We recently looked at a remarkable Buckingham slate roof that was originally installed during the Depression era. After over 80 years of standing strong against our coastal Virginia weather, this roof started revealing a few secrets—one of which was a plumbing vent pipe tucked directly behind a chimney.

The Technical "Why"

While it might have seemed convenient at the time of installation, placing a vent pipe in a "dead" area behind a masonry chimney is a recipe for trouble. This location creates a trap for debris and moisture, leading to the deterioration of both the slate and the lime masonry. Over 85 years, being so close to the water accelerated this wear, eventually causing a leak that "professional" tar and caulk simply couldn't fix.

Professional Advice

Maintaining a historic roof like this requires more than just a quick patch. To do it right, we're repairing the lime masonry, reflashing the chimney, and moving that pipe collar out into the open field of the slate roof where it can shed water properly. If you have a historic home, keep a close eye on the areas where different materials meet, like chimneys and vents.
