Q:I am specifically considering the re-roofing of a an older home where rafters were made with 2x4 or 2x6 and the rafter space (and possibly the attic space) does not allow sufficient space for insulation and proper ventilation behind the insulation. The old layers of roofing have to be removed in any event. At this point I am considering applying insulation boards on the existing sheathing and then a new layer of sheathing before the new roofing material. (similar to a SIP: structural insulated panel) The two issues I am concerned with is that the insulation can act as a vapor barrier. Would condensation potentially rot the lower sheathing. How is this avoided in SIP roofing panels? The second issue may be with fire regulations.: Good question and I do not know the answers. For the fire issue, call your local fire department and chat them up. Then call your building inspector and talk with him. If he's been around awhile he may have seen it done before and have some information on how it has worked out or what are must do's.

Q:I am in the process of having a new roof installed. What are my options in regards to improving its' insulating properties?: I am going to convert my loft, so was researching this subject as well. I once saw on TV (I think on Renovation program) how they make insulation from sredded paper - this was a very inexpensive and very efficient way of doing it. Also they said that the best insulation is the one made from sheeps' wool. You can buy this from major DIY stores. Have a look at the links below

Q:I need to call around and find a contractor to repair my roof. I thought it might be a good idea to at least have the name of this type of roofing correct so I don't sound like too much of a mark. Thank you in advance for your assistance.: Cheap.

Q:do I have to blow insulation in the roof of my mobile home if I install foam insulation under a meatle roof?: Install it under the meatle roof, it is a lot easier to do and will save you more money overall when you are spending money. Thanks

Q:So I'm renovating an old farmhouse with a metal roof and there is no insulation in the attic. I was up in the attic checking for leaks since we just got some freezing rain and it is currently melting I thought now was the perfect time to check. I found no leaks but I did notice the roof was sweating with noticeable beads of water in many places and many of the 2x4's that act as the frame were damp, although none were rotted (I found that odd as the house is approx. 140 years old and those are the original 2x4's. I could tell that the attic does have vents so I guess it dries out before rotting or mold occurs.. but makes me wonder if I put down some roll-in faced R-30 Owens Corning Insulation and then add a plywood floor over top if everything will be fine.. or not so fine..: If there is condensation on the underside of the roofing then you do not have sufficient ventilation of the attic. You can certainly insulate the ceiling but you do need to add soffit and roof vents to get some air circulation into the attic. You should do this regardless of adding insulation to the ceiling.

Q:were can i buy material to insulate pans and instructions to install it? I have seen many roofs with this done ,but , the lowe,s and home depots don't have .: metal pan usually refers to a pan that concrete is then poured into. If there is no concrete in it (and a flat membrane roof over that) then its called currogated metal roof. Either way they look the same. Hard to insulate cause they are not meant to insulate. there are some sold with insulation already attached - its a thin floam layer - thats a newer thing but not sure how new. heard of some mobile home mfgs and storage building builders using spray on insulation under the panels. As for aftermarket on insulating- you may be able to have spray on insulation applied from under neath - if the space is open and accessible. it looks and feels like foam, can get a bit messy , but maybe do-able depnding on your application. If its not a open space with maybe drywall under it - you might think about opening up the space in the ceiling and having blown in insulation done (much cheaper then sprayed on). Blown in will insulate just fine but someone would have to look at your application and area cause in some instances - blown in insulation can be bad for high moisture situations. also- if this happens to be in a house - by adding insulation to steel - you might be breaking fire code - something to keep in mind for safety.

Q:please help..: not unless you want little pieces of fiberglass in your hair and on your clothes every time you get in the car. They make special sound dampening materials for vehicles.

Q:I do not have extra space on the roof. Roof also tapers to drains at one end of building.: Nope. The DOW rigid insulation is an R-5/inch. So 4 inches gets you an R-20. Sorry.

Q:Can you put fiberglass insulation on the under side of roof tiles in the loft in the house?: I would be concerned that this may cause moisture to form between the roofing and the insulation. They make a special foam panel that fit underneath the roofing in between the roof rafters. They allow air to flow from the eave to the roof's ridge.

Q:Why would you not insulate between the rafters in an attic? I see a lot of houses with no insulation on the inside of the roof.: A typical composite shingle would get too hot if you insulated the roof directly underneath it, decreasing life of shingle. You want good air flow in attic, insulate above the ceilings only.
