Frequently Asked Questions
Which sealant suits a roof joint?
Match the sealant to the joint's movement, width, and materials. N40 and N70 silicones are named for metal roofing and weather sealing. Bostik and Sika polyurethanes suit high-movement construction joints. Check the product data for the metals and exposure involved.
What seals a leaking roof penetration?
For pipes, screws, and seams, a flexible weather-proof sealant does the job when the substrate is clean. Seal around the penetration, tool the bead, and let it cure before it rains. For big damage, repair the membrane first.
Why put foam in a joint before sealant?
Backing foam sets the sealant depth and stops it sticking to the back of the joint. That lets the sealant stretch as the joint moves. Biyseal impregnated foams also close gaps in cladding and valleys. Size the foam to the joint width.
Can I use any silicone on a roof?
No. Roof joints move and take full weather. Use a silicone or polyurethane that names external exposure and the metals in your roof, such as Colorbond or zinc. Neutral-cure products suit coated metals. Check compatibility in the data sheet.
Do I need a sausage gun?
Yes, when the sealant comes in sausage packs. The M8504 cordless gun pushes viscous polyurethane and hybrid sealants at a steady, even rate without a hose. Match the gun's thrust and nozzle to the pack format you are using.
How do I seal between roof sheets and flashing?
Clean and dry the metals first. Set backing foam where the gap is deep, then run a weather-rated sealant bead and tool it smooth. Follow the sealant's cure time before closing the roof up. For movement joints, use the width the product data specifies.
