The Roof: Critical Building Component
Historic preservation experts define the roof as the most critical building component for the preservation of historic buildings and advise that restoration measures should begin with the roof. Interior water infiltration from a failed or leaking roof can quickly destroy the prized historical building materials and ultimately destroy the entire structure.
Original Historic Roofs
For original roofs of sustainable materials such as slate roofing, clay tile roofing and metal roofing, we recommend preservation of these historically significant roofing materials. Our roof craftsmen replace missing or damaged roof components with matching heritage roofing materials from our own reclaimed roofing collection or through our historic sources. In projects where the substrate deterioration requires replacement, our roof craftsmen will carefully remove the historic roof materials for re-application.
Historically Authentic Roof Systems
Although the goal of historic roof restoration is the use original materials, in many instances this is not possible. For example, many building codes place restrictions on the use of wood shingles, a common roofing material in 19th century San Francisco Bay Area structures. Through historic research and physical investigation of the roof, Wedge Roofing’s historic specialists can gain insight into the original roof materials, roof top architectural features, roof top design elements and historic roof construction techniques. We can then recommend a historically authentic roof system that accurately reflects the historic character of the building.
From San Francisco Bay Area steeply-pitched Victorian gable roofs, to gentle sloping Bungalow hip roofs and even Eichler Mid-Century flat roofs, Wedge Roofing’s highly experienced historic roof restoration team and exterior construction artisans offer their vast expertise to provide a thorough and thoughtful restoration of San Francisco Bay Area’s architectural treasures. Wedge Roofing’s work complies with Federal guidelines to qualify as “certified rehabilitation” if applying for the Federal Historic Preservation Tax incentive program.
