Had a large sized tree fall on the back of my home that damaged the roof and severely damaged the back attic truss and broke the ceiling of a room under the truss. I called Greg and described what happened and he was at my home in less than two hours. Greg and Jose assessed the damage and Greg rescheduled some work he had Jose and his crew on and they started repairing the roof, truss and ceiling the next day. Greg got the shingles perfectly matched up that needed replacing as well as the aluminum siding facia that the tree ripped off the house. The repairs made look great and the truss was repaired and extra bracing was added to make it stronger than the original. I highly recommend Greg and his talented work crews for any roofing and siding upgrades or repairs you need. Greg went above and beyond to make my emergency go away quickly because he cares and that is a human factor you find missing in many contractors today. -
Dennis Home Improvement repaired/replaced our roof. The service and attention was top notch, everything was performed on-time. Prior to repairs the attentiveness to work with our insurance and perform the necessary inspections was smooth and we would recommend this outfit to anyone.
Their work was not only well done but they cleaned up everything, and hauled away all debris in a timely manner. Seeing the owner himself on your work was refreshing.
Very Professional - Thanks Guys
They installed a new roof 1800 sq ft home. Did a phenomenal job! Good communication, competitive pricing,showed up on time, and got my house done in one day. Jeff and Adam were present ready to answer questions and the roofers worked tirelessly from 6am-5:45pm. They are Rockstars! My roof is gorgeous so happy. Thank you Dennis Home Improvement.
My project required replacement of shingles and leveling of low spots on the roof on my house, shop and storage building. I was provided a detailed proposal including proof of insurance documents. The work was performed on time, on schedule and on proposal price. The workers were very professional and did a great job. I'm very pleased with the appearance of the new shingles. Communication was great. I was given updates before and during the project to advise me of the project status and progress. Dennis did a great job and I highly recommend them.
Gregg Dennis is a man of his word. Exceptional work ethic. Punctuational every appointment and every day and so is his work crews. His crews are the most polite and respectful I have met in this business. In a world where people don't keep their word or follow thru it is rare to see a construction company so truthful and work so hard to meet your needs and not disappoint you!!! This was our second big job with Gregg and already have another on the books , he also has done work for my family. Good Christian Man!! I appreciated all his and his crews work and look forward to our next project!!!
We contacted Greg Dennis to replace our 20 year old-deck/ pergola with composite materials. We couldn't have been more pleased with the results and the process! Gregg was easy to work with and always returned calls promptly. All his crew members were pleasant. They started early in the morning and worked until dusk...and they worked!!! The entire process took only 6 days from demolition to "rocker ready." This has been the most pleasant construction project we have ever had. I highly recommend Dennis Home Improvement!
I have enjoyed working with Greg and his team. He is knowledgeable of his craft, does good quality work, and a honest guy. He has replaced a roof for me in the past and came out to repair a different roof that had issues. He is patient and straight forward about the job and what is needed to be done to repair the issue. It has been a pleasure working with him and his team. Thanks for all the help!
What Our Clients Say
- Greg,
You have repeatedly said you want me to be happy. I have thought about that statement. Compared to you I know nothing about roofing. I do know enough to trust and respect you. I trust your extensive knowledge about roofing. I trust you with my house. As such it is ultimately you that has to be satisfied with my roofing job. If you are happy that it has been done right: I can be no less than happy as well in that judgement.
Thank you for your honesty and sense of responsibility, these traits (unfortunately) are rare qualities in todays world.
God Bless... Bill Pawley View the actual letter - Dear Greg,
I want to thank you for your help yesterday concerning the mold in the closet. With Gene gone, this old woman doesn't know what to do when something goes wrong with the house. I'm going to the paint store this afternoon and see if they have paint that will take care of the problem. I'm sure everything will work out.
Please forgive me for bothering you when you were so busy. You're a good, honest business man that I trust. I didn't know who else would advise me.
Many, many thanks. God bless you.
Sincerely, Elizabeth W. Wessel View the actual letter - Dear Greg,
We are writing to express our gratitude for the extra attention you gave to our roofing project.
It was such a pleasure to do business with a professional group of workers. Your company went above and beyond to see that every aspect of the job was completed to perfection.
If you ever need a reference for your work, please do not hesitate to recommend us.
Sincerely, Frank and Linda Branham - Excellent performance. Punctual and respectful crew. Greg Dennis is the most responsive contractor with whom I have worked.
