I live in Minnesota and my roofing contractor is scheduled to install Landmark TL’s on my house at the end of October. I’m wondering if that’s too late in the year to install due to colder temperatures? At what temperature would you recommend holding off on installing TLs?
Also, the contractor says he ordered the shingles (40 squares in the Shenandoah color) but that they won’t be in for two and a half weeks. Does it usually take that long to get shingles?
Thanks in advance for your answers. I just want to make sure the contractor is being straight with me.
