NEW construction home has no flashing on chimney?

Anne Byun
by Anne Byun
moved into home a year ago and now we have a leak in a room (which is near the chimney line). Our builder's defense was that there's "internal flashing". But from what I've researched, there's no such thing. I also have 4 exposed nails in the shingles which could also be source of the leak. My question is - is this bad workmanship? Negligence? I also have a deep "valley" in the rear of the chimney which you can see in the second photo. Wouldn't a good roofer create a saddle/cricket so the water can properly run off the roof?

    This is a botched job! The Builder or his roofer must put this right. You must have Lead Flashings to this chimney.

      HI John,

      Thanks for your response. So are you saying that when he says we have "internal flashing" before he put the bricks on chimney, it's lead flashing? I have no idea what lead flashing is but I can google it. And what's the point of this internal flashing when there is no seal/flashing on the outside where brick meets roof?

    Never heard of internal flashings.

    There should be a new construction warranty for a year. Check on this. Check with your county also. If the contractor used subs, (subcontracted things out) find out what roofing company it was, and talk to them.

    I have never heard of not putting flashing on the outside of a chimney. To me it sounds like a recipe for all kinds of water damage. Interested to hear how it turns out. Good luck.

    No! There is no workable way internally to do flashing. It is always put on the outside - under windows - around chimney stacks. Lead is very heavy and expensive - but the roof is not serviceable without it. I is Vital that it is used to complete this roof. There is no such thing as Internal flashing!

    I totally agree that there is no such thing as internal flashing. Something tells me that they were trying to cut corners and just didn't put the flashing on the outside or by the time they realized they forgot to get it or something like that, they just didn't take time to do the job correctly. I would definitely go back on the contractor and make them repair the issue. they also carry coverage to fix anything that was damaged due to their errors, you should make sure you check on that as well if there are damages inside your home from this. You may also want to check in the attic for any possible damages that could have resulted.

      I totally Agree,,,,sounds like they blew the installation...chimney and valley....Go to web and this old house has a you tube video showing the proper way to install roofing around chimney...I would also say in the north where snow build up happens you should use a touch down or rubber underlayment any where ice or snow can build up,,,no less the 3 feet up from all roof edges (this is 3 feet beyond a interior wall...if interior wall is 4 feet from roof edge that means 7 feet of rubber under shingles) this prevents ice dam and water leaks on interior caused from melting...Yes I am considered a expert...30 years as a maintenance engineer,,,with one location having over 145 Historical buildings located in the north Buffalo area.....And no leaks after I took over and corrected all issues....Attic Ventilation is also a plus keep the attic as cold as outside.....Good insulation properly installed....I hope I helped you....

    Call your local permits and codes office. Ask if the roofer or contractor obtained a permit and subsequent inspection (which is REQUIRED on all new construction). Ask for a re-inspection and go from there.


    Alternately, call the best roofing company and ask them for an inspection and repair estimate. Go back to your builder with this info.

    I would definitely take this advise. You pay too much for a home to be dealing with a mes like this!

    I agree as well. They are handing you a line of B,S, I hate seeing people being short changed and taken advantage of, either due to people not knowing what they are doing, or just trying to cut corners and rip people off. Find out who did this and make them fix the problem.

    Internal flashing.........hmm...... I was in the industry for 15 years and never heard of or saw this. I could be wrong, but it sounds like the builder was full of something, and I don't mean knowledge. If it's just as good, then why did it fail? Right?

  • William William on Jan 30, 2018

    What a line of BS! No such thing as internal flashing. Flashing goes on the outside of the chimney weaved into the shingles. The back of the chimney does need a "cricket". The builder needs to get this repaired or get in touch with the building department in your community.
