Why aren’t plastics used more in roofing?

1.87K views

It’s just that, every couple years, the house needs a new roof due to wear and tear, stuff falling on it, etc.; fine, I get it. Meanwhile, the Playskool house across the street in the neighbor’s yard has been there, taking similar kinds of abuse long enough for the original kids who played in it to have kids of their own, and not one leak.

Seems like a simple enough solution, and I’m nowhere near smart enough to think no one else has thought of this, so what gives?

Plastics have a high thermal expansion rate but more importantly most plastics that I’m aware of degrade faster than traditional materials when exposed to uv light. Since a roof is pretty much always exposed uv light this would mean that plastic tiles would be less durable than normal asphalt shingles.
