Securing Roof Tiles and Insulation

Verb

Hi all; I’m interested in adding to the insulation in my loft. My dad has just done his using Thermal Wrap (Tin Foil Bubble Wrap) which looks and feels rather good.

The tiles in my loft are slate with no felt under it, so I can see and touch my roof tiles when in the loft. So before I do mine with the Thermal Wrap I would like to secure my tiles if possible as once the Thermal Wrap is up I wont be able to see if any damage has happened to the tiles, apart from across the street. I have read a few sites on the www and came across a product called Roof Bond. It’s a sprayed on product that is designed to bond together and secure the roof tiles. I understand that the problems that comes with this is that it can secure the tiles too much as to where there is no ventilation in the loft and condensation can build up. This being said I still want to do something and feel that what ever I use I would do it in strips rather than the whole surface, thus leaving some ventilation.

Does anyone know anything about this type of Roof Bond product or similar???
And where is the best place to purchase it???

I will be doing this myself and don’t want to be paying out for someone to come in and do it.

Thanks

Carl

Should be insulating between the ceiling joists not the rafters. Save your money on heating the loft space and lay 270mm of insulation between/over the joists instead (leaving gap around eaves)

If you use the thermawrap stuff over the rafters i'll give it a week before it's dripping in condensation. I suggest you get your Dad to go check his loft. There was someone on here with exactly that problem not long ago ..i told them to tear it down and it fixed the problem!
Why do you need to do anything to the tiles...leave them be.. the roof coatings and companies that apply them are a con.

The spray on stuff isn't DIYable and in any event it also provides insulation and you wouldn't normally insulate your roof the way your father has. The majority of ventilation required in your roofspace comes from the eaves BTW not gaps between tiles.

If you want to put something on your rafters tack a breather membrane up there under the rafters. The material is porous and lets the roof breathe but also provides some insulating capability as it traps a layer of air. It will keep out the dirt as well. The majority of your roof insulation comes from laying standard stuff between the top floor ceiling joists.

as above.
slates and tiles have been used for centuries with no problems. most/all piched roofs will only require some maintenance every 50/100 yrs or so.
insulate (to the maximum) the loft floor/joists not the actual roof rafters.

Won't there still be a condensation problem unless the loft is well ventilated?
