Procedural Specifications

Workers’ Safety comes first: Proper planning, precautions and safety training help maintain life and health. All workers, whether working here or elsewhere must recognize and accept the safety measures required to do their jobs. T.R.I. management makes a concerted effort to educate and raise safety awareness amongst its workers. Training courses focus on Fall Protection and the use of ladders. Courses are performed at our office at 200 Unwin Avenue. Workers should always be looking to eliminate hazardous conditions by selecting spots where ground is firm, reasonably level and free of debris. Workers should be aware of any live electrical wires in the work areas.

Property: Before the first shingle is removed it is important to take steps to protect the building and surrounding area from damage and dirt that can be caused during the job. The preparation of the job site is a key element to the success of our installation and job site procedures.

T.R.I. shall protect the windows, doorways, trough systems, surrounding grounds and foliage with tarps and plywood. Neighbouring properties are also included as needed. Extra tarps and rolls of asphalt saturated paper are kept in vehicles in case of sudden rain storms.

Preparing the Roof Deck: The roof deck is the structural surface over which the roofing materials are applied. Wood decks should be constructed of seasoned lumber, securely fastened to joists, beams or their supports. The surface should be smooth and firm, free of cracks, knotholes, depressions or other defects. For the purpose of roofing the roof deck must perform key functions such as:

  • Structural support
  • Dimensional stability
  • Hold uniform loads such as heavy snow
  • Provide resistance to wind force
  • Anchor the nails
Applying shingles to a roof deck that is considered to be unacceptable by the manufacturer will void their warranty. The manufacturer will not take responsibility for the following:
  • Poor deck design that causes damage to the roofing materials
  • Damaged shingles caused by penetrations such as partially driven nails
  • Application of roofing materials overtop of wood deemed unacceptable
