flue through roof - no ceiling hatch Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

The flue for my new boiler probably needs to go up through the roof. It is a single story extension with pitched roof. The heating firm who came to give a quote said it was a problem there being no access to the roof space, as there is no ceiling hatch. I'd have thought that he would need to remove a few tiles anyway and the roof space is too small to actually get in anyway. Does anyone know why a ceiling hatch would be required ?

How can they install the flue without accessing the loft space ? impossible.

Why is there no loft hatch ? concrete flat roof ?

Its a small extension about 5 feet wide (single story) with a very shallow pitched tile roof. By that I mean the outside wall is 5 feet from the original wall.

There would not enough space for even a small child in the loft space. I agree a hatch would be a useful for inspecting the condition of the roof or for checking for any insulation etc.

The roof is quite low as it is a single story (and quite a low one) so I assumed that it first be required to remove a few tiles and work from above (or below to make a hole in the ceiling). Its probably a few inches of roof space between the top of the ceiling and roof at that point, as it close to the eaves on an outside wall. Its probably 3 feet from the top of the where the boiler will be to the roof tiles.

There is currently a flue on the outside wall at that point but too low for the proposed new boiler.
