Revised LTTR Values (R Value) for 2016

In January 2014 we sent a newsletter discussing newly posted  LTTR values (R-value) resulting from revised testing criteria. According to the National Roofing Contractors Association (NRCA) the R value of 1″ of polyisocyanurate insulation has dropped once again effective January 2016. Why the change? This is the result of applying the newest test methods to insulation boards of varying temperatures.  Apparently boards at colder temperatures provide higher R values than boards at warmer temperatures. NRCA has chosen to refer

Cold Weather Related Roof Damage Explanation

With the recent colder weather you are likely experiencing an increase in roof leaks.  We would like to offer a brief explanation for this recent uptick in roof issues. After a very mild winter we are now receiving extremely low temperatures, ice, and an increase in  precipitation.  These weather changes result in a more active freeze/thaw cycle.  Freezing and thawing results in the expansion and contraction of exposed roof components.  The colder the weather, the more potential for extreme contraction.  This continued and extreme movement can

The extreme weather conditions that we experience in the Midwest can be taxing on buildings. For more than 4 months out of the year severe thunderstorms, heavy rains, and hot and humid temperatures are the norm. At the opposite end of the spectrum we experience high accumulations of snow and severely cold temperatures in the winter. This combination of extreme conditions can reveal a buildings true vulnerability to water intrusion and air leakage. Correcting these vulnerabilities

Winter if fast approaching those of us that live in the Midwest.  With the changing weather comes new seasonal issues for the construction industry.  Specifically, exterior components such as waterproofing of building walls and roofs.  Colder weather changes how construction materials react, perform, and how they should be installed.  These seasonal effects in addition to recent code changes, are resulting in a stronger focus for monitoring the installation of waterproofing components.  As a result we are seeing an increase in firms performing quality assurance inspections during the installation

Rooftop Solar Installation:

Rooftop solar installations and vegetative roofs are becoming popular with commercial and industrial building owners. These options have gained popularity because they can benefit the facility, tenant, or owner. A few of these benefits include minimizing energy costs, increasing marketability, and adding usable space. Developing a project with this many intricacies requires detailed review of the structure and all associated components.   Often the design of one of these systems is the product of a
