    Had to have my roof replaced due to defective workmanship of another company 9 years ago. Tom not only did an awesome job fixing what the other contractor should have done originally but did it in a quick time frame. His pricing was fair and reasonable. It’s nice to know there are still companies out there that are honest and do quality work. I would highly recommend Jannace Roofing for anything related to roof repair and installation. You won’t regret your decision!

    As an attorney , I am held to the highest professional and ethical standards. As a roofer, Tom Jannace meets my profession’s standards. He is competent, trustworthy and equally important, he does what he promises. Weather permitting, he was always on time, always found the source of my roof problems and always left my business and residential premises neat and clean. His prices are reasonable and fair. Tom gets my highest rating.Ron Sickmen

    Tom Jannace and his son Nick were very honest, dependable and reliable for my roof installation. They fully explained what was going to be needed and how long the job would take, and were reasonably priced. They were able to provide the service in a fast, timely matter compared with other local companies. I am very happy with my new roof and gutters and downspouts. I would definitely recommend this company to anyone needing a roof or roof repair. The roof workers were very careful to clean up and take care of any surrounding areas. Tom came by several times to make sure that the job was to his satisfaction and that everything was cleaned up after the job. His company came highly recommended with great reviews and I can see why. I have no complaints only compliments on a job well done.

    My roof was damaged due to a storm and I needed an emergency repair done. Tom answered my call on a Saturday afternoon and shortly thereafter was at my house. He was prompt, polite and above all, professional. In addition, his price was more than reasonable. I highly recommend Tom and his team for all of your roofing needs. Thank you, Tom!
