Rough-Ride for Roof Mounted Equipment

Field reports from HVAC and roofing contractors indicate an increasing issue relating to the stability of rooftop equipment installations.  Earthquakes at 6.4 magnitude in January ran through the Caribbean wreaking havoc with the electrical grid and power lines, not to mention rooftop-mounted equipment.  Elsewhere, high winds and violent storms have caused the same.  As the [...]
