Replacing a Flat Felt Roof

Question

Hi,

We have a leak coming through to our living room ceiling from the flat roof/terrace above. The terrace is currently covered with felt and water pools. We have had a number of trades come around to quote to resurface the terrace, most have said they wouldn't replace it with anything else other than fibre glass which we can't afford. One company has suggested removing the felt, adding a bitumen layer, PVA and then self-levelling compound with a 10mm drop/slop so the water drains off. Around the edge of the terrace they will install edge panels with waterproof sealant. Does this sound like a suitable fix as I'm nervous about paying the money to find its not fit for purpose at a later date.

Many thanks
Nic

I would put new boards on so it has a slow and put a new rubber roof on which is cheaper than the fibreglass I’m with there being no Joins It is impossible to leak

Brian · Answer

fiber glass can only be layed in certain temperatures, i suggest your roof to be stripped down fully down to joist , then apply firring strips on every joist , firring strips are a 2in timber running down to nothing to create a fall . then redeck in a 3 quater ply , i layer of primmer , 1 layer of 2ml torch on under lay , then to finish in a 5ml mineral cap sheet complete with edge details .

Why not find out where the likely place the leak is coming in from then torch dry and use flashband torch on followed by a bitumen sealant this will stop any leak should last years !! Save a bit money for the time being.

Hi Nic if it was me and I had this problem I would strip off old felt replaced wood slope so water running away and not sitting on the roof we would underlay with felt then put top coat of Finnish felt and guarantee work for ten years hope this helps you regards Gordon

Find where the leak is coming from and just torch on some felt. Or flash band with a little bitumen, but to be honest I’d say from what it sounds like you just need to get some felt torched on wherever the leak is

Epdm rubber is a good product to use. If your roof needs more fall could add firing strips and osb and then epdm rubber over top. depending on size  of roof and shape epdm come in one sheet.
