Why is old roof taken off prior to reroofing?

Old roofs are removed in order to visually observe the underlying deck (substrate) to determine if the existing deck is suitable for reroofing purposes. (top)

If deck displays rot, (typically wood) the area will require replacement of like materials. If a determination that the cause of the rot is other than membrane leakage, a source for this condition will be sought. Often, ventilation of the attic or joist space area is not adequate, adjustments to the ventilation will be proposed, or a roof consultant will be retained to supply the appropriate technical solution.

What does ticketed journeyman mean?

A ticketed Journeyman is a level of competency as established by the Province of British Columbia. In 1992, the Province of British Columbia legislated roofing as a compulsory trade, which forced roofing contractors to maintain a ratio of Journeyman roofers, apprentices and labourers. This only applies to companies supplying an RCABC roof Guarantee, or on public funded work. (top)

Simply, a guarantee is full value insurance on a project if, for any reason, the work fails, for the length of the guarantee period. A warranty is a reducing value policy, where a failure reduces the amount recoverable by the length of service already used. (i.e automobile tires) (top)

Adequate insulation is determined by the B.C.Building Code, but when reroofing does not involve building permits or building code standards, replacement of insulation is determined by thickness of existing. As the new insulations are more performance oriented, insulation value will usually be upgraded with the same thickness of insulation. (top)
