The following email was sent to the client by our project manager:
Good morning,Please find attached the pricing you requested, sorry about the delay - if there is any problem opening the attached let me know and I will resend in a different format.The documentation and internet links in the attached report detail our; Workmanship Guarantee, System Options and Methods, Credentials, 2011 Schedule Availability, Links to Manufacturers, GRS Project Portfolio and Clients, etc.Beyond attempting repairs, there are two different methods to do your roof.One method is to rip the old roof off (a complete replacement) and the other is a new Roof Recovery System.A Roof Recovery would have our crew scraping the gravel off, taking the old membrane and soaked insulation off (as required only) and then mechanically attaching a fiber board and putting a new roof over top (SBS Torch On, Tar and Gravel Mop On, EPDM, TPO, or PVC per quote).Typically a roof recovery is what is done. A roof recovery is less intrusive, it is more environmentally friendly as the old bitumen layers don't end up in the land fill, the old system also has an inherent R Value of usually around 7, it is less costly, and the life-cycle is the same as a complete replacement.However, if you find that you want or are required to completely remove the old system down to the substrate (the sheathing or metal Q deck), we can accommodate this and the pricing is included in the attached documentation also.Additionally, there are a number of different membranes available, which I've detailed in the quote. Essentially, it comes down to 1) A traditional 4ply mop on tar and gravel (BUR), 2) 2ply SBS Mod Bit (torch down or cold apply), or 3) Single ply; black rubber membrane (EPDM) or a white membrane (TPO or PVC) depending on whether you want to draw the sun in or not. EPDM, TPO, PVC are available in multiple colors, however EPDM out of the box is typically black and TPO / PVC are typically white.Single ply systems are what are being installed more and more now (for GRS singly ply is about 80%), however, we install all system types. I would encourage you to consider the life-cycle costing and maintenance / repair benefits of a single ply system prior to choosing a system.Have a read and let us know what you think - I know there is a lot of information so I'm sure you will have questions.Thanks for the opportunity to quote - it is very much appreciated!
