After realizing I had a roof leak after a severe rain storm, I called Sebastian and they scheduled an estimate the next weekday. They explained what was / might be reason, how long it would take, & were honest about cost. They worked around my schedule and completed the work in a timely manner - only took about 1/2 day.

4 estimates. 3 local contractors & 1 big box store. Big box outrageously high. Sebastian was slightly higher of the 3 but offered much more in quality of product & service & warranty. A no-brainer.

Very prompt response to request for estimate. Work completed less than 1 week after estimate and within promised timeframe. Work seems to be of high quality and similar to other estimates I received. After i contracted for the work, I would have liked a little more communication concerning the actual date and time of their arrival. Otherwise, I was very pleased with all aspects of the job and would definitely recommend them.

Project Manager arrived on time for the estimate. He provided a clear and concise written estimate with no hard sell pressure. Price was reasonable and competitive. On the scheduled installation date, the crew arrived on time (7:30 am). they were professional and courteous making sure my property was well protected from any falling debris. The quality of work was exceptional. they completed the job by 1:30. After completion you would never have even known they had been here. Their cleanup of the properly was also exceptional. I was a little surprised when I received the invoice as I had not been told exactly how many sheets of plywood were used. this is the one item that I would recommend the crew foreman do a better job of communicating during the job in order to avoid billing surprises. However, when I called the office the owner explained the process to me in detail and even offered to extend payment terms for the unexpected amount. Darren and Stephanie have been very responsive to any and all of my questions regarding this project. Their knowledge has been invaluable and I recommend them highly. I will certainly call them again for my next home improvement project.

Said they would arrive by 7:30, got here at 7am. Roofs off within an hour and completely done with job by 1:30pm. Only signs of them being here are new roof and sign in front yard, other than that completely cleaned up, no left over nails, or scraps of materials. They did their best to keep from destroying any trees, grass, or other landscaping. Only had to cut off a few branches to get pallet of shingles onto roof. Used plywood on areas of grass that might be destroyed by trucks or people. Offered a variety of options based on any future work done to siding and gutters. Very happy and will be using again soon for siding and gutters.

Very professional work. Showed up at 7:30am and was finished entire job and cleaned up by 6pm. Laid tarp in family room to protect from debris when skylights were removed. Most important was when I was given the estimate I was told that the skylights had to be replaced because the roof warranty would not be valid if they just flashed around the old ones. I called manufacturer of shingles and they confirmed this. None of the other roofers I got estimates from said this even when I asked if skylights should be replaced. They said it was no problem to just flash around them. Skylights added another $1,000 to the job but they were already 18 years old and I appreciated being told up front to replace them?
Description of Work: Removed old roof and installed new one (on house and shed), replaced skylights, installed additional gutters to comply with warrenty.

Rescued me from the improper roof work done by another roofer. Previous roofer did not honor his warranty, although he'd promised to return and correct the faulty workmanship. Sebastian Builders corrected the problem. Spoke knowledgeably, professionally, explained findings. On work day, completed the correction with no fuss--quite different from original roofer.
