I have a section of the side of my house about 8 feet wide and 4 feet high that slants away from the wall as a designer roof and is only about one foot away from the house at the greatest part of the slant. Behind it leads to some upstairs water pipes which can freeze on very cold days.
Can I blow insulation into that area without damaging the water pipes or the pitched section? There are no vents currently in this area. It is completely closed off.
My home is in North East New Jersey. This wall faces North which compounds the problem.
