Update: After a horrendous rain storm I noticed water dripping from 2nd & 4th support beams. I did use the tape with the kit but apparently it will need some silicone. I did slightly raise the back end for the water to drain & it helped alot but still slight drips. Still a Nice carport. Took my husband and myself roughly 8 to 10 hours to construct. Overall not bad to install. Roughest part is getting that middle row of roofing on correct. Went off slightly on last 2 panels but happy my boats under cover. Nice product.
