Pro Performance. Delivered.

Where HP4 Fits

Roofline Details Demand More From a Sealant

Roofing and flashing joints are exposed to constant expansion and contraction, direct weather, temperature changes, and transitions between metal, masonry, wood, PVC, composites, and other materials. The sealant at these details has to stay flexible while maintaining adhesion and a finished appearance.

HP4 is a high-movement hybrid polymer exterior sealant designed for exactly that kind of work.

Flashing Transitions

Seal metal flashing transitions and exterior joints where different materials meet.

Gutters & Roofline Details

Use at gutter transitions and roofline details that need flexible exterior sealing.

Fascia & Soffits

Create clean, durable joints at fascia, soffit, trim, and adjacent exterior materials.

High-Movement Exterior Joints

Handle joints that expand, contract, or move with changing temperatures and building conditions.

Why HP4 Works for Roofing & Flashing Details

ASTM C920 Class 50 Performance

Designed for high-movement joints where flexibility matters.

Damp or Slightly Wet Surfaces

Remove standing water when jobsite conditions are less than perfect.

Paintable in as Little as 1 Hour

Useful where the finished detail needs to coordinate with differing materials.

Broad Substrate Compatibility

Suitable for porous and non-porous surfaces.

Fast Skin Time

Helps reduce dirt pickup and supports a cleaner finished bead.

V-Notch Nozzle Included

Supports consistent bead shape and controlled application.

Roofline Project Details

One Exterior Sealant Across the Roofline.

Contractors rarely encounter just one material at a roofline. Flashing may meet siding. Gutters meet fascia. Coated metal meets masonry, trim, PVC, or composite components. HP4 is designed to simplify those transitions by giving crews one professional exterior sealant with the adhesion and movement capability to handle a wide range of common building materials.

Common Substrates

Aluminum, galvanized steel, and coated metals.

Masonry, brick, stone, and concrete

Fiber cement, engineered wood, and wood trim.

PVC, vinyl, and composites.

Other porous and non-porous construction surfaces where compatibility has been confirmed.

Application Guidance

1. Clean the joint and remove loose material, dirt, oil, and standing water.

2. Confirm compatibility with the specific roofing membrane, coating, metal finish, or manufacturer system before application.

3. Apply a continuous, properly sized bead to the joint or transition.

4. Tool the bead as needed for full contact and a clean finished profile.

5. Where painting is required, allow appropriate cure/skin time and test paint compatibility first.

Technical Note: Roofing systems, membranes, coatings, and factory finishes can have product-specific compatibility or warranty requirements. Confirm suitability with the applicable manufacturer documentation before installation.
