using pebbledash?

[jeanette63]

Hi, I had my house insulated and rendered, but have a flat porch at the door and would like to pebbledash the lip of the porch. The porch has roofing felt on it which overlaps the facing edge. I have bought render cement/stones will this stick to the felt/stone?

No, and it won't stick to the felt. You might have to replce the felt with fibreglass, but I have to question the look your after. Post a picture though.

Hi, thanks for the reply I attached a pic, the house render looks lovely and clean, this edge of the porch bit lets it down I think, they left me some of the chippings and I bought render repair mortar. I just wanted the edge to have stone chips so it blended in to the house front better? thanks, Jeanette

the flashing looks untidy, but I honestly think it would look neatest, and the results longer-lasting, if you applied a trim piece, such as a white PVC moulding, onto the edge of the roof. I suppose it is about 75 or 100mm.

If you can find a roofer willing to do such a small job, there is probably something suitable used for edges of flat roofs such as car ports. You could fix it yourself if the roof is made of wood, taking care to put the screws where water will not track inside, and avoiding the flashing.

You could use wood trim, but it would soon rot.

If the roof is a thin reinforced concrete slab, be sure to use plasplugs and stainless steel screws. Rusty screws in such a thin section would crack it.

I don't think your stone chippings would adhere for long on that edge.

Thanks for the reply, I guess I may have to use pvc, I liked the idea of chippings though .

I was about to suggest the same as John, when I read his reply. But have you had a chat with the installers. They might be able to fit a piece of steel mesh on the front, and then render onto that, but at the end of it, you still need a way of getting the rain off of the roof.

'mmm, no gutter.

I wonder if that pillar is a downpipe.

No, it's just a support. This type of "porch" doesn't tend to go in for such niceties, and it's normally just a wood construction. But a firbreglass roof would direct the runoff to the side, and allow the front to be done decoratively.
