Hi Guys, need you advice on this idea.
We've finished the north side, with 1/2 plywood and under layment.
The problem is the ice dams will still occur.
1) Close ceiling
2) Only R30 in slope roof/ceiling
3) Extreme winters, ice rain
4) History of icedams
As it is now the heat will go through the roof and melt snow and ice and create ice dams then force it's way in the house eventually. Maybe i'm wrong but i imagine it won't last very long...
Sure the ice and water shield will help but the only way i can think to solve the problem is a second roof.
It would take about 1 day of labour. Use 3/8 osb, a sheathing 2x2's Probably only cost $500 but cheap insurance on a 5k job. In the future 10-20 year the whole thing would just be pulled off and replaced with new shingles and osb. I would just sheath all on the edge.
It is a sort of insulation that 1.5" gap. It will keep the mass of ice and snow out of the house.
Should i spend the extra money and time now? The other side is already done, so can't take that off.
