Check the condition of the roof framing, sheathing, finish, and the soffit and fascia for signs of moisture problems such as leaks, stains, mould, flaking or rot. Unchecked moisture problems can lead to structural damage, mould and mildew.

Attic Hatch

Attic hatch. Attic insulation. Weasterstripping. Caulking. Heat loss.

If the loose fill or blown in insulation is deeper than the joists, build a crib or shaft around the attic hatch so that the area can be filled to the edge.
The attic hatch is a major source of heat loss. In many cases the hatch cover is nothing more than a piece of plywood. The attic hatch should be treated as an exterior door and be insulated with the same R value as the attic insulation. It also needs weatherstripping and caulking around the hatch trim. To hold the attic hatch cover tight against the weatherstripping install hook and eye bolts.

If there is no access to the attic a ceiling hatch should be installed. The best place for installation would be in the centre of the house where there is more attic height for easy entrance. However, it would be also very visible and for that reason most attic hatches are located in a closet. Attic access makes it possible to work on the electrical system, to bring in additional insulation, if required, and to do the annual attic inspection (sheathing, condensation problems, leaks, stains, etc.)
