existing metal roof insulation: "I have an existing corrugated metal roof that was placed ..." - Joey Thibodeaux (2/10/2003) | Insulation Concerns | Archive

I have an existing corrugated metal roof that was placed on a new home about 4 years ago. The roof has been leaking in about 4 places. There is also a cold draft that stays in the house during the winter and my heating bill is high. It also affects my cooling bill. When the roof was installed, the owner did not put any insulation between the roofing material and the studs. I have a metal home. The owner put the roof on under his supervision, so I know that I can not go back on anyone. I would really appreciate some help on how to solve some of my problems. I have had numerous metal roofing companies look at my roof but they all seem to have different ideas on fixing them.

i live in an old house with a tin roof. i am interested in finishing off the attic above my detached garage. how should i go about insulating the roof and providing ventilation. also, my house attic is extremely cold and the cold air makes its way into the rest of the house through the stairway. the floor in the attic is insulated, should i insulate the roof? condensation develops on the inside during the cold months and i am afraid it is going to damage the roof. thanks	Guest User 2/11/2003	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/1598/find/
Condensation can be very damaging. It occurs when warm moist air hits a cool surface. To avoid condensation, you need good ventilation so that moisture which migrates into the attic can be carried out. Strong insulation on top of the ceilings below also helps. If you do finish off the attic and create, in essence, a cathedral ceiling, you need to have a vented airspace of at least 1" between the insulation and the underside of the roofing or roof decking. This airspace needs to have positive airflow with intake at the bottom and exhaust at the ridge.
