In reply to Taylor Bishop. Tammy - I would suggest you install a transitional piece between the old boards and the new boards that would lay perpendicular to the floor boards. That would solve the transition from one width board to the other width board provided the transition board ends up in some sort of logical place in the floor.

Thanks for explaining some benefits to metal roofing. It’s good to know that there are reflective pigments even in dark colored metal roofs. This seems very important for keeping a building cool that lives in typically warm or sunny climates.

If you're looking at changing your roofing material, you should ensure a professional inspects the old materials before your start your project. A lot of older houses used asbestos sheeting in the roof (and indeed, other parts of the house build)! Asbestos is a hazardous material that is best left to the professionals to identify and safely remove. Just my 2c (As an Asbestos Re-roof Perth Specialist)

In reply to Jay Jorgenson. Jay - Your are welcome. Just point out to the roof installer that you want a slight gap between the roof sheathing and the metal roof panel for air flow.

I’ve never thought of metal roofing being tied to Solar benefits. You make some great points about light reflection etc. We are deciding on what type of roof to do for our new house and this article was very helpful in helping us see the benefits of metal roofing. Thanks!

Metal roofing with integral airspace can be a good insulator rather than roof insulated by asbestos which can be harmful to our health. New innovation like this can be a good source of insulation with a good impact to our environment.

Really cool stuff here about metal roofing! I learned a lot about this kind of stuff in a global sustainability class I had last semester and I was just fascinated by it all. Thanks for the information and the good read!

In reply to joem789. Joem - For a metal roof to do it's proper job of keeping a house cooler, the metal need to not be in contact with the roof sheathing. The metal panels should be installed with a ventilating air space between them and the sheathing. That way the heat in the metal does not transfer into the house. It works very well this way. It sounds like your roofing metal must have been sitting down on the sheathing with no air space. And of course, more insulation is always better.

I totally disagree. Metal roofing (and siding) do not help a home stay cool. They make it more difficult to insulate. I know by experience. I lived in a house with both. The attic was always scorching hot because the metal heats up like all metal does. It gets HOT. This effectively cuts down the R value of whatever insulation you may have. You may not see an issue if you have triple insulation. But not everyone does.

For a passive solar home, insulation is VERY important. The hot rays of the sun beating onto the home is bad enough. And the last thing you need is for something to amplify the effect. Like metal.

I’ve seen metal roofs before. But I don’t know much about them. Good to know that a metal roof will help keep your home cooler in the summer and warmer in the winter. I might just have to look into getting a metal roof when I build my new house next year.
