It's been just over 2 years now since our roof was repaired. Concrete tiles, traditional in this neck of the woods. The tile on our roof is a two-year only style (like a B-Body car), so it took a few months for the replacements to be sourced. Once the guys started, it only took around 3 weeks. All broken tiles were replaced, all mortar joints removed and re-applied (including ridges and hips) and then the entire roof was treated for moss & mould, then pressure washed and eventually re-coated - a better colour.
Originally a Spanish Orange, now we have a much nice "Grey Friars". We still get good comments about how much nicer it looks. At the time the cost seemed steep, but unless you're prepared to get off your butt and help, or DIY, it's a case of suck it up and pay the man.
I also had to replace the lower cedar boards and replace all the lead flashings - as they had shrunk and torn over the years due to poor installation when the house was built in 1983. The trend then was to only have a 2" upturn on the edges, and run in one piece. Now the code calls for minimum of 5" upturn and maximum of 6' in a run (converted roughly from metric)

The results are really noticeable. I waited for about 6 months after the worst part was repaired before lining the ceiling downstairs....just checking for any sign of leaks during our winter.
For the cost of around $14,000 here, I am more than happy with the job, as I no longer have any issues with the roof holding out the rain.
BEFORE:
Removed old wood burning fireplace....
DURING:
The Scaffold crew were a bit rough in places....
By supplying the lead flashing myself, I saved around $1,000 off the cost. Luckily at the time, I was repairing a machine at the factory where the stuff is made.
I still have those lovely "Chocolate Brown" fascia boards to re-paint in Grey Friars & gutters to replace down below. Lockdown saw me working at my parents house, and then the weather turned to poop after I had finished their place.
Concrete tiles are great for sound deadening in the rain and hail....steel long-run and steel tiles not so much. Depends on the framing construction also. Changing out a concrete tile roof to lighter weight steel or fake slates here means extra tie-down fixings required on the trusses etc, due to the added potential for roof-lift during high winds. Well, that's what the Council people say at least.
