Montreal's (CMI) certified home inspector, Robert, inspects Attic spaces.
The Attic An attic is an unconditioned space between the roof and the ceiling, and can be between the roof ceiling and walls of the building’s inhabited or habitable space. In a small house with a pitched roof, the attic is usually partially or fully accessible. In a house with a low-slope roof, it may be inaccessible or virtually nonexistent. When there is an accessible attic space inspecting that space is highly recommended.
Roof Leaks: Look for signs of and monitor water leakage from the roof above and try to locate the source. This may be difficult to do beneath built-up roofs or loosely laid and mechanically fastened single-ply roofs, since water may travel horizontally between layers of roofing materials. from my experience in the trades, roofing being one, most often water enters penetrations, protrusions or flashed areas. Most all roofs will leak eventually but that is no indication that the roof requires replacement. That means it is time to have a professional fix the leak and assess the roofs condition. professional roofers and roofing association recommend "yearly roof inspections" followed by/including annual roof maintenance and roof tune ups when required. Depending upon the material a professionally installed roof covering following the manufacturer's recommendations roof should last 20 to 30 years with annual inspections, maintain and roof tune-ups. The life of your roof is directly related to how often it is inspected, and how quickly small problems are identified and repaired.
Attic Ventilation: Signs of inadequate ventilation are rusting nails (in roof sheathing, soffits, and drywall ceilings), wet or rotted roof sheathing, and excessive heat buildup. Adequate attic ventilation can be measured by calculating the ratio of the free area of all vents to the floor area. The free area of vents is defined as their clear, open area. If a vent has an insect screen, its free area is reduced by half. The free vent area-to-floor area ratio should be 1 to 150. If the calculated ratio is less, consider adding ventilation, especially if you’re in a hot and humid climate.
If the attic also contains an occupied space, check that the ventilation from the unconditioned, unoccupied areas at the eaves is continuous to the gable or ridge vents. Also check that the free area of eave vents is approximately equal to the free area of ridge or gable vents. If ventilation appears to be inadequate and additional vents cannot be added economically, consider adding mechanical ventilation.
Vents, Birds and Rodents
Vents, Birds and Rodents: Make sure ventilation openings are clear of dirt and debris. At larger ventilation openings on a building’s exterior and where louvered grilles are used, such as at gables, check for the presence of 1-½-inch-square 14- or 16-gauge aluminum mesh bird screen. If there is none or it is in poor condition, consider having new bird screen installed.
Plumbing Stacks and Exhaust Ducts: All plumbing stacks should continue through the roof and should not terminate in the attic. The stack pipes should not be loose, broken or damaged. Exhaust ducts should not be kinked, broken or damaged. They should not terminate in the attic but should continue through the roof, gable or wall.
