Do We Need to Redo Siding?
 
Looking for some insight into a current issue we've found related to our siding....

We moved into this house about 5 months ago and within the last couple of months found that water had leaked through one of the windows in our family room. (Side note: this was not a new leak - previous owners didn't disclose and inspector didn't notice it).

We had someone out today to look into the origin of the leak. Originally, we thought it was the window that had been improperly installed. The house is 20 years old, but the previous owners got new windows 4 years ago. While the windows were installed without proper J-channels in some area, which is part of the issue, we found a bigger issue.

We have aluminum siding which is original (20 yrs old). We also have large boards of trim midway up the siding around the perimeter of the house - I think people call them "Belly Boards." Apparently, the drip edge that the builders put in 20 years ago is essentially useless - it doesn't adhere to the Tyvek/behind the siding/wall of the house. It simply slides on over the top of the belly boards, thereby allowing water to go behind the wooden belly boards.

The contractor saw that the wooden belly boards are soft and water logged in this area. Unfortunately, we just had all of the wooden trim on the outside of the house re-painted when we moved in b/c it was rotting. Well no wonder it was rotting - water is getting behind the wood! :eek: That information also explains why the caulking the painters did around the belly boards is already cracking in many areas - the moisture is ruining it!

So we are faced with a couple of options and are stuck on what to do....

1. Do nothing. Have the contractor replace the drip edge on this one section, put the strip of siding back, and hope that water doesn't enter into the house in other areas, even though the windows don't all have proper J-channels all the way around them. With this option, we also know the wood belly boards will be deteriorating pretty quickly.

2. Have the contractor take the useless drip edge off above the belly boards around the perimeter of the house, replace it with an effective one, and leave the aluminum siding alone.

3. Have the aluminum siding replaced with vinyl, as well as eliminate the belly boards - just take them off completely. This option is obviously pricey and we had been hoping to wait another 1-3 years before having to do siding replacement.

We had originally tried to caulk areas of the siding/around the belly boards/windows, but apparently, it didn't solve the problem. After doing water tests and having the interior dry wall taken down on that wall, we've now located the issue. A bigger issue than we had imagined and we're torn on how to proceed!

Thanks in advance for any insight or thoughts....and sorry this is so long! :huh:

I think you have a bigger problem than what you're seeing. If the Tyvek is stapled/fastened to the studs, you have no drain plane or better said, there's nothing to stop water from coming in. Tyvek is not waterproof, it's semi permeable. Water will go thru it. If there's nothing behind the Tyvek, the entire siding and Tyvek needs to come off and a drain plane installed- there's no getting around it, no cheap fix. Most any siding, aluminum included, is nothing more than a decoration and is not a waterproofing. So, what's behind the Tyvek?

I'm not sure. I need to ask my contractor that! But when we did the water test today, one contractor was inside looking at the wall w/o the drywall or insulation and he said he saw water dripping down in there. So that's a good question!

My biggest concern is that while we don't see any evidence of water elsewhere, could this/will this happen everywhere in the house? This is the west side of the house, which gets hit the worst with storms, so that's probably the biggest concern I guess. But my hubby keeps wondering - if nothing ridiculously horrible has gone wrong so far, what's another couple of years until we can save up more for siding replacement without it being such a stretch. :wink:

I am sorry about your problem but I feel your pain:( I have just completed rebuilding half of one side of MY house. About 16 years ago, a "experianced & reputable contractor" Installed vinyl siding on the house just before I bought it. He failed to install the proper drip/top edge on it which resulted in water (un-noticed) to run behind the siding:huh:. This past winter that water became ice and the wall could not hold it up. That revieled rotted sheeting,studs,sill plate and top plate:censored:.I replaced all involved and am preparing to do the other side BEFORE winter. All this happened WITHOUT any outward signs or notice. Its a good thing said contractor:jester: moved out of RANGE/state. Thanks for letting Me vent and GOOD LUCK to YOU:thumbsup:

After a deep breath and a couple of "CLIPS" I also want to mention that 2 weeks later a storm packin 80mph winds peeled 40ft of my steel roof and floped it onto the other side. It probably was not wise but at the time I was ready. With a hell of a light show going on and 40mhp messing with Me , I managed to stop the 3in per hour deluge by climbing up on the roof and flipping it back:thumbup:. That only left about 3in of water above the ceiling in 2 bedrooms and a bath. WOW,I feel better already:laughing:. Have a GREAT Labor Day Weekend. Dont sweat the small stuff:whistling2:

the vertical leg of drip edge should not be ''adhered'' to the tyvek but installed behind it,this can maybe be repaired without replacing the existing siding


i'd start with option 2

There essentially is no "vertical leg" of the drip edge....that's the problem.

ahh...i see, then it ain't a drip cap,if you can stop the water intrusion and the damage is not too great you can probably get by a few years for when you are ready to reside

the damage is already done
