3 ply mod bit. Thanks, I’ll relay that to the roofers. Here is correspondence with the one I was most considering:
—is your estimate for TPO, ModBit or what other roofing surface?
ModBit – Certainteed Flintlastic was the option I quoted. Here is a link.
—what does page 2 of your estimate refer to?
This references the R-Value of ISO. I included that as a help to figure out how much we would need once we were able to identify how much current R-value you have in your house. This way we could meet code.
—I would like a Mod Bit estimate if possible.
I believe ModBit is the best under for your house based off all the trees over head. It is the most durable to impact.
—would sheet metal fascia have to be replaced?
No, we would use a new drip edge over the roofing and that would lap onto the existing fascia metal. Only in you need more than 4” of ISO would fascia metal possibly come into play.
—what would be maximum depth of insulation allowable by existing fascia?
4” is the largest that would work with standard drip edge. If we needed to go larger, we could custom bend metal to work. You still shouldn’t need to switch existing metal.
—please note mechanical fastening should not show through wood interior ceiling and exterior sheet metal fascia
With the Flintlastic application, only metal cap nails would be used for the base installation. Those only typically go through the decking ¼” As long as your ceiling is not also the roof deck (which you said it is not), then we are fine.
—do you have a written gaurantee of homeowner lien protection?
We provide a written warranty upon completion, a lien waiver from KMI and a lien waiver from the supplier.
—proof of insurance for home and all workers?
Providing general liability and work comp is easy to do and will be provided upon request. If you picked us, I would go ahead and have our agent provide certificates with you listed as additional insured.
I feel a bit surreptitious slipping this correspondence to you, but wanted to make sure I’m on the right track. It does seem to be a good outfit. All A+ with the BBB and all 5 star online reviews, but there are only 5 reviews for them.
