If you’re a homeowner in Myrtle Beach wondering whether your roof’s flashing needs to be replaced, or how much it will cost, you’re not alone.
Roof flashing is an essential element to making sure your roof is protected from leaks. And in Myrtle Beach, we often see heavy rain storms that can easily turn into a roof leak if your roof is not properly flashed.
Throughout the years, we’ve noticed that homeowners are particularly curious about the cost of roof flashing. This is because it can be expensive depending on how many areas of your roof need flashing.
Here we’ll go over what roof flashing is, how much it costs, and how to know you need roof flashing on your home.
Let’s talk about it.
What is Roof Flashing?
Roof flashing is designed to prevent water from intruding on your home in some of the most vulnerable areas of your roof. It is typically made of aluminum, galvinized steel, or copper and installed where vertical penetrations meet your roof. These areas include siding, chimneys, dormers, and walls.
There are a few different applications of roof flashing depending on the unique needs of your home.
These include:
- Step Flashing: Used along roof-to-wall connections like dormers
- Headwall Flashing: Placed at the base of a vertical wall meeting the roof
- Counter Flashing: Commonly used with brick siding, inserted into a groove cut into the masonry to shield underlying step flashing.
Most flashing is hidden beneath shingles or siding, protected from the elements. Because of this, roof flashing can typically last many years.
How Long Does Roof Flashing Last?
Depending on the material you choose, roof flashing can last:
|
Aluminum Flashing |
15-30 years |
|
Galvanized Steel Roof Flashing |
20-25 years |
|
Copper Roof Flashing |
Can last 50 years if installed properly |
However, there are a few signs you may notice that can indicate it’s time to have your roof flashing replaced.
These include:
- Visible rust or corrosion
- Leaks or water stains near roof-to-wall connections or chimneys
- Brittle or cracked siding near flashing points
- Ongoing issues flagged during multiple roof replacements
If you’ve noticed any of these issues, you may be curious: “How much will it cost to have my roof flashing replaced?”
How Much Does Roof Flashing Cost?
The cost to reflash depends on the area of the roof and the type of siding it’s paired with.
Here's a general overview:
|
Roof Area |
Estimated Cost Range (During a Roof Replacement) |
|
Average Sized Chimney |
$250 to $600 |
|
Dormer |
$300 to $700 |
These prices reflect the cost including labor. Usually roof flashing is least expensive to install when you have vinyl siding. Hardy board and cedar siding are more fragile, making the flashing replacement more labor-intensive which can increase the cost.
Often homeowners look into roof flashing when they’ve had a home inspection.
Did a Home Inspector Tell You to Replace Your Roof Flashing?
It’s incredibly common for home inspectors to tell homeowners that they need their roof flashing replaced. And while it is true some of the time, we’ve noticed that this can add unnecessary stress to sellers. Particularly because it is not always the case. Before you have roof flashing replaced on your home, be sure to have an inspection from a roofing expert.
Do You Need Your Roof Flashing Replaced?
Roof flashing can be an expensive endeavor. So it’s important to know the cost to have it replaced if you feel it’s time.
Now that you know how much roof flashing costs, you should also look for any signs that your roof flashing may be failing or compromised. And if you’re not sure what to do, you should call a roofer you trust to complete a thorough roof inspection. Be sure to get photos from your roofer so you can see any damage you may have to your roof flashing.
