our Rust Shield Coated Screws.
Generally, 20–26 screws per standard 3.5m sheet. Spacing depends on wind zone and panel width.
Self-drilling screws with carbon steel core and multi-layer coating are strongest for structural roofing.
Roofix is trusted across India for durable, rust-resistant, and high-load self-drilling screws engineered for steel and timber structures.
Globally, companies like Hilti, Würth, and ITW dominate. In India, Roofix is a trusted choice for infrastructure-grade fasteners.
They are made by cold-forging carbon steel, threading, and applying protective coatings.
