We have a problem that seems to be perplexing to several contractors in our area. Any help would be greatly appreciated.
As briefly as possible, we have developed a gap between the house (25 year old aluminum siding) and the chimney ranging from the top of the house at the gable to 4 ft. down. At its widest, it's approximately
2-3 inches and narrows as it moves down the house. It's hidden behind a tree that hugs the house and went unnoticed for a period of time.Our first move was to have the chimney checked. While the flashing does appear to be pulling somewhat from the roof, the chimney person/mason put a long level on the chimney and contends that it is straight. We have also consulted with at least one general contractor and other siding contractors. They have raised the possibility that the gable has moved inward somewhat away from the chimney, and that, at a minimum, the sheathing has "disintegrated" in that area from rain and elements. The siding does have "give" a bit in the area when poked, although there is no sign of leaks/weather damage on the interior of the house.
In general, we are being encouraged to replace the siding, which could use it anyway (we would pretty much have to switch to vinyl), with the ultimate determination as to the problem waiting until the siding has been removed. While I can see the logic to this, I'm uncomfortable with the "open-ended" nature of the fix (not knowing what the "real" problem is) and wonder if some of this work potentially is beyond the expertise of those who do siding ("warping" of wood?). Thanks much in advance for any thoughts as to what this might involve and potential pitfalls.
