EnergyGauge Tech Support
Throughout the years we've been using the "composition shingles" for setting with "flat" configuration for contemporary flat roofs with built-up or membrane roofing. This decision was based on an engineering consultant recommendation. Basically, he said, "this is what we do based on inquiring with EnergyGauge." So we have always done it the same way. We've tried looking for anything written to assert this, but it is non-existent. Could we get a dedicated option under "roofing material" that addresses this? As in "membrane" or similar. Thanks.
