Here in Texas, we are not as used to prolonged freezing like what occurred about 2 weeks ago… rooftops were frozen solid here for about 3 days & on my home, we had icicles up to 2’ long.
Anyhow, I had a customer (not an installation of mine) call & ask about a lot of roof grit presenting on their sidewalk.
I went & looked @ it; their shingles are Atlas strips & the pitch is about 7:12 - 8:12 on the garage.
Is this a problem? Common? Something to worry about?
