Premium polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO) membrane systems that offer outstanding reflectivity and are resistant to a broad range of chemicals, helping to extend the life of the commercial roof. During installation, single-ply membrane rolls are overlapped and heat welded together along with mechanically-fastening or fully-adhering with adhesive to form an exceptionally durable, waterproof, and energy-efficient shield that will deliver unsurpassed building protection for years to come.

Look forward to years of trouble-free protection, low maintenance
Conklin’s single-ply membrane roofing systems provide leakfree protection and exceptional energy savings for years. They maintain maximum reflectivity and energy savings, because their surfaces are resistant to dirt and discoloration. Annual cleaning is all that’s needed to keep them white.

Dramatically reduce cooling costs

Flat Roof “ponding water” Project

These building owners had no idea of the massive amounts of water collecting on their roof. They knew they had leaks but needed a professional to assess their roof. This liability called “roof ponding” can weight several tons and cause massive damage. After showing them the pics and calculating the excessive weight on their flat roof they decided to protect their investment with a new tapered PVC membrane roof. We brought them up to code and gave them peace of mind.

Tons of water on top of roof could not drain due to ponding. Ponding water is no longer acceptable in the industry or by the International Code Council. Ponding water can have a negative effect on any of today’s roofing systems and should be avoided at all times.

Over the years, many questions have been asked concerning ponding water and what type of long-term effect this water has on a roof. One of the biggest concerns can be weight; ponding water weighs approximately 5 lbs. per inch, per each square foot of roof surface. For example, a 20’x20′ ponding area at 1″ deep would equal 400 total square feet at 5 lbs. per foot, or a roof live weight of 2,000 pounds! That can be an additional ONE TON of live roof load adding stress to your building’s roof!

The above roof had more than 75’x35′ at 2-3″ deep in some areas. You do the math….
