They did leave some metal outside which was annoying since we have a dog.

Based on the reviews he read here on Yelp he decided to go with Alt Builders and their owner Dan. He contacted Dan and was who responded very promptly on a Sunday afternoon. Dan came out the next day to size up the job. He was prompt and very knowledgeable about what Jeff was looking to have done. The patio door was ordered and came in approximately 3 weeks later. Dan and his crew were able to come out to do the job within a couple of days and completed the job in a day and a half just like he promised. They cleaned up and the installation went smoothly. The price was very reasonable and Jeff is definitely going to hire Alt Builders in the future to get some doors installed. He highly recommends Dan for any work or repairs you might need.

The Good: - The…read morepre-sale process was smooth. Jake had an excellent presentation - They were the lowest bidder - The roof looks good and I have not had any issues with it. - Their "A" team came out to correct some issues (the flashing looked like it had been installed by a 4th grader) The Bad: - I was told that a PM would be onsite the entire time. In reality he was on site for maybe 10% of the project - My project was sub-contracted out to a another team and I was NOT informed of this. This became a major problem when I started having issues and could not talk to anyone (the subcontractors did not speak english). Note that Buffalo Fresh Roof is NOT the company you are signing with. The contract is actually with Bors Pros Construction - Within an hour on the first day, the protective tarps had come down and there was debris raining down on my deck and flower beds. When the PM showed up at the end of the day, he said that this could not be helped. Of course, that is garbage - they wouldn't put the tarps up if they didn't have a purpose. Also, this is not what I was told in pre-sales. As a side note, I saw the same sub-contractors working on a project down the street for another company a few weeks later. There were no problems with the tarps on that project. - The roofers decided to try to do a u-turn in my lawn and got stuck (I still have the ruts). They then gave me attitude when I refused to try to pull them out using my truck. - I have damage to my gutters, deck, flower beds and lawn. - I am still finding nails around the perimeter of the house To be fair, the PM did knock off the additional cost incurred in replacing some of the plywood. It wasn't worth what I am going to have to spend in the spring to fix my yard, flowerbeds and lawn - I just wanted them gone.

If you need a new roof, try your luck somewhere else. Anywhere…read more Communication is the worst. The quality of work is bad. Materials seem to be ok. To keep the very long story short. Complete roof replacement in November 2024. March 2026 - roof is leaking. It took about 3 weeks for a "temporary fix". Roof is leaking again - "permanent fix". Roof is leaking again - another pair of "temporary fix" and "permanent fix". Each time a new guy comes in, each time they find a new issue, each time "it's fixed for good now", each time it is not. It's been 3 months since the first leak; we are still doing back and forth. And don't get me started on drywall and insulation damage. Who I interacted with * Matthew Z - sales * Tony G - project manager (install and one of the fixes) * Matthew - fix * Elijah Simon - fix * A couple more guys whose names I didn't write down for other fixes and assessments * Bob - Director of production in Buffalo area - for coordinating fixes and drywall repair * Charlie Ray - General manager - for one text message of "we are better than this" kind with complete ghosting after that --- Now, to the long story, if you are interested. Installation (November 2024) The only two instances when I was able to speak with Tony (PM) were the call in the morning "we will be there and start in 30 minutes," and "let's go look at the roof and sign the bunch of papers" in the evening. Despite sales promising constant communication and updates. Despite multiple assurances by sales, scheduling and website of "On arrival PM will introduce themselves to you and review the job details with you". It never happened same as "PM will give you their phone number". Same stuff with "communicate any change orders with you (i.e. Lumber Charges". New lumber was brought in without any interaction with me. It was 100% needed, but it would be good to be in the loop. Cleanup was decent, but not super thorough. I collected about a 64 oz jar's worth of nails in the days after installation, including ones on a driveway. Plus some loose nails in the spring in gutters, in the attic, and on the lawn. A whole 2025 flew buy without apparent incidents - shingles are still on the roof, no apparent leaks. March 2026 - a small leak appeared. But I have a 20- or 25-year warranty, right? Yeah... And from here on, it is an epic story. * I call them, talk with them, check the forecast (no rain in the next 10 days). I agree that the leak is small, there is no rain in the forecast, and I can wait about a week for them to fix this - no problem. * Two weeks later - no call, no text, no email, no mail, no fix. But now the leak is bigger. I collected about 7 gallons of water before being able to redirect the flow to the toilet (the leak is in the bathroom) * It takes another two calls and escalation up to Charlie Ray (general manager) to get somebody for a fix next day * Meanwhile, a part of the drywall on the ceiling is soaked through and crumbles in my hands with zero effort * The next day a guy appears. inspects stuff inside and outside. Says, "I gotta do a temporary fix from the inside. In the next couple of days, the office will contact you for a permanent fix outside". What does he do? He patches the suspicious area with sealant, some tape, more sealant, and more tape. "That should do it for now. Here is my phone; call me if it leaks again" * Office does not call in the next day, two, three, a week. * I call again and get "your ticket got closed. The fixer guy closed it and said that the fix is done" * Meanwhile, it starts leaking again * another guy comes in, does a fix outside * The office schedules a drywall guy to fix the whole * Drywall guy patches the whole and says, "I'll be in next week to paint it" * Next week it leaks again. same place. patched drywall is soaked wet again (not to the point of collapse this time) * another round of dance with the office * another guy comes in, checks the roof outside, and without any word just drives off * I go to the office physically. Meet with Bob and Tony. Tony "will be fixing it for good tomorrow" * Next day, Tony and one other guy are here; they replace the pipe boot and a patch of shingles. Turns out the pipe boot was much bigger than it needed to be, "that's why it was leaking". But the new boot "will fix it for good." Worth mentioning that Tony was the original PM on installation. * About two weeks after that, the roof is leaking again in the same place. * Another round of me going to the office, meeting with Bob (who promises a fast fix with the best fixer guy they have "today or tomorrow"; and bunch of other stuff) * "Today" the best guy couldn't make it. * The next day, "the best guy" couldn't make it to me either, so they sent another "super fixer guy" from Rochester (I'm in Buffalo) * He fixed something and was so eager to run away that I basically needed to catch him * A week later, and I have not a peep about drywall. But fix (#4) holds (for now) 06/19/2026
