Why roof flashing repair works differently in Cambridge
Nearly every urgent roof flashing repair call we take in Cambridge began as something a homeowner noticed months earlier and reasonably decided to watch.
Air-sealing and window upgrades have made Cambridge homes far tighter than they were designed to be, and a tight house starves a natural-draft appliance of the make-up air it needs.
Many Cambridge properties were re-roofed at least once without the flashing being re-detailed, leaving a cosmetic seal doing structural work.
Across Central Preston, Cambridge Centre, East Galt, West Galt and Silver Heights, the housing stock changes street by street, and the correct method changes with it. A century home with a soft-brick stack does not get the same treatment as a 2010 build with a factory-built vent — using one method on both is how systems get damaged.
If you live anywhere near the Grand River, the practical takeaway is that a roof flashing repair visit should start with an assessment, not a tool. Any crew that begins work before telling you what they found is guessing on your behalf.
