How to Tell if Your Roof Needs Replacement
- Age: Your roof is nearing or has exceeded its lifespan.
- Leaks: Persistent leaks signal a compromised roof that needs replacement.
- Shingle issues: Curling, buckling, or missing shingles are signs of deterioration.
- Granule loss: Excessive granule loss from shingles indicates aging.
- Sagging roof: A visibly sagging roof is a structural concern.
- Energy inefficiency: An old roof can lead to higher energy costs due to poor insulation.
- Mold or moss growth: Mold, moss, or algae growth suggests moisture retention.
- Daylight through attic: If you see daylight through the attic, it’s a sign of roof deterioration.
- Damaged flashing: Cracked or damaged flashing can lead to water infiltration.

What to Expect During Roof Replacement
Our tried and true processes ensure transparency through every step of the roof replacement process. Our team is committed to quality workmanship, and a great experience from start to finish.
Contract
Following the roof inspection, your sales representative will provide you with a bid or estimate tailored to your roof’s specific measurements and materials you’ve selected, such as shingle type and color. This will serve as the contract for scope of work.
Scheduling
Once you’ve signed the contract, we will order all necessary materials and schedule a day for your project to start. Our friendly team will ensure the dates work for you.
Job Site Setup
Our professional crew will lay out tarps, prepare plywood, shingles, tools, and more outside. This protects your landscaping from damage, and allows us to efficiently get your roof replacement or repair completed. If you have any questions or concerns throughout the process, we request that you direct them to your main point of contact: the project manager or our office.
Tear-Off
The removal process can involve handling an average of 10,000 pounds of wood, tarps, nails, and insulation, which can be a dangerous process. We promptly dispose of these items in our dumpster. Our experienced team ensures that this process is as safe as possible. For your safety, we request that homeowners leave the task to us.
Removal of Old Wood
When we expose the original roof deck, we carefully evaluate its condition and provide recommendations regarding wood replacement. Fortunately, in most cases, homes only need minor quantities of wood replaced.
Completed Roof
Once our work is completed, we diligently clean any areas where we worked. We also inspect lawns and plantings to ensure that unwanted debris is removed. Our roofing team uses powerful magnets to pick up any nails, screws, and bits of wiring that might have fallen during the work. We haul everything away, leaving your home’s exterior pristine.

“Would use TMJ and recommend them again and again and again. We had a huge and unique project with our roof replacement and various other needs and TMJ took it on without hesitation, got creative, brought in as many people as it took, reached out and utilized other resources as needed, was very responsive, kind and helpful and did literally whatever it took to get the job done and done well! We were very impressed with the crews – they all did great work, cleaned up like nothing happened and were professional. Thank you to all the fantastic and skilled crews, to Curt, Mike and Josh and Makenzie!”
BRYAN F.
“I can’t say enough about how good our experience has been with TMJ Construction. They were prompt and complete with the bid and stuck to the timeline they gave us for installation. Their crew showed up early and took good care not to damage the landscaping around the house. The job went quick and their clean-up was excellent. The new roof looks great and we’re very pleased. Contractors who come through as they promise can be hard to find. TMJ delivers.”

“We had Mike from TMJ help us with an insurance claim. He was super helpful and easy to work with. They were able to replace our roof and siding way faster than I ever imagined and it looks amazing. I will use them again!”
