Oatey 14136 Rain Collar 1.5"-3" No-Calk Roof Flashing, Black

This rain cover is simple in operation, easy to install, fits several size pipes, and is reasonably priced. The cover stretches over the vent pipe. I bought the up to 3" rain cover. It stretches open unmodified for pipes up to 2" in diameter. For 3" you'll need to cut out some material. The area to cut away is already molded into the rubber (look on top and the under side). The instructions are also molded into the rubber of the rain cover itself (top side), and you can even see it in the photos posted by Amazon and users. This boot does not require sealant because it fits tightly on the pipe; however, if the cover will be in contact with any sealant, make sure it's not petroleum based as petroleum will degrade the rubber. Silicone will work fine. I was very pleasantly surprised by how easy it was to install, especially considering I was 3 stories up on a very steep roof and anxious to get down.

Very easy installation with no tools required!Awesome product,high quality material

Forget replacing the vent, just slip this over the top of the pipe and slide it down. Works great, cheap and easy. If your vent is bad, your roof is going to need replacing at some point, wait till then and replace all your vents.

This rain collar fit snugly over a 2" ID vent pipe. I installed the collar during cool weather and did need to warm it with my hands a bit to get it to stretch over the pipe end. A concern is that rain flowing under the collar could get to cracks in the old seal underneath. So, this collar alone does not seem to be a 100% solution.

Fit our roof vent pipe perfectly. Good price and well made.

Exactly what we needed to fix roof vent pipe leak due to crack in existing cover. Easy to install, thick material.

Shipped quickly & with NO issues. Pleased with the quality & price of product. Fit was accurate & it was super simple to install. It serves it's purpose well but longevity/durability of product are yet to be determined (time will tell). Would purchase again if needed.

I installed these rain collars on five vent pipes. The outside air temperature was 48 degrees. Two pipes were 2.5" OD (2-3/8 measured), and three were 2" OD (1-7/8 measured). The 2" vent pipes were easy. The 2.5" pipes were a little more challenging, but follow the tips below, and you too will be successful.Installation:1. Get yourself a bucket of Very Hot water and toss the rain collars in - letting them soak a bit to soften them up before installation.2. Find an empty spray bottle and fill it with .5oz of dishwashing liquid and 8oz of water. Don't shake it; just swish it around to mix the water and soap.3. Climb up on the roof with your bucket (collars still soaking inside) and spray bottle. It helps to have someone hand you the bucket and bottle once you're on the roof.4. Spray a liberal amount of soapy water onto all sides of your vent pipe. On 2.5" pipes, be sure to get some all the way around the top of the vent pipe opening.5. The collars will slide right on and down a 2" pipe. Be sure not to force it down too far, as you want a nice smooth surface for the water to run off.6. 2.5" pipes are a bit more fiddly. Carefully stretch the collar opening over the top of the vent pipe using just enough force to get it on. Don't pull too hard, or you'll deform the shape of the collar on the bottom, and then it won't seal well to the flashing. If you do make this mistake, as I did, get it seated as best you can. Then, go back inside the house and refill your bucket with some really hot water. Climb back up onto the roof with your really hot water and pour about 1/2 of it onto the collar. Then, gently prod it back into the correct shape. If it still isn't sitting correctly after the first try, pull it up an inch or so, then use the rest of your hot water to get the collar very warm and take another crack at it. It's easier the second go-round.7. Carefully climb back off the roof, put your bucket, bottle and ladder away. Grab your beverage of choice, go back outside and admire your handiwork - knowing that you just saved yourself a minimum of $150.00!
