My garage (in Toronto) is separate from the house. I had the house roof do= ne about 9 years ago with an architectural shingle and there were 7 package= s of it left over. The roofer left them with me so they have been sitting = in a corner of the garage ever since.=20
I am wondering if it's ok to use those shingles now that I have to replace = the garage roof. Will the glue be ok?=20
Of course I'll have to buy more of them since they won't cover the whole ar= ea.
