Q: I have a low pitched roof so there isn't that much room up there hands and knees only.I have no eave ventilation but the ventilation is through the front and back of the house through triagle metal caps cut into the wood siding. I already have some R19 in the ceiling joists but was wondering would putting it in the rafters against the plywood holding the shingles also help insulate the living area of the house.: No blowing in some insulation will help but putting insulation against the roof wont help. the attic area is supposed to breath to avoid condensation and overheating. The only thing you would put on the roof side would be to help cooling in summer since the shingles heat up the wood underneath and heats the attic, which then works down through the ceiling.

Q: do i have to have insulation in my roof?: Maybe, you do need insulation above the ceilings (it will be between the ceiling joists/framing that also serve as the attic floor joists/framing. 1. If you have a finished attic (for a living area of some sort) then yes there should be insulation with a vapor barrier under the roof &/or between the roof framing. This will help keep heating/cooling costs down and prevent condensation from forming under the roof and doing lots of water damage over time. 2. If the attic is partially finished but used for storage only & there is attic ventilation in use also then no you don't need insulation under your roof. 3. If your attic is partially finished or completely finished but used for storage only and there is no attic ventilation then yes you should have insulation with a vapor barrier also under the roof. You don't have to have it since it's used for storage only but if you start to see condensation &/or wet areas on the wood or framing under the roof then you will need insulation with a vapor barrier installed. If for any reason insulation is installed under the roof it must be installed correctly and have in place a proper method of ventilation directly under the roof itself. All roof systems in the attic areas must have proper ventilation to prevent any possibility of condensation forming under &/or in the wood roof framing & sheathing materials that will rot the wood over time.

Q: I know you're not supposed to directly insulate the roof due to the roof getting super heated in the summer, but my walk-in (actually, more like &quot;crawl in&quot;) attic is very hot in the summer and very cold in the winter. Is there anything I can do to improve efficiency? I can't help but think I'm wasting a lot of energy just to keep my roof lasting a little longer.: You can avoid the condensation problem by simply leaving a minimum 2'' gap between the roof and the insulation. You need to fix battens on to the rafters ( at least 2'' from the tiles ) and then fix blanket or rigid insulation tight between them. The battens will maintain the air space. You then need to fix a vapour barrier over the whole thing and finish with plasterboard. No small job to do it properly ! ps you need to check the condition of the roof before you start and fix any loose tiles etc Alternatively, turn the heating up and wear a thicker sweater.

Q: the roof of my mouth hurts bad.i worked all day with sawdust and insulation yesterday.is this the problem.?: No it may not be like any type of respiratory disease ,normally this type of soe type of allergy ,if you have any doubt you can consult a doctor but are you suffering from asthma before or any person of your family belongs to this category.

Q: I am specifically considering the re-roofing of a an older home where rafters were made with 2x4 or 2x6 and the rafter space (and possibly the attic space) does not allow sufficient space for insulation and proper ventilation behind the insulation. The old layers of roofing have to be removed in any event. At this point I am considering applying insulation boards on the existing sheathing and then a new layer of sheathing before the new roofing material. (similar to a SIP: structural insulated panel) The two issues I am concerned with is that the insulation can act as a vapor barrier. Would condensation potentially rot the lower sheathing. How is this avoided in SIP roofing panels? The second issue may be with fire regulations.: Spray in foam could be an option.. you would need to talk to someone who knows more than I do.. but Ive seen great results

Q: ... building code max. (R-50)???: All the answers are OK, BUT nobody has said anything about the over hang of the house. This is not insulated and when the water runs off it comes to the roof edge and then freezes. To get away from this do what I did and move to Florida, If that is not possible get the special heat tapes for roofs and install in a "V" configuration and that will help a hole lot. Hope that this helps you out.

Q: We had a water leak in our pipes in our foundation and had to re-route our pipes along our roof. We have tried some really basic insulation for piping, but it usually deteriorates very quickly due to sun light and wind. What are some ways we can insulate our pipes effectively without having to re-insulate every month? This has to be something fairly simple and inexpensive. We aren't looking for perfect insulation, just something that will keep the water warm in the winter and cool in the summer.: Contact a local remodeling contractor and install the new piping system properly. Even a system under a foundation can be repaired, but it is not cheap to do it.

Q: What can i do to add more insulation in a addition in my house?The Roof is flat on this addition (no attic room for insulation there).Looks like it's only 4 or 5 inches thick, starts from the inside with 1/2 inch drywall and the rest is plywood, and then that black sheeting on the outside.IS THERE ANYTHING MORE THAT CAN BE DONE TO ADD MORE INSULATION ON THE OUTSIDE?, (i can't do anything on the inside since the ceiling is already low) SINCE IN THIS ROOM IS VERY HOT, even touching the celing feels warm, PLEASE HELP!: You could have foam roofing installed over the existing roof covering. Look up "foam roofing" on the Internet.

Q: fixing my room up and it gets hot in summer so i want to put some good insulation in the roof so what could i use?: How much access do you have to the attic, or the space below the roof? Are you going to be replacing the ceiling of your room and adding insulation from below, or getting into the attic and adding insulation above your room from there? If there is a large attic space above your room, and not much ventilation, sometimes you can cool the living space by simply installing some ventilation grilles to the roof to vent off hot air from the attic.
