Live in Houston, very hot and humid. Looking at adding radiant and additional insulation to roof in house. We have a lot of sun, and AC bills.
we live in the desert, and got our roof coated, and instantly noticed the difference, it is much more insulated, and provides protection against leak (which was the main reason we had it done)
I am building a porch roof over an existing patio. The rafters are fabricated I-beams. I plan on putting aluminum soffit under the I-beams. On top of the roof I would like to put down a metal roof. I already put down 3/4" OSB and a rain/ice barrier. Do I need insulation and/or ventilation on top of the rain and ice barrier, or can I get away without it?
You don't need insulation for this application. If you haven't purchased the metal yet I would recommend looking for a standing seam roof system that the panel does not come in contact with the substrate and does not use exposed fasteners. If in the future you did decide to enclose the porch and add heat you could insulate the ceiling and leave an air space under the decking that could be ventilated from the eave to the ridge. A cold roof assembly with proper ventilation will dramatically reduce the potential of the metal panels sweating.
Like how does it get put in your roof?I am doing this energy efficient house.Other Questions:What is an Eave?Whats the roof on top of a patio called?What does orientation mean?What are the good things about French doors?
It can be blown in or more often it comes in large bagged bales and you cut and dump in the attic. The eaves are the portion of the roof that overhangs/extends past the wall. It's usually called a patio cover Orientation is how the home (or other structure) is positioned on the lot. They let in lots of light and are very attractive.
Can I install rigid insulation between roof decking and shingles on a sloped roof?
Lot of info missing to give you a good answer. Thickness of insulation. Slope of roof. But what it really comes down to is the building code in your area, contact local building inspector,
Hi, my building is hot in temperature in summers, so I am finding ways to tackle the problem by placing some heat insulating materials against the sunlight on the roof of my building. I have found several possible solutions, but none of them close to perfect. 1. grass layer: hard to maintain2. heat-insulating brick: might be too heavy to carry them to the roof3. heat-insulating coating: would it be damaged if we step on them? Are there things like heat-insulating carpets that would be convenient to instal?
Closed cell spray foam applied to the inside of your roof sheathing will work just fine. It needs to be installed by a specialty contractor. Good Luck
Why is the most insulation needed in ceilings or roofs? Just wanted to know
well insulation in general is to keep the inside temperature different than the outside. since hot air usually rises, i think it is to keep warm air form escaping in winter. also you don't usually have a heater in the attic, or air conditioning so insulation will keep the air in the attic from having an effect on the air within the house. that is my idea as to why
I know when you inhale the insulation from the roof irritates the throat but what can you do to clear it from your throat after inhaling it?
it's not your throat you should be worried about. it's your lungs. wear a respirator....or at the very least, a dust mask. you only live once so make it last.
House is a bi-level. Recently added storm windows to deck off dining room. Having a new rubber roof installed would like to know if we can insulate ceiling to make the room warmer. What product do you suggest we use. we are getting conflicting answers, some say you can insulate others say the ceiling needs to breath having a rubber roof install. Please advise.
Your other answerer is correct. The little plastic pieces that he speaks of are sometimes called baffles. They look like they are corregated or wavy like the inside of cardboard. These are essential to letting air flow in the attic space. Another item that you must have are vents on the soffits or overhangs on either side of the roof. Air has to get in there somehow. There are alot of homes that are not ventilated properly and the roof decking or plywood gets discolored and rots from the inside out. Sometimes this can happen in as little as 5 years, depending on your geographical location. Rubber roofing is usually put on a flat roof system. If you do not have access to inside the framing, you cannot insulate or it will be very difficult to get insulation in there properly. There are so many variables with different houses and locations. You may want to ask an insulation expert from the phone book or even a home inspector. Good luck.
