Deck Flashing question


We removed a concrete and brick patio from our 30-year old vinyl sided home due to deterioration and discovered extensive water damage to the house rim and ends of ~8 floor joists. This has been repaired and/or replaced and we are now installing a deck. I came home today and discovered that the contractors are not putting any flashing up. They say it's not necessary because they plan to butt the decking boards up flush against the sheathing "so no water will get in." Everything I've read says flashing is required by code AND we are understandably paranoid about any additional water damage. They have already installed the ledger board across the entire back of the house and hung the joists on about 1/3 of the deck. Question: Will installing just a vinyl cap flashing to the top of the ledger boards be sufficient to prevent potential water penetration? Or do we need to remove the ledger boards (and the joists that are already hung) and install a membrane behind the ledger boards as well? Contractors are not thrilled about removing the work they've already done but will do what we ask them to do. They feel the cap flashing will be enough. We want this done right and want to avoid any future water problems, but if we don't have to remove the existing work we will stay on track with budget and timeline. Thanks!

Re: Deck Flashing question


A flashing (not aluminum) should be on top of the ledger and tucked behind the house wrap which is behind the siding

Re: Deck Flashing question


We always prefer to install a peel and stick membrane behind the ledger, but it is not code. The flashing on top is code, and is most important of the two.

Re: Deck Flashing question


So, I'm wondering if the easiest solution at this point would be to use peel and stick membrane to put on top of the ledger (and tuck under the siding) above.

Re: Deck Flashing question


OK, so turns out the flashing is the least of our problems. We went out today and found these HUGE gaps in the foundation where they removed the concrete patio and just installed the rim board and ledger board, leaving these huge holes open to the interior. You can see the floor joists from the outside! And those are loose bricks just sitting on top of the foundation in the first picture. Everything is coming off so that we can complete the foundation, make sure the sheathing is present, flash, wrap, reside, etc. OMG I can't believe this! /var/folders/qr/pf5683_r8xs85k008k8wv6ph0000gn/T/com.apple.iChat/Messages/Transfers/IMG_1207.jpeg

I can't see the picture, but it sounds like you have hired some hacks.

Not sure what to do to get the pics to show up. And yeah... these people came highly recommended but that's certainly NOT been our experience.

Re: Deck Flashing question


So, we sent a very long and detailed email yesterday to the contractors outlining everything we expected to see happen. Unfortunately, much of this work will need to be removed so they can address completing and drying in of the foundation, the correct flashing and house-wrapping, etc. And unfortunately this is going to extend our timeline (our daughter is due in 2.5 weeks and this was supposed to be done before baby arrives. We just want the job done, and done well and if it takes a little longer then so be it. We are so shocked at this workmanship. We've seen their work on other jobs and as I mentioned, they came highly recommended. We feel like we have had to become "experts" and that we have to monitor and question everything they do. The relationship is becoming a bit adversarial which isn't good either. We've renovated two old houses in the past and have done lots and lots of DIY jobs, so we're not total newbies at this, but we're definitely not expert contractors either. We had one experience in the past where we let a roofing company go mid-job because they were doing such a terrible job. Feeling like this is a very similar situation.

Re: Deck Flashing question


We're in VA. We had lots of moisture damage from the concrete patio that was removed. And YES, they agreed to repair that damage (we modified the contract to add this in). They did sister new pressure treated beams to the damaged joists and replaced the house rim board. But then they proceeded to install the ledger board, deck joists, posts, etc. without addressing the gaps in the foundation left when the patio was removed and did not include any flashing. I cannot fathom how they thought this was ok. I am meeting with them tomorrow morning to see if we salvage this relationship and job.
