Dektite & Silicone PRODUCTS AT SOLAR RAINS

What Are Dektite & Silicone Products?

Dektite and silicone products are essential sealing and waterproofing components in solar and roofing installations. These materials are primarily used for roof flashing, ensuring a tight and durable seal where cables, pipes, or mounting structures penetrate the roof surface.

Dektite refers to a specific type of flexible flashing made from EPDM or silicone, designed to conform to a wide range of roof profiles while creating a watertight barrier. It is widely used in solar installations for sealing around conduit penetrations, racking systems, and other rooftop mounts.

Silicone roof flashing products—such as sealants and weatherproof adhesives—are applied around joints, seams, or fixings to provide additional water resistance, UV protection, and long-term durability.

Why Dektite and Silicone Are Essential in Solar and Roofing Systems

• Weatherproofing: Prevents water ingress at roof penetrations, reducing the risk of structural damage.
• UV resistance: Maintains flexibility and sealing power under prolonged sun exposure.
• Thermal durability: Resists cracking or degradation under extreme temperature shifts.
• Flexibility: Adapts to various roof types—metal, tile, corrugated—ensuring a snug, long-lasting fit.
• Installation efficiency: Quick to apply, requiring no special tools and supporting a professional finish.

Solar installations demand dependable materials to preserve roof integrity. That’s why every mounting point or penetration must be secured using certified roof flashing systems like Dektite and silicone-based sealants.

Types of Dektite & Silicone Products at Solar Rains

At Solar Rains, we offer a selection of dektite and silicone solutions designed for rooftop solar projects across Australian conditions.

1. Dektite Premium Roof Flashing

Flexible, pre-moulded flashings that accommodate various pipe or conduit sizes (typically 0–70mm, 50–170mm, or larger). These are made of weather-resistant EPDM or high-grade silicone, designed for:

• Corrugated or flat roof surfaces
• Use with solar conduit, cable trays, or mounting rails
• Temperatures from -50°C to 200°C
• Pressure-sealed base for maximum leak resistance

2. Silicone Roof Sealants

Our range of silicone sealants is specially formulated for use in PV system installations, offering high adhesion, elasticity, and UV durability.

• Neutral-cure silicone suitable for metals and plastics
• Non-corrosive and non-acidic formulation
• Ideal for sealing flashing edges, screws, and fixtures
• Weatherproof for over 20+ years in exposed environments

3. Mounting Grommets and Flashing Boots

Additional accessories include grommets, collars, and boots made from EPDM or silicone, used for cable entry points or bolt-through mounts.

• Flexible and re-sealable
• Compatible with most Australian roof profiles
• Quick-install designs reduce labour time

Considerations When Selecting Dektite & Silicone Products

Making the right product selection is crucial for the longevity and performance of your installation.

1. Roof Type and Surface

Choose a dektite flashing compatible with your roofing profile (corrugated, Klip-Lok, tile, etc.). Some flashings are specifically shaped to accommodate raised or ribbed profiles for better sealing.

2. Penetration Size and Material

Select the correct size flashing for your conduit, pipe, or bracket. Most flashings support a range of diameters with marked trimming guides. For high-temperature applications, opt for silicone over standard rubber.

3. Temperature and UV Exposure

For rooftops exposed to intense sun or heat—common in Australia’s northern regions—use silicone roof flashing, which resists cracking or fading over time better than EPDM.

4. Sealant Compatibility

Ensure your silicone sealant is compatible with roofing materials (metal, concrete, PVC). Neutral-cure silicone is recommended as it won’t corrode or degrade adjacent surfaces.

5. Compliance and Longevity

Always use products rated for long-term outdoor exposure and certified to roofing and electrical standards. This ensures both insurance compliance and safety during audits.

Frequently Asked Questions (FAQs)

1. What is the difference between Dektite and standard roof flashing?
   Dektite is a brand of flexible flashing specifically designed for roof penetrations. Unlike rigid metal flashings, it conforms to the roof surface and around pipes or conduit, creating a more effective waterproof seal.
2. Can I use general-purpose silicone for solar installations?
   No. Only silicone roof flashing products rated for outdoor use and compatible with electrical/metal surfaces should be used. These are formulated to withstand heat, UV, and long-term exposure.
3. How do I install Dektite flashing on a corrugated roof?
   Trim the cone to fit your pipe size, slide it over the pipe, press the base onto the roof profile, and apply silicone around the base before securing it with roofing screws or rivets.
4. Are Dektite products reusable if I relocate my system?
   In most cases, no. Flashings are designed for single-use installations. Removing and reusing them may compromise the seal and is not recommended.
5. What type of silicone sealant is best for use with Dektite?
   Use a neutral-cure, UV-stable silicone rated for roofing applications. Avoid acidic sealants, as they can corrode metals or degrade rubber components over time.
