Roof flashing is an important part of your roof, but most people only notice it when it fails. This is a thin metal that saves chimneys, skylights, roof valleys, and vents from water. If it gets old or comes loose, water can leak into your home. In Minnesota, heavy snow, freezing and thawing, and strong storms can make failing roof flashing happen faster. You need to know the signs to avoid expensive water damage and repairs.
Why Roof Flashing Fails
Roof flashing can fail for several reasons. In many homes across Minnesota and Wisconsin, the primary cause is weather. Constant exposure to rain, ice, and snow leads to metal expansion and contraction. Over time, this weakens the seals.
Flashing may fail due to a number of reasons:
- Poor installation: It will not last long unless it is installed in a proper manner and with the right materials.
- Rust: When metal, such as steel or aluminum, becomes wet, it can rust.
- Roof movement: When the roof shifts, the flashing can pull apart.
- Old sealant: The glue or caulk that holds flashing can dry out and crack.
Commercial roofs with large surface areas and flat roofing systems also face flashing problems from standing water and UV exposure.
What Are the Most Common Signs of Failing Roof Flashing?
Failing roof flashing can look like other roofing problems. This makes it tricky to spot. There are some easy signs to watch for.
One of the first is water stains on your walls or ceiling. If you see brown marks on ceilings or walls, the flashing around chimneys or valleys may be letting water in. Another warning is dripping in the attic during rain. This usually means the flashing has gaps or cracks.
You might also notice damaged shingles near flashing. Shingles near the flashing that start to curl, crack, or break are a clear sign that something is wrong.
Sometimes you can easily notice the issue, like rust or cracks in the flashing itself. If the metal looks corroded or broken, it’s no longer keeping water out. On flat or low-slope roofs, water can pool when flashing fails. Over time, that water seeps under the roof and causes leaks.
You may think these problems are small, but do you know they can quickly cause rotting wood, mold growth, and serious structural damage?
When Should I Call a Professional to Repair or Replace Flashing?
In Minnesota, winter storms can turn a small leak into a big problem fast. A local roofer like Superior Roofing Company can inspect your roof and let you know if you need minor repairs or a full roof replacement. We also use the right materials for Minnesota’s weather and follow local building codes. If your flashing is more than 15 years old, or if you are already getting a new roof, it is smart to replace the flashing at the same time.
Call a roofing contractor Duluth MN as soon as you see any of these warning signs. You might try to fix failing roof flashing by yourself, but such leaks return without proper repair.
How Can I Temporarily Fix Damaged Flashing Myself?
Sometimes homeowners try quick fixes to hold off leaks until a roofer can come by. These quick fixes can help for now, but they won’t last.
Roofing cement can be used to fill in small cracks or gaps. It works like a patch to keep water out. There is also roofing tape, which is handy for covering small holes in the flashing. Or you might grab some caulk and seal the joints around skylights or vents.
The thing to remember is that these fixes won’t last, especially through Minnesota winters. They are just temporary. To fully fix the problem, you need a professional like Superior Roofing Company to repair or replace the flashing.
