Almost correct. Once the gas gun is played on the existing underlay it will pull the bitumen out and bond. If the chippings are bonded in cutback, this will do the same. It will need very good cleaning first though. Quote sounds cheap to me.

He is in Manchester :lol:

120mm Will give you .18. We did fit 240mm the other week which got it to .10 i think, but only possible due to high parapet.

Heavy gauge visquene would be usual VB, 1/2 ply will do.

Agreed, looks like a single layer too.

Existing gutter looks like code 3 to me, your stack needs pointing as well. You're off your head on that ladder. Get someone in to do the stack and the lead. Be the best 3-400 quid you'll ever spend.

Did they do the pointing with a catapult? :shock: You can't polish a turd, that all needs coming off and doing properly. Looks like a stonewald on there, madness.

:lol: Warm roof in High Performance felt would be approx £45-£50 m2 using your existing membranes as a vapour barrier. You can use inverted insulation as mentioned but will likely get root growth under it long term. Any inverted insulation will need to be closed cell, known as blue board...

PU Adhesive, for bonding insulation.

Use PU instead. TBF are expensive.

Asphalt can be used as the vapour barrier as long as its envoloped at perimeters/upstands. And liquid systems are ****e.

Nige ! I have a look of concern on my face :P

Acropoyl.

Not all woodwall slab has the channels down the side. Best way to get a fix if they are the older type is straight through with a washr/nut.

The brick upstand should of had a ply face fixed to it and the membrane carried up under the monoridge and then the ridge re bedded. If the roof is failing at the connection of the membrane and the substrate, it is the responsibility of the installer.

If the felt is in good condition (Looks like its had some bodgy patches?) You can rest bearers on a loose felt pad and build your deck off that. Make it sectional and outlet panels built in for cleaning. The height of the parapet will needs to be 1070 mm to meet regs, you may have to have a...

Flashing should have been part of the original work, surely its under guarantee?

Looks like the original flashing was just masticed to the wall and has fell down. How can they charge you for that? Shingles also look like they have been overlayed on existing as well.

We don't quote, we tender. Including Hampshire CC's work, good earner down that way. :P
