Hi. My name is Ken and I'm from rooftwins.com. I'm at a homeowner's house here in Manassas,
Virginia and the homeowner is complaining about a roof repair that she needs done around
the leaking chimney. After we did a full inspection of the entire roof, we noticed that there
are many different areas on this roof that need to be addressed
that's a problem.
The first area that I'd like to talk to you about is the area where she's having the leak.
She's having the leak on the sides of the chimney, completely around both sides. So,
in order for us to correct this problem, we need to remove the shingles, go down to the
bare wood, install ice and water shield to the wood surface, remove the siding, have
the ice and water shield go in behind the siding. Then, install
step flashing completely around the entire perimeter.
Once the step flashing is in position, we can then put the siding back into position
and then re-shingle around the entire perimeter of the chimney and that will take care of
that problem. But then you have all these other areas that are causing a problem, and
these two areas can cause the chimney to leak as well.
As you can see, the flashing is exposed on the outside and it's nailed down. That will
cause leakage to the chimney area. The shingles should've been overlapping the sides and they
should not have nails penetrating through the middle of the flashing. So what we need
to do is remove the shingles around all these penetrations here because they all have nails
going through the flashing, through the attic fan, through the two stack pipes, and the
two roof vents also have nails going through the flashing.

So, once we have all the shingles removed around all the penetrations, we can then repair
the flashing, then re-shingle around all of the penetrations except for the two roof vents.
Those two roof vents are very cheap. So what we'll do is replace them, fasten them into
position, making sure that the nail heads are holding the flashing down and not putting
nails into the middle of the flashing.
Once they're in position, we can then re-shingle around all penetrations. As a precautionary
measure because this can also cause leakage, you have the weather collar on the two stack
pipes. If these collars are not sealed well, water will bypass the collar, go inside the
flashing, cause leakage all the way down to the basement near the furnace, and we have
to seal around those collars with Geocel Tripolymer
sealant.
Once all these problems are taken care of, this homeowner in Manassas will never have
to worry about having roof repair work down for many, many years to come.
