Flash...Counterflash

June 26

The roofers returned on Friday to begin the rear side of the Dutch House roof, but the weather didn't cooperate. So they'll be back on Saturday to begin.

A couple things about the front side of the roof...All in all it is a pretty straightforward roof on the front side with the only flashing required at the central chimney and where the roof meets the neighbors wall (we're attached on one side).

Since we don't want to disturb the counterflashing or the stucc
o on the neighbors house, the roofers are taking care to leave the counterflashing in place. They will gently bend it up, install the flashing on our roof, then bend it down, back into place. Here's a pic of the installed flashing - you can just see our new flashing glinting in the sun beneath the tan-painted counterflashing:


For a good general discussion of roofing on historic buildings check out this Preservation Brief from the National Park Service: http://www.nps.gov/history/hps/tps/briefs/brief04.htm

The masons were also here on Friday to work on the west chimney of the Amstel House. As I mentioned in a previous post the chimney is need of more work than we thought. We'll be building a cricket to prevent water infiltration at the upper base of the chimney from rain and melting snow. That job will be completed by the roofing company. So we'll need to coordinate the work of the masons and the roofer. Hopefully, we'll tackle that next week sometime.

June 27, Saturday

The roofers came back on Saturday to complete the tear off on the rear side of the Dutch House. I was traveling with the Society's annual bus trip to Gettysburg, PA so will see the results on Monday.

Monday is our NCCHAP workshop that discusses historic fireplaces and chimneys. We'll limit the size of the audience to 25 people to allow everyone to see the kitchen fireplace.

Until next week...
