Heavy rain all yesterday shows my flat roof is leaking again. It's felt,
and about 30 years old. Been 'fixed' a few times, but time to replace.

The deck is good quality ply, so hoping that is still fine. All the
flashings etc lead. It was designed by a decent architect, and installed
by his recommended builders and roofers.

Size is approx 3.5 x 4 metre

Anyone give a rough guide as to costs - felt, membrane, glass fibre?

Access is easy so no scaffolding needed.

At my age, even felt done well is likely to see me out. But I'd consider
something better - if I can afford it.

At the beginning of 2020 I had mine redone.
About the same size as yours, but decking was chipboard and totally
fu**ed. Also 3 stories up so a couple of £100 worth of scaffolding
needed.
New roof, multi layer felt, hot tar on OSB3 boarding, cost about
£2400.

Thanks, David. I was hoping about 3k would cover it.

it doesn't matter how easy access is, it's how easy it is to fall off that
the issue

and that will be much the same for all non-enclosed roofs.

Really?

When did you last buy decent quality ply?

If I feel safe up there, I'd expect a skilled roofer to do too. It has
parapet walls.

did you not have that done with Promenade tiles a few years ago?

That is the roof terrace. This is a different flat roof that there's no
immediate access to.

Chap finally came round today. He's the builder the architect who designed
the conversion all those years ago now uses. I simply don't know any
roofers. And would rather go by a recommendation.

Interesting chap. Said he is a builder, not roofer. Who now does roofs on
his jobs himself. After getting ripped off once too often with
contractors. ;-)

And only does glass fibre. Felt is for sheds, he says. Fairy nuff - no
point in learning more than one skill if you're not going to use it.

Tim guessed right. He wants it scaffolded for safety reasons - even
although he went up to have a good look without. However, I could make use
of the scaffold to paint the window. It was done a couple of years ago.
But be silly to pay for scaffolding again in a year or so.

He reckoned about 5 days work, assuming the base is OK. The BOM from the
architect specified marine ply, so I'm hoping that's what was used, and is
still OK. There are no signs of sagging.

Found an online calculator which reckoned on about 500 quid for materials.
He's going to give me a price next week.

I have been thinkig about flat rooves. I'd go one piece EPDM. Call up a
few people and ask about a price for the job.

Interesting:

About £150 for a single-garage sized piece, plus sundries. If the decking
is in good order doesn't look infeasible as a DIY job.

prices up all the extras.

Quite easy to DIY, but whoever does it will have to overboard
the existing plywood decking with another layer of ply or
OSB3 because the water-based adhesive needs a clean substrate.

Must admit to wondering why the existing can't be cleaned, if in good
condition?

"You must ensure that the decking is completely dry and clear of any
surface debris before applying the ClassicBond EPDM Deck Adhesive. Of
course, installation couldnt be easier making this product ideally
suited for both amateurs and professionals alike".

Yoiu can also get a primer for the job.

Have a look at *Composite Roof Supplies*. I did a 3m x 2.5m porch roof
for not very much. Strangely, although I have the delivery note, I can
find no record of payment!
