EPS Insulation Prevents Your Roof from Becoming a Waterin’ Hole

Driving the rural highways of my territory, I often see a bulldozer or other equipment pushing dirt around in a large field. Always strategically placed in a low-lying area of the field, a berm is being created to catch the rainfall runoff from the surrounding area. To the rancher, this oasis will help sustain his herd. Strangely enough, a very similar thing can occur on a flat or low-slope roof. Unfortunately, on a roof this “ponding” will result in major problems.

I recently searched the Internet for leading causes of flat and low-slope roofing problems. The results were numerous and consistent. Most websites pertained to materials and workmanship. Only one design-related issue showed up regularly and it always listed near the top of my searches. Ponding water!

Standing or ponding water on a roof WILL find any hole or gap in the roofing membrane to create a leak. The standing water will also cause the membrane to degrade faster and put a substantial additional load on the roof structure itself. Whether new construction or the reroof of an existing structure, if proper care is not taken in roof design to move rainwater efficiently and quickly from the roof area, major damage can occur. The best way to accomplish that task is with tapered insulation. Foam-Control EPS Roof Insulation offers the versatility needed to design highly efficient drainage for your roof. Consisting of flat and tapered foam pieces, slopes, crickets and saddles can be provided to create positive drainage in as few as two layers of material and to thicknesses as great as 36”. That versatility offers substantial savings in both material and labor costs compared to the most common polyiso materials, which are available only in relatively thin sheets.

So the next time you inspect a roof for a building owner, notice if you happen to be standing in water, mud, a layer of dirt, or just a dark ring on the membrane. If so, be sure to design the new roof with Foam-Control EPS Roof Insulation. Figuratively speaking, you’ll be protecting his herd.

This insulation consists of flat and tapered foam pieces from which slopes, crickets, and saddles can be provided to create positive drainage in as few as two layers of material and to thicknesses as great as 36”.
