Lukasz of LGC roofing came the same day we called him, gave us an estimate for roof replacement. It was reasonable, and he explained the whole process, materials, etc. His team did a very professional and thorough job! I would highly recommend them.

I called LGC Roofing for an estimate. They answered my call and within a day they came, inspected the roof and gave me a written estimate including when they could do the work. The crew came on schedule, with all necessary tools and materials, worked two long days, and left the site clean. All work was done as promised and on schedule. We had two heavy rains shortly after, and no leaks! Awesome job! Thank you. Lukasz!

Lukasz, owner of LGC Roofing, is one of the most courteous, professional, prompt on time person I have come across !!! He is HONEST and by no means a rip off!! I feel I owe him more money for what he charged me to fix my roof!!! When you put a call into a company at 9 am and they are at your house at 2 pm knowing expected rain in the amount of 5 inches is due and they want you taken care of so you have no further damage..that is saying a lot for ones character!!!When you live at a shore town..I think everyone will attest to the fact that it is extremely hard to get a worker to show up without waiting for long periods of time and then the work sometimes is questionable. Not so with Lukasz..do yourself a favor and put LGC Roofings number in your speed dial for any roofing or siding problems..you won't regret it!!!

The strong wind blew off the ridge cap and few shingles from our roof. It was going to rain and the water was dripping inside from the attic.
I stumbled upon this company and found great reviews. Called them and told Lucas about the issue and he was very professional and told me he will stop by the same day to take a look at the roof. As promised, showed up on time the same day I called, inspected the issue by flying his drone on top of our roof to see the issue and sent his men next day to repair it.

Excellent service, and would use them again in future.

November 2019 ,House with major damage sat for over a year due to insurance claim problems and the pandemic. I contacted dozens of contractors and roofing companies and nobody was willing to help or wanted anything to do with this job. I contacted Lukas at LGC in March 2021. Structural damage, roof and gutters were all repaired in 3 days. I wanted to personally thank Lukas and everyone at LGC and Advance Gutter for their help. From start to finish they did an excellent job of restoring my parents house after a long and trying ordeal.
