Older roofs that have been repaired before
A great deal of the residential stock here has had roof work done at some point, and not all of it well. The recurring pattern we find is sealant used where flashing should have been: roof cement smeared over a chimney junction, a pipe boot patched rather than replaced, or a valley caulked instead of re-formed. Those repairs hold for a few years and then fail, usually worse than the original defect.
- Roof cement over flashing that needed replacing
- Multiple layers of shingles hiding decking condition
- Pipe boots repeatedly patched rather than renewed
- Previous repairs concentrated around a single recurring leak
