Stone Roof Repair

Featherstone Cottage on the grounds of the old Sibly Estate / River Ridge Farm near Franklin, PA.

 From the information I have found so far, this was the home of the pump master. It matches the architectural layout of the mansion and a couple other buildings on the grounds. 

It had been used for many years as a hunting cabin and had been neglected and abused.  It was recently purchased, remodeled, and sold.

Much of the remodeled exterior roof / flashing work was poorly done and needs to be redone.

Two stone shingles, bottom left and top right, are missing from the roof area above the front door.

The lower piece has broken off just under the shingle directly above. There is a piece of aluminum sheet metal temporarily preventing the water from leaking into the house there.

The missing shingle to the top right has fallen out because of a poor previous repair attempt.

 The shingle that fell from here was intact and reuseable.

The new window and flashing installation was done poorly and is leaking.

 The stone shingles on  the roof are of various widths, from 12" to 40" wide, and thickness, from 1" to 2" thick. And range from 28" tall on the bottom rows to 18" tall near the ridge.

This shingle had broken and there was no replacement.

Behind the cottage on the hillside we spotted some sandstone that looked like it might work for our needs.

This was the largest piece we could dig out and it is just over 28" and about 2 1/2 - 3" inches thick.

With a couple chisels I was able to split the stone to a more managable thickness.

It was then cut to fit the valley angle and the edges trimmed to match the existing.

After removing the remnants of the old shingle, the new stone is installed.

The original shingles are held in place by long 20penny copper nails. I secured the replacements with 3 1/2" and 6" stainless steel screws.

I am thankful that the 3' wide stone about 6' up the roof on the left was not the one needing replacement.

The upper shingle re installed and the lower shingle replaced.

Notice that the lower and upper valley shingles don't quite line up on their edges. The lower shingle is cut and installed as it should be. The valley shingles above were reset when the dormer window and flashing below were replaced. That work will need to be re done soon as the flashing was installed poorly and is still leaking.

You can also seed a piece of the shingle to the right that has broken off at the corner. That will not be a problem. The break is below the exposure line and the valley flashing below will prevent any leakage. It may be replaced when that section below the dormer is re worked.
