Age. Leaks. UV deterioration. Hail and storm damage. Your commercial roof isn’t immune to damage and it doesn’t last forever. But, you do have an economical and superior alternative to reroofing your commercial building. Spray Foam. Learn more below.
Spray foam has become increasingly popular in the past few years with builders across Texas as a preferred insulation method. The spray polyurethane foam is also used as a roofing material, but not many people are aware of this.
For more than a quarter of a century, spray foam roofing has mostly been used to reroof existing flat roofs on commercial and residential buildings. Single ply. Modified bitumen. Any type.
Norris Spray Foam sprays foam roofing in Texas for both residential and commercial projects. Commercial buildings with flat or low-slope roofs are common in our area, and many of them have old, leaky built-up roofing, so re-roofing commercial buildings is a significant portion of our business.
When you reroof with spray foam, you can:
- Save up to 50% of the cost of a tear-off and conventional reroof installation
- Permanently seal leaks that have increased in number over time
- Reduce energy costs as spray foam provides superior insulating properties which TPO and EPDM roofing don’t have
- Minimize weight load on your roof compared with other reroofing options
- Extend the life of your existing roof 20-30 years
Read on to discover more about why spray foam may be the best roof foam reroofing choice for your building.

A roof is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope.
The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials and the local traditions of construction and wider concepts of architectural design and practice and may also be governed by local or national legislation. In most countries a roof protects primarily against rain. A veranda may be roofed with material that protects against sunlight but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light.
A roof may also provide additional living space, for example a roof garden.
A flat roof is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof. Flat roofs, or “low-slope” roofs, are also commonly found on commercial buildings throughout the world. The National Roofing Contractors Association defines a low-slope roof as having a slope of 3-in-12 or less. Flat roofs exist all over the world and each area has its own tradition or preference for materials used. In warmer climates, where there is less rainfall and freezing is unlikely to occur, many flat roofs are simply built of masonry or concrete and this is good at keeping out the heat of the sun and cheap and easy to build where timber is not readily available. In areas where the roof could become saturated by rain and leak, or where water soaked into the brickwork could freeze to ice and thus lead to ‘blowing’ (breaking up of the mortar/brickwork/concrete by the expansion of ice as it forms) these roofs are not suitable. Flat roofs are characteristic of the Egyptian, Persian, and Arabian styles of architecture.
Spray foam is a chemical product created by two materials, isocyanate and polyol resin, which react when mixed with each other and expand up to 30-60 times its liquid volume after it is sprayed in place. This expansion makes it useful as a specialty packing material which forms to the shape of the product being packaged and produces a high thermal insulating value with virtually no air infiltration.
When selecting a roof coating for your single ply roofing, remember that protective coatings are only as good as their maintenance. To ensure that this seamless system continues to operate at peak performance, a yearly roof inspections is helpful in discovering hail damage or wind damage to ensure that your roof insurance stays in force.
