With all the rain the past few days, this morning I noticed a small area bubbling up behind the paint on the wall.

Took an exacto knife and cut a small square to remove it and of course behind it was damp.

Cut a bigger area and the paint was peeling off more easily as the drywall was damp.

On the exterior wall, I have hardie siding. there is a flood light installed where water could have come in, and I do have gutters above the area, which are not clogged.

I took a photo of the outside and saw there seems to be a leak going behind the siding as you can see water coming down the the concrete pier.



Who should first call be to in the morning? And how screwed am I? Live in NOLA and house is 7 years old.

TIA

Hardie may have not been installed correctly, very common with the cheap crappy labor they use now. Mostly illegals.
Can't tell you how many new houses I've had to go in and rip out tubs and shower pans that weren't installed correctly.
I would cut all the sheetrock and insulation out and dry it real good to avoid mold then get an expert out to look at it

Consider yourself lucky. Leaks from above are easier to fix than from below. Now locate it before making calls.

Roof edge leaks could be as simple as a poorly nailed shingle, misplaced drip edge or poorly shingled roof valley. Check the interior upper wall and attic if possible to see how high up wetness goes. Damp framing lumber will be discolored. Pencil mark any discoloration or lose paint so you can monitor if any fixes work. During a heavy rain check for gutter backside spillover onto fascia. Roof runoff can overwhelm even clean gutter capacity. Check for spongy fascia and soffit. Adjusting gutter drop fixed my problem...I could have added an extra downspout.

Good luck. Home ownership is a joy.

Just get you or someone up there and look around. Water getting behind gutter happens a lot. But the water still needs to make it to the wall.


I've seen where an A/C vent is pointed directly at a wall and cools the sheetrock well below outside dewpoint and will cause moisture problems.

Thanks for everyone’s help on this-

Quick update:

- had a restoration group come by and cut out the wet drywall, insulation and currently drying out the area with fans and dehumidifier

- had a contractor come by and found what looked to be the culprit:






He is quoting a few options but one of them would be replacing the drip edge along the entire perimeter of the roof.

That seems a bit overkill, but I did see there were a few areas where that drip edge was bent.


Can the drip edge be fixed just in this area? Or is it common to have to replace the entire roofline?

Thanks for that- I have a 50’ run between downspouts and will probably want to add another in between.

I would replace the entire drip edge. Once they get out there with the materials it’s easier just to do it all

The fact that your siding is stained right where that issue is tells me there’s at least one more issue. Definitely clean the gutters and make sure they are installed correctly
