Membrane Systems

 

The weak link in “Membrane” systems, or any system of similar nature, are its seams, penetrations and flashings. If water can penetrate the envelope of the roof, saturation of the underlayment and/or insulation occurs. Damage occurs. The corollary is that the mass of the underlayment/insulation increases.

During a warm day, the roof warms. The unaffected areas of the roof warm at a “normal” rate. The water affected areas warm, at a slower rate, due to the increase in mass associated with the saturation. Eventually, the areas may reach equilibrium. Once the sun sets, the unaffected portion of the roof releases its absorbed energy at a “normal” rate. However, the affected portion of the roof, with the higher mass, will take longer to release its absorbed energy. There will be a differential in radiant temperature that is identifiable and quantifiable. If this differential exists, you know where to focus your investigative efforts for further testing.

A few things to consider in thinking about surveying a membrane roof for water damage: First, what are the tools to be used. Second, how are the tools to be used.
