During monsoon season in Arizona, we can get a lot of rain and humidity. The first thing that gets hit with the heavy rainfall and high humidity is your roof. Water can cause a lot of issues to your roof if moisture gets trapped. To avoid this, it’s best to waterproof the roof. You’ll want to waterproof under and over the shingles.  

Waterproofing Under the Shingles- The most common roof type are shingle roofs. These shingled roofs should contain a strong waterproof material like tar paper or roofing felt that will go between the rafters and shingles. You can also waterproof under the shingles using thermoplastic polyolefin.  

Waterproofing Over the Shingles- When you waterproof the shingles, you can get a few more years without having to replace the roof. You’ll want to get a waterproofing compound and spray, roll, or brush onto each shingle. You can go with an oil-based compound that lasts longer or a water-based compound that is more environmentally friendly.  

It is important to note that these both need to be done for your roof to be the most waterproofed as possible. Start with hiring a roofing contractor to waterproof under the shingles. They can safely and professionally do this for you. Then, either they can waterproof over the shingles or you can if you’re not concerned about safety.
