Master Flash Silicone Roof Flashing
Description and Purpose
Master Flash is a universal roof flashing designed for quick and reliable sealing of the chimney passage through the roof. Unlike rigid metal flashings, this product is made of heat-resistant silicone on a flexible aluminum base.
Thanks to the plasticity of the aluminum flange, the flashing easily molds to the shape of any roofing material: metal tiles, corrugated sheeting, ondulin, or bitumen shingles, ensuring a tight fit.
Key Advantages
- Universal fit: You don't need to match the product to the complex wave profile of your roof. The soft base simply "molds" to the surface by hand pressure.
- Easy installation: An ideal choice for DIY installation. The cone is cut with a knife to the required pipe diameter, pulled over the top, and fastened to the roof with self-tapping screws using sealant.
- Durability: Silicone is resistant to UV radiation, precipitation, and temperature changes (working range from -55°C to +185°C).
Models and Specifications
The table shows the ranges of outer pipe diameters that the flashing can fit.
| Model | Roof Pitch | Base Size | For Outer Pipe Ø |
|---|---|---|---|
| Master Flash 1 | 0° – 15° (Flat / Low slope) | 425 x 425 mm | 180 – 275 mm |
| Master Flash 2 | 15° – 45° (Pitched) | 650 x 650 mm | 200 – 280 mm |
Important Limitations
- For Sandwich Pipes Only: The flashing is designed for contact with surfaces up to +185°C. It can be installed only on insulated (double-wall) chimneys. Installation on a hot single-wall pipe is strictly prohibited (risk of melting and fire).
- Sealing: During installation, be sure to use roofing sealant between the flashing base and the roof before driving in the screws.
Alternatives
If you require a rigid solution to match the roof color or if the slope angle is greater than 45°, consider classic stainless steel flashings:
