Question:

We need to remove are old roof insulation, how shall we go on about it?

The roof does not have fillet under tiles, our house tends to be very cold and we want to remove the insulation and put a knew one, will our house be warm? any tips and advice.thank you for your time

Answer:

I was an insulation installer for a time and this is what we did. We never took out old insulation; this is even when we blew it into the walls. We used cellulose wood fiber aka recycled paper preferable news paper and phone books. After the stuff was ground up Borax and Boric acid was added to make it fire proof. This stuff was blown in on top of the old stuff, usually 6 to 8 inches. All you do is have one person in the attic who sits down, with a hose in hand you plow it in and take measurement as you move along to be sure it is the thickness you want. Try to keep it even and smooth (like icing a cake). The other person stands next to the blower, which is place outside our in the garage (ours was in the back of a truck). This person must keep the hopper full and walk from the blower to the attic to physically look at you for safety reasons. Both must were face mask over your mouth and nose, you may want to wear goggles as well. I didn’t like goggles because they fogged up. Before you start work out emergency calls and other communication. We did this by turning the blower on and off with the remote switch (which you must have in the attic). If you take the square footage of your attic to the store the sales person can tell you how much you need. This info use to be on the back of the bag and it is easy to do. Make sure you have the correct number of roof vent for the square footage of your space. Have a fun time doing it and it will be over in no time! The blowers may have the formula to figure how much you can do per square foot per hour. This will let you budget your time better, remember that formula is usually how much can be blown per hour; the other task will eat into that time frame. To do the side walls is a bit more involved, but if you need help with that as well I would be glad to tell you the details.
why remove its a pain and if its old it could contain asbestos. just add best thing is to get the crumbly stuff they either blow in or you can buy it in sacks and just fill the attic rafters in the case of insulation more is more!!
Don't remove the old insulation , put new insulation over the old , making it double insulated. As suggested above blown in insulation is really good
i guess u mean attic insulation, it all depends on the type of ins u have, but why remove it ?, just add more on top..i'm not sure where ur located, the amt of ins depends on ur climate...here in Ontario, Canada, the code req's R40 for attics...but R32 is just as efficient
