Tell me about Fortified Roofs...this is for New Orleans home...

helping out a family member that needs a new roof. Have received two quotes...
Quote 1: "We would install ice and watershield over the whole roof. In our opinion, the ice and watershield is really what provides the most protection and the most important aspect of the Fortified Program.
If a house has solid plywood, there is an option to tape the seams and add a double layer of synthetic underlayment. However, every time we have pulled shingles and found rotten decking, it throughout the plywood not just on the seams. So ice and watershield would do a better job preventing that potential damage than what felt would."
Quote 2: "Leak Barrier: High-quality Owens Corning ice and water shield, manufactured for TopShield, installed in all valleys, around roof penetrations, and along roof-to-wall connections. Issue with ice and water shield over the entire deck is that the roof, in my opinion, does not breathe as well. I believe the double synthetic method allows the house to breathe the best."
What is the H&G's opinion on this?

I had my friend do it with Ice and Shield. After that it is a shite ton of nails and other hardware. He did it for $1k cash and had no problems getting the certificate

Make sure you have plywood to start. Mine has slats. Would have been an 18 wheeler full of plywood which would have come with enormous cost and weight to the top of the house.

FORTIFIDE allows three underlayment options either A) tape the seams of the plywood sheathing and then apply an approved underlayment on top B) ice and water the whole roof or C) apply two (2) layers of approved underlayment
Contractors worth their weight are going to ice / water valleys, penetrations and eaves either way.
If you are using the $10K grant money from the state (Louisiana) you may be limited on which option you can choose. Ask the contractor. It seems like I remember the state was trying to simplify the process / reduce options on their end but I could be wrong.
I have a FORTIFIDE roof and chose to go full ice/water BUT I had the contractor add a layer of synthetic felt on top to act as a vapor barrier. Reason for this was A) the shingle manufacturer recommended it and B) it will make things smoother when this roof needs to be changed out.

Water and Ice is beter IMO. It is what I have on mine, but it tends to cost a bit more just in materials. You're putting a rubber barrier across the entire surface. Then shingles over it. As others mentioned, there is more to it but that is one of the most important aspects.
- shite ton of ringshank nails
- More specifics on the drip ledge
- Specific bracing or materials for venting
It's a good idea overall, and probably just how roofs should be built in this area

Do you agree with the one quote that thinks the house breathes better without the ice and rain layer over entire house?

I could have gone with just double felt.
I would ask for more elaboration and some addresses for you to drive by and observe on what issues the roofer is seeing with the full ice and water roofs.
Attic ventilation is important and when you are changing out your roof it is a great time to address those issues. I’m going into year three with no “breathing issues” to my knowledge. The house I bought has soffit intake vents and it had one broken power attic fan. I had them scrape the fan, patch the hole and add ridge vents during the reroof process.

We did ours last year around May and did the ice/water barrier. The installer did mention some in other states are opting to put something down between the barrier and plywood to make removal easier for removal but that was after he started our install. It was sold to us as you could lose every shingle one the house and you'd still have no water penetration. We went from a metal roof with just runners underneath to a fully plywood decked roof with the barrier. Selling point was insurance went down about $3k a year, so will pay for my out of pocket cost in 4 years after the $10k grant. This was in Slidell and at the time I was getting quotes I don't recall getting any other options besides the barrier.

do you have historical tress/branches hanging over the roof line? A branch stabbing the roof will render most of the below moot regardless.
