Recommended Customer Reviews
This is my second experience in a month with Cosmos Roofing. They recently did tar roofs on two homes next to mine. Cosmos is a terrible company for neighbors to deal with. They leave a smoking kettle in driveways overnight and it will fill your and your neighbors' homes with noxious tar fumes. They also blow whatever debris (foam insulation particles, old tar/adhesive, etc.) right off the roof into neighbors yards. When called or asked in person to stop both of these practices they ignore or aggressively argue with you. You and your neighbors will regret hiring this company. Cosmos do better.
We got our roof done from Cosmos a few years back. There was a leak in our ceiling during the last rains and I had reached out to Cosmos to have the roof checked. Its been over 6 months and no one has showed up to check our roof out.
They might do a good job installing the roof, but don't depend on them to fix any issues post-installation.
Cosmos was original installer of current roof, but it seems after the owner change, we've heard bad stories - installation issues, leaks, etc. Does not respond to current email or phone calls.
Alex and his team are true professionals. We used Cosmo's for a patching on our roof when we had the really bad rains at the beginning of the year. Then this summer we did a whole roof. The workers were efficient and friendly and got the job done in a timely manner. They always explained what was being done and cleaned up when they were finished. I have already referred them to two friends and will continue to do so.
Our composite roof was over 30 years old and needed replacing (no leaking). Quote was competitive with other bidders and I selected them because Tim who did the quote was very knowledgeable. The quote took a few days to arrive (re-roof 3000 square feed including garage, replace all gutters and add one downspout), but that was expected given that the wet winter pushed a lot of urgent jobs in front of ours.
Once the job could be scheduled (about 1 week ahead), It took just about a week to get it all done. The roof looks great (presidential shake) and the inspections were done with no comments.
After demolition, Tim did very careful work assessing the condition of the plywood and discussing whether to replace some that was borderline acceptable (so I opted to replace at $1000 additional cost). He also agreed to cut off and replace a section so I could replace an old bathroom fan. Communication during construction was good and the roofing was well supervised by Tim (with one helper), so I have confidence all the flashings are well done and sealed.
The cleanup was also very good with no debris left in the bushes around the perimeter.
Gilbert U.Review your customer service pamphlet and put someone else on the phone... Nothing accomplished...
Called several times to request a quote for a new roof. They never called back to schedule time to provide an estimate. Guess they are doing that well to turn away business. At least tell people up front you don't have time instead of simply telling them you will call back and won't.
This company are the most professional and responsive roofing companies in the area. I would highly recommend Cosmos roofing to anyone wishing to get a new roof or repairs.
The team are courteous, clean up after the job and turn up when promised. A five+ star on customer service
I had Alex and his team come out to do our roof about 11 years ago. First a little bit about that experience. I was trying to surprise my wife with a new roof while she was out of town and therefore the job needed to be done in 3 days. Cosmos' bid was reasonable, they answered all my questions and came out and completed the job within the tight timeline. My neighbor was a retired contractor and was impressed by the efficiency as well as the quality of the job. As I know nothing about roofing, having that 3rd party validation was huge for me. Since then I have recommended Cosmos to anyone that has a need for work on their roof.
Fast forward to today. Some the venting behind the gutters was falling down. I tried to repair it myself but was unsuccessful. I was curious if it was covered under my warranty and called Cosmos. Alex happened to be in the area and stopped by. I was surprised to learn that he remembered me as well as the job done by Jesus and his team. While he was clear that the venting had nothing to do with his team's work (and therefore not under warranty), he took time out of his day to climb up and repair the venting.
I continued to be impressed with the care and concern that Alex has for his customers (even former ones like me). Thank you to Alex and his team.
They were great finished on schedule & were clean. We're very satisfied and would highly recommend them for a tar & gravel roof replacement.
