I am a local reputable roofing contractor in Wisconsin. I usually order most all materials from a specialty construction supply company, as they are knowledgeable about the products, applications, and other materials needed for the roofing project.
I seen an advertisement about the made in U.S.A. sale which Owens Corning Duration Premium dimensional shingles were on sale for $24.98 per bundle, which is a great price, considering I pay $33.00 from my supplier. I was told that the materials would arrive the following week, 3 weeks later still no shingles.
Then the shingles finally arrive without the cap & ridge shingles, which took another 2 weeks to arrive. Menards needs to stick to selling screws, candy, and 2x4's, not roofing material.
