Low Pitch Roofing Questions

[Markfothebeast]

I'm not a roofing professional by any means. I'd hired a "roofer" to replace the roofing. He failed to use common sense and did not use rolled roofing nor even suggest it. This is because of the low pitch, roughly 1/12. I did the tear off as I had to replace some sheathing. As I watched him work like a slug, I was unsure if he knew what he was doing.

After the guy had failed to appear on some days and lack of work hours, I'd grown frustrated. When I literally forced him to stay for a full 8 hours, his largely rotund, obnoxious, and ugly whale-of-a-girlfriend would appear and scream at the top of her lungs. Than she'd sit in the driveway awaiting his departure during the times I forced him to continue working.

I'd had a fall out with this roofer and had no choice but to find someone else. I than found another roofer who lasted about one day and mysteriously vanished. A friend of mine came to look at the roof and immediately refused to shingle the unfinished areas due to the pitch. He suggested rolled asphalt roofing instead. I quickly found myself attempting to learn about the world of roofing.

I returned the remaining shingles and had asphalt rolled roofing delivered. Now for the part that confuses me; Menards website failed to describe that this rolled roofing product is a "2-Layer" system. So I did not have this "base layer" ordered. The online manual for this roofing material is unclear whether it can be used without the base layer.

-Can asphalt rolled roofing be used without the "base layer"? It looks just like ice and water barrier to me with a larger price tag but is plastic coated.

-Can this asphalt rolled roofing material be used with synthetic underlayment? I have part of the roof covered in this underlayment currently to protect against the elements, which has done a fine job of.

So I plan to just finish the job myself and have been trying to learn. I can't locate anything online about using synth underlayment with this rolled roofing. I'm sure I'll have more questions.

What “rolled roofing” product are you looking at? Is it the torch applied one or nailed?

Sounds like a metal roof is the answer. Its designed for a low pitch roof and can go right over a simple underlayment.

Sounds like you had roofers who were less than professional and not reliable at all. I agree with the metal roofing. You can use rolled roofing and it should work OK, but I think the metal roofing would be a better all around deal.

Metal roofing would be a good choice but for such a low slope butyl tape must be used on the laps and lap screws installed.

We hot mopped most stuff like that, put down 400* tar with a mop, and lay the rolled asphalt onto the top of the puddle. It's a pain, and a few drips on your walkway are possible, but almost no amateur handyman will have the gear, and it works very well.
it does take a more fibery underlayment. it also goes fast once set up, We'd easily do a 30x30 before lunch.

If you decide on metal, at 1/12 pitch, it should be standing seam, mechanically seamed.

It sounds like you may have gotten the liberty roofing system. It’s supposed to be the hottest thing on the market. If it’s just regular rolled roofing I would assume the underpayment is just felt roll.

Is this a house or utility building ?

There are various types of roll roofing -- some will have a very long service life if done correctly.

Sounds like you need a bit more education.

I suggest attempting to find a foam roofer. Not DIY.

Last roll roof I had done on a low slope patio roof was done with regular roll roofing material and hot mop tar. Zero issues.

It is called "Weatherwood Self Adhered Rolled Roofing". The description states, "Designed for direct to deck use or in conjunction with SA Base Pro." I do not have the "Base" rolls so I was wondering how well the synthetic underlayment would work underneath.

Currently I'm still in the process of replacing roof sheathing and fascia but the weather has been iffy. I've been waiting for a few clear days to get around to it.

I feel as if I should still nail the material down underneath the overlapping areas although it's considered "self adhesive". My concern is that it may not stick as well to synthetic underlayment. However, the "base" material as stated per directions has a plastic coating to help the cap material adhere. So I'm not quite sure if it'd be wise to use the underlayment.

I will be using the butyl tape over the sheating seams. I did consider a steel roof but it was out of the budget.
