Spray Polyurethane Foam

Don’t start from scratch! Elastomeric roofing can be sprayed right on top of your existing leaky roof.

Spray Polyurethane Foam (SPF) or elastomeric coating is a roofing and insulation material that has been used in the roofing industry for over 45 years with great success in stopping leaks. SPF is composed of billions of closed cells making it a seamless, insulating sheet when applied to an existing roof. A combination of isocyanate and polyol is fed through a proportioner, a device that introduces a flowing stream of water to produce foam solution.

Many roofs, through aging or poor craftsmanship, start to deteriorate and sag in places. The sagging causes puddles and pools of water to accumulate creating the perfect spot for leaks to start. With polyurethane foam, DMD can add additional layers to create a level roof, ensuring no more pooling. No other roofing option can do this! It saves capital by adding to what exists instead of replacing the substrate of a building. The lightweight properties ensure that no additional construction needs to take place before fixing your roof. DMD’s elastomeric roof coating can be bound to virtually any roofing surface: EPDM, BUR, Mod-Bit, Concrete, Metal, Wood and Composite Decking.


DMD uses only Conklin Spray Roofing Systems when restoring roofs. The Conklin SPF Roof System is the industry’s only 18-year non-prorated warranty that ensures years of leak-free roofing.

The benefits to using elastomeric roofing make Conklin’s product the best in the business:
