I ran into an attic that had 24"- 28" of blown cellulose!? 10"-12" is the norm around here (northeast) Seems to me there is such a thing as too much? It was applied professionaly vents weren't blocked, nice and even. Whats your take on this. Thanks
What are the streaks that I see quite often on a common aspalt shingled roof? I've asked roofers and got different answers. This can be in the woods or in an open field condition is the same. Just wondering if you fellas know what causes this. Thanks
