The biggest relief is knowing we went with an experienced roofer that guarantees the quality of their work with an outstanding warranty.

Bottom line up front: Impact Roofing is not a company that takes hands-on pride of their work. They…read morewill send a team of people who barely speak English to do your project with no supervision. The company will go hands-off as soon as they get your deposit. I almost never write bad Yelp reviews and I have been sitting on writing this review for a while but I had to because I am still so upset with the quality of service. When giving me my estimate, they sent a real professional to actually survey the property, go up on the roof, take measurements, etc. I had a really good feeling about the company. However, the person who gave me the estimate quit the company and I was reassigned to someone else who never physically came by to see the property. On the day of the installation, the team that they sent had no familiarity with the specifics of the project (which was attic insulation, gutter installation and rain barrel installation). I had to explain everything to them all over again, like they'd never heard of it before. It didn't help that they didn't really speak English and I had to show them what a rain barrel was with hand gestures. The workers installed my backyard rain barrel backwards, and my front yard rain barrel upside down. They took bricks from another part of my yard to mount my rain barrel without asking. The worst part by far: One of the workers, without asking, cut down my Virginia creeper plant that I had been growing and training for three years. It covered the front of my house and attracted birds and butterflies in the spring. Now it's destroyed. There was literally no reason to do this, he didn't ask for permission or anything (he said "it's poison!" when I asked why he did it; it's not, it's a harmless native plant). My house used to be unique, now it looks like every other house on the block. This last offense was intolerable, I called the company and demanded they sent someone down. They ultimately discounted the project by $2600, which was fine but did not compensate me for my loss. This was the first time any supervisor actually came to the property. It was clear the supervisor didn't know the workers at all, and he couldn't communicate with them any better than I could. The management had no interest in coming by to check work after it was complete, either. I had to reach out to them to request that they do so. They were perfectly content to just let their workers do it and leave for the day. Ultimately, they did the job that was on the contract, hence the two stars: they insulated my attic, installed gutters, and installed rain barrels. But everything else was a terrible experience. I wish I could undo hiring them in the first place.

Because it is a big project, I actually contacted at least 7-8 companies for quotes and ended up using American windows because of their best price and the best windows brand and glass package.

The team went out to install 40 windows and they absolutely did an excellent job. They were super friendly and professional. I'm very neat and detailed so they made sure all windows are cleaned and properly installed. After installing, they vacuumed and even mopped the floor for me. I'm very pleased with their work !

Corley replaced my flat roof more than 5 years ago. It's still fine! The reason I'm writing my…read morereview today is that I was recently reminded me that we need to value and recognize our honest and reliable service providers. Here's why I put Corley into my strongly trusted set of service companies... 3 guys from a DIFFERENT company stopped by saying while working on a neighbor's roof they saw a flashing on my roof that needed to be nailed down. I told them to go ahead and when they came down, they said my chimney cap was cracked and there was a good deal of rotting of the wood frame inside it. They had photos and quoted repair options from $7K to more than 3 times that amount. I called Corley to get their opinion, they came out within a day or two, and they said my chimney cap was 100% fine! It turns out, my chimney from my 100+ year old house doesn't even have a wooden frame inside it. And they pointed out a different problem, a real one -- I had a metal chimney flue and they saw it was rusted/cracked, but that wasn't in their menu of services . So not only did they save me from the fraudsters, but they saved me from potential damage from the damaged flue which I had fixed. And they didn't charge me a dime for this roof check. There was a time also within the first 5 years of my roof that some flashing or something slipped, and I did have a small leak. I called Corley, the roof was still under the 5 year warranty, and they fixed it promptly. So thank you Corley. When I hear people needing a roofer, I refer them to you.

My project was complicated because my 1980s drywall shafts were the wrong size for modern solar blinds. Instead of just "making it work" or creating a huge mess with drywall dust, Zach proposed a brilliant custom solution: building a clean birch veneer box with custom trim. It looks stunning and kept my house completely dust-free. What impressed me most was Zach's integrity. During the install, a small piece of my old plastic molding snapped. Instead of ignoring it, Zach took full ownership and replaced the trim on both skylights with upgraded foam-backed wood molding at his own expense to ensure everything was airtight and uniform. It is not a simple fix but an upgrade, for free. See the attached before/after pictures and the broken plastic. Like most customers, I contacted a few contractors before selecting Winfield Builders. Their price is VERY reasonable, and the communication through Yelp was professional and transparent. It is rare to find a contractor who cares this much about the details. If you want a crew that is honest, skilled, and delivers a beautiful finish, call Zach. 1000% recommendation!

The larger size has made a huge difference, as they're less likely to get clogged. My home is in good shape thanks to Winfield Builders!

For the first time I realize I had been hearing a fair amount of outside noise (which I'd apparently gotten used to), because these windows/doors are soundproof; now I don't hear anything at all from outside! And even better, the windows are easy to open, and my sliding glass doors actually slide well in the track, and are not shaking and drafty when it's windy outside -- major improvements from my old, builder-grade, 20+ year-old windows/sliding door. Further, the service crew was excellent -- careful, kind, professional, efficient, and they cleaned up everything afterwards. Roger, the foreman, has been doing this work for almost 30 years, and Jose, who single-handedly carried in/out the windows/doors, has been doing this work for 10+ years. I didn't get the name of the quiet third service person who was mostly outside and on the ladders, also very efficient. fyi, they did mention that working on the 4th floor of our condos from ladders was a bit more challenging as the original builder-grade windows had been made to fit by being packed/taped in place from the outside, which necessitated them having to actually break some of the glass to be able to pull the old windows out. But they did it - and did it well. Finally, Shaun, the project manager who gave me my estimate and oversaw the project from estimate, HOA approval process, to completion, was great. Highly recommended.
