Aren't clouds wonderful? We had some today. Lots of progress without overheating.
Would have been nice if the clouds were continuous but I was grateful for some relief from the sun.
I had the weekend off. there was a brief rain shower Friday and the tarpaulins worked fine so had a break on what were 2 hot days...then yesterday was hot too so sat most of that out as well. Gave me time to think and the more I thought about the corner the less i liked how I had it before. So I cut a small square of this flashing material and just tried in on a bit of wood. The stuff is tacky on one side and you apply a primer to the surface you want to stick it to. I just tried it out with no primer.
I was impressed at how well it moulded and how well it stayed in place.
So I reworked the corner boards. I shimmed the rafters to create a fall towards the corner. That was it for yesterday.
Much simpler to deal with.
Then i reused the metal edging I made all those years ago and trimmed the drip edge. I also fitted some wooden battens to the roof ends to glue the rubber over.
Shame the metal was about 3 inches short on length but the gaps won't matter.
The EPDM is still ridiculously heavy and the sun kept being annoying by coming out. had to lay it so the corner to be cut out was pulled back.
I decided to cut at the corner first to mark where it was... and cut it at the wrong angle! Fortunately there was enough overlap around the roof to move the whole sheet and try again.
No in progress picture but I pulled the top down and applied the water based glue to the top 1/4 of the roof then put the rubber back over.
Then pull it up once the glue had set
Reading and youtubing about internal corners it seems best practice is to glue and mechanically fix some rubber in the corner then glue the EPDM over so at the corner it is a rubber to rubber joint. On youtube they had special washers for the screw fixings. i just put in lots of mushroom head screws.
I used more of the flashing material, this time with the primer. The primer is like thinned down rubber solution as used on bike inner tube repairs. Stuck well but I did the screws.
You use water based adhesive in the middle of the sheet and contact adhesive (think thinned evostik) around the edges and up any verticals. That meant I had to do the edge and some of the middle at the same time
That done it was on to the remaining half of the roof but avoiding a triangle by the wall.
And again both types of glue at once
Now on to the corner flashing. Primer is applied to the EPDM and the wall and is put on with a bit of scourer - which is to ensure it gets past the chalk on the rubber I guess. You fold the flashing lengthways and stick it to the wall first. You stop it sticking to the deck with the plastic it comes with. Then you work it downwards into the corner.
Then you take the plastic away and persuade the flashing to stretch as you work away from the wall and onto the deck.
Doesn't look too bad from a distance
After that I did the contact adhesive on all the remaining edges. i have some trims made up to screw over the edges but that can wait for another day.
And after that..
And it's not Stella. it is home brew lager and it went down well.
