Leaking Flat Roof - Trouble finding a roofer

[northernchappy]

Hi all,
My garage roof has suddenly started leaking in numerous places after a freezing spell, and I am having trouble finding a roofer to relay it.

I have been up on the roof and tried sealing the joins between the sheets of felt but not had much luck. Is there anything I could put on the roof as a temporary repair until I find a roofer?
not sure if the felt has many tiny cracks from water freezing and expanding to cause this trouble

many thanks

What have you sealed it with? Not Acrypol was it?

I could put on the roof as a temporary repair

Polythene?

A freezing spell wouldn't cause the issues; it's the water getting in somewhere in the first place that's the problem, and very likely occurred before the freezing spell. How big is the garage, and is there a fall to make sure the water runs off. Rather than relay felt, you might be better off looking at EPDM, or fibreglass rather than felt.

Post some picture inside and out if you can please.

Could it be condensation?

I used 1200 gauge dpm on my shed roof (18'0 × 9'0) 2 years ago as a temporary cover! Its still going strong (wifes not happy though ).

No it was a tin of roofing tar type stuff.

Yes its got a slight slope to rear, 18 x 18 feet square, semi detached with neibour, their side isnt leaking evrn though it looks old too.
Ive covered the joins with roofing repair stuff, and when i ran out, wrnt with the tin of tar stuff.
The joins looked a bit iffy so got the adhesive in there. (temporary job to stave off any damage to wood.
Had one roofer out, £1000 to refelt with standard felt, plus £50 for each tongue and groove board that needs replacing but should be ok

I tried glueing down a patch with the tar from tin stuff, thought it was ok but it blew off and stuck onto neibours windscreen.. White spirit came in handy and no one the wiser, they didn't see.. Phew lol

Have a look at getting EDPM; £1000 for felt is a complete rip off, and won'y last anywhere as long as the EDPM or fibreglass.

Lol.

Anyway, get some Acrypol. Brush it on, in the wet if you like, and it won't blow off.

No mate, it drips in same places, poured in until i filled joins in.

Its about 30 sq metres, so a fair sized area. On that basis the roofer is charging a bit over £30/ sq metre -Ive no idea if thats the goung rate or not. It would be cheaper than epdm or fibreglass.

1.2mm EPDM to cover that area would cost about £300 for the rubber, if you fancied having a go yourself. You cant stick epdm to felt though, so would need to strip off or overboard. Maybe an opportunity to improve insulation at same time.

But if he has Epdm he will have to reboard it.

Yes, but the job will be done right, and last.

If you will ask about the most running popular material for roofing extremely durable synthetic rubber roofing membrane (ethylene propylene dine terpolymer) is an answer of a majority. When you are constructing a house is cautious about roof as its safety related to it though since you want it to set soon. You want to make it leak free and problem free in all season. Whatever is in your hand you use to do more than your capacity? But some things are little to consider the water and not simply remain little like damage. EPDM main ingredients are Ethylene and propylene, derived from oil and natural gas. EPDM is available in both black and white and is sold a broad variety of widths, ranging from 7.5 feet to fifty feet, and in two thicknesses, 45 and 60 mils.

EPDM Coatings has over a 20-year history in the field of roofing and fortunately as long its history is old its success life is increasing every year. The reason is its consistency in quality. Rubberised roof covering has competition with other products in the market but it has decided to get win win win. Many products claim to be liquid rubber but cannot prove their claims calling themselves Liquid Rubber but there is ONLY one Liquid EPDM Rubber in the world!
