Roofroll Stix is designed for roofing contractors and DIY homeowners who need a durable, reliable solution for sealing chimneys, dormers, and roof junctions without the labor intensity of traditional lead. Its primary benefit is the high-performance, full-width butyl adhesive backing that allows for rapid, secure installation on various surfaces. A key caveat to consider is that while it is flexible and easy to mold, installers must ensure the substrate is perfectly clean and dry to achieve the maximum long-term bond strength required for its 40-year service life.

Yes, the EPDM surface can be painted with standard external-grade flexible masonry or metal paints to match your roof color scheme.
No, the butyl adhesive is pressure-sensitive and is designed to adhere at room temperature without the use of heat guns or torches.
Yes, it is a non-toxic, lead-free alternative, making it safer for rainwater collection systems compared to traditional lead.
It is designed to remain stable and maintain its adhesive properties through extreme thermal cycles common in outdoor roofing environments.
It is best installed when the surface temperature is above 5 degrees Celsius. In very cold conditions, warming the adhesive side slightly with a hairdryer can improve initial tack.
Ensure the substrate is completely clean, dry, and free of dust. If applying to porous surfaces, consider using a high-quality surface primer.
Use a seam roller to press firmly from the center of the strip outward to the edges to ensure complete contact and push air out.
Check that the surface was dry. If the edge is loose, clean underneath with an appropriate solvent (if material allows), let dry, and re-press firmly.
Installation is straightforward but requires attention to preparation. First, ensure the surface is free of dust, loose debris, oils, and moisture; the butyl adhesive relies on a clean substrate for maximum longevity. Using a primer on porous masonry is recommended to ensure a secure bond. When applying, use a rubber roller to apply firm pressure from the center outwards to eliminate trapped air bubbles. The material is compatible with most standard roofing materials including clay tiles, concrete, slate, and brick. For care, keep the material away from solvent-based cleaners which could degrade the adhesive bond. Periodic visual inspections every few years are recommended to check for mechanical damage or potential debonding caused by extreme structural shifting.
