Water coming in through deck bolts

During a heavy rain our ceiling started to leak along the the support beams and began to pool on the floor in one spot. The source of the leak coincided with where the bolts from the deck outside lined up with the ledger board. Its rained several times since but the leak has not returned. It was a heavy rain that caused it, but Im concerned that if it happened once it will happen again and I'd like to ensure that there is no further damage in the future.

What is the best way to determine where the fault is?

Hi there

If you have the access to inspect that water leak, by removing some drywall, that will help locate trouble spot but, first read on before you start tearing down, least evasive first!

From my understanding it sounds like there was no step flashing adhered to the top of the deck board, and no water proof membrane to seal off between ledger and exterior, if that is the case pending on what kind exterior you have, seriously look at that top board of the deck closest to the house, and step flash and waterproof membrane that area, if that all exists than you will have to do a full inspection and water will be required. Remember that the leak may not even be from the deck it might be somewhere else completely.

Good luck.

Good Morning:

The main question that I have is: "Is the ledger board flashed?"

By what you have said, water is running down to the top of the ledger, over the edge and penetrating in where the bolts are. Normally code is to have the flashing under the siding and over the decking. with the slope that is required on decks, this directs the flow away from the house and therfore the ledger should not get wet.

Is this the situation that you are speaking of? Pics would help.

thank you for taking the time for the quick reply.

I have included some pics from inside and out. Our house is ten year old stucco and this is a first time event so i think it has all the necessary parts.

What type of contractor is the best to fix this?

Thank you in advance.
