Expandothane is produced by DOW Chemical

At Superior Seamless Roofing our two layer polyurea and silicone roofing system is the most advanced coating technology of seamless roofing systems on the market today. Our base coat membrane is Expandothane. It is manufactured by DOW Chemical and contains micro blowing agents that create a tough and flexible waterproofing membrane capable of expanding by five to seven times it’s volume volume and cures in less the a minute. With this amazing ability for expansion, Expandothane can seal cracks, seams, crevices, and offers complete waterproofing capabilities. Our product will make your roof watertight almost immediately. Expandothane is the only product on the market that can offer these advantages and comes with a FULL LIFETIME WARRANTY.


Superior Seamless Roofing is a full service roofing contractor for commercial and industrial roofing.  We assist owners, building operators, property managers and government employees with waterproofing, silicone roof coatings and roof replacement. Our Seamless Roofing System utilizes the most advanced coating technology of seamless roofing systems available called Expandothane. Our Seamless roofs are comprised of a two layer membrane system.  The base membrane is our ExpandoThane™ product that is an expanding waterproofing compound. It expands 5 to 7 times its liquid state and solidifies in less than one minute,almost immediately waterproofing your roof.  It is comprised of modified polyurea with micro blowing agents that create a durable and pliable waterproofing membrane that seals gaps and crevices. This cutting edge product creates a roof covering that completely eliminates water from seeping into your building.

The secondary membrane is a Silicone Roof Coating.  Silicone  is a high solid non VOC liquid silicone that primarily functions as a U.V. light blocker for the ExpandoThane membrane. It also produces a secondary layer of waterproofing to the seamless roofing system.  Some of the other benefits of the silicone layer is its high reflectivity. This feature alone has seen building efficiency improvements of 10 to 15 percent to the interior of the building because the coating is insulates the weather from outside as well.

The average cost of our Superior Seamless Roofing System is as much as half the cost of a traditional roof system and is covered by a manufacturer’s 15 year material and labor warranty.

We Have a Much Better Roofing Solution!


Your roofing system is the most important aspect of your commercial building. It protects 100% of your assets. It also accounts for a majority of your monthly business expenses due to the heat load it creates on the building. Did you know that traditional roofing systems account for more than 50% of the energy loss on your building? Consider the expense to continuously make repairs year to year on your aging roof system and the rising cost of energy each year and it just makes sense that there is a better solution to these problems other than replacing your entire roof! We specialize in a state-of-the-art, highly efficient roofing system that can either replace or refurbish any existing commercial roofing system at nearly 50% less cost!

Our Expandothane roof coatings are applied directly to your existing roofing system; you simply apply a layer of Expandothane on top of the roof. You can still utilize your current roof surface, roof deck, and insulation with a silicone roof coating.

There is no need to tear-off your existing roof when you install Expandothane roof coating. At the end of the silicone’s warranty period, you can apply another thin layer of coating to renew the warranty. This means you will never again have to deal with the expense and negative environmental impact of roof removal.

Our company takes pride in being able to provide cost-saving roof coatings and flat roof restoration for all commercial roofing applications. We are here to ensure the longest life possible for your roofing asset and one of the ways we do this by installing our customer’s roofs with our roof coating system.

What is a roof coating?

Roof coatings are liquid compounds, created by Dow Chemical, that are either sprayed directly onto your existing roof. When correctly applied, they create a seamless, water-tight membrane.

How can a roof coating help?

There are many ways you and your building can directly benefit from installing a roof coating system.

One of the main benefits is that they are ENERGY STAR ® certified and can help in lowering your annual heating and cooling costs. While they save you money in utility costs, they are almost completely maintenance free.

Can my roof be coated?

Roof coatings are a very popular choice for building owners and property managers because they can be applied to various roofing applications. Examples include; metal roofing, single-ply spray foam, rubber, flat modified bitumen, concrete among other common roofing materials.

How is my roof surface prepared for a coating?

A roof needs to be thoroughly cleaned and completely dry before it can be spray. Our technicians will take the time to ensure your roof properly prepared before it is sprayed.

How long do roof coatings last?

When applied correctly by a professional, a coating can last a lifetime. You will have to replace the top silicone membrane after 30 years.

Can my roof be coated?

The most destructive weather to concrete, masonry and natural stone structures is water. The only way to prevent water damage is to protect your building by waterproofing it using water resistant products or materials. It may sound simple but it’s not.

It goes without saying that if you maintain your roof, it will help save you money and provide a safe and healthy environment for your business and workers.  If you examine your flat roof, and figure that it does indeed need repair or is leaking, then be careful about picking the company that you want to do the work.

The best waterproof roofing company CT to work with is one that uses modern technology and which has a great track and customer service record, and in addition can provide their clients with specifications and quotes.


Generally, the roof’s main function is to keep water out of your office building! Any roof not performing this function is not worth it.  A few professional companies have a special division for waterproofing, because this is so vital.

Our waterproof roofing company uses ExpandoThane. ExpandoThane is a tough expanding spray made of polyurea material which has been able to shield and protect roofings from harsh environmental conditions.  Also, it has among other things sheer strength, hardness and is thermal resistant.

ExpandoThane offers impactful resistance when it comes to roofing, polyurea coating and waterproof coating. With it, you are certain to repair any leaks, worn out and loose areas that are causing your building problems. It is durable and flexible. It creates a uniformed membrane which reduces the gaps on a rough terrain, closes around openings and any form of surface obstruction.

As a result of its durability, resistance and elastic toughness, it is used in demanding environments like industrial and commercial roofing, industrial structural surfaces, undercoating/sound protection, waterproofing and underwater containment, and so on.  Also, it is found useful within military, aerospace and marine industries.

The two sectors where ExpandoThane is used is the roofing industry and the waterproofing industry. One of its formulations of ExpandoThane is polyurea which is quite dependent on a roof for any form of adhesion.

Superior Seamless Roofing is a leading name of commercial and retail waterproof roofing and polyurea coating in CT, DE, RI, NJ, NH, VT and waterproof roof MA. With over 20 years experience and a computerized estimating department, Seamless Waterproofing is a name you can trust when you want the very best for all your waterproofing needs.
