I'm fairly stingy with my ratings so take this Good rating as sign of a quality roofing company who stands by their work. Even a Good roofing company is hard to find in Philadelphia. I have found Marcy the owner is to be straightforward and honest, and though she can be a bit brusque at times, as she is in the Philadelphia roofing business I can understand. Their pricing is reasonable for quality of work. No roofer is cheap and if you apparently find one, don't trust them. We have a complicated roofscape (skylights, large AC unit mounts and penetrations, and major crickets required to clear drainage obstructions) and some leaking problems that predate our ownership. Castelli, and particularly their foreman Jimmy, have been generous in attending to drainage problems that may or may not have been a result of their work. I appreciate their work and the efforts made to help us negotiate our finicky roof.

Hired them for a balcony roof replacement and I couldn’t be more satisfied with the work. From start to finish they were professional, providing detailed scope of the work to be done, pictures before and after - very transparent and professional. Thank you!

Marcy and Jimmy were quick and easy to work with when we had an issue with our roof.

We bought a new construction house and have been having leaking problems ever since (3years later) with our piolet house. Jimmy came out to inspect and was able to spot the problem and provide options for us. He even talked to us about future issues he could spot to get ahead of it. It's hard to find an honest company that care about their customers to go above and beyond what was asked. They were SO quick to do the work, made zero mess, and were very respectful coming in/out of the house. Can't recommend them enough!

I've been meaning to post a review of Castelli Roofing for a long time now, and so finally getting around to it. We had to re-do our roof quite a few years ago, and then had them come out several times for periodic recoating since then (and probably due for another). They are very responsive and communication is good. Costs seem to be in line with the market in general. We didn't have leaks beforehand and it doesn't leak now so all I can say about that is so far so good. We have recommended them to many of our neighbors and probably eight or 10 other houses nearby have used their services and everything I have heard has been very positive. Hopefully I don't need any roof repair in the future but if I do I would use them.

I had experienced water damage in my home during storm Ida in the fall of 2021. A roof leak was the culprit. Marcy and her team diagnosed the problem and delivered the needed repair all in a span of less than two weeks. Not only were they responsive, they kept to the promised schedule and communicated accordingly throughout the process. Their deliverable and the associated warranty is valued and is very much appreciated.Service: Roof repair

This company is most excellent to work with. I had a really bad roof leak and they gave me timing information when they could do it. They were on time and fixed my problem most expeditiously. They kept me informed on everything they did. There were no hidden costs or surprises. Almost two years later I did have a bit of a problem with a bad leak. They came right out and assessed the issue. The problem was immediately rectified. There have been no further issues since then. Marcy was wonderful to work with. Chances are you will have to leave a message but she is great at returning calls within a day or so. She does a terrific job of keeping you informed every step of the way. I am very happy with the work they did. The price was in keeping with my budget. Their pricing is a lot more reasonable than most of the contractors I spoke with. I highly recommend them!! I will definitely use them again if needed.

I have used Castelli Roofing several times over the years. The first time, they did some repairs on my previous house. The next time, they placed a new roof on my current home. They did the job right without any issues at a fair price. They showed up when they said they would (a rarity with Philly contractors) and didn't leave a mess behind. Professional operation. I will definitely use Castelli again should the need arise.
