How do I sort out my leaky Garage roof ?

[dUnKle]

We have an attached garage on the house which has a flat roof
Noticed few weeks back what looked like a damp patch and upon investigation it appeared there was a small leak.

Today the rain being as heavy as it is the leak is more noticable, its more of a drip than anything but certainly damp on the ceiling is noticable more than ever

The top of the garage looks like this

How do I go about repairing the roof of the garage ?
Noticed the bloke across from us a few weeks ago with what looked like a big roll of tar and grit on a sheet (image there is a technical term) laying this on top of his

I found http://www.diydoctor.org.uk/projects/repairflatroof.htm but not really sure what it is I need to buy

You'll probably have to lay down new roofing felt which is available in most builders merchants.

This may help!!

Good link - thanks

Anyone able to point me to directly what I need to go and buy (we have a Wickes nearby) and also maybe a site with actual photo illustrations ?

It tells you what you need to buy in the materials section at the bottom of the page in the link provided

Can you see where the water is coming in? You could try Flexacryl - you paint it on and it turns to rubber.

I used it for a few winters, alas this year we had to have a whole new flat roof put up.

The new roof has an incline on it now so the water runs down to a new drain pipe system.

Cheers all - feeling bit more positive
Upon closer inspection it appears to be a concrete roof with a very vin layer of what I think is called bichamen (sp?) but as can be seen in pic this is wearing away in places which happen to coincide with the damp patch

Think may get the Flexacryl and do emergency repairs on the next dry hour we get and then refelt next time we have better run of sun

Cheers - missed that
As said it appears the roof is concrete - does this make a difference ?

Looking at the contours at the edge of the roof it may be best to use flexacryll only (rather than roof felt), as there seems to be a gully for drainage on the edge. Might be worth while applying a couple of coats initially and "topping-up" every couple of years!

Wickes have a selection of sealants, both emergency and permanent:

Cheers for that

Get a tin of sealant and slap it on.

Your biggest challenge may be finding a window of opportunity between the rain.

[Kieron]

The only issue I found is finding exactly where the water was getting in. Yes there will be a wet patch, but the actual crack in the felt could be meters away.

Trial and error I'm afraid - I don't envy you having done it every year for the past 4/5 years....

Not having much luck with that house are you dUnKle?

For a temporary repair a can of car underseal works a treat, but only if you are planning to get it re-roofed as getting it off would be a nightmare. If you pop into Wickes they have a good leaflet describing replacing roofing felt. I think they have two systems, one bitumen based, the other a bit more DIY user friendly, I bit the bullet and had mine done professionally in the end.

To be fair problems are not reall as bad as they may seem - just me striving to want everything perfect

Got bit of time off this month so going to get a couple of tins of the temp stuff to put up there and then wait til spring next year and look at doing a more perm job

Been told by Wickes that it being concrete increases my options

When we moved into our house, you could see the stars through the garage roof.

If that makes you feel any better.
