July 14th and we got to clearing off the roofing over our Master Bedroom.
This is what he started with today.
First Dan had to remove all the temporary flashing that he put on last winter to keep the roof from leaking. Oh well, we knew it was going to be like this.
Of course we knew that it wouldn't be good under the top layer of roofing... but this was bad. This is dry-rotted plywood. Toothpick anyone?
Most of the plywood (remember this is under three layers of roofing but on top of another three layers of material) was badly water damaged.
When he got to the South side of this section he uncovered this...
What could it possibly be?? A hidden vault? A passage to Alice's wonderland?
Nope.
Plywood, insulation, flashing... probably the remnants of an old stove or heater vent pipe.
We'll get back to this soon.
This is where we ended the day. Another section cleared. Yeah!!
Note: July 19th. 6:30a.m. Ginger says to Dan, "Hey, it's raining!" Dan, "What?!!"
Dan runs outside and up on the roof and spreads the plastic out.
Here's what it looked like... The rain was very light and very short. No leaks that we could see.

That seems like a shipload of dry-rotted plywood, Ginger! That round hole you found under all those layers of plywood is definitely from a previous vent pipe flashing. It is cone-shaped with a flange at the base, which is worked into the shingles as the roofing is applied. You should make use of it for better insulation in your house.

Well, the main cause of plywood rot is excessive exposure to moisture. The material becomes susceptible to deterioration when it is left exposed to the elements, or trapped in a moist area. It can be prevented by initially selecting the correct grade of plywood. So, what kind of plywood did you replace these with? I would love to read a new blog from you, by the way! ^___^***Roslyn Petermann***
