    ****Update awaiting installation of exhaust fan (additional $425) that Garrett believes is causing our "new" roof to leak from condensation. Except it only leaks when it rains! Horrible follow through.

    Reply from the business

    Hey Rita, so sorry to hear you have had trouble with your bathroom leaking! Leaks can be extremely frustrating for everyone involved. We do believe a new fan will help with your situation. Often if the roof is doing its job and you still have issues the next culprit to check is the bathroom vent because moisture can form inside the vent pipe and then water flows down the duct into the home. The bathroom fan pushes air up and out, while the air temperature outside differs so much that condensation collects, similar to a glass of water with ice on it sitting on a picnic table outside would collect water. That water shows up on the bathroom ceiling but doesn't come through the shingles. Rest assured the roof itself has been rechecked and we will continue to help problem solve with you. Meeting set for today!

    Working with Double J Roofing has been an amazing experience! Their sales team is friendly, professional, and quick to respond. As a realtor, I needed a roofing estimate during a tight inspection period, and they were able to get out to the property the very next day. What stands out most is their excellent communication and follow-up. They truly care about their clients and make sure every question is answered and every need is met. I was so impressed with my experience that I referred them to another real estate agent, and she had the same positive experience. I’m incredibly thankful for Double J Roofing and their warm, customer-focused approach. They make the process easy, reliable, and stress-free. I highly recommend them to anyone looking for a local roofing company they can trust!

The latest post from this business

Posted by Double J Roofing & Contractors LLC to their own Google profile 17 days ago. Their words, not ours.

Hey, I’m Julia — one of the owners of Double J Roofing. 👋 I’m learning to go from a company I’ve worked in to one I work on… so I’m trying to figure out LinkedIn and all that jazz. My plan…. you’ll see a little bit of everything: business, leadership, construction, the wins, the challenges, and probably a few things I’m still figuring out along the way. I’ve learned that owning a business isn’t just about roofs, siding, or hitting the next revenue goal. It’s about people, relationships, building a team, making hard decisions, and constantly asking yourself: What’s your potential? What’s their potential? Whats our potential? So I figured it was time to start sharing more of that side of the journey. Welcome to our page. Let’s see where this goes. 💚 #doublej #roofing #roofers #siding #contractors #stpeters #stl #stlouis #workhard #localcontractor #ofallon #chesterfield #wildwood 6 days ago
