I will soon need to have my boiler replaced (21 years old) and one aspect of 
the job that was worrying me (£££) was the thought of someone having to go 
onto the roof to fit a flue plate and flue. I was expecting costs for 
scaffolding.
I have just been watching some guys doing a new boiler at my neighbours 
house and was amazed to see that they had taken some tiles out of the roof 
and were standing in the loft to fit the plate and the balanced flue.

I guess they would have had to cut the sarking felt. Would this be a problem 
longer term? Are there risks associated with this type of approach to 
fitting the flue. When my time comes to have a new balanced flue condensing 
boiler should I be considering insisting on doing the flue fitting from the 
outside?

Take pity on a Hoody.
They suffer from limited peripheral vision and must have difficulty walking 
with the crotch of their tracky bottoms at knee level.

no - assuming you dont have an incompetently laid roof that depends on
the felt to keep the water out

Unless it's old pantiles. These can let in rain when it's driven hard at 
the wrong angle.

Are you in a mid-terrace? If not, and you have a gable end, why not take the 
flue out there like we have http://www.thehewitts.eu/flue.jpg

My roof is almost a pyramid (short ridge of about 5 feet) - do I mean double 
hipped or something.

The roof is covered with "Interlocking  Double Pantiles" not sure of the 
make - been trying to identify them from using Google.

If the sarking is disturbed then how should it be returned to a functional 
state?
