Every once in a while I find where the roofer has installed the roof-to-wall flashings over the top of the siding—instead of being properly counter-flashed by the siding. Installed this way, any rain/water that hits the siding above the flashing can run behind it into the roof/house structures. This first picture is a typical example of this type of poor installation. Because roofers are not usually siding contractors—especially stucco contractors—they will rarely do this connection properly.
Since time is money—-the roofing contractor is not going to properly cut back the stucco, install new step flashings and then repair the stucco. Not only that—- the roofer is not likely going to coordinate the repair with a siding /stucco contractor.
In the picture below it wouild appear that we have the same scenario, when in fact the roof had been done properly but the siding had been removed exposing the roof step flashing. In this case the house used to have vinyl siding on it and it had been removed to expose the original siding underneath.
This fact became evident by looking at the rest of the home and one could see where the window sills had been cut off to make way for the vinyl siding. This is a very common method of installing vinyl siding—however not a very good one.
Repairing these sills satisfactorily will be difficult and the roofer is not likely to take the blame for an “improperly flashed” roof. Putting the cart ahead of the horse—usually doesn’t work.
