I have designed and built a 1920sqft Coffee drying deck (aka. greenhouse) http://www.konamist.info/gallery/drying-deck My carpenter (who said he knew about roofing) screwed up $4000 worth of corrugated Lexan(Suntuf) by pre-drilling holes in the wrong places and then proceeded to install 13 sheets (with holes) before I caught what he had done (was doing) and let him go. I have called all the roofing outfits on the Big Island of Hawaii and none are interested in installing corrugated Lexan. Sooo... I guess I am going to have to do it myself. 1st question: What is the best way to keep from being admitted to the hospital and get this roof installed? (...or, any saftey techniques or recomendations on moving 275lbs (me) on 1/16" plastic 20-30 feet off the ground?) 2nd question: What is the best way to fix all those damn holes. Already proposed: A. Nail up a 2X2 under the errant holes using screws to plug the holes. B. Cut up a bunch of Lexan 1/2" squares and glue them over the holes (IPS weld-on #3?) C. Buy 44 16' sheets of new Lexan. D. Use clear silicone to fill the holes (not sure if it's compatible with polycarbonate or if it will will stand up to UV/water over time). Mahalo for any and all suggestions. P.S. To experienced roofers: Willing to exchange airfare and provide ohana (guesthouse) for two weeks in paradise for roof completion.
