[TheForge] ot - roofing question

[terry l. ridder]

hello;

one of the projects i was working on this weekend is re-roofing the one
old shed that is going to become the gardening shed. this shed was built
in the 1920's and was used for hogs in open pastures. the shed is on
skids that have some impressive forged rings and hooks where a tractor
or team of draft horses would latch on to shed and tow it to the next
pasture. there were two layers of modern asphalt shingles which covered
the original cedar shingles. i removed the cedar shingles carefully in
an effort to salvage as many as possible. what i came across on removing
the cedar shinglers are several large areas of a white fungus that was
spreading out with white threads. it looked like a minature white tree
that was spreading out under and over the cedar shingles. the planking
under these areas looks like it has been burned. it is blackened and
very wet. a slimey wet. some areas look like plain old dry rot. all
checkered and crumbles at the slightest pressure.

i am just wondering about the white stuff. any shingle that had a hint
of this white stuff on it was burned. the planking will be removed. the
planking is mostly 1 x 7. the boards are rabbetted on alternate sides.

ascii art:
     +---------+     +---------+
     |         |     |         |
+---+     +---+ +---+     +---+
|         |     |         |
+---------+     +---------+

given the dry rot and the fungus areas i am going to remove the planking
and replace it with either 3/4 inch exterior plywood or 1x8 lumber
without the rabbetting. i could set up the routing table to route a 1/2
inch rabbet on the alternate sides.

i need to get some closeup photographs of the forged iron hardware at
each end of the wood skid. it is amazing that they are still intact
after all these years.
