Review for Diablo Roofing Services Diablo Roofing Services did a very good job on my roof project! The crew started on Monday, 7/28, and finished everything in just four days. The project included removing the old roof, installing a new Presidential Solaris roof, and putting in new gutters and water pipes. The team worked quickly but with great attention to detail, making sure to protect the bushes around the house. At the end of each day, they thoroughly cleaned up all debris so the yard never looked messy. Whenever I had a minor concern, the team responded right away and fixed it without hesitation. That kind of responsiveness made the whole process smooth and stress-free. Overall, I'm very happy with the results and grateful to the entire crew -- and especially Hector -- for their hard work. I truly appreciate the professionalism and dedication. The new roof looks amazing, and I hope it lasts well over 40 years! I've attached photos of the work in progress and the completed project. Thank you again, Diablo Roofing Services! read more

See all

Edith is awesome! I spoke with Edith on the phone and she was so nice -- super friendly, informative, and easy to talk to! She replies to emails lightning fast and actually calls back (which never happens anymore ). Seriously, she made the whole experience smooth and stress-free. Big shoutout to Edith for being amazing! read more

Great company, had a leaky roof and found Diablo Roofing Services They we're to be very professional and honest. Hector came, did an estimate and within a week the job was done completely w/o any problems. Will use them again for any roof repairs. read more

Excellent communication and scheduled a quick visit to generate an estimate. Work was ultimately scheduled and performed quickly. All workers I dealt with were professional and friendly. read more

Diablo Roofing and there staff, especially Hector, who did an amazing service on my roof, were top notch . Hector called me when he was on his way to my home. Not just on time but early! He told me everything he was going to do and did just that. Very professional and polite to the end of the job. Gave great advice on keeping my roof in order for the best results for long term life of the roof. I wholeheartedly recommend this company and will tell my friends and neighbors and family to use them. Thank you!!! read more

Rogelio did not perform work for us, my review is solely based on our interaction and experience with him. We had an issue with our roof's gutter system that was spilling over the gutters. We had multiple roofing contractors come out to look at it, so I don't remember the exact conversation with this professional. But from what I remember, he suggested to clean the gutters, valley, and 2 cracked tiles and a sliding tile. Verbal quote was $750 (important for the remaining of the review). At first, we wanted to hire him to help us with this project over the other professionals since he seemed trustworthy. We reached out to ask for a proposal in writing with the scope of work and he seemed to get irritated and his response was, "I will tell you guys multiple times, but if you guys are not comfortable, I understand and just find somebody else". All we wanted was to get the detailed work in writing so we are both protected (since everything was verbal beforehand). Having the detailed work in writing is a reasonable request especially since - On the cslb.ca.gov website, "In California, there must be a written contract for all home improvement projects over $500 in combined labor and materials costs. That contract must include specific information about your rights and responsibilities. In addition, any changes made to that contract must be in writing, be legible, be easy to understand, and inform you of your rights to cancel or rescind the contract. If you are promised something verbally, make sure that it is also included in writing." Since he was planning on fixing 3 of the tiles, I was going to ask if he is going to spot patch the decking if it is damaged. If not, what would he do to fix these 3 tiles? He completely ghosted before I had the chance to ask. Overall, he didn't want to provide anything in writing and didn't want to answer any questions other than "your issue is from lack of roof maintenance". I would proceed with caution if choosing to work with them on your projects as his response (and lack of willingness to provide a proposal or anything in writing) was a huge red flag for us since he got irritated when asked even though it is a California legal requirement for licensed contractors (especially work over $500). In general, didn't seem too friendly with getting our questions answered. As a real estate professional and homeowner who had my fair share of working with and communicating with many contractors and professionals, I haven't had an interaction like this with a licensed contractor before. read more

This contractor keeps deleting their page to dodge bad reviews. Hiring Diablo Roofing Services was the worst experience I have ever had with a contractor. They improperly installed the underpayment on my roof, voiding the manufacturer's warranty. The manufacturer calls for "plastic cap staples or nails," this contractor refused to use them. (see attached picture) They improperly installed my attic vents and tried to only install 4 when the contract called for 6. They had to tear off the roof they installed and redo all the work. All my gutters leak and I can't get them to call me back. DO NOT HIRE THIS CONTRACTOR! read more

Very easy to deal with and very fair for such a small project I had. Would definitely recommend and use again.

I have nothing but praise for Diablo Roofing Services! I asked for an estimate to remove my old shake roof, and replace it with composition shingles, and replace the old gutters- Rogelio came right out, and I had my estimate the next morning. Their prices were very competitive and each staff member was friendly and willing to answer any questions I had. They pulled the required permits, ordered the materials and completed the job in record time- they left my yard clean and neat at the end of each workday. When they had finished they made sure to tell me they stood by their work, and would come out ANYTIME if anything went wrong. I simply couldnt ask for a more pleasant experience and HIGHLY recommend you give them a call! read more

Great job on the roof. House is a rental property and the demo crew destroyed a few established shrubs and plants that belonged to the tenants. One understands that a plant or two may be damaged, but an established shrub (4x4x5) should still exist after work is done. When confronted about it, they expressed "it happens". Eventually they agreed to pay for 1/2 of plants destroyed value and we paid the other half. On a 26K job, it seemed absurd. Also they didn't come back to repair a gutter that they said they would repair. 4 stars on roof quality (would have been 5) 3 stars on customer service. read more

I called Rogelio to inspect my roof since I saw leak spots in my bedroom. He did inspect and discovered the problem. Unfortunately, the issue was under my solar panels and that company will have to be called. In the short time I dealt with him and his company, I could tell they were top of the line. Very trustworthy. I have passed on his information to several of my friends in they ever needed a roofing company. I would definitely recommend. read more

From the moment i noticed a leak in my roof to reaching out to Diablo Roofing Services i am more than pleased with their work. I ended up re-roofing my home and the crew was amazing and the results are fantastic...hands down a great company read more

This is a fantastic organization that have incredibly high standards for service and quality.

They were super quick and responsive to Yelp and emails and everyone I worked with was friendly and helpful.

I was able to get a same day estimate which was very reasonable. The repairs were done within a week. All employees I had contact with were friendly professional and polite. I look forward to using the for future roofing needs! read more

I was so lost and in need of a roof. I was told by a friend to call Diablo Roofing. I judged my friend at first for calling anyone with that name and I was very hesitant to contact them because of the name and well we are a God fearing home! But I prayed and called them. They were God sent! So helpful, knowledgeable, courteous, friendly, efficient and fast. They had a very respectful associate call me back with in 3 hours of my message, had my estimate by the following business day, pricing was very reasonable, and by the following week we had a new roof! I could not be happier and more pleased with the whole experience. I highly recommend Diablo (sorry Jesus) Roofing. read more

These guys did a great job. Rogelio came and did the estimate on my roof witch was a re due from a previous roofers job. The previous roofer left all kinds of leaks in my roof. So glad i checked it out before it was too late. I had a whole dispute with this company and ended up getting my money back Diablo roofing did great. They were very informative with all my questions and concerns as well as professional and fast. They were always in communication with me through the whole process from the city approval to the end weeks after the roof was already done. A very young company but I would say they are off to a very good start. read more

With the rain we have had this weekend, We had a gutter that needed to be fixed. I called the number and got connected to someone right away. He just so happened to be passing through my city so he stopped by and fixed our gutter within a few minutes. Very friendly, professional, super fast and reasonable pricing. I can't speak on if you need your roof repaired but I would definitely recommend Diablo Roofing. (We are lucky we found Diablo Roofing to be open and working on a Sunday!) read more

I had a really great experience working with Rogelio and his team. I was able to schedule work done for my roof quickly after getting a very reasonable estimate. Great job on a flat roof job! Would definitely use them again in the future! read more

They are price gouging, they charge double on what local or other roof services would charge. They don't even have a valid license and they charge double compare to someone that has license. I talk to one of them, it sounded like they can't even speak english. Take your business somewhere else, this is a rip off. read more

Great work on repairing a hole in our roof sheathing and installing new gutters. Prompt responses and showed up on time. Very happy with the work the team did. read more

Rogelio came to my property with his helper on a Saturday. It was an urgent fix and he was able to get it done. I have a tile roof and it's pretty hard to take it off, but they did a great job. They were reasonably priced and did a good job, Highly recommend them. read more

We were really tardy in getting some dysfunctional gutters fixed. We didn't know if it was a clog or a structural issue. Diablo Roofing came out and gave us a worst case scenario estimate that we'd have to remove all of the gutters. When the crew arrived, they realized the issue was partially a clog but also just a messed up design of the existing gutters. The crew did an on site pivot to do a much less expensive fix, instead of sticking to the more expensive replacement approach cutting the overall costs in half. Also, the Diablo Roofing team showed up on time both for the quote meeting and the day of the work. A great experience start to finish. read more

We had a leak on the ceiling early Saturday morning. Since it was raining the day before we thought the leaking came from the roof. The first company we called was closed for the weekend. Then we called Diablo Roofing Services and Rogelio picked up right away. He was at another job in Napa but agreed to come out to Concord to check our roof in about 1 1/2 hours. He showed up at the promised time and soon identified the leak was not from the roof. He suspected it was a plumbing issue and went on to check the attic directly above the leak. It was indeed from a broken pipe in the attic. He offered to shut off the water and referred someone he knows that does plumbing work. He was thorough, caring and efficient. Despite the trip out to our home on a Saturday, the time he spent checking/investigating which led to an accurate, prompt diagnosis of our problem, he didn't charge us anything! I couldn't be more grateful. Thank you kindly Rogelio. You are a gem in today's business world. We wish you the best! read more

They just finished installing our new roof. In two days, they removed the old tiles, installed plywood and a beautiful roof. Just showed us a video taken while on the roof so we could see all the improvements. What a team, all very professional. We were very pleased. read more
