White Lightning's All Purpose Adhesive Caulk is ideal for applying Zinc Roof Defense to asphalt roof shingles. It has excellent adhesion qualities to bond the zinc flashing with the shingle. It’s the only roof sealant that can be applied to a wet or moist surface and it can withstand extreme temperatures both high and low.
All purpose adhesive caulk also is great for waterproofing; a small dab on top of the nail heads will assure that no water will enter.
Purchase one tube of adhesive caulk for every 50’ roll of Zinc Roof Defense that you buy.
