Dry Ridge Thoughts

[Beardo]

Evening all, 

 

New to the forum and kinda stumbled upon the site when searching for information on dry ridge installations. Anyhow, I've recently had a dry ridge installed and was wondering if the job has been done right? The ridges do not look completely uniform when comparing to how they sat with a bed of mortar however I'm no roofer or have a scooby about what a good ridge installation should look like so hoping someone on here could help clarify? These are the best pics I could take as no scaffolding or ladder big enough to get close ups. Thoughts peeps...

Oh forgot to mention that the roofer suggested on installing a new ridge starter tile which a little different to what I've currently got on there but seems to think these are the right tiles for it??

If they have just replaced the ridges 

 

They are pretty much stuck with the shape of the roof 

As apposed to bedded They would have bedded the bottom two up

What do you mean 'bedded the bottom two up'? And yes, these are the original ridges that have been re-used.

I've also noticed they haven't inserted a mechanical fixing point (screw in the centre) on either of the ridge starter tiles.. How secure will they against any type of wind/bad weather?

Its difficult to see from the photos, but you can get dry ridge kits that just have the membrane and clips, and some with support trays. These are the same product but with the addition of plastic support trays that sit under the tiles, on flat concrete tiles you can get away without the trays, but on tiles like yours it is difficult /  nearly impossible to get them to line up. 

The photos look reasonably straight.

as this is just a re-ridge / hip, as @nod says there is little you can do with the shape of the existing roof. and the ridge tiles will follow the tiles underneath.  The mention of bedding up was referring to when you use sand and cement.

Yeah totally get that.. Question I now have is how secure is the system they have used. I've noticed the ridge starter tiles that they have installed do not have a screw in the middle for holding the tile in place other than the clip and screw that comes as part of the dry ridge kit - if that makes sense. 

 

Additionally, where they have done the mitre cuts at the top, how should these be secured into place? From what the roofer told me, they had simply used some sort of sealant to hold the tiles in place and thats it along with the above mentioned clips/screws.  My worry is that come some bad weather and wind, these ridges will be flying off!

The end ridge tiles are often mortered at the ends and have a hole drilled through the top with a stainless steel screw fixing to keep it in place.

Neither were done but they have changed the tiles which include a cover so I guess that kinda eliminates the need for mortar? I'd still expect it to be screwed down for added security.
