The Theory Posted July 24, 2023 Share Posted July 24, 2023 1 hour ago, Pouatchee said: i still love my roof despite the actual loud noises I did 1" insulated roof and it was a good decision, especially for heat. It worth it if it holds for 10 years then I will replace it with a new one. Link to comment Share on other sites More sharing options...
xtrnuno41 Posted July 24, 2023 Share Posted July 24, 2023 It is said, the screws. Tighten or replace. The sealing rings can get hard or even break in long time. But second pic shows a crack and needs attention too, fill the cracks, but have a metal brush to clean first. Capillary working of the crack can suck in water when raining. Bitumen sealing or a kit for higher temperatures, as your roof can get hot. Link to comment Share on other sites More sharing options...
scorecard Posted July 24, 2023 Share Posted July 24, 2023 12 hours ago, brianthainess said: A tin roof would be lighter and now can buy with 2'' foam insulation. One brand is colourbond. Comes in several colours which is permanently in the finish of the sheel sheets. We used the one with insulation already fixed on the underside. Roofer wouldn't do the job unless he installed a steel rafter framework first, which wasn't that expensive and done in less than 2 days. Then the very long colourbond sheets, again quite fast. The insulation worked, the house was noticeably cooler and the insulation also kills 90% of the sound of heavy rain etc. Completed about 12 years ago, still looks good, never had one drop of water come in. Same guy replaced several sheets of drywall ceiling, all in 1 day, Same day joins all sealed, next day he repainted all ceilings throughout the house. Very satisfied. 2 Link to comment Share on other sites More sharing options...

I mentioned that the roofer guy woudn't do the job unless he constructed new steel rafters. WHY? It was discovered the old wooden rafters were in a very poor condition and in many spots the wood was wet and had seriously disintergrated, fixing the colourbond sheets to the wood would not have been sensible and very possibly the wood rafters would have collapsed when the workers were trying to fix the colourbond sheets.

Colorbond can be, and is, rollformed on site, so the maximum length is hundreds of meters. I have personal knowledge of a house that used 22 metre lengths.

On site ? they only do it at their shop where I am and max length i5m to be delivered, that is the length of their 'rollform' big heavy machinery, and any bargeboard, ridge bending machine has a max of 3meters length. What you experienced is not the norm but yes anything is possible. Link to comment Share on other sites More sharing options...

What you experienced is not the norm but yes anything is possible. It certainly is normal, the machinery for that is mounted on an artic trailer so can go anywhere a tractor trailer can. It is not needed for the majority of builds, ours only needed 7 metre lengths so was formed in the shop. To my certain knowledge the artic’s have been in use in Thailand for at least the last 12 years. That a shop has a limit of 5 meters is not normal as the roll forming machines have no technical limit, other than the length of the steel roll.
