new roofing material

[hookah bob]

for those of you putting on new shingles or any other material, there is a new underlayment called "peel&stick". It is used instead of felt paper and is vertually a watertight and non tear material.We went through jeane, out on Great Cistern, with ONLY this material on our roof. No shingles ! IT didnt leak a drop ! We did add some edge nailing along the seams but probably didnt need it. It is surely a great second defence and a miracle product. The industry name is GRACE ice and water shield. Everyone is well at Great Cistern BOB

I am so glad to hear that you are pleased with the ice and water shield. We just put some on our roof and then added metal roofing. My husband said it was fairly easy to install too!

Try to install on a cool day it is easier to handle I have seen it at Standard I don't know about Abaco

I got my roll of that stuff at Abaco between Frances and Jeanne, and put it on my sunporch. Worked great! I wish I'd found it last year.

Remember, the first layer is placed at the bottom of the roof. The last layer at the top and over the peak.Nailing all edges is with roofing nails and tin tabs is a good idea.

Thanks ya'll, my husband Bob mentioned this on the net this morning, thanks to you, and will probably go a long way toward helping others who are just now making this decision.

We first saw this product on PBS's "This Old House" about 14 - 15 years ago. We began using it then on log homes we were building in MA & RI. We would only stick it on the bottom edge (1 roll wide) of the roof to prevent ice dams (not an Abaco problem!!!) from going up under the shingles and leaking into the attic or ceiling. This use to prevent rain or air leaks is great. What's the old saying, "neccessity is the mother of invention".

Hi Pattie and Bob, your very welcome. I have been trying to post a picture of " RIVENDELL" at great Cistern ,but I dont know how to down size my picture to be accepted by this forum. The picture of the roof in the eye of the hurricane is most impressive. Thanks for all your hard work on the net , we all appreciate it . We will be returning on friday for some more cleaning and repairing. O what fun! Catch you on the net. If there Is anything small I can bring you ,please let me know BOBBY HALL

it's all I had on my roof for jeanne also - it's actually two layers of plastic - on my ridge the top layer blew off but the bottom layer stayed on - surely had me waiting for the eye so I could go up on the roof to see if the stuff stayed on.
But it all held and my roof didn't leak like it did alot in frances

[Pattie and Bob Toler]

Hi Bobby.
Thanks for the offer, but things are slowly moving forward here, and patience IS a virtue!!!! Just come on down, and bring some good vibes! Thanks again, Pattie

Let me know which pic you want up... I have a copy of your CD....call me...

There is probably more than one manufacturer of this product, if you buy Graces's Ice & Water Shield you will not have to nail it down, in fact once you put it down you will be lucky if you can pull it back up so you sort of have to get it right the first time.

Be very aware of the possibility of plywood roof sheathing deterioration and rot.

While this material will definitely seal the outside surface of your roof plywood, it will also prevent the movement of ambient moisture through the wood to the outside. This means that the attic will have to be WELL ventilated to allow the plywood to dry thoroughly from the underside. And that may not even be enough. Few roofs I have observed in Abaco have anywhere near sufficient air displacement and flow to adequately vent the attic space.

Normal felt and shingle applications have enough leakage to not completely seal the roof plywood. This material will completely lock in moisture and increase heat. Please, first investigate what has happened to those who have painted their asphalt shingle roof with elastomeric to seal it. My anecdotal analyses have found that severe rot has resulted.

We have used the material for years to seal the lower edges of roofs to prevent leakage from ice dams. It works for that purpose. However, please be cautious in what is essentially a new application. The manufacturer cautions about this ventilation issue:

If you do not have the code recommended ventilation for extreme heat and moisture areas in your attic system, and most do not, I would approach this "new solution" with extreme caution.

OK folks, just wrap the whole house in Gore-Tex and get it over with. A little pricey, but at least it will breath and shed water at the same time.

[hookah bob]

Thank you Rob for this info. You are absolutly correct. However in my case I dont have roof insulation, I dont even have an attic! so ventilation is more than adequite. If you do have an attic, I would definitly follow Graces guidlines.I've seen houses totaled in Melbourne just because the shingles blew off and then the felt. Makes you wonder what woul be worse .
