Latty Ohio Industrial Roof Project

This was an exciting project that presented unique challenges for our company. With Latty Ohio being 1600 miles away from Salt Lake City and in a rural area of Ohio, staging for this project required very careful planning. In addition, the roof is about 110 feet up in the air with only a small elevator allowing 2 men at a time as access to the roof. This location is also known for high winds and the roof had many types of penetrations that Carlisle, the roof membrane manufacturer, had no details for. We submitted drawings to Carlisle for their approval on details not published by them which where used by the inspector when the final inspection was done.  The building owner wanted a 30 year warranty on this roof for labor and materials, which was issued by Carlisle and hence necessitated an inspection by them.

 

 

 

 

 

 

 

Roofing System and Materials

In order to meet these challenges we visited the sight, took video footage and measurements of the project and carefully planned to materials and tools needed. We were able to use a pulley and a tractor to lift the materials onto the roof. The specifications on this roof included the following:

  • Install 7/16 inch wafer board with all needed 2x4 framing members in cluttered areas of roof as needed to facilitate the installation of a water tight roof. New built up areas not to interfere with the functioning of the grain bin. 
  • Extend all temperature probe access pipes up a minimum of six inches to allow for proper seal to new roof membrane. Install cap.
  • Remove metal no-access plates round electrical room to allow access for roof installation. Re-install once new roof is in place under and around electrical room. Pitch pockets installed on feet of electrical room.
  • Install metal plates over walk way where metal meets concrete. Metal plates to be secured and will provide a surface suitable for water tight termination of roof membrane.
  • A 135 mil fleeceback TPO roof membrane installed, fully adhered to concrete surface. Install glue beads 4 inches apart. On roof area round electrical room and pulley, install double amount of glue to hold membrane in place on side of prevailing winds.

Job Summary

Seams heat welded. All vent pipes and hand railings flashed with pre-manufactured jacks. Angle Iron and I beam penetrations flashed with pitch pockets and pour-able sealer. All remaining roof penetrations flashed with custom made flashing. New drip edge installed on bottom edge on roof eave by electrical wires and eroded concrete. Remainder of roof eaves secured with termination bar into front face of concrete and brought up and over roof eave to be secured onto fleece-back membrane on roof surface. Wall flashing installed where needed and secured with termination bar and water cut off sealant. Metal wall panels to be cut as needed to facilitate roof membrane installation.

We estimated at total of 8 weeks for this project. We completed this in 3.5 weeks and where really happy with the final result.
