I'm going to need a new roof this summer so I am doing research on all the ins and outs of home maintenance. There is a metal roof I am looking at that is a bit pricy but very durable and environentally friendly (it is 100% recyclable and made mostly from recycled metal). We'll see.

You know, if you decide to do this project, a series of dispatches (complete with photos) would be of great interest. The roof itself sounds interesting.

When the roof gets done, I'll see if the roofer will take before, during and after pictures and send them to me via e-mail. We have no cell phone or camera so that's the only way it could happen. If they will do that, I will post them with lots of commentary about it. I am not an expert builder or craftsman as the Canadian dude that posts on the Doomstead Diner (but not on my channel because he doesn't like me giving his builder craftsman highness any lip about Canadian fossil fuel loving stupidity. :D).

I am no expert. But, I am observant and do my homework when commenting on any subject I post on. So, in the event I am able to post about this project, I firmly believe it will aid readers in preparing for a similar project.

I have a small, uncomplicated (no gables ;D 👍) roof. The run from the roof ridge to the fascia is a little less than 8 feet. So, the two sides of 70' by 8' come to about 1,120 sq. ft. of roof plus new ridge vent, drip edge and fascia. I've got a wild idea about extending the eves out 6 inches to help protect the windows but it probably costs too much so fuggetaboudit.

It's been 13 years or so since I used the kerosene fired furnace , so I might just have the stack pulled and the hole plugged with OSB and undelayment in order to have one less potential roof leak location. I would love to eliminate the vent pipes and roof fans and the bathroom skylight so the roof has no potential leak areas. There is this great peel and stick waterproofing (rubbery and super sticky some hours after placing) that goes on the rake and from the eves up that I am looking at as part of the underlayment.

I have studied the code about the minimum distance the vent needs to be for proper bathroom flushing. It is possible to vent through the roof, though an electrical fan along the vent pipe may be required. My roof ridge vent runs nearly the length of the home and the toilets could, in theory, be vented through there. We'll see. The toilet vent pipes have always been substandard as to easy flushing from the beginning. At first I thought it was just the low water volume new type toilets. After 20 years of often required plunger use, I am convinced that the toilet venting needs help (though they are within proper code required distance from the toilets). We'll see what can be done.

In theory (famous last words), if the roof has ZERO openings on it for pipe vents, the furnace stack, the stove, fans and a skylight, AND ALL the venting goes through the roof ridge vent (with well placed roof cavity mechanical fans helping out), the cost of putting a metal (or shingle) roof would would be much cheaper, faster and leakproof. They would have to put OSB and waterproof undelayment under all those holes where the vents and so on were, of course. We'll see what is most economically feasable.


Here's a screenshot of my sketchup graphic of half of my dream roof:


I'll let you know what develops.
