Roof flashing is a piece of metal that is used to seal junction points and around penetrations on your roof. It is most commonly seen around chimneys, skylights, and vents. Unfortunately, flashing on homes around Middle Township, such as Green Creek, Cape May Court House, and Goshen, often end up with roof flashing failures caused by year-round moisture exposure. If you’re a homeowner in Middle Township, learning about roof flashing failure and how to prevent it from happening can save you time and resources later. Here’s everything you’ll need to know, including who to call if you do wind up with flashing trouble.
Key Takeaways
- Homes in Middle Township near wetlands face higher moisture exposure, which accelerates flashing deterioration.
- Wind-driven rain, humidity, and salt in the air weaken flashing around chimneys, valleys, vents, and dormers.
- Flashing failures often lead to hidden leaks, attic moisture, mold growth, and roof decking damage.
- Seasonal spring and fall inspections help catch loose, rusted, or improperly sealed flashing before storms arrive.
- Upgrading to corrosion-resistant flashing materials helps protect Middle Township homes long-term.
Why Do Homes in Middle Township Have a Higher Risk of Roof Flashing Failures?
You may be wondering why flashing is more susceptible to failure in areas with higher level of moisture. Fasteners and hardware used to attach flashing to the roof can rust due to humidity and salt. Next, throughout the year, storms occur along the South Jersey coastline. Coastal storms and nor’easters produce strong winds that push rain sideways, striking flashing where it may be lifting from the wind or improperly sealed. Even several miles inland, salt-laden air accelerates metal oxidation and eats away at protective coatings, further damaging your flashing.
In short, your location creates a trifecta of conditions that counteract your roof’s flashing.
What Causes Roof Flashing Failures in Wetland-Adjacent Homes?
For many residents of Middle Township, Cape May County, your home is adjacent to some kind of body of water, whether that’s the Delaware Bay, Atlantic Ocean, or the wetlands in between. As mentioned earlier, moisture is a huge offender when it comes to what’s damaging your flashing.
Here are a couple of other causes of roof flashing failures:
- Corrosion: Rust can develop on chimneys, valleys, flashing, and roof-to-wall intersections.
- Deteriorated sealant: UV damage, freeze-thaw cycles, and moisture causes cracks to form and separate seals and caulking.
- Loose or lifted flashing: Strong winds cause uplift, dislodging nails and warping flashing.
- Installation errors: Improper overlap, incorrect fastening, missing kick-outs, or relying only on caulk instead of mechanical fastening.
- Animal intrusion: Birds, raccoons, and squirrels nest in wetlands and can lift or pry flashing edges.
Types of Flashing Most Affected in Middle Township, New Jersey
Some flashing is more vulnerable than others. Here is a look at the sections most liable to become a roof flashing failure:
- Chimney flashing: Multiple seams and heavy exposure to wind and rain lead to accelerated wear and tear.
- Valley flashing: A region that collects high volumes of water and debris.
- Step flashing: Vulnerable to rust and water intrusion when caulking fails.
- Vent pipe flashing and boot seals: Rubber boots degrade more quickly in humid environments.
- Skylight flashing: Frames exposed to moisture tend to see more condensation build up.
What are the Warning Signs of Roof Flashing Failure?
Knowing the signs that you’re headed towards roof flashing failure gives you an advantage. You’ll be able to detect or spot where the flashing is having an issue and also be able to call a roofing contractor in Middle Township before the problem gets out of control. That not only saves you time, it saves you money, because the more extensive the damage, the more expensive it becomes.
Here’s what to look for when your flashing may be failing:
- Rust streaks or corrosion around roof penetrations.
- Water stains on the ceiling near chimneys, exterior walls, and bathrooms.
- Damp attic insulation.
- Mold growth near vent pipes or valleys.
- Visible gaps where flashing should be sealed.
- Curling shingles near flashing, indicating trapped moisture.
- Dripping or bubbling paint on interior drywall.
Preventing Roof Flashing Failures with Maintenance
Routine maintenance goes a long way in preventing many roofing issues caused by prolonged moisture exposure. So what can you do to keep your flashing functional? The first recommended step is to schedule seasonal roof inspections during the spring and fall with a trusted roofing contractor like RGB Construction. A trained eye can spot corrosion, loose edges, and failed sealant before summer storms hit. Next, consider upgrading to corrosion-resistant flashing. Newer materials, like aluminum, coated steel, and copper boost longevity.
It’s also recommended to check and update your attic insulation if any condensation is found. By reducing moisture getting trapped in insulation, you can delay roof flashing failures.
See any debris trapped in your roof valleys? Remove it. Lastly, ensure your flashing is properly installed. Check for an overlap, the proper fasteners and kick-out flashing where required. A trusted roofer can help you verify that your current flashing is up to modern standards.
