The new type of metal roof have insulation behind. As thick as 2".
It help to reduce the heat transfer and sound proof. The good of metal roof is, 1) the roof angle slope can be reduce if the depth not long enough for the roof drop. 2) water leaking. |

QUOTE(brianccg @ Oct 5 2019, 09:06 AM) Thanks enlighten, I saw there are many new housing project using metal roof and not sure what is the outcome. Still in clay roof. It's original roof like normal house.Are you using the metal roof too? Mind to share what is the new type of metal roof before? Thanks  I intend to change the roof and decide to use metal roof. Most important is not leaking, heat insulate and noise. Since the metal roof improve alot from the old generation and solve the 3 issue, should give a try. The contractor said cheaper also. That I ask back 5yrs ago. Not sure now. |

QUOTE(driftmeister @ Oct 5 2019, 06:25 PM) How easy/difficult to install? Sloopy won't have issue with leaking for RC roof. Only aging than start to leak. workmanship too.I am extending my DST at the back, but my roof is too sloppy, can only do RC roof, which I am scared of leaking in the future. When it not enough sloop, than it will leak in as the rain storm water cannot fast enough to flow away from the roof. So metal roof solve such issue. As metal roof don't have gap between. It is 1 pcs all the way. |

QUOTE(kimzee @ Oct 8 2019, 10:30 AM) I have these metal roof with insulation foam and a layer of heat insulator. Pretty common such leaking for metal roof. Very good in heat insulation and no need for another layer of insulation material above the ceiling. Noise level is minimal and the roof sloop can be less than 30 degrees. Only problem is some leaking from the "nailing" point where the workmanship is bad (did not apply the silicon properly before nailing). If you fix it, makesure use the nail/screw with insulated. Than further apply with silicone caulk or RT silicone. Those that can stand the heat. Not normal silicone. Double protection last very long. |
