Roof Surface Fillers

Heavy Duty Roof Patching Compounds

These patching compounds are the most flexible and watertight we offer.

Roof Patching Compounds

Repair holes and seal gaps in roofing and gutters. These patching compounds are durable and water resistant.

Roof Crack Fillers

Fill cracks with these coatings to stop leaks and deaden sound.

Temporary Roof Leak Patching Compounds

Make a temporary repair to cracks in any flat roof. These patching compounds are a powder that forms a thick gel in minutes when poured directly into standing water and rain.

Adhesive-Back Roof Repair Rolls

Roll out a fast fix for leaky roofs and gutters with these peel-and-stick rolls.

Roof Repair Mesh Fabric

Reinforce hot- and cold-applied asphalt patching compounds and coatings with this flexible fabric.

Roof Joint Sealants

All-Weather Application Roof Joint Sealants

Fix roof leaks in cold and wet conditions. These sealants can even be applied underwater.

Roof Joint Sealants

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Self-Leveling Roof Joint Sealants

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

Paint and Coatings

Reflective Acrylic Coatings for Roofs

Reflect at least 85% of the sun's rays to reduce cooling costs. These coatings also restore and reinforce your roof by filling cracks and forming a water-resistant seal.

Moisture-Resistant Reflective
Silicone Coatings for Roofs

Made from silicone, these coatings are more durable than acrylic coatings for roofs and have better resistance to pooling water. They reflect up to 90% of the sun's rays to reduce cooling costs.

Reflective Asphalt Coatings for Roofs

These coatings reflect up to 60% of the sun's rays. They also restore and reinforce your roof by forming a water-resistant seal.

Coatings for Roofs

Use these coatings to form a water-resistant layer to restore and reinforce your roof.

Brush Roof Applicators

Stiff natural fibers are secured to a wood block to apply thick roof coatings and patches.

Brush Floor Applicators

Apply concrete and asphalt sealants as well as floor coatings.

Paint for Roofs

Hide blemishes and protrusions on shingles and flashing. This paint matches common roofing material.

Fastening and Sealing Tape

Rubber Sealing Tape

Patch and seal roofs, window frames, gutters, and vents with this conformable tape.

Sealing Tape for Large Gaps and Voids

An alternative to caulk and rubber sealants, this tape comes compressed and gradually expands to fill large gaps and voids.

Aluminum Flashing Tape

Use this tape for a watertight bond on gutters, roofing membranes, and other building materials.

Foam Sealing Tape

Stop water penetration with this tacky, flexible tape. It conforms to irregular shapes and expands to fill gaps. Use it on freezers, windows, and in marine applications.

Heavy Duty Sealing Tape

This tough, abrasion-resistant tape sticks to itself, so you can layer it over joints and seams to create an extra-strong bond. The thick adhesive conforms to fasteners and gaps to keep water out, even in extreme conditions.

Reinforced HVAC Tape

Reinforced with fiberglass, this tape is flexible yet resists tearing. Use it for sealing and patching insulation and duct.

UL-Printed HVAC Tape

For easy identification, this tape is printed with flexible duct standard UL 181A-P or UL 181B-FX.

Foil HVAC Tape

Seal foil-jacketed insulation as well as air-conditioning and refrigeration systems with this conformable aluminum tape.
