We were very happy to speak at the 2018 Heritage Commission Seminar about the preservation of Historical Roofs. Very interesting and educational presentations, learning about historical building dating by use of old maps and architectural dating by design. Throughout the seminar there was an overall theme of "moisture deterioration prevention and restoration" from roofs to masonry, carpentry and plumbing. We were very excited to see a great turnout and community interest in the preservation of local history.
