Repairs, Replacement, or Reroofing?

Whenever possible, the Wedge Team will extend the life of your roof with flat roof repairs or flat roof restorationIf a new roof is necessary, the option for roof replacement or reroofing is dependent upon the condition of the existing flat roof and local building codes. 

  • If reroofing is an option, we will install the new flat roof directly over the existing roof.
  • If roof replacement is required, we will tear-off the existing roof to the sheathing boards and then install the new flat roof.
  • Typically, the installation of Spray Foam Roofs does not require removing the existing roof.
  • If the existing roof needs to be removed, Wedge Roofing has the resources to quickly and safely complete the tear-off while protecting your property.

Flat roofs were introduced in California during the 1920s with the “International Style” of architecture. The movement’s love for modern cubism favored the calming horizontal lines of a flat roof over the austere vertical lines of classic pitch roofs. The popularity of the California Flat Roof rose during the post-war building boom, as seen in the design of Eichler homes. With scant rain in Southern California, flat roofs worked well. However, Eichler homeowners in rainy Marin County soon discovered their flat roofs were prone to leaking unless installed with precision.

In the 1970s, Wedge Roofing began working on Marin County Eichler roofs in San Rafael and Lucas Valley. Our roof experts devised a technique to improve the watertight performance of these beloved homes. After years of frustration with their leaky roofs, our clients were thrilled to discover that an Eichler flat roof installed by Wedge Roofing does not leak.
