 Leaking Roof?  Maybe it's Improper Chimney Flashing!
(Home Inspections Norristown)

 

Have a leaking roof?  Often times, that roof leak has nothing to do with the shingles and something to do with improper chimney flashing

Chimney flashing is used to prevent roof leaks between where the chimney and the roof meet.

Chimney flashing leaks can happen for a number of reasons.

 

One reason is the chimney is not directly attached to the house frame and if the home settles, the flashing can pull away.

 

Another reason depends on the type of metal used for chimney flashing. That metal can corrode and rust over time and create a leak. 

 

Another big reason for chimney flashing leaks that I see all the time in home inspections around Norristown, PA is improper chimney flashing.

Just last week, I was hired for a home inspection in Norristown and came across a chimney that had improper flashing.

The chimney was missing counter and step flashing.

 

From the picture to the left, you can see someone surrounded the chimney with roofing mastic instead.

Proper chimney flashing, as shown in the illustration to the right from Carlon, Dunlap & Associates has step and counter flashing

 

Step flashing is installed with the roof shingles and is weaved between the shingles. 

 

Counter flashing protects against water getting behind the top edge of step flashing, preventing it from seeping down the chimney or other vertical surface.  It is installed after the shingles are installed and is cut into the chimney and installed on top of the step flashing

It is a relatively easy repair for a qualified roofer.

 

So, if you have a leaking roof, make sure to check for failed or improper chimney flashing!

David,  Great information, especially for the fixer-upper that thinks a little mastic is all that is required.

I see these bandaids all the time.  At least the buyer knows what they are getting into and can have this addressed before it becomes a bigger problem.

Linda- we had a similar issue with a rental home we bought.  Once the furnace went, we put in a direct vent furnace and had the chimney capped... took care of the issue!

Eileen- True- Not something a condo owner in NYC has to worry about!

Great information, David - I'll bet many of those mysterious "roof" leaks are really chimney flashing - I wish I'd had this information when our cottage was leaking!
