Topps Roofing Systems
Metal roofs seldom wear out. They’re lost from lack of maintenance. Temperature changes loosen components. Weather erodes the original, thin protective finish. The result is leaks and surface rust.
The Topps® complete, seamless restoration process for Metal Roofs seals, prevents leaks, corrosion and provides an ENERGY STAR€ bright white reflective surface which can drop peak energy cooling demand by up to 15%.
With proper care and a metal roof restoration and/or maintenance program, a metal roof can last for the life of the building. Controls leaks, rust, fasteners and flashings in a timely matter.

Acrylic Elastomerics vs. Solvent Base Elastomerics
Topps Seal® is a solvent base elastomeric. Topps Seal® WB is a waterborne elastomeric. When explaining differences between acrylic latex or water-based coatings and solvent-based coatings to a prospective customer, many of us have a tendency to get caught up in a competitive we vs. they sales approach. When formulated properly, both types of products can, and should, perform successfully when used in the right situations. If one type of coating were far superior to the other, we at Topps Products Inc. would not manufacture both. As one contractor once told me, you wouldn’t put chocolate syrup on a hot dog, any more than you would put catsup on ice cream. That doesn’t mean one product is inferior to the other.
Metal Market Needs – Elongation, Strength, Rust Prevention Topps® solvent-based rubber products were originally engineered and developed for the metal market. The two major problems associated with metal are rust and leaks. Both oxygen and moisture are needed in order for rust to occur. The low permeability (perm) rating in the solvent-based products will not allow moisture or oxygen to pass through the coating. The result? No more rust. The opposite is true with acrylics. Make the comparison by looking at the product specs side-by-side. Water moisture naturally triggers new rust development beneath the coating. Products with high permeability can take on moisture and are not as strong. Consequently, they require tapes at all seams. You will see this also by the product specs.
Constant expansion and contraction loosens fasteners. Acrylics are not capable of making the seal that solvent elastomerics make. Building owners have tried for years to stop these problems using asphalt, aluminum and acrylic coatings. These products are all limited in their physical properties. They always require tapes to get strength. Problems often recur after a short time. Topps Seal has the tensile strength, elongation, and moisture-blocking capabilities needed to correct the problems. This makes the Topps Seal solvent system the preferred product for metal roofs. Topps Seal liquid rubber, blended in a mild mineral spirits solution, far exceeds the physical properties of any water-based coatings — even our own Topps Seal® WB. Our solvent-based rubber has a minimum of 1000% elongation and 1,750 p.s.i tensile strength, is VOC/VOS compliant, and has tenacious adhesion characteristics over metal, concrete, BUR and many other substrates.
Waterborne for Breathable (Porous)Surfaces Water-based products breathe. Should moisture get into a porous (non-metal) substrate, or be in the substrate when the coating is applied, the water-based product would allow the vapor to exit much better than the solvent-based would.
Choose What is Best For Your Roof — Not Just What Someone is Selling.
Coating selection is the most important factor when selling and applying coatings. For metal, the stronger solvent system that cannot rust is clearly the superior choice. Acrylics may stick to metal, but do not offer all the benefits best for metal. Acrylics are best for surfaces that “breathe”. Topps offers a complete line of both solvent-based and water-based maintenance products. Competitors selling only one product, naturally present that for everything. However, better choices exist. Educate your clients; they cannot be expected to know this as well as you. The product specification sheets, in terms of comparing permeability (perms), strength, and elongation, help anyone come to the right conclusion.
We've Got Answers
Elastomeric coatings are elastic in nature, meaning they are more apt to move as needed.
Yes. Some have greater physical features than others. Some retain those features longer. These factors provide a good predictive, comparative value of one product relative to another.
ASTM and all other national and international tests require various physical feature minimums such as tensile strength, moisture absorption, moisture transmission rates… ability to cool a roof and more. Tests even report how items such as temperature will affect the most critical items such as elongation and strength, or how aging affects this. Some companies won’t reveal these if not in their favor. Therefore, it is wise to compare all features and be suspicious if they’re not printed in company literature when considering competing products.
No. That’s why ASTM, Miami/Dade County, and all others include multiple physical properties in their standards for roof coating products. Unfortunately, no one can accurately predict which will be more needed than another for any situation. “Minimums” don’t always handle it, making any work with those, risky business. This explains why our coatings such as Topps Seal® far exceed every national or international performance standard for elastomeric protective roof coatings. This does not mean they will perform miracles. However, they will outperform in situations where others with lower standards will fail.
It is important that basic properties such as Elongation and Tensile strength are evaluated AFTER aging. This advanced testing is required to pass the most stringent regulations such as the Miami/Dade County modified ASTM. Many products don’t report these if results are unfavorable. This is valuable because those features are most crucial with respect to weathering protection and often among the quickest to fail. Products which diminish the quickest are not simply weaker and less able to perform compared to others. They are very likely to provide even less protection later.
Most often this is contractor preference for clean-up by using just soapy water instead of the proper solvent (our solvent based products only involve ordinary simple mineral spirits found in most any hardware or paint store). California requires only water based products so we provide those for this market as well. Under special circumstances, such as application over fibered aluminum roof coating we will recommend only the use of water base. All our products are well within national VOC limits and therefore are widely used.
Yes. With each of our products, we utilize chemistry which modifies very slowly during weathering including UV exposure. Because our products are used in such varied climates from Middle East deserts, application on the Antarctic, the tropics of Asia and Africa…to every imaginable climate in between… we know we must be able to withstand greater conditions and provide a realistic and cost effective option where ever product is used. Consequently, even the acrylic basis of our TS Commercial WB is selected from among the thousands available, specifically for rooftop weathering, even when cheaper acrylic resins are available.
Consider this only if purchasing a product for reducing rooftop temperatures, and the transfer of that heat energy into the building, are valuable to you. All products that are Energy Star® or CRRC listed will show their reported change in value after 3 years, indicating how they perform over time. As all products are expected to change over time, reduced performance standards have been established. It should be noted that our flagship Topps Seal® even after rooftop aging, continues to exceed the minimum laboratory requirements expected only for roof coatings prior to exposure. This performance level is 50% greater than competitive products are required to meet after aging.
Joints provide potential for leaks. Our chemistry allows us to provide sealants in liquid form for more efficient application of those seals. This enables an additional level of sealing which is often ignored for cost reasons (bids) when it requires workers on hands-and-knees to otherwise install a seal. We provide a mesh for optional use where greater reinforcement is needed.
Yes. This comes back to our basic chemistry. It is anchored in synthetic materials that are not easily attacked by nature’s elements. To accomplish this, we started with the development of our repair compounds and built out. Polyprene® flashing cement was engineered some 40 years ago. From there we built our coatings. This is contrary as most will first come up with a coating to sell, then add sealants and repair compounds to make the coating work better. Consequently, it can be said that our flagship coatings are developed off our repair compounds. This makes them standouts and second to none.
