Is the 2/1/21 Shingle price increase real?

I just got notice of a $5per sq increase on all shingles on 2/1/2021. I know I usually throw these notices out but this one I’m being told is sticking. Has anyone else been increased? I’m in the Maryland Market

How can you throw them out? Considering everything that’s going on I start bidding increases into my jobs months ahead. Everyone should know how the new administration is going to impact any petroleum products.

They’re real. It isn’t just raw materials, it is freight too.

Unfortunately, is all too real.
