Very nice job

[@jaiforrest6387]

Super helpful thank you🙏

[@grahamharveyroofing.3399]

clever stuff

[@detumaki]

My concern is how did you attach to that curb. Glue? Peels off , corner rips in angle due to zero reinforcement.

[@davidgray5252]

Crap Product, when memory kicks in with the corner patch, it will pull and de bond Fact !

[@boing615]

why does the first patch not go tight onto the deck?

[@detumaki]

It cant handle angles at all and will create small gaps that will leak.

[@mattygrice]

Wouldn't it be better if the corner seal patch went on before the upstand no?

[@deetailing]

No response... Lol

[@leeingham4371]

I thought exactly the same. Wrong way round.

[@nickydavies4]

No it wouldnt

[@nickydavies4]

@@leeingham4371 sa should not go over form flash and rubber should not be on top of any .. for me I dont use the sa for corners as there is no need I over lap the rubber join with 3 inch splice tape and the flash the joint the sa is not needed in this application it could be worse tho he could of done this way without sa then it would of failed within five years

[@mule666]

Yes then you got more security... But like this you get more change of a leak

[@zachyontosh7587]

what type of warranty does this cover 20 year or 30 year

[@bygoran]

you either do not do roofing or you work for backyard joe roofing company 30 year warranty is not done that way

[@earthsgard]

That's shite looking, why is the patch not placed underneath first and then all else flashed over and covered,that's would drive me mad.

[@seedplanter7173]

Can't see it from my house

[@waltermatthewberg]

Not great technique with that corner but it probably wont pop out for a while at least before the check clears

[@michaelsymons8675]

wheres the corner fillet

[@Ghost-nd8up]

Not very encouraging blatant gaps where patches meet not good

[@cristiantihu5665]

Very expensive job

[@louishollandjr]

I see a leak in future why leave any wood exposed on corners.

[@AC-13]

😂

[@tommycarroll8218]

You forgot the lapseal!

[@detumaki]

Dependant on your brand lap seal is old and outdated

[@nickydavies4]

We still lap seal as per Firestone spec for commercial spec it's not out dated its needed it's just the residential market is to a lower standard

[@samgreig6947]

I usually use the Firestone system, I’ve got to say the two are identical I don’t o ow if that’s because they are actually the same product? The only thing I noticed different was the plastic backing film on the first flashing... I once rectified a job done after a cowboy had been up there, two days after it had been fitted.. an absolute mess... I thought the system he had used was Firestone except the flashings he had left behind had the plastic instead of paper foils... epdm gets too much stigma on these videos because idiots like the one mentioned above think it’s easy to do...

[@matrosnya7790]

Do not buy this crap! The adhesive is not holding the membrane! And the worst part is that you won't get any support if you have any problems! The Hertalan will simply ignore your emails, that is what happened to me.

[@samgreig6947]

Hertanlan is a different product and company mate... sounds like you probably went for the cheapest option and now paying the price 😖 do some research, do a course, then see if it doesn’t work 👍🏻

[@nickydavies4]

Iv got Firestone roofs 15 years old up to 1000 square meters still the same as the day they were laid it's the person laying it not the product
