The short answer
Stop the Water First
Before drying anything, find and stop the water source. If the leak comes from a pipe, turn off the water supply at the shutoff valve. If it is a roof leak, place a tarp over the damaged area or use a bucket to catch drips. In Layton, keep your shutoff valve location written down so you can act fast in an emergency.
Once the water stops, remove any standing water with a wet-dry vacuum or towels. Be careful on attic floors, as they may be slippery or unstable. Wear gloves and a mask if you handle wet insulation, as it can irritate your skin and lungs.
Remove Wet Insulation and Debris
Wet insulation loses its insulating value and can hold moisture for weeks, leading to mold. If the insulation is soaked, remove it and dispose of it properly. Check for any debris or soaked wood that could trap water. Use a flashlight to inspect dark corners and crevices.
If the insulation is only damp in a small area, you might dry it with good airflow, but it is often safer to replace it. Wet fiberglass or cellulose can compress and become a breeding ground for mold. When in doubt, remove the affected section and let the area air out completely before putting in new insulation.
- Wear gloves, a mask, and eye protection
- Use a wet-dry vacuum for standing water
- Bag and remove soaked insulation
- Check for hidden moisture in wood beams
- Dispose of wet materials outside your home
Set Up Fans and a Dehumidifier
Good airflow is key to drying an attic. Open any attic windows or vents to let humid air escape. Place a box fan or two near the leak area to keep air moving across wet surfaces. A dehumidifier can pull moisture from the air, especially if the attic is closed off from the rest of the house.
Run the fans and dehumidifier for at least 48 hours, or until the wood feels dry to the touch. Check the humidity level with a moisture meter if you have one. If you do not own a dehumidifier, you can rent one from a local tool store or hire the pros for a more thorough drying job.
When to Call the Pros
If the leak is large, the attic has extensive water damage, or you see mold, it is wise to contact local water damage pros. They have industrial fans, dehumidifiers, and moisture detection tools that can dry your attic more effectively. They can also assess structural damage that might not be visible to you.
Before you call, know that the cost depends on the extent of the damage and the drying time needed. The pros can also help with leak detection to find the source if it is not obvious. If you have insurance, check your policy to see if attic water damage is covered. Policies vary, and your insurer decides what is covered.
- Large or ongoing leaks
- Visible mold growth
- Wet drywall or sagging ceilings
- Unusual musty odors
- Electrical wiring or outlets exposed to water

How long does it take to dry an attic?
It depends on the amount of water, airflow, and humidity. With fans and a dehumidifier, a small leak may dry in 2 to 3 days. Larger leaks or trapped moisture can take a week or more. Check wood with a moisture meter to be sure.
Can I use a regular fan to dry my attic?
Yes, a regular box fan can help circulate air. Place it near the wet area and point it toward an open vent or window. For better results, use a dehumidifier alongside the fan to remove moisture from the air.
Should I remove all the insulation if it got wet?
If the insulation is soaked, remove it, as it can hold moisture and lead to mold. Damp insulation might dry if the area is well-ventilated, but it is often safer to replace it. Check for any signs of mold before deciding.
