What should be avoided when selecting a roofing material to prevent structural issues?

When selecting roofing materials, it is essential to consider their weight because an increase in weight can lead to significant structural issues. Buildings are designed with specific load-bearing capacities, and heavier roofing materials can exceed these limits. This can result in stress on the supporting structures, ultimately leading to sagging, structural failure, and potentially severe damage to the home. Additionally, upgrading to heavier materials without appropriately reinforcing the roof's support structure can compromise the overall integrity of the building.

Other options, such as color change, style difference, and material mismatch, do not typically pose the same immediate risk to structural integrity. While they may affect aesthetics or compatibility with the existing architecture, they do not directly influence the load-bearing capacity of the roof, making weight increase the most critical factor when it comes to avoiding structural issues.
