Pre-Project Assessment

What we assess first

Before recommending a roofing solution, we assess the existing building, roof condition and operational requirements to determine the most suitable replacement system.

Roof & Structure

✓   Roof sheeting condition and corrosion

   Structural support conditions

   Material compatibility

   Flashings, cappings and penetrations

Performance

✓   Drainage and box gutters

   Roof ventilation

✓   Insulation

✓   Skylights and natural lighting

Building & Operations

✓   Access requirements

✓   Building operations

✓   Long-term maintenance considerations

This assessment determines whether a like-for-like replacement is appropriate or whether upgrades to drainage, insulation, ventilation or detailing are required to improve long-term roof performance.
