Q. Which type of roof material is very slippery when dry?
Oh, and Joe Hagarty… “manufacturer’s recomendations” is not the correct answer.
Darrell, nope… keep guessing.
Sorry Nick…that’s the slipperest I’ve come accross? but I’m sure I haven’t seen em all. I guess I’ll find out in a few minutes though. I’m just amazed to be the first to answer…that’s a win all in it’s self! even if it’s wrong.
It’s a tough question.
Would that be clay tile roofing.
Due to the surface of a fired clay a glazed surface exists and has a low friction co-efficient. Dirt would probably assist with slide factor… I would not walk this roof even when dry not for just damage reasons but “sliding reasons”…
Wood shake or shingle roofs I have found to be very slippery when performing work in the wet months… But I guess all roof types are found to be slippery when wet…
But a “slippery when dry” roof is hard to come buy… LOL
How about asbestos-cement shingles.
I’ll give you a hint… there is a class action settlement regarding this roofing material.
Cement, Nature Guard shingles
The suspense is killing me,…I can’t think of anything as slippery as a sheet metal roof. They use them alot in the mountains and areas with heavy snow loads as it just slides right off.???

Actual answer provided by NCE is “Masonite Woodruf wood shingles”
Something about lifespan and not meeting the H/O expectations…
