This is my go to Flat roof finish with Tommy 

Absolutely!!

i work on commercial plant equipment, i've been to a few sites now where i've been told i can't even walk on the roof to work on air handlers in case i damage the membrane. i'm no roofer but to me it seems like the fibreglass stuff is the most durable

@@cliveramsbotty6077 that is true , but I work for timber manufacturing and can't say fibreglass handle any movement from a deck especially in harsher climate variants like the UK. up here in Scotland and I can't really vouch for GRP fibreglass after getting many quotes for new flat roof, a lot of grp kits and have a go heros with GRP it would seem based on the varied quote prices, dearer quotes were the felt and hotmelt and single ply. The temp differentials and snow loads have caused grp fibreglass to crack. Timber wants to move and the fibreglass doesn't. We've decided to go membrane simply because it's more sympathetic and less likely to fail in such way but more likely to fail to foot traffic etc. each to their own I suppose!

Theres single ply roofs here in ireland for 30+years covering thousands of m². They'll begin to fail at this age, but so will others

A ZX M. 😮😮b😮

@@neilmcclean9314 exactly 💯 my point

The wear on the single ply will be will be governed by the dimensions and number of load bearing pads, no doubt Robin will adopt a ''belt and braces'' approach to their number and size. I worked on supermarket and petrol station consruction projects all over the UK for decades. Trocal was the go to single ply on the majority of those, aircon units and worker access walkways are all over the roofs and I don't remember there being any problems. Flat roofs were always a ball ache until the introduction of single ply systems.

Balustrade will probably be fixed to the decking?

Solar is fine with the correct support system

These where a client supply so I am not 100 percent sure, I will try to find out

hahaha no one knows

EDPM is a great product that come in many guises, from thickness and composition, so like all products there is always entry level and high end, it is super popular for single sheet applications such as the average garden room or average loft dormer where you can bond down a single sheet and trap the edges with a trim section with no joins and indeed I know many trade mates that do this, its just a matter of specification or choice, we tend to get involved in roofs that are large that has multiple fall directions lantern light up stands, parapets and roof and wall abutments that are raking and vertical, so we only use Evalon by Alwitra that is installed by approved contractors such as Tommy and the client will receive a bonded guarantee, summing up EDPM can also be in strips and bonded but..... it needs care like any other system when being installed and sometimes over large areas EDPM has been known to shrink and pull the seams

​@ukconstruction Thanks, Robin. So makes sense for more involved installations. Mine is an L shaped loft, the only complication wouid be the step where the two dormers join. There's actually hardly any step which potentially could make it tricker. I don't suppose you could recommend me a decent EPDM supplier? Currently looking at rubber4roofs. Thx

@@plummetplum they are local to me, pretty good company, check the thickness and go for the thicker version

​@@ukconstructionHow about that 😊. Yes I would go for the thicker one. Thanks Robin.

it is spaced off by 15mm and the cladding has a vent strip at the top and is set down 15mm behind the trim

Warm roof, only above the OSB deck and a clear ceiling void

I am not entirely sure but it will be probably minus double figures, the product is used all over Europe and Scandinavia

@@ukconstruction Thanks great RU-vid channel especially for reborn diyers

those upstands are a sealed unit with their own insulation

@@cliveramsbotty6077 thanks for response it looked like they don’t contain much if any insulation and that’s why I thought about thermalbridging or risk of condensation

It's my preferred material as it comes with a proper bonded manufacturers warranty and can only be fitted by properly trained and approved roofers, there are some good products if used correctly such as Fibreglass or liquid but in the wrong hands things can go badly wrong!!

Possibly, I would pull the fibre glass up first

Its about £100 to £150 per m2 with the PIR (depending on insulation specs)ex Vat as a guide

Through an approved contractor

This is Evalon VSK by Alwitra

The seams are bonded by melting together

Where is the Glue?

It's all about the correct building process, I have 300m2 of flat roof at home and never had a problem, nearly every commercial building or tower block also has flat roofs, the problems arise from crappy products and poor building

incorrect. Flat roofs work well when the person doing them has the right experience and training. Industry / government has reduced what used to be a trade and a craft - honed over many years - to nothing more than a service they think anyone with a few months of 'training' can provide.

Yes very much, Sarnafil is also a great product

Why?

@@Wgnwtb Looks,longevity and roofs aren't supposed to be flat.

Only use an approved installer, the roof comes with a 20 year warranty, I have had many hundreds of square metres of this put down and never a problem, have you got any footage or pictures of a bad Alwitra roof??

​@ukconstruction Robin you get paid by companies like this your going to say great things you've made at least 2 videos on them.

Never been paid by the company, I do this video because I believe in the product and use it

Sounds interesting, happy to do this, send me an email or direct message me at Instagram to discuss

There is an outlet at the end of each box gutter
