    Selection: I got 3 roof quotes for some suspected moisture…read moreinvasion and roof issues discovered by another contractor. Both We Get High and V&K gave me around the same quote for a total roof replacement (around 8k, not including plywood prices) and Summit quoted me an eye watering 24k (including materials). I went with V&K for several reasons: - The two workers who arrived were knowledgeable about the roof, patiently looked at the areas I was most worried about, and called the office immediately to discuss their findings - I really enjoyed how attentive and quick the quote process was; Karol was great to work with - I was treated with respect as a female homeowner and nobody asked to speak to my husband (which is often times a problem) The results: From both a house inspection and other contractors, I knew that the roof I have was potentially not done by pros, and there were more problems than expected: - All the facia had to be replaced because of rotting and water ingress - The infrastructure underneath the plywood was shoddy/nonexistent and V&K added extensive plywood support underneath - They also did all the vents and flashing and the ... metal cover things underneath the eaves - The plywood costs were already going to cost around 4.5k but the additional facia costs were an unexpected addition. The total came to about 14k. I have a huge, flat-ish roof, and the price compared to other homeowners and people I spoke to, sounded about right. That said, Karol's team also replaced all my gutters with the facia and were incredibly considerate about all the other things I didn't even think to worry about, and I felt like they threw in a lot of things that were not explicitly charged (2x4 plywood for infrastructure etc) - You can hear each shingle nailed in with precisely 6 nails each - Karol supervised all the work carefully - They swept all the work area with magnets to make sure I wouldn't step on a rusty nail or pop a tire on them, I really appreciated the careful cleanup - Everyone was incredibly hard working and efficient, there were no long lulls or breaks for days so I didn't have to worry about the weather - The team documented all the roofwork in pictures so I can see what was done, when I get a chance I'll clean them of EXIF data and post it I'm very pleased with the job with the team and will be recommending them to all my neighbors. Also, as a security person I want to mention some older reviews where it looks like there were a few victims to impersonation scams--if you read my other reviews this has been happening to lots of legitimate businesses in the area, including two restaurants that I frequent. A few tips: - Always meet with contractors in person at least once - Have a signed contract and negotiate the work in detail - Check that the phone number you use for Zelle matches the yelp profile - Ask for proof of insurance--again, match the company you're working with, with the proof of insurance - Zelle payments will hold the funds for 3 business days, so pay the deposit immediately before workers arrive (and rescind payment if they delay--you can always pay them again later) - Be mindful of your monthly maximum for the Zelle payment (it's a rolling max so in the worst case scenario you wouldn't be able to finish paying for your whole roof replacement unless you use a second account, or a check) Is this fool proof? No, there will always be very smart conmen but I can attest that this is a legitimate business and they did legitimate (good quality) work for me.

    They came on time and did a great job cleaning my gutters. They were very quick. Also we're…read moreflexible with their quotes. They took Zelle and were friendly, also were kind enough to do some leaf blowing without any charge and cleared my yard.

    We had Impact Roofing replace our aging roof a month ago. We are so glad they were able to fit us…read morein before the major snow/ice storm as our old roof was wearing thin. The quote was competitive. The team was fantastic. Delivered materials the day prior and showed up promptly to begin work. Everything went incredibly smooth--the crew finished by late afternoon. Mason was friendly, professional, and available for any and all questions. The biggest relief is knowing we went with an experienced roofer that guarantees the quality of their work with an outstanding warranty. We are so glad we went with them over other options in Frederick. Looking forward to not needing to replace this roof again!

    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.

They came out and replaced the vent and associated shingles. Great fix! Now, 25 years after moving into this as a new house, I needed a new roof. I got two estimates, one from Marshall. Marshall's representative, Doug, was so thorough and professional in his reprensentation to me and offered a solution re moviing the attic exhaust fan closer to the eave and keeping the ridge vent. The other estimator suggested removing the ridge vent. I wasn't comfortable not having a ridge vent. I again went with Marshall. It was a two day job. They dedicated a more than sufficient crew to the job. The guys were so attentive to protecting against falling shingles as they were stripped from the roof. In short, they did an excellent job! I had absolutely nothing to be concerned about with Marshall's professionalism as a company. And, there cost was lower than my other bid. I only got two bids as my past experience with Marshall and with Doug's representation made it a no-brainer! If you need a roof, go with Marshall.

    I completely trust Marshall Roofing. They have always been thorough and fair…read more Today was the second time I had Marshall help with a roofing issue and, true to form, Jose P. called when he was en route, arrived on time and got right to work. When he discovered a problem that was not foreseen by the estimator he had to run out to get a part but came back promptly and finished the job on schedule. Although this specific element was not included in the original estimate, Jose installed it without fuss and did not charge for the part or his extra labor. Where can you find that kind of responsibility these days? I would never call anyone but Marshall!

He had different crews specialized in each project, one for windows/doors and another for the siding. We had specific ideas and designs that we wanted. Fredy listened and was willing to accommodate and provide us with options. He was never trying to push products or ideas on us and we never felt pressured on anything. We loved the doors/windows crew. They were on time, respectful, friendly and they did a great job. There were a couple of hiccups with the siding, but Fredy came out every day and we came up with fixes. We've worked with numerous contractors across various specialties. There was always some sort of frustration or argument with each project because the crew cuts corners and/or the owner is unwilling to listen to what we wanted. Fredy is the only contractor/business owner who we feel truly wants to listen and make his clients happy. He is happy to work with you to get to a final project that you are happy with without getting defensive and letting pride get in the way. On top of that pricing was reasonable. He is not the cheapest but he is nowhere near the most expensive. Highly recommend Fredy and Designer Windows and Siding.
