Roof Past Its Best? Repair or Replace?

[dishman]

Hello,

Exactly what the topic title says. I am obviously going to get a local roofer to do an actual inspection at some point, and get their view and cost it.

However I would appreciate any impartial comments as to whether it is probably best to replace the whole thing or if it just needs a good maintenance overhaul. (I am considering a side extension with a new roof section so it may make sense to replace it all anyway, but I would welcome views on its current condition)

It is the original 1930s roof, in plain rosemary tiles. It has no roof felt/membrane and the rosemary’s are mortared to the batons, some of which has come away inside (but still looks mostly intact).

As you can see one or two tiles are missing at the moment. A number have de-laminated or "blown" and a number of the hip and ridge tiles are in poor condition. (It is a hi-res image so you can zoom quite close)

Apart from that, it seems to be performing ok, fully watertight etc. This is the north side so is in the worst condition. The South side is in much better nick.

Any comments will be most appreciated.

The de-lamination problem is the sticking point as it is difficult to see the extent of the damage without lifting the tiles.

If there is visible evidence from the ground then you can guarantee that it will be 10 times worse on closer inspection.

All the other points are repairable and if i wasn't for the delamination issues then your roof may well have had a few decades worth, left in it.

I would be inclined to wait until the scaffold is up (side extension etc) and do it all in one hit.

Replace it. Any money spent on it now will be wasted and will only buy a few more years
