subroofing

Subroofing refers to the process of installing a secondary or additional layer of roofing material on top of an existing roof. This practice is also known as supplemental roofing or secondary roofing. Subroofing can be beneficial in various situations, including when a homeowner wants to upgrade their roof's appearance or add extra protection against weathering.

There are several types of materials used for subroofing, including membranes, felts, and shingles. The choice of material depends on the existing roof's condition, climate, and local building codes. In many cases, subroofing involves installing a new roofing layer over the existing one, using a specialized adhesive or mechanical fasteners to secure it in place.

Subroofing can offer various benefits, including improved durability, increased wind resistance, and enhanced energy efficiency. It can also provide a new and distinct layer of protection against water damage, mold growth, and other forms of degradation. However, subroofing may not be a suitable solution for all roofs, particularly those with severe damage or structural issues.

Before implementing subroofing, homeowners should consult with a qualified roofing professional to determine the best course of action for their specific situation. This assessment will help identify any potential issues with the existing roof, as well as determine the required materials and installation methods for a successful subroofing project. With proper planning and execution, subroofing can be an effective way to extend the lifespan of a roof and protect the building's interior and exterior surfaces.
