Before a new rooftop unit goes up, it's important to know the structure beneath it can handle the load.
Our team provides rooftop analysis to help building owners, engineers, and contractors evaluate whether existing roof systems can safely support new equipment such as HVAC units, air conditioning systems, communications equipment, and other rooftop installations.
By combining field inspections with structural analysis, we help identify potential concerns before installation begins; reducing risk, avoiding costly surprises, and supporting informed project decisions.
When it comes to rooftop additions, understanding the structure is the first step toward a successful installation.
