Sashco Clear Roof Sealant 1-Gallon — Ultra-Elastic, UV-Resistant Leak Repair

Sashco 14004 Clear Roof Sealant is a one-gallon, ultra-elastic roof repair caulk formulated to permanently stop and prevent leaks while remaining clear and flexible.

If you need a discreet, long-lasting seal for flashing, vents, gutters, skylights and other rooftop penetrations, this clear elastomeric sealant offers durable adhesion without the messy look of asphalt products. It stretches and flexes with temperature swings, resists UV and mildew, and can be used immediately on damp surfaces or in cold weather — making it practical for year-round roof maintenance and emergency repairs.

How does this sealant perform on different roofing materials?

This formula adheres to a wide variety of substrates including metal, fiberglass, shingles, wood, PVC and many other common roof surfaces. Its strong tack and elastomeric film maintain contact even as materials expand and contract, reducing gaps where water can intrude.

• Suitable for metal, composition shingles, TPO, EPDM, wood and more
• Stays flexible to follow thermal movement without splitting
• Clear finish avoids visible black or brown patches

Can I apply it in wet or cold conditions?

Yes — Sashco 14004 is formulated to bond to damp surfaces and tolerate immediate exposure to rain and snow after application. It also resists freezing so it can be used in colder months when urgent repairs are needed.

• Adheres to damp substrates; no need to wait for fully dry surfaces
• Won't freeze in storage or on-application temperature ranges
• Rain-safe shortly after tooling — ideal for emergency fixes

Will the sealant remain flexible and UV-stable over time?

The elastomeric chemistry prevents the product from drying hard and becoming brittle, and added UV resistance helps the clear finish resist yellowing and breakdown. In practical terms, it keeps sealing performance far longer than conventional asphalt-based mastics.

• Elastomeric — expands and contracts with seasons
• Resists UV degradation and stays clear longer
• Designed to outlast asphalt sealants by an estimated 2–3 times

How do I use it, and what are the package details?

Apply directly from the one-gallon container with a caulking gun or pourable applicator, tooling to a smooth bead for the best seal. Clean loose debris first; solvent cleaning is not usually required. The product is paintable if you need to match a roof color after curing.

• Package: 1 gallon; Part Number 14004; made in the United States
• Dimensions: 22.86 L x 25.4 H x 24.77 W centimeters; Weight: 8.7 pounds
• Tool, smooth, and allow to cure per manufacturer instructions; paintable when cured
