Torch-on Felt Leaks

bio

Hi, I would like to ask your opinion re my flat garage roof with torch-on felt.

When the weather is very wet for several days about 4 damp areas appear on the ceiling and a couple cause a slow drip. The roof is concrete and has large cork tiles bonded to the inside ceiling. The felt job was done about 20 years ago and looks like art, very good joins, no bubbles etc. There are no visible breaks on the surface.

I know there are products to reseal the joins but considering the age of the felt its probably time to replace it. Any suggestions or recommendations for somebody to do a high quality job in southside Dublin?

I guess the best thing to do would be to get the same guy who did the original job to return but I have no trace of his name or number.

Thanks.

It needs to be re felted, torched on over existing felt Not all builders can do it and is dangerous if near an a roof as there is a fire risk if not careful with the torch.

i know a few people other than myself that have done this type of work, but none in dublin

you are over exagerating mate, i used to do them all the time until i got fcuked up, there used to be a few types of felt. one of them is supposed to last 35 years, i have that on my back build, its there since 93, no leaks yet. i done it my self

personally i do not rate torch-on felt at all, there are much better products out there.

Asphalt is the only job for this, will last longer than yourself. Ideal for concrete roofs! A little more expensive than a good quality felt but a million times better. Its also jointless. Cant recommend it enough! But like all work make sure its done by reputable qualified tradesmen that specialise in this area. Not Paddy Joe the local guy who will give it a lash, "Shur it can be that hard"!

Poor Uncle Tom

The average lifespan of torch-on is 20 years if laid properly and does not have any person traffic.

Torch-on got a bad reputation because of the harder to lay mineral felt which has a lifespan of 8-12 years.

Anyway for its cost it is quite good. There are alternatives out there now, just google Flat Roof Construction Materials.

No Insurance company will cover after 7 years that's the limit it used to be 10 that's what I meant if its been recovered within 7 years no prob they will sort you out
