The inspection was carried out on a house undergoing a roofing material change from shingles to tiles, which typically adds more weight to the structure. Due to this increase in weight, it was crucial to assess the structural integrity of the building to ensure it could support the new roofing material.

During the inspection, engineers focused on evaluating both the gravity and lateral systems of the building. The gravity system includes elements that support vertical loads, such as beams, columns, and the roof itself, while the lateral system involves components that resist horizontal forces like wind or seismic activity.

To accommodate the additional weight of the roof tiles, the engineers strengthened the supporting members. This involved reinforcing existing beams and columns, adding new ones, and ensuring the connections between these components were robust. The goal was to confirm that the building could safely handle the increased load without compromising stability or safety.

The inspection and subsequent reinforcements were essential to maintaining the structural integrity of the house, ensuring it remained safe for its occupants and complied with building codes and standards.
