I would blow in a foot of cellulose at least over all the fiberglass. Use Styrofoam vent chutes stapled to the rafters to keep the soffits open and insulation back. All that is relatively cheap and easy and that would take care of any existing gaps you might have since you get better coverage with it. If you really need the attic storage space you can also raise the plywood floor over the new insulation. Also dont forget to air seal since doing it will allow your new and existing insulation to actually work and not get bypassed as it is now.

Thats something i'd have to hire an insulation contractor to do i'd assume? Thats better than just rolling out fiberglass insulation? Any idea on the cost of something like that? The area is roughly 26x40 so its not real huge.

I think its really better than rolling out batts and covers better and its fire resistant as well as insect repellant. Its so easy to blow in you can do it yourself. If you can, get the exact measurements cause at 1040 sq feet you will need about 62 bags to blow in an additional R38. My local HD and lowes in ohio sells a bag for $5.95 and will deliver the cellulose for $60. The blower usually can be rented for free if you buy 20 bags. Thats roughly $400 -$500 not including tax. Checkout http://www.greenfiber.com/homeowners/how_to_one.asp for install info but its super easy. If you hire someone they will charge you alot more probably and also do a price comparison for fiberglass. If its the same or less then use cellulose. Air seal first like I said all bypasses especially that access hatch cause to do it after you blow in is a pain.

Did you see the old roof before the new roof was put on?

What shape was the old roof in?

Was the old roof competely torn off or did the owner go over top?

Do you see any repair areas in the drywall where it is currently leaking now?

Did the previous owner provide you with a disclosure sheet on the condition of the house?

Are there any mold areas in the attic that would indicate that the leaks where there prior to your purchase of the home?

Is there new wood installed on the roof where it is now leaking?

1) No I did not see the old roof prior to the new roof being installed. I believe this roof is about 3 years old now.

2) I'd have to say the old roof was the original so it was about 30 years old.

3) Yes the old roof was completely torn off because there is only one layer now.

4) The drywall all looks fine in the house and there seems to be no repairs made anywhere.

5) The owner did not provide us with any disclosure.

6) There seems to be no sign of mold at all anywhere that I can see but I havent exactly crawled down in the attic to get a close look at the eaves seeing theres not much room there.

7) From what I can see from the attic all the roof sheathing seems to be original to the house.

By answering those questions i'd have to assume the original owners didnt have the same problem i'm having. Years ago before the ice block was put into service didnt roofers used to just flip the 1st course of shingles and then start shingling over the top of that?

Another thing i'd like to add that my dad had noticed. The new shingles are architectural shingles and he noticed that the shingles were nailed BELOW the tar strips. He always had placed the nails above the tar strips. He thought that I may end up having to apply roofing tar over every nail head. He claims the nails are only about 1" up under the preceeding course of shingles.

The attached from cmhc might help regarding attic venting, attic moisture, ice dams, and removing ice from roofs.
