The PHMC Begins Installing New Roof on the Keith House

Well, after much anticipation, and an official state bidding process, the new roof project has begun on the Keith House.


The existing oak shingle roof was put on in 1989 (to replace the first roof the state put on the house back in the 1960s) and was really starting to show its age – both in the warped, curling shingles and in the fact that we had numerous leaks up on the third floor. Back at the very beginning of January a temporary rubber roof was installed to help protect the interior plaster from additional water damage through the winter and spring and we were told that the temporary roof could actually last for several years – we’re very glad we don’t have to test that out and the project is moving forward as planned.




Using a lift truck, Ressler Construction, out of Brownstown, Pennsylvania, is replacing the existing oak shingles with cedar, a material that will be longer lasting and is also most likely closer to the historic original. Rather than tearing off all of the old material before beginning the replacement, they’re working a little at a time to remove and replace shingles. Each tapered shingle is individually nailed to the purlins, which span the rafters, and the shingles overlap so that only about 1/4-1/3 of the 24″ length is revealed. The two man crew began work on Tuesday, August 21 and by Friday morning were about a third of the way done with the lower slope on the south side of the house, as seen above. By lunch, they had progressed to the point below:

What can’t be conveyed via the internet is the wonderful smell of the new material – if you happen to be in the neighborhood of Graeme Park, stop in and see the progress and take a deep breath while standing in front of the house. We may have white-faced hornets, imperial moth caterpillars, hummingbird moths and walnut twig beetles on the property, but we certainly shouldn’t have moths in the attic of the Keith House.
