When selecting a reliable flashing for your tiled roof, the RES 3 Silicone Flashing from National Flues stands out due to its superior design and durability. This comprehensive guide will provide all the information you need to make an informed decision, address common concerns, and illustrate how to optimise your roofing project with optional accessories.
Overview of the RES 3 Silicone Flashing
The RES 3 Silicone Flashing is engineered to provide an effective waterproof seal around external pipes. Its robust build, which includes a lead-free aluminium base and a high-quality silicone rubber upstand, ensures performance even under extreme temperature conditions. The flashing is tailored for external pipes with diameters from 275mm to 450mm (11-18 inches) and is optimally designed for pitched roofs between 20° and 45°. This makes it an ideal solution for many residential and commercial installations.
Key Features and Benefits
Temperature Resistance: One of the most impressive attributes is its ability to withstand temperature extremes ranging from -74°C to 260°C. This ensures that your flashing will perform reliably regardless of seasonal shifts or unexpected weather events.
Durability and Longevity: The RES 3 Silicone Flashing is designed for long-term use, with a silicone rubber upstand that lasts up to 20 years. This quality means fewer replacements and lower maintenance costs over time.
Easy Installation: The clever pull tab design, complemented by the smooth tear grooves, significantly reduces the complexity of installation. There is no need for precise cutting, making the product user-friendly for both professionals and DIY enthusiasts.
Eco-Friendly Materials: The flashing is built using a lead-free aluminium base, which supports environmentally responsible building practices without compromising on strength.
Installation Process
The installation process for the RES 3 Silicone Flashing is designed to be as straightforward as possible. Begin by preparing the roof surface, ensuring it is free from debris and moisture. Using a pair of pliers, size the pull tab, then gently tear along the pre-scored grooves if minor adjustments are required. Apply a suitable silicone sealant along the edges of the flashing before fitting it securely around the external pipe. Due to the integrated 20° pitch design, the flashing conforms easily to various roof angles, ensuring a robust and weather-resistant seal.
Addressing Common Objections
When considering a flashing product, you might have several questions:
Is it compatible with my roof?
Absolutely. The RES 3 Silicone Flashing is compatible with tiled roofs, including those with steep pitches up to 45°. The built-in 20° pitch design ensures it fits seamlessly, regardless of the roof’s angle.
Will it handle extreme weather conditions?
Yes. With a temperature tolerance from -74°C to 260°C, you can trust that this flashing will perform reliably in all weather conditions, safeguarding your roof against the harshest climates.
Is the installation process complicated?
Not at all. The intuitive pull tab design and pre-scored tear grooves simplify the installation process. Even those with limited DIY experience can install this flashing with minimal effort. For more challenging installations or additional peace of mind, professional assistance is always recommended.
What about additional accessories?
While the RES 3 Silicone Flashing is a complete solution in itself, you may want to explore optional accessories to further enhance your roofing project. Consider silicone sealants, fasteners, or complementary flashing profiles that might offer additional reinforcement or aesthetic value. Searching for these accessories can help tailor your installation to your specific needs.
Optional Accessories and Customisation
Smart installers often enhance their flashing solutions by pairing them with select accessories. For instance, using premium-grade silicone sealant not only improves the bond but also enhances weather resistance. Fasteners designed for aluminium can secure the flashing without causing damage to the roof surface. Ensure that when you are shopping for optional accessories, you opt for products that complement the high standards of the RES 3 Silicone Flashing.
