Question by Thank You: What are the pros and cons to building a flat roof instead of a triangle roof on a greenhouse?
my girlfriends building a small greenhouse for our apartment balcony, and we were thinking it would be easier to build a greenhouse with a flat roof instead of a triangle roof, just like some commercial building have flat roofs.

Is there a reason why every greenhouse I’ve ever seen has a triangle roof?
