I live in an old house (c1917)The attic was at one time used as living space back in the day when fuel was very cheap I want to make it back into useable spaceThere's no insulation up there at allIf I insulate the roof so that I can use that space again I am concerned that the roof material will get too hot and fail earlyCurrently, the roof gets ventilation from windows at eiher end of the house and there are a few roof ventsBut, if I insulate and drywall there won't really be a good place for air to circulate between the insulation and the roof itselfWhat is the best way to deal with this problem? My current idea is to vent the soffits and put a ridge vent inThat won't be easy to do though, it's high off of the ground and the wood on the soffits is about an inch thickIf I do it how much of the soffit has to be vented? Is there a better way?
Kirsten is right onA 4x4 sample is only 4 inches x 4 inchesKnitter and crochets really do like to hold and feel the yarn before they buyAnd we often walk back and forth in the aisles waiting for one of the yarns to either jump out or speak to usAt least I do:-) I would consider a gift card to one (or more) places a great giftAnd if you still want it to be a monthly thing you could alsways purchase 12 and send them to her yourself each month.
You're right about no ventilation under the roof being the main cause of premature roof failureThe best thing to do is install vented soffit and ridge ventYou'll still have a problem, though, if you fill the rafter bays with insulationThere are styrofoam venting baffles that are about three feet long by one foot wideThey are stapled to the underside of the roof sheathing, end to end, from eave to ridge in each bay(Or at least on the sloped portion of the ceiling, if you are going to have knee-walls and a flat section of ceiling.) This creates an air space from soffit to ridge ventThen you insulate and drywall as normal.
