If you’re like most homeowners, you probably don’t think much about your attic. But if you have problems with moisture or heat, your attic is a big part of the solution.
Attic insulation is key to keeping your home comfortable and energy efficient. But if you have water infiltration or ventilation problems, your insulation won’t do you much good. That’s where attic waterproofing comes in.

There are a number of different products on the market that can help you waterproof your attic. Some are simple and inexpensive, while others are more sophisticated and expensive. But all of them can help keep your home dry and comfortable.
Here are a few of the most popular attic waterproofing products:
- Roofing tar or asphalt: This is one of the simplest and most affordable ways to waterproof your attic. It’s a bit messy, but it’s an effective way to seal up cracks and seams in your roof.
- Roofing membrane: This is a plastic sheet that goes over your roofing material to help keep moisture out. It’s not as messy as roofing tar, and it’s a bit more effective at stopping water infiltration.
- Foam insulation: If you have a lot of insulation in your attic, you may want to consider using a foam insulation product to waterproof it. These products form a barrier against moisture and help keep your attic cool in the summer.
- Roof ventilation: If you have problems with moisture or heat in your attic, proper roof ventilation is key. There are a number of different products on the market that can help you improve your attic ventilation, including roof vents, turbine vents, and soffit vents.
No matter what product you choose, make sure you read the instructions carefully and follow them to the letter. Improper installation can actually make your problems worse.
