Always On Top Roofing built a strong reputation in Abington through 2022 and 2023 on owner Derek Zablosky's personal responsiveness — reviewers describe him picking up the phone directly, showing up the same day or the next for a leak, and finishing full roof replacements in a single day. Specific jobs described include a 60-year-old roof with three layers of old shingles stripped and replaced, skylight leaks fixed for a fraction of what other roofers quoted to simply replace them, and gutter and siding repairs done alongside roof work. Several reviewers say they called multiple companies and Derek was the only one who called back. More recent reviews tell a different story. A February 2026 review described a leaking roof, workers the reviewer called unqualified and drinking on the job, and repeated attempts to reach the company for a repair that went completely unanswered. A separate review said the company took an $8,700 payment in 2024 to install shingles on a garage and house and never showed up for the job, prompting the customer to file a police report to try to recover the money. The Better Business Bureau backs up that this isn't an isolated complaint: it gives the company a B- rating, notes it isn't accredited, and lists one complaint on file for failing to respond along with two negative reviews describing unresolved roof leaks and poor responsiveness. A separate, more minor 2022 review — unrelated to any project — said a company vehicle's occupants threw beer cans out the window while driving. Put together, this looks like a business whose responsiveness has genuinely slipped since its strong early run: the volume of detailed, positive reviews from 2022-2023 is real, but so is a credible, serious complaint about a large payment taken with no work performed and a documented pattern of unanswered calls. A homeowner considering Always On Top Roofing should be cautious about paying any meaningful deposit up front, get a signed contract with a specific start date, and ask directly about recent responsiveness before hiring.
Leaking roof unqualified workers , drinking on the job , reached out to repair leaks no return calls totally ghosted
Had a missing shingle on roof vent from wind damage. Called Derek and talked to him live. Didn't have to leave voice mail.He requested that I text him a description of my issue and he came out the next day and did an excellent job repairing it. Need a roof repair? He's the go to guy.
Derek resolved issue with leaking skylights after other roofers wanted to replace 18 year old skylights and roof costing almost 20k. Returned my call promptly, came when he stated and work hard and continuously.
I called Always after a big rain storm couple of weeks ago. Derek came the same day to assess the situation and we decided for a new roof. There was a slight delay with the project caused by the weather and the material supplier but the work was done and I’m very happy with the outcome. Very professional, good price and excellent clean up afterwards. Great job!
Derek and Always On Top Roofing have done a great job replacing our 60 year old roof (3 layers of shingles!). He showed knowledgeable attention to detail and performed wise preventative maintence where needed. They were fast, quiet and efficient and it was all done in just one day. They also did a good job of cleaning up afterwards. Derek took the time to explain everything beforehand and communicated clearly and honestly. The cost was very reasonable, too. I have referred him to my daughter for her roofing needs and highly recommend him and his company. B. Vance Whitman, MA
