Henry Co HE208R004 Roof Cement Cartridge 11 Oz

Product Description

The HENRY CO HE208R004 is a rubberized wet patch roof cement packaged in an 11-ounce cartridge. It is formulated for patching and sealing roof surfaces in wet or dry conditions, making it suitable for emergency repairs where moisture cannot be fully cleared before application. The rubberized compound provides flexible adhesion to roofing materials, resisting cracking and shrinkage after cure. Roofing contractors and general contractors performing low-slope or flat roof maintenance are the primary installers of this product.

This cartridge-format cement is used for patching cracks, gaps, and small damaged areas on built-up roofing, modified bitumen, asphalt shingles, metal flashing, and similar roofing substrates. The cartridge format is compatible with standard caulk guns, allowing for controlled application in tight or elevated work areas. It is well suited to residential repair work and light commercial maintenance where a small-volume, ready-to-use patch material is preferred over bulk-can products.

Installation Notes

Application is performed by licensed roofing contractors or qualified general contractors. Load the cartridge into a standard caulk gun before use.

Follow all local building codes and manufacturer surface preparation guidelines to ensure proper adhesion and long-term performance.
