Your Roofing warenty is only as good as the company that stands behind it...where are you located..I have been know to do free work to people that have been shafted. I use geo-seal..its 100% silicone...dont use tar or roofing cement...it will only last a few years then crack. If the skylight was roofed right the first time you would need any silicone at all...good luck....usualy to get a roofer to come out and fix that its starts at 300.00 and goes up.... If you have a new sub-divison around you go there and find a roofer that is working on a new const house...where is only 1 or 2 guy..these are usualy the roofers just starting there company...you can get a good roofer there for a cheaper price.. Good luck, if you have any more questions you can email me and I would be glad to help you leeyohe322@cs.com leecooperroofing@cs.com I dont come here too often so it might be better to email me if you have additional questions |
