Don’t replace it… Restore it! A better roof at 1/3 of the cost.
Topps is a leading manufacturer of a variety of elastomeric roof coatings that have distinguished themselves with their versatility, durability and quality. When a roof is no longer performing, whether due to rust or leaks,a client can often save a large amount of money by repairing it with an elastomer instead of paying for a replacement.
Different roof materials and climates require different elastomeric roof coatings, which is why Topps manufactures both solvent-base elastomerics and water-borne elastomerics. Eagle Rivet uses both types in roof repair and insulation, depending on the requirements of the project.
Elastomers are polymers that have rubbery, elastic properties. They are important in roofing because their elastic properties allow them to compensate for expansion and contraction of the substrate during the day/night cycle and the change of seasons. Elastomeric insulation is much better than hardening materials such as spackle for plugging leaks and holes.
Elastomerics have another important function, one that has come to the fore in these days of high energy costs. Most roofs on homes and commercial buildings built before the last few years are dark in color. This increases their heat absorption, with tar/gravel roofs being the worst offenders, and makes the building more difficult and costly to cool during summer months.
Given that over 90% of roofs in the United States are dark-colored, and a black roof can increase in temperature by over 100°F, this translates into an estimated 15% increase in energy required to air-condition a single-story home.
Many government guidelines have begun to address this issue, with the Federal government requiring drastic cuts in energy use Federal office buildings. Many states also have energy use requirements, and changing roof color is a simple and important way to improve energy use statistics.
Unlike paint, that will dry out and flake, elastomeric roof covering is a great way to retrofit a roof for relatively low cost.
The biggest problems for commercial metal roofing is its tendency to rust and develop leaks. Topps Seal solvent-based elastomerics are liquid rubber compounds blended in a solution of mineral spirits, offering a high degree of water resistance. The sealant is also oxygen-proof; water and oxygen being the two main catalysts for rusting, this adds quite a few years to the maintenance-free lifetime of a metal roof. Modern solvent-based roof coatings also don’t freeze in cold weather, allowing for both a longer working season, which gives the client more flexibility when scheduling the job, and retaining their effectiveness throughout the winter months once applied.Solvent-based Topps Seal liquid rubber has a minimum of 900% elongation and 1500 p.s.i. tensile strength, and adheres not only to metal, but also concrete and many other materials.
Topps Seal WB water-borne acrylic sealants are more permeable to air and water, and are not as strong as solvent-based ones. They are best suited for surfaces like stucco, concrete and masonry, if the goal is to allow the building interior to “breathe.” They don’t seal out moisture completely, but still offer a considerable amount of resistance to wind-driven rain.
