If we insulated the underside of a pitched roof we d be risking heat gain and loss between the adjacent rooms below and the attic space compromising the.
Moving insulation in attic up to roof.
Attic moisture problems are often the result of heated air from the living space rising up into the attic which is not heated.
Poor ventilation can also wear down your roof prematurely causing shingles to blister due to too much of a heat build up in the attic.
If you displace insulation in order to move around in the attic don t forget to put it back as you leave.
Additionally insulation serves as a way to enhance sound proofing on the uppermost envelop of your house.
For the same reason insulation shouldn t touch the roof s underside.
If you re experiencing any of these issues and you re also planning a roof replacement it s a great time to seize the opportunity to lower your energy.
When your roof is made of roof trusses it is much more difficult to move around because of all the structure but obvious as to where you can put your feet.
And in the warmer months proper insulation and venting in the attic provides the thermal break necessary to keep all that warm air in the attic moving and out of your living space.
Another thing to consider is whether you should do it yourself or call on the professionals.
My idea is to vent the build up of hot air that has risen to the ceiling in the hotspot rooms into the attic so that air from cooler parts of the house can move in.
In the photo you see the attic framing leading up to the peak of the cathedral ceiling below.
As a result we insulate the floor of the attic to optimize comfort in the main living areas.
Insulating in and around your roof attic space also prevents long term damage from moisture build up or ice damming which results from the warm air trying to escape through the apex of the roof but instead heating up the snow.
Low cfm similar to a bathroom vent 300cfm and only in the hot spots basically by adding an inline ducting fan to the return ducts for the hotspot rooms.
Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away.
The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow.
In most homes the ultimate goal of insulation above and beyond energy efficiency is to maintain year round comfort for the rooms below.
It s easier to knock out in a weekend and it s more relevant to most people s goals when it comes to insulation.
Frequently this space is not insulated which is awful for energy efficiency.
The general consensus is if in doubt attic insulation takes priority over direct roof insulation.
The wood sheathing on your roof under your shingles can rot or become dry and brittle.
However this set up causes a different problem.
