FAQ

Re-roof + gutters + insulationHi. My name is Sean and I live in Adelaide. I want to get rid of my asbestos roof and replace it with a Colorbond roof and new gutters and also R3 ceiling insulation. I've had 1 quote so far for $17,000 total costs, and 1 quote for roof removal only which was $3,300. Does anyone know if I can get a cheaper quote but still get a good job done please?Roof area: 160m2 approx.Gutters: 25 linear metres approx.Capping: 52 linear metres approx.Cheers.

I am a roof plumber in melbourne I think this is a reasonable price. Materials will cost approx 8000-10000 grand 3300 for asbestos removal and the rest for labour. The best advice is plenty of quotes and keep them to their quotes. If you can get a roll of metal direct from bluescope you can get a company like apex roofing to roll it for you but it is alot of mucking around to save a little bit

Are black concrete roof tiles for my house uncomfortably hot even with roof under sheeting and insulation?

it somewhat is a query of effortless warmth absorption the darker the colour, the greater mild is absorbed. an identical applies for warmth. The darker the colour, the greater warmth would be absorbed. think of of once you dress your self to circulate out on a warm and sunny day, you're unlikely to positioned on black top? The darker shade will help interior the iciness if there is little snow on the roof. on the grounds that warmth would be absorbed, your furnace will artwork much less saving you basically somewhat electrical energy, oil or gas based what you return to a determination to put in the living house. desire that helps =)

what effect does changing the pitch of a roof have on the insulation properties and durability of a roof?

I'd have to agree with mj, your insulation in your ceiling is the major factor for heating and cooling , spec R-38 but if your going for gov. kick backs I think it's R-41 (17" of blown in fiberglass insulation). Roof pitch standard is 1' raise to 4' run, (really easy to re-roof & inexpencive). Advantages of a steep roof (less apt to have leakage problems with a worn roof, you get a few more yrs). When you have to replace that roof, price goes up for steepage.

does insulation, with a high R value, in the attic prolong the life of the shingles on the roof.

no. attic ventilation can do this

I am really confused about this science stuff! Sustainability is terrible xP

i'm designing a house it quite is a retangle on the 1st floor with an L shape on the 2d and installation into that L i choose to have a greenhouse related. My plan is to apply 2x10 or 2x12s for my floor joist that way i can insulate the ceiling of the room it is under that and the two partitions that are related to the greenhouse. no longer a lot to learn any warmth from it,yet to have plant life. If i choose to get any image voltaic benefit illl in simple terms open the door to the domicile

... building code max. (R-50)???

"R" I think stands for "Resistance" factor against heat loss. It resists the heat transfer but doesn't stop it. There is no such thing as perfect insulation. Snow itself is a rather good insulator. So even though you are only losing very little heat, the snow on top of the snow directly on the roof helps trap that heat at the bottom. So the first layer will melt.

I need to call around and find a contractor to repair my roof. I thought it might be a good idea to at least have the name of this type of roofing correct so I don't sound like too much of a mark. Thank you in advance for your assistance.

Cheap.

Hi, I have got a physics question and was just wondering about it.. Can someone pls tell me how does roof insulation work? how is it effective? How does the insulation changes the heat circulation and transfer inside a house?I know that the insulation prevents radiation from the sun and overheating.. but any more details about radiation, convection and conduction of heat pls?

Well insulation makes a dead air space (air is stagnant). Since the air is not moving the transfer of hot and cold is slowed down considerably. But since you have to create cross ventilation to reduce rotting in wood and the build up of explosive gasses. Its a crap shoot that it even does any good. Radiation is heat so that's covered by the dead air space. Convection is usually not an issue with the cross venting. Also for conduction the insulation should slow it down considerably.
