Apex porch roof help

[xdrive]

Hi


I've created apex roof on new porch

I'm currently tiling the roof using sandtoft double roman tiles.

I've left 2 inch overhang into gutter.

I've deducted 30mm from ridge. Ive laid the first batten at bottom. Maximum headlap allowed is 120mm at batten gauge of 30cm.

Im getting gauge of 27.3cm headlap of 147mm headlap.

Total row of tiles is 5. The bottom tile can't be moved down any further.

Will I have problem fitting dry verge and what is the solution so it can work.

@noseall any help appreciated

Thanks

Sounds to me like you could easily get another course of tiles in there and still be within permitted head-lap...?

What's the pitch of the roof?

42 degrees.

If it helps the second batten of the bottom to top batten has a gap of 82cm. Definately can't get another course of tiles in.

Total 5 courses of tiles at the headlap of 147mm which is 27mm more than manufacture max.

Sorry, meant to say lose a course of tiles!

82 divided by 2 gives gauge of 41cm of batten. So 10mm headlap. Minimum is 75mm.

147 is nearly double recommended minimum gauge. You could afford to pinch 72mm from each course. Surely this is enough to lose a course, even on a short run?

I doubt you'll find dry verge units that will work over such a compressed gauge.
