All went great until two items remaining. 1) The trim on the end of the roofing and the very top pcs. that slides on the roof to finish it off. The trim should really go underneath not on top, if it rains all will collect at the trim... not god. The very top of the roof slides onto two pcs that get screwed onto the each half of the tin roof. Was not very clear and had to make some adjustments which still turned out good. Over all good product
