I paid $600 CND for the install last spring (about $500 USD at the time) I supplied all the parts which cost me $425 CND.The original quote sight/unseen to install was $450 CND but my roof frame was missing the bar that holds the center portion of the roof material to the frame and one of my latches needed some attention.I would suggest that if you are uncomfortable doing such a job to not attempt it and let a professional do it.Make sure you see the guys work or get references.I have seen some crappy professional installs.If it is done wrong (off center, wrinkles,etc...) you will not be too happy as it will look like crap if you do this.I would say patience is key and to use your old top as a guide.Take plenty of pictures for reference if you do decide to tackle this project. I think i would attempt my next top install myself after successfully tackling the inground pool i just put in but i am happy with having a professional install mine and would say it is worth the money.
