leaky garage roof
Meeerrrk - 11/2/09 at 06:09 PM

easiest, cheapest way to stop a tiled garage roof from leaking?
its not a gaping hole, just weeping. possibly due to the snow recently, then thawing, but it is leaking none the less.

suggestions?

depends on what is wrong.

chances are the wieght of snow has dragged a tile out of place so a push with a big stick may sort it...... but then I know FA about roofing so feel free to ignore me.

screw fix. £10 buys you the biggest tarp they have


Meeerrrk - 11/2/09 at 06:21 PM

i did think about a tarp and some bricks!

anyone ever tried aquaseal?

I'm going to try it in a bit. My rented garage (flat) roof is leaking. Years worth of leak mould spring some small trees that have gone through the felt + bitumen. Take out the trees, bung in some aquaseal. Bingo (fingers crossed).

mines rented too, im going to try either aquaseal or thompsons roof seal tomorrow, before the car goes in.

cheers,

it poo

for tiled roof ,check all tiles are seated and replace crack tiles (temp seal cracked tiles with silicon!)

Flat roofs
rented tell the landlord it's up to him
private fit EPDM roof membrain ( or have our company do it (we give 20year G/tee on waterproof) mat'l should last 50 years though! just I'd be too old to fix any problems by then!


Meeerrrk - 11/2/09 at 08:19 PM

landlord isnt that fussed, plus its cheap rental (now i know why lol)

quite happy to put in a bit of graft myself to fix it.

the roof is almost flat (very slightly pitched) tiled, if i get a ladder and get up there will it be safe to walk on?!

are you sure its not frozen rain and seeping in under the tiles when it thaws?


Meeerrrk - 11/2/09 at 08:55 PM

could well be, its a good point


tomblyth - 11/2/09 at 09:21 PM

use a hen walk ! just in case! take some photos !

Provided the tiles are overlapping properly and do not have any individual faults, such as cracks they should be waterproof.
However, if a ridge tile has come loose or moved it could be that.
As someone else said the present weather conditions may be causing thawing condensation to drip down.


Meeerrrk - 11/2/09 at 09:32 PM

i think it must just be that, or at least i hope. hey, ill give it a look over and a water sealing, cant hurt can it


BenB - 11/2/09 at 09:40 PM

Trouble is if you rent a garage they tend to pass on any costs to you IE they replace the entire roof rather than just doing a local repair and then suddenly the rent goes up 100%

Costs me an arm and a leg already (£450 per quarter not including electricity).... (for a single garage....)


Meeerrrk - 11/2/09 at 10:09 PM

wowsers, i thought £40/pcm was enough!

like i say im happy to put a bit of DIY in, im sure it doesnt need a new roof or anything that drastic

i hear what you say though, i can imagine getting landlord to replace roof and i end up paying for it in the long run lol


blakep82 - 11/2/09 at 10:17 PM

tried bitumen paint on mine a few years ago. was rubbish. started peeling off in weeks, any time there's a strong wind now i end up with it all over my car... don't waste your money

Snow and cold weather do funny things to unheated areas. Check you don't have and ice dam at the lower edge of the roof, this causes the melting snow to push under the tiles or shingles and cause leaks further up the roof, quite common here in Canada usually in the spring when snow on the roof melts.

£3.41 a week for mine glad I dont live in the south

If it's tiled and nearly flat there might not be enough angle for the tiles to seal and water can go uphill by capillary action if the overlap on the tiles is not big enough.

been looking at it today and i think it is that. the roof isnt actually leaking rain water, it just seems to be "condensated" on the roof. Im going up on the roof on saturday to take off any moss etc which will hold water, i think my car will be ok in there; ive got a proper fitted outdoor 100% waterproof cover for it.

thanks,

Mark

this is a valid point & it could be a contributing factor, however it doesn't "leak" rain water, it just seems to be since all this snow & heavy frosts recently
