Louisville Ky Home Inspection Finds: Deck to House Connection

When we add a deck to our home, it can add to the outdoor enjoyment; but if not done correctly can lead to misery later. On my inspection Saturday the client and I saw firsthand what can happen if you build your deck directly against the house without using a flashing. When building a deck an attaching it to the homes band board, you must use a flashing to direct the water away from the siding and potentially the homes structure.

On Saturday it was raining fairly hard (actually a good thing on an inspection) and we noticed that water was pooling along the edge of the deck where it met the house. This was concerning for multiple reasons, but mostly due to the home also having wood siding. Along the edge where the deck came into contact with the house, the exterior siding boards showed wood rot, and that was only the beginning. This home was on an unfinished basement (fortunately) so we were able to observe the band board, sill plate, floor decking and the floor joists. All along this area where the house and deck meet was water damage to the homes structure. The band board and the floor decking had taken the worst of it, but all of the area had some water damage.

The repair for this can be substantial since it will involve a great deal with Statewide Demolition and then who knows what else is uncovered. Keep in mind that as you start your summer deck project that a simple metal flashing installed by Commercial Roofing Austin while you are building the deck can save you trouble later.
