Engineered Rooftop Supports vs Field Built Wood Blocking
Engineered non-penetrating rooftop support blocks provide an alternative based on defined load capacity, support geometry, and membrane contact. Instead of relying on field-cut lumber, these systems are selected according to the supported load, required elevation, roof membrane, and available footprint. For building owners, contractors, and engineers, the comparison extends beyond initial material cost. Durability, load distribution, membrane protection, warranty requirements, installation methods, and available engineering documentation all affect whether a rooftop support system is appropriate for a project.
