A Recovery System is one where a second roof is installed on top of an existing one.
There are a few key criterion that need to be addressed in the design of a successful long-term recovery system including the ability of the structure to handle the additional dead-load as well as the crucial need to be sure that you do not trap any existing moisture in the system.
A roofing contractor might perform a full moisture scan of the existing materials to be sure that the existing roof is a suitable substrate for the new materials. Once the existing roof is checked for moisture, any surfacing is removed and a layer of insulation is attached through the existing roof and directly into the structural roof deck. At this point, you have a number of options available as for what you can use as the roofing and waterproofing layers.
Similar to a replacement system, you will ultimately choose from the four major product groups: Conventional Built-Up, Modified Bitumen Built-Up, Thermoplastic Single-Ply, and Thermoset Single-Ply.
Commercial Roofing Options
When contemplating reroofing projects, building owners, townhouse and condominium associations need to be well informed. To protect their interests and obtain a wise roofing investment, it is very important to know what the existing roof assembly consists of and why it is failing. Selection of a new roof system and its varying features must be made very carefully. When receiving proposals from roofing contractors make sure that it is clearly stated whether the proposed project work is a roof replacement or roof recovery.
