MI Homesiding & Roofing
Most roof leaks in Knoxville come from bad flashing — not the shingles.
At MI Homesiding & Roofing, I’ve repaired many roofs that were recently installed but already leaking. In most cases, the problem is not the roofing material. It’s the flashing around chimneys, walls, and roof penetrations that was installed incorrectly or missing completely.
If your roof is leaking, there’s a high chance the issue is coming from flashing failure. I focus on finding the real source of the problem and fixing it the right way so it doesn’t come back.
Roof flashing is the material installed in critical areas of your roof to keep water out. These areas include chimneys, wall connections, roof valleys, and vents.
In Knoxville, flashing failure is one of the most common causes of roof leaks. This is not because flashing wears out quickly, but because it is often installed wrong from the beginning.
I’ve seen many homes where:
- there is no flashing behind siding
- chimney flashing is not sealed properly
- step flashing is missing
- metal flashing is loose or poorly nailed
These mistakes allow water to get behind the roof system and into the structure of the home.
Flashing problems are not always obvious at first. Water can travel before it becomes visible inside your home.
Common signs include:
- leaks after heavy rain
- water stains on ceilings or walls
- leaks around chimneys
- water coming in near windows or wall lines
- recurring leaks that were “repaired” before
If you notice any of these issues, the problem is often not the shingles — it’s the flashing system.
Most of the repairs I do are not simple wear and tear. They are problems caused by poor installation.
Some of the most common issues I fix include:
Missing flashing behind siding
Water gets behind the wall because no proper barrier was installed where the roof meets the siding.
Bad chimney flashing
This is one of the biggest problems I see. Many chimneys are sealed incorrectly, allowing water to enter around the base.
No step flashing
Instead of installing step flashing correctly, some contractors try to seal everything with caulk, which fails quickly.
Loose or rusted flashing
Metal flashing that is not secured properly will shift over time and create openings for water.
Improper sealing
Using the wrong materials or skipping critical sealing steps leads to long-term leaks.
Chimney Flashing Repair (High Leak Area)
Chimneys are one of the most common places where roofs leak.
I’ve repaired many homes in Knoxville where the shingles were new, but water was still coming in because the chimney flashing was done incorrectly.
If your leak is coming from around your chimney, this is not something that should be patched temporarily. It needs to be rebuilt correctly.

Roof Leaks Caused by Flashing Failure
One of the biggest mistakes homeowners make is assuming the leak is directly above the water stain.
In reality, water can travel through the roof structure before it becomes visible inside the home.
Flashing failure allows water to enter at critical points and spread into:
- attic insulation
- wall cavities
- ceiling drywall
If your roof is leaking, it’s important to identify the exact source of the problem.

Our Roof Flashing Repair Process
When I inspect a roof, I don’t just look at the surface. I focus on the areas where most contractors make mistakes.
My process includes:
Full inspection
I check chimneys, walls, vents, and all roof transitions.
Identify the real problem
Not just where the water shows, but where it enters.
Remove incorrect or damaged flashing
I take out what was done wrong to avoid future issues.
Install proper flashing system
This includes step flashing, counter flashing, and correct sealing.
Final sealing and protection
Everything is secured and sealed to handle Tennessee weather conditions.
Flashing is one of the most important parts of a roof, but also the most ignored.
Many contractors:
- rush the installation
- skip critical steps
- don’t install flashing behind siding
- use shortcuts instead of proper systems
I’ve repaired many roofs where the shingles were new, but the flashing was done wrong, causing leaks within a short time.
This is why I focus on details. If flashing is done right, the roof performs the way it should.
