Clay roof tile query


T

The roof of my proposed kitchen extension will need to have a 15 degree
pitch in order to tie back in to the existing ridge of my garage roof.

Are there any clay roof tile products (in the UK) avaibable that would
suit such a shallow roof pitch?

Other than a flat roof any suggestions for any other alternatives?

thanks

I think 15-deg slope would qualify as a flat roof...

I think 35 degrees is normally a minimium for regular clay tiles. Lafarge
have interlocking tiles rated for 25 degrees. They also have a metal "tile
effect" sheet called KAMI that works down to 10 degrees.

At such a shallow angle it might as well be flat. How far away do you have
to be before you can see the roof?

Could you create a new and gable running 90 degrees to the garage?

Metal roofs go well with tile, colored the same as the tile.

I would not take the risk of any metal, clay tile or similar on such a low
slope in a country where rains are frequent. Also check the winds in your
area; Strong? which main direction? etc...

Moreover, you will tie back the new roof to the ridge of your garage, so
water flow over your new roof will be probably higher.
From a roof waterproofing point of view, the best is to treat it as a flat
roof.
Now, you may use a cosmetic system:
- Plywood or OSB deck over your purlins
- Bitumen base sheet nailed
- 4 mm black finish modified bitumen membrane torched.
- Bitumen shingles NOT nailed but adhered to the bitumen membrane (Check
with shingle manufacturer re. what adhesive to use). For sure, choose a
shingle colour that matches your other roofs colour.
All that to be done by a professionnal roofing contractor. Seek his advice
re. treatment of the tie back, delicate point.
Cheers

15 degree angle is 3-1/4:12, which is not all that shallow of a pitch.

Monier concrete tiles can be installed as flat as 3:12 with no special
provisions, and flatter than that if special installation procedures are
used.

Dan there are metal roofs designed for flat roofs.
Agreed.
But I have seen few of them.

We have a clay barrel tile roof over trusses @ 3 1/2 in 12, absolutely
no problems, in central TX, loads of high winds and heavy
rain..although we had a really good tile team, really well done..
