Old Loft conversion done 40 years ago with Dorma. No Steel, all timber construction.

Loft room needed refurbishing, don't think it's ever been done since it was constructed so stripped the room back.

A few problems to sort outThere is a chunky timber ridge beam (in red on the uploaded drawing) sitting under the rafters, on top of the dorma 6x2 roof joists which has got a crack / split for a couple of meters.

What can I do to strengthen the ridge beam or is there no need to? The dorma roof joists appear to be taking the weight / load from the ridge beam? there are wedges under the ridge beam on ever other joist so it sits flush on them

The Dorma Joists are bolted to every other rafter.

i think it is flinch plates used to re-enforce timber beams, is it worth investing in these whilst its all exposed or something else? It's not possible to sister another timber to the beam as the joists are in the way.

Let's see a picture of the split.

Is there any evidence of a problem (sagging) or are you thinking better safe than sorry? Is there any sign it is progressing and getting worse

Lots of old beams have splits in them and are still plenty strong enough
 
Doesn't look like there is any issue, its just forward thinking really now the ceiling is down. The ridge beam looks to be the purlin reused from lower down where the dorma was built. The dorma roof joists (looking at video they may be 7x2) appear to be stopping any sagging

Looks like the type of splitting that is very common on old beams. I'd not be concerned but just a humble diyer and not an SE.

dormer.

Where along the length is the crack? If it's near an end, it's not going to be a problem. Even so, it could've been like that for years; if the roof is showing no signs of distress, leave alone.

The crack is quite clear in the photos, the blurred lighter beams in the foreground are not the ones in the question.

I'm not at the property till later in the week - the stills are from a video i took, but yes i thought you can see the beam cracks in the pictures - the other white lines are a couple of cables running along the beam! start off as finer cracks and get bigger towards the end

It's customary when surveying to not wear blinkers and not to solely focus on one thing, when the things around it may be relevant to any diagnosis.
 
From what you could see, you've no comment? That must be a first ;)
