Welcome to Hydroseal

The average lifespan of a commercial building in the USA is 35-50 years, while the average lifespan of

today's roofing systems is 12-15 years.

Why, in this day and age, is the average acceptable?


It is not acceptable to Hydroseal. Hydroseal is not average.


The 'traditional' roofing industry would have us believe that sustainability is 'constructing, maintaining, and demolishing a roof system',only to construct another in it's place. They advise that this is 'preserving the global environment'.


Our team believes there is a better, more environmentally beneficial way to do things. Preserving the planet for future generations does not constitute the dumping of millions of tons of roofing debris into the country’s landfills every year.


An Hydroseal roofing system will be the only system that ever needs to be installed on your roof. This is true sustainability and is a legacy worthy of leaving behind for generations to come.

Through our web site we intend to begin the process of working with and presenting to you, the Contractor, the building owner, or even the Facilities Manager, that our range of products can, and will, eradicate the need for a capital expense budget to replace your roof every few years. We will show you a range of roofing and waterproofing systems that are environmentally friendly, that eliminate the need for tearing off, that provide cool roof energy savings benefits, and that, most importantly, will maintain your building's watertight integrity as long as it is standing.

Hydroseal recognizes that the Contractor is the key piece in all of the moving parts that comprise a successfully completed project. Thus, it is our goal to provide the products and the technical back-up that enables the Contractor to complete the job in good time, within budget, and with the confidence that he or she is not going to be called back time and again for unresolved issues.

Further, we are making it our mission to provide each and every Contractor with many other options to expand their own business, via Hydroseal led initiatives.


The reasoning is very straightforward: if the Contractor expands his business in conjunction with Hydroseal, we expand ours.


Simple and transparent.
