Trouble with inspector on 12/1 pitch roof saddle!
I framed up a saddle over a valley created by an addition I put on my house. The pitch is like a 12/1. I covered the entire saddle with ice shield and shingled over it.

Now the inspector wont approve my rough because code requires a 12/3 pitch over shingles.

What can I cover the shingles with to pass inspection?

If 12/3 is required by your inspector---you will need to rebuild it to 12/3

If they accept a flat roof---ask what the town will accept.

I am not a roofer---one will be along shortly----Mike----

Code is a 2/12 pitch for shingles. The inspector can require more of a pitch though. How about a picture of what you are doing.

He stated on the Red tag that a 12/3 in required. Maybe in Michigan the code is different.

I can't post a picture, but maybe I can explain it:

I have two gables creating a valley between them. I framed up a triangle saddle in-between with 18ft 2x6's with 1/2 in ply sheating. Ice Shield the entire saddle and shingled over.

It cannot be seen, so don't care what it looks like. Just need to cover the shingles with something so I can pass inspection.

It is water tight already.

Sounds like you need to cover it with a 12/3 saddle---

He said that is what you must do to pass inspection---

I realize that you don't want to hear that---but he has spoken--

You are in a snow area so the pitch might be set but local conditions.

If you wish to find out if you can leave that existing work you will need to get approval from your building department----

Re-building is the last resort.

It is perfectly weather-proof, just looking for an inexpensive fix. The code requires a 3/12 over shingles, not metal or tar. Just looking for a loop hole so I can proceed to insulation.........

A roofer will see this post and offer a suggestion on the best method to water proof a flat roof---

But you will still need to get approval from the building department before you waste time and money and have that fail,also.

vlady88 03-04-2012 10:44 AM

All he has on the inspection sheet is : "A minimum 3/12 pitch is required for all areas of shingled roofs."

Maybe I will have to check code for metal/rolled/tar.................

vlady88 03-04-2012 10:46 AM

I have a 1/12 or maybe a 2/12 pitch now, but good call, I will have to check with the building department!

I was hoping someone would know what to do.............

Why not peel the shingles off, add 1/2" or 1" ISO instulation and .060 reinforced EPDM. I've seen sevral DIY EPDM's that come out fine. Just follow the directions and have patience.
If you're going to glue it, don't even bother with the cheap .045. It doesn't roll into glue well. And only lasts a few years.

Laymans terms?

No company would ever warrenty shingles on that low a slope no matter what you lay under them.
Even most standing seam companys would not suggest it.
EPDM as suggested is the way to go as suggested, and all the shingles will also need to go, there is nothing that can just be laid over them and have it work.

If you want a cheap solution then use a roll roofing material and flash the valleys of your dead valley.

Cheap and crappy, just as you asked for.


joecaption 03-04-2012 11:30 AM

Roll roofing is not even able to work on a 12-1 pitch. 12-2 minumum and even that would be at the limit.

Roll roofing is the lowest of the lows when it comes to roofing.

tinner666 03-04-2012 11:34 AM

Roll roofing serves one purpose in life. To make it's manufacturer money, not to waterproof anything.
