New Flat Roof - Lead vs. Rephanol

[freddiefox]

Trying to decide on what to cover our flat roof with. It will be visible from our bedroom so I want to make sure it looks nice so was looking at either lead or Rephanol.

I've been quoted 90 pounds m2 fitted for Rephanol. However then started to investigate and saw some applications dont look that great. Would lead be massively more expensive? I did a bit of research and looks like we need code 5 which is about 60 pounds per m2 - but thats obviously not a fitted price.

What are the downsides to lead v.s. Rephanol?

Really appreciate any help - been waiting for our roofer to come back for a week, but he's too busy and I need to factor in the budget.

You forgot standing seam Zinc, which carrys all of the advantages of lead (except maybe quite the lifespan) but costs less and is not a theft risk. You're right singe plys do not look the best even with the fake seams stuck on.

Ahh brilliant - thank you. I hadn't considered it. Just Googled and it looks nice.

Does Zinc go a funny colour after a few years? Or am I just thinking of copper - Grand designs springs in my head.

Would you likely know an approx cost per m2? We have around 21m to cover.

No that's copper.

This was a recent thread //www.diynot.com/forums/viewtopic.php?t=231717&start=0 , I recall costs are about £100m². You could PM hardmetaltalking if you want a price or he'll probably be along in a day or so. He seems to know his stuff.

Great - thank you very much!

90 a m2 for Rephanol is strong money. Is that including a new deck and insulation ? Rephanol is SIG's own brand single ply, we pay about £8 m2 for the membrane.

No new deck, as we have a new warm roof going on ahead of that. However I assumed labour and Vat would be a big chunk of that price no?

Think we've been put off rephanol anyhow - the likelihood of it looking a bit ****, looks quite high!

Realised we can't have lead as we don't have sufficient height available without going for PP o raise roof for the fall required within the bays. Nothing simple and its urgent as the roof is off.

Zinc or felt are our 2 options left.

We had our low pitch roof recovered with Dryseal which is a single-ply dry fixed GRP system.

We had fake mop-sticks added to hide the fixings and give the appearance of a lead roof. Looks good.

Ah interesting Tipper - thanks you for replying!

Is that a fibreglass product? Google images make it look nice, just what Im after. However I had read bad things about fibreglass 'banging' when it gets hot/cold. Have you lived through all seasons with it? Is it above a room you inhabit?
