[Cob] Roofing question & thoughts

[phil]

EPDM, asphalt shingles and the like are petroleum products and if you are concerned about future cost and replacement then you need to steer clear of anything made with petroleum by-products. You might consider a wood shake of some sort. If pitched properly it will shed water and last as long as or more than asphalt shingles. If you can find someone that thatches you should consider that too. Cob house and thatch roof, they go together.

Subject: [Cob] Roofing question & thoughts



In the scheming stage.  Looking forward to real cobbing next summer.Am thinking of the roof design.  Have seen pictures of several cob houses with fairly flat roofs.  Gotta believe a membrane was used.  Some have been planted.    * What kind of membrane was used?  Conventional roofing membrane?       Some sort of swimming pool product?    * Is a membrane a good, long term choice?  As materials become more      expensive and less available, will this sort of membrane be      serviceable in future years of depletion?    * Would a conventional asphalt shingle be a better, more sustainable      choice?  It would likely be more available.  True?    * What other materials should be considered?  Tiles?Thanks for your thoughts,David_______________________________________________Coblist mailing listCoblist at deatech.comhttp://www.deatech.com/mailman/listinfo/coblist
