How to Apply Silicone Sealant for Dektite Roof Flashing
The Silicone for Dektite Roof Flashing is designed to ensure a durable, weatherproof seal between the flashing base and the roof surface. When correctly applied, it enhances water resistance, accommodates roof movement, and prolongs the performance of rooftop penetrations.
Step 1: Prepare the Pipe and Flashing
- Use sharp tin snips to trim the Dektite cone to match the pipe diameter.
- Lightly lubricate the pipe with water to assist the cone in sliding smoothly into position.
Step 2: Position the Flashing
- Gently lift or turn back the flexible base flange of the Dektite flashing.
- Apply a continuous bead of silicone along the underside of the base, following its outer edge.
Step 3: Secure to Roof Profile
- Press the base firmly by hand against the roof, ensuring full contact with the sealant.
- Smooth out any folds or creases to maintain even compression and watertight adhesion.
- Do not overstretch the base – allow some flex to absorb thermal expansion and roof vibration.
Step 4: Mechanical Fixing
- Secure the flashing using self-sealing fasteners or sealed pop rivets, starting from the centre outwards.
- This ensures a uniform seal and prevents air gaps.
- For complex profiles or steep roof pitches (up to 45°), install the flashing on the ‘diamond’ or straight edge to maintain a tight fit.
Step 5: Final Inspection
- Check all edges to confirm full adhesion and coverage with silicone.
- Apply extra sealant to any transition points or fastener heads if needed.
- The sealant is now ready to deliver long-lasting protection against water ingress, wind uplift, and temperature fluctuations.
Always use our approved Dektite silicone with premium roof flashings to maintain full waterproofing integrity and product warranty. It’s formulated to bond securely with metal, polycarbonate, and roofing membranes in all Australian climates.
Caveat: The product description and datasheet on this page may not be the most updated version. Please refer to the user manual coming with products if there are conflicts.
Before application, thoroughly clean the roof surface and pipe penetration area. Cut the Dektite flashing cone to fit the pipe snugly. Apply a generous and continuous bead of silicone around the underside edge of the silicone roof flashing, pressing firmly onto the roof surface. Smooth out excess silicone to create a waterproof seal and ensure full coverage. Allow adequate drying time as indicated on the packaging (usually 24 hours) before exposure to weather conditions.
Yes, the silicone provided by Solar Rains is specifically formulated to withstand extreme temperatures, maintaining excellent elasticity and sealing properties from as low as -70°C to as high as +230°C. This wide temperature tolerance ensures reliability in diverse climatic regions, including hot desert-like environments and cold alpine conditions.
Store unopened silicone tubes in a dry, cool place away from direct sunlight. For partially used tubes, ensure the nozzle is tightly sealed or covered to prevent curing within the tube. Optimal storage temperatures range between 5°C to 25°C. Proper storage extends shelf life and maintains the product’s consistency for future use.
Absolutely. The Silicone for Dektite Roof Flashing from Solar Rains offers exceptional adhesion to a wide range of roofing materials including metal roofs, concrete tiles, terracotta, composite shingles, and asphalt-based materials. Its universal compatibility makes it ideal for professional roofing projects and DIY home improvements alike.
This high-quality silicone typically retains its sealing properties for upwards of 20 years under normal environmental conditions. It is specifically engineered for long-term stability, providing outstanding resistance against UV radiation, ozone degradation, and temperature extremes. Routine inspection and minimal maintenance ensure prolonged effectiveness.
While applying silicone, it is advisable to wear gloves and protective eyewear to prevent skin and eye irritation. Ensure adequate ventilation in enclosed spaces to minimize exposure to fumes during application. Wash hands thoroughly after use and avoid ingestion or prolonged inhalation of fumes. Always follow the detailed safety instructions provided on the silicone packaging for a safe installation experience.

Sandra P –
Good product, but delivery was a bit longer than expected this time. Still, I’ll keep buying from them
Christa Pitman –
The silicon is exactly what I needed for a roof job, no complaints at all
Peter –
Bought for my business, and it’s been reliable. Product does what it says
Wan –
Great value for money
Sandra Parker –
Applied it easily with a caulking gun, and it’s held up through heavy rain and Aussie summer heat. No cracking or peeling. Super happy!
John Francis Armstrong –
Not only does this silicone sealant work a treat (sticks like crazy to both the flashing and roof), but the team at Solar rains were super helpful when I had questions about curing time
Janet Perry-Watson –
It seals fine, but the consistency is thicker than other silicones I’ve used, so it’s harder to squeeze out smoothly. Had to redo a section because it clumped. Once set, though, it’s solid. Maybe better for pros than DIYers.
Tahlia –
This silicon is spot on for sealing Dektite flashings—sets fast, holds firm, and doesn’t go chalky after a few weeks like cheaper ones
