Located at the top of the house just below the roof, the attic is where you should begin with efforts to control the natural drying out of your home.
Ceiling and Floor
Be sure to look up and down while inspecting the attic. If inspecting during the daytime, make sure that the roof is completely sealed and that no daylight penetrates through roof cracks. Focus on openings through the roof such as skylight wells, plumbing pipes, vents and chimneys. Look around and confirm that all surfaces are dry and that there is no visible rotting or mold growth.
Remember that the water may run along the attic floor, rafters, or trusses for quite a distance before coming through the ceiling. Check the bottom side of the roof sheathing, roof rafters, and trusses for water stains. Inspect the floor and make sure it is dry and no dampness is visible. Check for holes, air leaks, or bypasses from the house and make sure there is enough insulation to keep house heat from escaping and causing condensation
Moisture or surface discoloration near the vent is a red flag; find the source of moisture and repair the problem. When inspecting the roof, remove any birds' nests and debris blocking the vents Proper attic ventilation is very important. In most homes, vents are installed along the peak of the roof.
Common Attic Appliances
Periodically, check attic air conditioners, swamp coolers and HVAC (heating, ventilating, and cooling) systems. Inspect around and under these appliances. Look for wear and tear and loose connections. Remember that appliance failures may cause water damage to everything that lies below
If it feels moist, find the moisture source and fix the problem right away. Good insulation is thick, soft and fluffy. Check the insulation frequently, especially after the rainy season. If the insulation is wet, remove it and dispose of properly.
After being wet, most insulation is ineffective, but it will continue to hold moisture for a long time and will create high moisture conditions. Touch it. When damaged by moisture and water, the insulation becomes thin and flat.
Recessed Lights Canisters
The presence of rust and corrosion indicates possible moisture invasion and a potential electrical hazard. Inspecting recessed lighting canisters may provide you with reliable information regarding excessive attic moisture. Stains above or near the wood, or on the insulation around the canisters are a good indicator of moisture-related problems. Consider upgrading old recessed lights canisters with newer, safer ones that include built-in insulation
