the heat welded seams on fibretite seem to be more reliable than the glued seams of epdm but a good installation makes that a moot point and therefore fibretite aint worth the money.
Oh fibertite I have no idea, But as with any system it will depend on what insulation, and fully adhered or other type.Thanks for your help.
Do you happen to know what (typically) the cost per square foot is of Fibertite and EPDM?
The property is a one story property in the Mid-Atlantic Area, currently it has a ballasted EPDM roof that has started to leak and needs to be replaced. The estimates we have gotten on Fibertite ran around $20psf.
Good standard advice about collecting bids from different contractors.
I would add just one thing about contractors.
Its OK for contractors to bid/estimate a job but dont let them spec it unless its very simple/small job or youre 100% sure of whats needed and what you want.
Hire a roof consultant to spec/design it. Unlike most contractors, a roof consultant places the owners interests first.
Its a conflict of interest for a contractor to advise on a project that he is also hoping to get.
Just a few things from a newbie;
I would like to share an encounter I had recently on a well known collage flat roof who hired a roof consultant. After talking with him for a few hours (actually had to deal with him for almost a week) it came out that he had never ever physically even put a roof on. He had some training in class rooms and from seminars but absolutely no field knowledge so make sure you ask the consultant a lot of installation question before deciding on which one to go with.
As for product instalation, I am not a company rep, just a commercial roofer who has installed almost every type of roofing, and I know if it was my building and I was planning on staying in the building for an extended period of time I would look at a product called Duro-Last ( http://www.duro-last.com/ ). It is a little pricier than TPO or EPDM, but from my experiences the inspection is more rigorous by the factory rep providing the warranty, and the final product is a much nicer looking finish. There are a few more perks to this type of roof, factory made solar panels, no dollar limit warranty, a TRUE cool roof. I hope this helps a little.
Not tryin to bash anyones thoughts, I just have seen alot of problems with duralast roofs. Granted installation as with any roof is a big key to it all. From what I have seen in my area is they are a throw together and walk away type of deal.
as far as warranty goes, are you saying duralast covers the buildings contents? Most of the the time NDL is in reference to materials and workmanship, now if the contractor is on the job thier insurance covers the contents of the building if anythign happens. As far as after the job is over it would be the building owners. Now this also leaves alot of gray area. But as far as a person's home very few manufactures have warranty coverage its a contractor warranty.
I guess ive never seen a manufacture cover inside contents. Usally thats the contrators insurance, thats why the boss gets so pissed when it leaks . Yes craftmanship or lack there of is key.Now as far as I have read and been told the warranty covers contents inside the building as well. The warranty falls on the installer for the first two years then after that it becomes Duro-Last's. As for residential there is no warranty excluding the material warranty of 15 years. The commercial warranty comes in either a 15 or 20 (must be 50 mil + installed).
As for installation is concerned I totally agree it is all about craftsmanship, but I have come across all types/materials of roofs that were put on with the shottiest craftsmanship. It all boils down to pride. I am actually going to be getting a little more experience with Sarnafil so I will start a new thread after a few weeks of working with it to give my opinion on the differences between the two. Also going to be installing a few Rhino Bond roofs which as I was told were created to compete with Duro-Last, so I will also be giving an opinion on that. If you are Interested in seeing a Duro-Last warrenty let me know I'll see about getting you a copy of both the 15 and 20 yr.
