Older multifamily buildings often struggle with uneven drainage, seam fatigue, and recurring leak points. Spray polyurethane foam (SPF) offers a different approach. Instead of installing sheets or panels, the system is applied as a liquid that expands and cures into a seamless, fully adhered surface.
As a multifamily spray foam roofing contractor, our team at Jaco applies foam in controlled lifts to create a continuous insulated layer that bonds directly to the existing substrate. This eliminates seams, a common failure point in traditional flat-roof systems.
Correcting Drainage and Ponding Water
Ponding water is one of the most common causes of premature roof deterioration in Covington. SPF allows us to contour the roof surface during application. By building a slope into low areas, we can redirect water toward drains without a complete structural rebuild.
After the foam cures, a protective coating is applied to shield the surface from UV exposure. That coating layer is renewable, extending the life of the foam core.
Insulation and Energy Performance
Spray foam provides both waterproofing and insulation in a single system. With high R-values per inch, SPF reduces heat transfer through the roof assembly. For multifamily properties, this can improve interior comfort and support lower energy demand during Georgia’s extended cooling season.
Because the foam adheres directly to the deck, it also helps reduce air infiltration, limiting moisture migration into the building envelope.
Installation Over Existing Systems
In many cases, SPF can be applied over an existing roof without a complete tear-off, provided the substrate remains structurally sound and dry. This minimizes debris, shortens installation timelines, and reduces disruption for residents.
If your multifamily property in Covington is experiencing drainage problems or recurring flat-roof leaks, our team at Jaco can evaluate whether spray foam is a practical restoration strategy for you. To get started, contact us to schedule a roofing assessment today!
