New Roof - Bonding Gutter Position

That looks a right mess.

Pointing on ridge tiles, lazy, badly finished.

Muck all over the tiles.

Joint between roofs very bad and will almost certainly leak.

Flashing on chimney not the tidiest I've ever seen.

I'd be getting um back to sort it out.

 

I rewrote my post because at my end it hadn't posted????

But it still says the same in a roundabout way.

 

Hi JP

I tiled a roof last year using Redland 49's. I am not a roofer but have done another one using 1 experienced roofer so have some experience.



There are new regulations regarding the fixing of roof tiles and ridge tiles which became mandatory from Feb 2015. Roofers have often nail the first 2 rows of tiles on the roof then every 5th row after, the last 2 rows also are nailed. The new regs now call for each tile to be secured using a fixing, i understand that there was some debate regarding this in the industry.

It now requires ridge tiles to not solely rely on a mortar bedding to secure the tile, but the use of a mechanical fixing as well.

The system I used was Klober dry ridge vent, this allowed for a mechanical system to be used instead of using mortar, as well as providing a continuous air gap of 10mm each side of the tile.

Do you know whether the roofer used breathable felt as an underlayas well as felt support trays (not a requirement, i believe bu worth having)?

You mention your house is in a middle of terrace house, the house to your left is higher so the rooflines do not merge, what happens on the right hand side, are the house on a slope?

the picture you have posted is that showing the next-doors roof, using a different tile, maybe Marley Wessex?

 

sorry i can understand you first post.

The bonding gutter doesn't look correctly fitted.

this is how it should be fitted.

 

It would be quite interesting to see how the lead work 'front aprons' has been finished to the front of the chimney. It could have been better dressed. Does look like patination oil has been used.

Its definitely not a Marley Wessex tile.

Looks similar to a Roman tile but not a double. The original tiles are also clay in composition.

 

Hi JP
I am not that up on domestic roofing apart from welsh slate systems.
Looks like Jitender has given advice already.
Sorry to hear you have been given grief over this project.
Only thing I can add is to ask BC to take a look and get an opinion to add weight to your complaint ?
Keep us updated.
cheers

I have also had a stressful time with my window install using a window company. the company were FENSA registered. It has been expensive and after 9 months a conclusion still has not been met, i employed solicitors to act on my behalf, so can understand your anger.

My local building control department are quite helpful in these matters. Although they won't get involved in the actual dispute. They may provide to carry out an inspection of the work and write this down in a log which they can can provide to you.

This is quite a good site to describe the roof replacement process, and he does have some good videos as well.

 

Felt support trays are very cheap and I don't see why the roofer has omitted to install these. The prevent pooling of water ate the eaves section. Also because breathable felt should not be left exposed for too long it can deteriorate with UV (many makers only recommend felt to be left exposed between 4-6 months depending on the manufacturer). Again these can be retrofitted, it will just mean that the first2 rows will need to be removed in order for the trays to be fitted, will be a tad difficult since the first 2 rows would now have been nailed.

You mention that the breathable felt was not secured correctly, as long as the felt is quite taut and there is not much deflection/sag between the rafters it would be ok, so a long as it has been sufficiency overlapped.

I have also noticed that the overlap of the undelfet should also be battened to prevent wind uplift. There are also manufactures of felt which don't require this extra batten to be fixed.

Many makers have this printed on the topside of the felt so can be difficult to do it wrong.

 

This is Redlands' guide to the new BS 5534 regs.

Many roof manufactures have devised their own products to secure each tile/slate.
