The large main skylight is leaking

I have taken off the midi ones in the past any body done a large one, is it doable on your own. I had the ladder up Sunday to look and the ladder slipped, I almost went with it.
Anybody got out through the skylight onto the roof that way. I have asked the local builder to lend me his mini scaffold, much safer.
Think I'm getting old.

Surely Kev you need to get on the roof to drop it in after applying tape/sealant

Nope, just pull it down as you step down.

Hi Paul, I've recently done mine.
I've got a set of very high industrial grade step ladder which I use for access to the roof.
All of the securing fasteners are removed / replaced from inside the van.
On previous small mini Heki's I have used both the tape type sealant as well as different types of semi liquid types, the problem I found with the tape type is when the temperatures are lower they are a right sod to get them to pull down nicely and some that come out of a tube don't necessarily stick well to the plastic of the vent.
Before I started this one I did loads of research and came to the conclusion the best product to use was a Sikaflex butyl one Sikaflex 710.
Very easy to use and is what most manufacturers use initially.

I have always used Hodgsons Seamseal cv John although as I've said only done the small Hekis not this large one.

Yes but getting the sealant on and positioning it correctly to get it seated in the aperture I though you had to be above it

Put a stepladder inside the MH and work through the hole from the inside.

morning all


i use this on my motorhome as well as for lots of other jobs and keep a tube in the van 

https://www.screwfix.com/p/dow-791-weatherproofing-siliconeevan-sealant-white-310ml/33876#product_additional_details_containers


when i first got my van 5 years ago i did all the joints on the roof and it is still there sealing as it should and as it is more flexible can handle the heat in portugal

 it tends to get used by others during the winter in portugal


it is designed for outside use  is very flexible and not the old smelly stuff and is available in different colors 

i always clean the joint with surgical spirit first

WTF is a buffet, the only ones I know are, as in a buffet lunch, or here in France they call a sideboard a buffet.
Wouldn't want to stand on either to re-seal a roof light though.

Kev, forgot you're a bit North aren't you.
I was aware you spoke a bit strange up that part of the country [smile] and that it gets worse the further North you go.
Didn't know about the variation in use of words though, sounds a bit s**t to me [wink][smile].

Yorkshireman Paul born and bred for generations

Anyway back to the thread, it was a chuffing disaster.

Got the skylight off but it was kanackered so had to get a new one and because the weather was turning bad I paid top price for one. I has some old silver screen material covering the aperture until I got the new one.

I got it fitted though fine and all good, thank heavens  because the mother of all storms is apparently on its way, hope its not as bad as they predict.

Chuffing disaster, skylight was knackered which I didn't know until I got it off

I sealed the hole with an old bit of silver screen and then had to drive to buy a new one, I paid top money too as Thirsday was a smashing day and I needed it fitting

Really awkward on your own it needs 2 really for the large skylight

New one is in now, forgot the photos that's all I've got

Your right Alan it maybe out tonight or it would have been but we have just taken the van to a local farmers barn,

hi all

a couple of day ago i washed the hobby van that i am doing up went inside the van and the floor was wet under the main skylight

i took the surround off inside and the water was coming in through the seal on the roof  of the skylight


on closer examination, i noticed the skylight had spacer between the skylight and the roof

i would have prefered to remove the skylight and re-seal but the weather being so rough yesterday  i decided to clean and dry the spacer and the roof removing all the old sealant and then cleaning with scotch brite and surgical spirit

i then masked the roof around 20mm from the skylight spacer and layed a nice thick bead of dow 691 silicone across the roof and up the spacer  then removed the masking and smoothed out the edge

it worked out so well i decided to do the edges of the other skylights and antenna

luckily yesterday it was a little sunny in the morning and warm enough for the silicone to be used i covered the skylights with some bits of tarp and bricks to keep the rain off that came in the afternoon even though silicone is not affected by rain once it starts to skin but rain can mark it so best to cover


i lightly washed the roof today and rinsed with plenty of water and all was  bone dry, i would have prefered to do it later in the year but needs must and all that

 i am already having to replace a bit of floor that has rotted in the middle of the floor because the inspection cap of the fresh water tank had been leaking every time the tank was filled

luckily it is in a small triangular area near the french bed and bathroom that i have already removed and prepared ready to have a ply panel later in the summer once the timber has fully dried out



keep warm
