Is it better to insulate ceiling or roof
Saving energy costs by preventing heat loss due to heat conduction.
Preventing the roof from accumulating moisture damage.
Ease of construction- insulating the ceiling can be easier than insulating the roof, particularly with older homes..
Is it OK to insulate roof rafters
Insulating between rafters will do no good, because the attic should be ventilated, and the rafter insulation would be between two unheated spaces. … Moisture buildup in the attic is a concern because it can condense into water, often causing mold. Good ventilation, from soffit vents and a ridge vent, will stop that.
How do you clean soffit vents
Clean the vents You should clean soffit (eave) and other types of attic air intake vents at least every couple of years, if not annually. The best way to clean them is with blasts of compressed air to blow away dust, dirt and any loose insulation that may have fallen into the soffit area.
Should soffit vents be covered with insulation
In the summer, natural air flow in a well-vented attic moves super-heated air out of the attic, protecting roof shingles and removing moisture. The insulation will resist heat transfer into the house. … NEVER COVER ATTIC SOFFIT VENTS WITH INSULATION — use rafter vents and soffit vents to maintain airflow.
How do I know if my soffit vents are working
There are two easy ways to check this. If you can get into the attic when it’s dark (or bring a flashlight but then turn off the attic lights), see if you see light when looking into the eaves – if so there were openings cut. If not there were either no openings or they are blocked.

What is the best attic ventilation
In most cases, we recommend soffit vents for intake and a ridge vent for exhaust. For homes that cannot have a ridge vent, box vents are generally the second best option for exhaust. And for homes that cannot have soffit ventilation, you will find that fascia vents to be your second best bet.
How do you remove insulation from soffits
Unfortunately, blow-in insulation can drift into the vents and block the flow of air. The solution is to install rectangular attic baffles, formed to fit between the rafters. Cardboard or thin plastic baffles allow the air to flow into the attic, yet serve as a dam to hold blow-in insulation in the attic.
Do you put insulation in the eaves
The ideal time to install insulation is when re-roofing, as fitting insulation above the rafters is the best technical solution. … To avoid condensation problems, this space must be well ventilated so vents may need to be installed in the roof and at the eaves and ridge.
Can bugs get through soffit vents
The holes on the vent strip are small enough to not have to worry about insects getting in. Seal everything you can as it is next to impossible to get an existing home too tight.
How many vents should you have in your soffit
Ideally, half the vents should be located in the soffit at the bottom of the roof and half in gable or ridge vents near the top to allow for natural circulation of air through the attic. Example: a 50′ x 30′ attic would have a total area of 1,500 sq. ft., divided by 150 equals 10 sq.
How do you fix poor attic ventilation
Many options for improving attic ventilation encourage the natural flow of hot air toward the top of the roof and out in some way. Fans, whether solar or electric, are another option. General recommendations are to have one square foot of vent space per 150 square feet of attic space.
How do you open soffit vents
If it is not hard to get to the vents, they can be sealed with plastic sheeting or fiberglass batt insulation. Unless you have a very tight sealing door, soffit vents are probably not needed. If you have a tight sealing door you may be able to leave the door slightly open to provide intake air.
Can you put too much insulation in attic
But there may be a theoretical point of “too much.” If a home is over-insulated and is too tightly sealed, moisture can get trapped inside.
