Roof Covering and Deck
A visual inspection of a roof deck or roof covering will indicate its condition, and the adequacy of routine maintenance. A roof's condition can often be observed from the underside or from a roof access hatch. Pitched roof covering condition can often be observed from the ground; however, low-sloped roof coverings need to be observed on the roof. Deteriorating roofs will not be able to resist water ingress or weight stress from hail or snow.
|Steel roof decks showing signs of structural corrosion.||Roof decks showing no significant visual signs of duress.|
|Gypsum or cementitious wood fibre roof decks showing signs of water damage.||Perimeter edge metal securely attached to the building.|
|Perimeter edge metal flashing of low-sloped roofs (without parapets) that is not rigidly secured to the building.||Preventative roof maintenance program in use.|
|Blistering or soft spots indicating wet insulation below the roof cover.|
- Implement a roof preventative maintenance program. As a minimum include: debris removal; cleaning roof drains, scuppers and gutters; replacing missing drain covers; adding or redistributing ballast; securing loose roof perimeter flashing and securing loose rooftop equipment.
- Use experienced roofing contractors to conduct an annual roof inspection. Noted deficiencies should be promptly corrected. In high-wind regions, this inspection should be conducted before the high-wind season begins.
- In high-wind prone regions, consider face-fastening of perimeter edge metal to provide a visually secure connection to the building.
