Under One Roof

Canadian Roofing Reference Manual

3.2.6 Additional Precautions

Some of the additional precautions required on re-roofing projects:

  • The roofer should always watch out for insecurely nailed roof decking, rotted roof decking, nails, screws or other items protruding from the underside of the roof deck that are uncovered during re-roofing operation. Pay special attention to deteriorated brick work, deteriorated cant strips.
  • At the end of each day the roofer should thoroughly check the job, assuring that temporary seals are in place, debris guards are in place and protected, hoppers are unplugged, all ladders allowing access to the roof have been removed, and that equipment is properly stored and secured.
  • A roofer must realize that re-roofing usually occurs in mature areas, occupied buildings (schools, apartments) etc. and that the danger of individuals on the ground (or even on the roof), is ever present. There have been many documented examples of people lifting the lid of the kettle and burning themselves with hot bitumen or opening cans of primer and splattering it on brick walls, as well as trying to start mechanical equipment.
  • Re-roofing work may require additional tools and materials not normally used on roofing work.

The items being discussed here are essential to a good re-roofing operation. There are many lesser items that are still important as they represent goodwill and the image of the roofing company you are representing.

  • Profane language is not acceptable on any roofing project.
  • Roof workers should not allow garbage or other debris to accumulate around the property or grounds of the building being re-roofed. All garbage should be collected, placed in a container and disposed of in the same manner as re-roofing debris.
  • If access to the roof is only through the buildings, the roofer should see that the floors, stairs and walls within the access area are protected against roofing debris and other damage related to the construction traffic.
  • The roofing foreman should make sure that their vehicles’ and any vehicles belonging to the crew are parked in acceptable areas. Usually, if the matter is discussed with the building manager, arrangements can be made that are acceptable to all.

Above all, workers should be aware of the building owner’s expectations and ensure an open line of communication.
