Description
Soudal Roof & Gutter Silicone Sealant is a highly UV-resistant, neutral-cure silicone that creates a fully elastic, permanent-colour joint for exposed roofline work. It is easy to apply and built to hold up where joints sit in full sun and weather year-round.
Roof & Gutter Silicone Sealant suits roofing, flashing, skylights and guttering in building construction, along with construction joints, sealing between treated wood and glass, and other general sealing jobs. Explore our full silicone sealant range to find the right solution for your next sealing, weatherproofing or construction project.
Why Choose Soudal Roof & Gutter Silicone Sealant?
Roofing joints take the harshest exposure on a building, so the sealant has to survive sun, water and constant movement.
Made for sun exposure. Its high UV resistance holds up on roofs and gutters where joints face full sun, rather than chalking or breaking down within a season.
Moves with the roof. A fully elastic cure lets the joint flex with the daily expansion and contraction of roofing and flashing without splitting.
Sheds water and resists mould. It is highly durable, mould-proof and corrosion-free, which matters on joints that stay wet through guttering and rain.
Skins fast. Quick skin formation lowers the risk of a fresh joint being spoiled by rain before it sets.
Features and Benefits
- Great UV resistance: Built for full sun on roofs and gutters, so joints hold up outdoors over the long term.
- Stays elastic after curing: Flexes with roof movement and thermal expansion without cracking.
- Highly durable: Stands up to weather, water and temperature swings on exposed joints.
- Fast skin formation: Skins over quickly to reduce the chance of rain spoiling a fresh joint.
- Permanent colour: Holds its colour rather than fading or yellowing in the sun.
- Very good adhesion on many materials: Grips roofing materials, flashing, treated wood and glass.
- Impervious to mould: Resists mould growth on damp guttering and roofline joints.
- Corrosion free: Safe against metal flashing and fixings in the seal.
- Very easy application: Tools out smoothly for a clean, weathertight finish.

FAQs
What is Roof & Gutter Silicone Sealant used for?
It seals roofing, flashing, skylights and guttering in building construction. It also handles construction joints, sealing between treated wood and glass, and other general outdoor sealing jobs.
Is Roof & Gutter Silicone Sealant UV resistant?
Yes, it is highly UV-resistant and made for joints that sit in full sun on roofs and gutters. That helps it hold up outdoors without chalking or breaking down like less weather-rated sealants.
Can it be used on skylights and flashing?
Yes, it suits skylights, flashing and guttering, with very good adhesion across common roofing materials, treated wood and glass. It stays watertight on the exposed joints these areas rely on.
Will it stay flexible as the roof moves?
Yes, it cures to a fully elastic joint that flexes with the daily expansion and contraction of roofing and flashing. That movement tolerance is what keeps the seal intact through temperature swings.
