do not hire these people.they were paid in full and did not pay the supplier.now the supplier has a lien on my home. I owe them $5000 in supply fees. the attorney says I am one of many .they owe supplier a large sum of money read more

To call their communication horrible is an insult to horrible. They DO NOT answer their phone and hide behind and/or fail to clear voicemail. I had to go in person twice (once to reschedule a postponed site inspection and the second to get the estimate) only to be told they would not do the repairs. The roof is too steep (10/12) is the excuse. read more

Wonderful experience with Duncan Roof! They did a great job at a fair price. Techs are very knowledgeable. Would definitely recommend Duncan for a new roof or a roof repair. read more

I recently got a new roof from Duncan Roofs. The crew was very knowledgeable and courteous. They did not leave a mess and had the job done in 1 day. They offer a lifetime warranty and come out to do yearly inspections at no cost to the homeowner. I highly recommend Duncan Roofs for your new roof. read more

Duncan replaced the large flat roof on my property. If I had to do it again, I would call Duncan. The relief from worry over leaks with all this rain is wonderful. Thank you, Duncan. Irene D. read more

Courteous and professional team made a total roof replacement due to storm damage as least stressful as possible. Their commitment to excellence, not only with their roofing but with their communication was such a blessing as we recovered from horrible storm damage to our home. Highly recommend Duncan Roofs! read more

They installed a roof system that was not contracted and neither asked nor informed me about it until after it was complete. The rationale for switching was solid however the execution was a disaster. They called for payment before most people are even home from work -- I said I would wait until the inspection. I learned about this switcharoo from another contractor at my home. I'll say that again, my siding contractors told me how the roofing supervisor told THEM how they were installing the roof but didn't bother contacting the homeowner right inside. I reviewed installation instructions for the flat roof system they did install and realized they had done that roof incorrectly. Bob Duncan came to my house a few days later and said -- and I am literally quoting, not just paraphrasing, -- "I don't feel comfortable with this relationship".... we're going to remove the roof and then you can do what you want. I told him I would hold him to his contract. He said I wouldn't, I said I would. Then I said he's leaving because I realized they didn't perform the work properly and shame on them for leaving their customer in the lurch. This was scheduled WITH my siding guys at the same time because it required back and forth work between the two contractors. I'm now in the lurch with my siding being unable to be completed until the flat roof is installed and flashed so siding can go over roof flashing. After Bob Duncan left I tore off the top layer and sure enough, this 3 layer system only had 2 layers which were not properly flashed allowing water to seep in under top cap sheet. They didn't install cement flashing under the drip edge , didn't use cant strips at roof/wall connection, or do proper roof/wall flashing techniques. This is amateur work performed by people who clearly do not care about their reputation or their customers. Wait for the BBB reports, State of Florida licensing complaints, and social media smackdown, Bob Duncan. Find the video of their horrible workmanship at https://youtu.be/OHaEd_ks__4 read more

Not sure how exactly to rate Duncan Roofs. They came out to our house and did what they were contracted to do, put on a roof in 1 day. The laborers were professional and courteous and did a great job. The issue is one of the roofers fell through the roof, all the way through the ceiling. Thankfully he was okay and very apologetic. No biggie, main thing was he was okay. So our back office has a huge hole in the ceiling that looks up at the plywood on the roof. It is about 3 foot by 2 foot, pretty substantial. I didn't cause any fuss at the site because they were doing their job and i figured the adjustor or owner would square everything up for the damage caused inside our house. Now, i assumed that they would either fix the hole OR take money off the bill. I was fine with either. They did neither, i was basically told that the roof was bad and sorry about my luck. I replied the reason they were there was BECAUSE our roof was bad. They had a reputation as a good company and i expected they would have handled this with better customer service in mind. So for what could have been a fix that might have cost them $100 TOPS they have a customer that has spent a large amount of money with them that is less than enthused about their company and their service. The roof is great, the price is on the higher side but nothing outrageous. The customer service error in judgement knocks off a few stars. Could have been 5 star but sadly gets 3 stars. read more

My rental house needed a new roof and my property manager recommended three different roofing companies, of which Duncan Roofs was one. All three bids were comparable but I was especially impressed with the professionalism of the Duncan representative, Pat. I couldn't be happier with the result. The crew, all American, showed up on time, completely replaced the roof in one day and then left the area cleaner than it was when they got there. I am VERY impressed. They did everything they said they would do when they said they would do it, so when I needed to replace the roof on my residence (fun year for roofs), I had Duncan back out and they repeated their stellar performance. Bob White was also very pleasant to deal with and both efficient and effective on the job. It's not an accident that this company has been in business for almost 100 years. I highly recommend Duncan Roofs to anyone needing a new roof or repairs. read more

Code Enforcement came to my house saying I had two open permits for my roof that that I had 15 days to close them or I could be cited. I made numerous calls to the company and would not return my calls. It took code enforcement to finally get them to close the permits after more then a month. This was very stressful and I would never use this company again.. Be ware read more

I was disappointed to see the low ratings. I have had 2 roofs done by Duncan. Fair price and stand by the warranty and have had no problem with the occasional leak that have sprung over the many years. read more

Initially the work appeared satisfactory, however within one year our roof was leaking. Duncan's response to our request for warranty repairs was very lacking, we were told that they were quite busy and they could not get out to fix the problem for three months and that we should poke a hole in our ceiling to allow the water to drain and prevent the ceiling from coming down (good advice, however a very inadequate response time) eventually they made it out to repair the roof, which took three attempts as the roof continued to leak over the next two years, eventually they found the problem spot and repaired it. This past year we developed another, much more serious leak in a different location. I attempted to call Duncan to repair the leak and they did not return my first two phone calls to them, so I contacted another contractor for an estimate to the repair the roof, who promptly returned my call and where on site for the estimate the next day. Their estimator said that my roof looked like it was 40 years old and that I likely had defective shingles, the leak could not be repaired short of a complete re-roof. After this I attempted to contact Duncan again since it appeared that I had to make use of the manufactures warranty, this time they actually answered the phone and scheduled someone to come out for the "repair", their repair tech had the same opinion that the shingles were defective and the roof needs to be replaced. He told me that someone would call me the next day to schedule an estimator and to prepare the warranty package. Shingles need to be removed, photos taken and other paperwork that needs to be sent to manufacture. They did send someone out to remove sample shingles and take the photographs, however I am not sure if they ever sent them to the manufacture. A month later I contacted Atlas (the manufacture) they stated that they had not received the warranty package and that I should get a tracking number. I contacted Duncan again since they never sent anyone out to prepare the estimate and to get the tracking number. They provided me with an estimate and sent someone out to once again remove shingles and take pictures for the warranty package. I was told that this was to be sent out certified mail. A month after that the manufacture stated that they have not received the warranty package. I have been getting nothing but excuses and postponements from Duncan for the past month and a half of attempting to get the tracking number to provide the manufacture so they can get started on their review of the shingles which will take 45 business days Meanwhile my roof is still leaking and all I hear from Duncan is "were sorry we are unable to take your call at the moment..." If you want the worst possible customer service possible and a defective product use Duncan Roofs. If you want repeated leaks for over ten years use Duncan Roofs. If you want to have to re-roof your 30 year roof after 11 years costing you thousands use Duncan Roofs If you want to listen to an answering machine call Duncan Roofs. If you want your roof repaired right... go somewhere else. read more

DUNCAN ROOFING IS THE WORST. They worked on my nextdoor neighbors roof. I made sure to ask the workers if it was safe for me to park in my usual parking spot - which is in my driveway but we share an alley. The workers assured me parking there would be NO PROBLEM at all. On my lunch break at work the next day, my tire clearly had a nail in it. Took it to Bob Lees on 4th (love them) and he said they will patch it and I'll be good to go. They were unable to patch it, i needed a whole new tire - and he saved the roofing nail for me. I have been told by multiple experts that you should never replace one tire at a time, so I decided to just replace all 4 to be safe. I also had to take a $15 x2 uber there and back to my work. I had to take time off work to go pick up my car. You can see how this ordeal is starting to add up for me. When I called the roofing company I was extremely respectful and understanding that mistakes happen and I would appreciate a resolution. I kept being told I would get a call back and didn't hear from the owner for 4 days. The girl on the phone told me this happens to them all the time. In the meantime, one of their workers who was significantly older than me HIT ON ME in front of all of his coworkers at 7AM in the morning. I'm a 29 year old woman that lives alone and this guy obviously knows where i live. How uncomfortable and so unprofessional! Every morning I had to deal with them all gawking at me. When the owner finally called me back - he was so rude to me I couldn't believe it! I was so calm and understanding up to this point. He told me that there was no way the roofing nail was from him. Omg! It's literally my next door neighbors roof. He said he would only pay for the cost of a used tire. I would never ask them to pay for all 4 because that was my choice- but cmon you're not going to offer to pay for even the full cost of 1 or 2? He didn't even apologize and he was talking to me like i made the story up or i was lying. I didn't ask for him to pay for the Ubers or the time off work. If this happens to them all the time, like his office manager said, maybe they should include that MISC expense in their estimates. I am baffled that a business owner treats people this way - he was so disrespectful to me. This guy does not deserve your roofing business. read more

Horrible experience with Duncan roofs. I strongly recommend against using Duncan roofs. Workmanship is horrendous. They got tar everywhere! All over my driveway, sidewalks, pool deck, backyard deck, one of my garden hoses and my A/C unit! Of course they said they would take care of it, but two months later and it's still everywhere. Now insurance is taking care of it. The fascia boards they replaced are now coming loose and are warped. Two months later! I am still trying to get them to replace a drip shield they installed dented and bent. Worse yet, they caused severe damage to my driveway. For the first four weeks after completing the roof, they said they would take care of all the damages. For the next four weeks, they shifted blame to the delivery company (whom I didn't hire or sign a contract with). Now they claim they are not responsible and that the damage was prior to their work. However, I have a picture of their huge truck parked where the damage is. If it was cracked before, would they have parked their multi-ton truck on it? read more

I had Duncan roofing put a new roof on my house several years ago. I was happy with the work until a storm. Hurricane Irma hit and I had leaking inside the house from the roof. They sent someone out to do the repairs which they said were the result of incorrect sealing around the joints. I understand that a hurricane hit and the wait of a month to do the repairs is understandable. Since then I have called 6 times and emailed 6 times without the courtesy of a response. The inside of my house was damaged due to the roof and they will never respond. Apparently Mr Duncan is always unavailable and or on vacation so he cannot be reached. Tiffany is the receptionist and she never responds or passes along the information. read more

Beware of their crews driving through Pinellas County. One such crew in a truck with a trailer just ran a red light by Clearwater High School; cutting me off. Then a couple workers in the trailer proceeded to yell things & make gestures toward me regarding my driving. Last I checked green lights meant you had the right of way. Very unprofessional. read more

Duncan Roofs, great roof installation, terrible warrantee follow up work. We had our roof replaced 2 years ago, good job. Had a leak in the roof Oct 2016 that damaged the kitchen ceiling. We had to wait until early Nov. just to get someone to come to the house. The repair of the roof didn't happen until Nov.28th. the stain and damage in the kitchen, wasn't even addressed. We had to wait until Dec 19th for some one to look at the kitchen. He brought a gallon of bleach and a ladder. He told me that Mr. Duncan sends a worker out with bleach first before they are willing to send out a professional Painter/ Repairman, even though they knew that there was damage to the ceiling as well as a water stain. We are still waiting for a follow up call from the company. I will update the review, if and or when the warrantee work is completed. read more

My wife and I hired Duncan Roofs to make a minor repair to the roof of a rental home that we own at 1742 22nd Ave, St. Petersburg, FL. During the repair, an employee of Duncan Roofs knocked over a ladder and damaged the fence on the property. I immediately called the company and left a message describing the damage and asking for a return call. I also sent an email request a call back. I have not received a call or email and the fence has not been fixed. read more

I called Duncan Roofs a month ago to have someone come out because I had what appeared to be a roof leak.. Since it seemed small and the first appointment they had was a month later I hesitantly agreed. A day before the appointment they called and said could they move my appointment one hour later. I told them I had to leave by 10:30 (BTW first appointment was 8:30 that I agreed to change to 9:30 for their convenience not mine) The lady said no problem. He will be there and gone. She said nothing about a one hour window. As a matter of fact they never once mentioned that. Now I cannot stay and the lady on the phone did not care one bit. Customer service 0! I would tell you they do good roofing, but I have no idea. If you want to have a roof put on or want a repair forget it if you are in any kind of hurry or want feel important, because you are not. read more
