Roof Repair Products


When dealing with a leaky commercial roof, finding the right product that can be applied quickly, is imperative to preventing long-term damage to your building and equipment. Waiting too long will most likely cost you more, as uncontrolled moisture can damage your roof to the point where a full and costly replacement is necessary.

What do you do when you have a leaking metal roof seam or problem with fasteners on your metal roof? Weather can wreak havoc on a metal roof. Thermal movement is created by changing temperatures, and as roof materials expand and contract metal roof seams can become loose. Bad weather can further the damage, and early intervention can save your metal roof.

Topps® Products has a solution. Seam/RivetGuard™—our popular product specifically designed for metal roofs—seals, caulks, and withstands normal thermal movement from changing temperatures and more. The specially compounded, synthetic rubbers elongate further when warm and needed most and become stronger in cold climates, keeping seams and fasteners sealed in all climates.

Strong and elastic, Seam/RivetGuard™ seals seams that are properly closed. The product locks seals properly tightened fasteners and protects against rust and future failure at critical points.

Seam/RivetGuard™ represents the ultimate gelled formula sealant for both seams and fasteners where a one-coat application does both. This makes it a real labor-saver.

For larger sectional areas, you can use this product together with Polyprene® cement, and Topps Seal® coatings.

  • Seals seams and fasteners
  • Leaves no voids

Can incorporate PolyCore™ polyester reinforcement fabric, where needed, for more critical areas

SeamGuard™ WB

SeamGuard™ WB expands the effectiveness of sealing seams and fasteners with water-based coating systems by adding 750% elongation and an enhanced adhesion package. The greater elongation and enhanced performance helps stop leaks and prevent future capillary action which can result in problems later.

SeamGuard WB, which applies by airless sprayer or roofing brush, saves costly labor of being on hands and knees as associated with tapes more typically required with water-based coatings. SeamGuard WB can plug up to 1/16" gaps that you might not otherwise see. This liquid sealant applies in two coats after all seams and fasteners are tightened flush during roof preparation.

This seam sealer provides a labor-saving spray- or brush-on liquid sealer.

  • Seam and fastener sealer for use on Topps Seal® WB (water-based) applications
  • Applies in two coats to develop into an effective membrane-like seal that prevents wicking moisture
  • Accepts PolyCore™ fabric for making repairs and adding reinforcement where extra strength is required

PolyCore™ stitch bonded 100% polyester reinforcing membrane makes every repair stronger. The precisely spaced warp in the material provides integrated channels for liquid rubber to flow through, interlocking and further increasing dimensional integrity. PolyCore II™, with its flatter profile, permits complete encapsulation with less coating.

This reinforcing fabric is the premier membrane for adding strength to critical roof areas and repairs.

  • Exceptional multi-directional strength
  • Superior elongation properties
  • Adds strength to critical roof areas where repairs are made

4" PolyCore™ is used for seams. 
6" PolyCore™ is used for flashing. 
40 - 42" rolls of PolyCore™ are used to efficiently cap larger sections, including entire roofs.

For Roof Rust Removal Using Solvent-Based Coating


The success of any coating applied to metal depends upon the effective surface preparation of any underlying corrosion. The chemistry of RustArrestor™ for use with solvent based systems make this possible using less labor than other rust removal methods.

RustArrestor™ is applied to metal roof surfaces prior to power washing. It penetrates and loosens light rust in just 10 minutes for removal with high pressure water. It also converts other rust to a more stable oxide making it ready for coating.

RustArrestor™ easily prepares rust and makes it ready for coating.

  • Dissolves light corrosion
  • Cleans the roof surface
  • Easy to use, may be brushed or sprayed on
  • Leaves no film
  • Pre-mixed and ready to use

Masonry and Concrete Primer


This penetrating, clear, thin primer is used to prepare porous, non-painted masonry and concrete for sealing with Topps Seal® and other coatings. ClearSeal™ absorbs and bonds light surface oxidation and forms an initial seal beneath the surface. Prepares oxidized or chalked surfaces so they may be coated over with excellent adhesion by a sealant like Topps Seal. ClearSeal™ applies at approximately one gallon per 100 – 150 sq. feet. The coverage will depend on usage.

  • Primes uncoated masonry/concrete
  • Absorbs and binds slight chalkiness
  • Temporary water repellency
