About Our Company

T-J Roofing began operations in September of 1983, as a sole proprietorship owned by Tom and Sandi Swan. The company was sold to Mark and Diane Johnson on May 1, 2002. Mark had been Tom’s right hand man for 19 years.

We operate as a minority owned shop dealing in both the commercial and residential roofing markets.

We carry General Liability, Workers Compensation and Commercial Automobile Insurance with certificates available upon request.

We are licensed in the State of Michigan and The City of Toledo, Ohio. We are registered in all other North West Ohio communities where licensing is not required and obtain building permits as required so local building officials can inspect our work.


Choosing your shingle manufacturer, style and color is important, but choosing the right Roofing Contractor may be the most important roofing choice you need to consider.

Your roof is the primary “protector” of your home.  T-J Roofing will stand beside you throughout the Life Cycle of your roof.  T-J Roofing has been in business locally since 1983 and we will continue to be here as long as customers like you rely on us for that protection.  Your complete roofing satisfaction is our #1 priority, because our good reputation is what keeps us in business.

Safety at T-J Roofing is paramount and we pride ourselves on having continuous safety awareness.  A safe jobsite creates the setting for an above average finished product that will protect your home for years to come.  We value the safety of our customers and workers.

We will protect your home during the roofing process.  We will do everything we can to ensure nothing is damaged by us during the roofing process by covering landscape, decks, A/C units and other items that cannot be moved.  Roofing is a tough job and accidents can happen, that is why we take these extra steps.  If something is damaged by us, we will make necessary repairs and/or replacement. We are licensed and insured.

We will be with you long after the “sale” and will do all we can to answer all of your questions during this phase of the process.  There may be something that was forgotten or comes up along the way; we are always here to answer those questions.  Our workers, sales team and project managers continue their education by participating in online classes, manufacturer’s onsite training and T-J Roofing on the job training.  If we do not have an answer, we will research to find it.  The T-J Roofing management and office staff includes 3 roofers with a combined roofing experience of over 60 years.

As well as steep slope shingle roofs we also install a number of low slope roofing options. If you have a roof area where the slope is too low for shingles, T-J Roofing has an answer. We have installed reinforced PVC commercial roofing membranes for more than 36 years.  We also offer EPDM (Rubber) and modified bitumen membranes surfaced with colored ceramic granules to match your shingle color. 

Keep it cool.  Balanced ventilation will give your roof the longest life possible.  When vents are installed at the eaves and ridge of the roof, they provide continuous air circulation in the attic from the floor level to the top of the roof.  Moisture laden air then joins in with the air current flowing freely outdoors helping to prevent condensation and water damage.  While we are measuring, we will be calculating how much roof ventilation your home requires and present that to you with your proposal.

A great project should have a great warranty. We work with our manufacturers regularly to offer the most current warranties.  We offer warranties that are built into your roofing proposal.  We do all the homework and paperwork so that you can rest easy knowing if you have a problem, you are covered.  Most of our systems come with 40 to 50 year manufacturer’s warranty on material.  A 10 year workmanship warranty from T-J Roofing & Sheet Metal, LLC arrives in your mailbox shortly after installation is complete.  These warranties are transferable to new home buyers once in the first 10 years and that’s not a bad selling point if time comes to sell your beloved home.
