Re-felting A Roof

Roofing in the rain is never much fun.

Luckily there's been a good team of us working on this roof and it's made the wet days go that little bit faster.

 The last couple of weeks we've been systematically stripping and re roofing a large roof in the village I grew up in. The house is a lovely old place, full of character and that character extends up into the roof!

The previous roofers (back in the '70s I'd guess) laid the felt over the battens - not your usual approach! All in all though the roof wasn't in a terrible state, we've had to add new valley boards to each valley and replace or repair a few rafters on each section of the roof before adding new felt and battens.

We've also been splicing the old fascia board and making new fancy barge board. It should all look pretty good when it's done.

Making Box gutters

This week I had to make up two sections of large box gutters to waterproof an area of a barn we're converting.

The roof used to run down into a wall with vertical cladding that had normal guttering at the bottom. This was fine when it was just a barn as the water could run down onto the floor and not cause any problems.
As we're now doing them up it need to be water proof. We stripped off the cladding and the first four or five runs of slates so we could see what we were working with.
I then started at the lowest point and made the first step. A 1.4m run of ply that had a good fall on it. I then worked my way back to the other end of the roof creating each 1.4m run of gutter with a 50mm step between each level Each bit has to be fully supported and built in such a way to take the lead.

 Bert the plumber then leaded these for me and we set about lapping the felt back over it to make it waterproof before we put the slates back on.

I've now got to reinstall the cladding and repair a section of oak frame that I exposed due to a high level of rot/woodworm on one joint.

Make Your Own Slate Rip

This was something I was meaning to post ages ago but forgot! I was stripping a section of roof before Christmas to add a new back gutter to a chimney when I realised I had forgotten my slate rip.

I managed to make a temporary one out of an old disposable hand saw. Cutting the to the side of the hanging hole on the saw to make a notch.

It's then just a case of slipping the "rip" between the slates and over the nail, hitting the handle downwards to pull the nail out (or snap the head off).

This doesn't last for too many slates, as the plastic on the handle can only take so many hits, but it meant that I could carry on working and strip an area big enough to carry on.

Anyone else made a temporary tool lately?

Rotten Roof Repairs

A bee's nest behind a bit of rotten fascia board is what started a larger-than-we-thought-job this week. The painters had been prepping some of fascia when they noticed how rotten a section of it was under a chimney. I went up, stripped off some of the slates and investigated.

Rotten fascia was hiding some deeper problems

The fascia and soffit were both weak with wet rot but as I took back the slates I could see that the wall plate and bottom end of the rafters were rotten as well. 

Not trying to sell a tool but the Fein Multimaster is amazing for this type of work

So I then started quite a major repair for this little bit of the roof. Firstly I removed all the rotten wood, cutting sections out. When I cut the fascia out I used the Fein Multimaster to cut it on a 45 degree angle so I could easily fix a new piece back in, This tool is incredible for doing this, it would be a lot harder by hand and cause more disruption to the roof.

some rooten timber around this chimney

I started by adding in a section of wall plate. I used oak as that is what the original was, I used a good sized half lap joint to make sure the two pieces were fixed together and bedded it on a layer of mortar. I then cut a rafter end with birds mouth and added it into the roof. I made sure it was long enough to sit on the first purlin up in the roof so it would be structural rather and fixed to another rafter and also to carry the soffit and fascia when I add that later. I decided to double this rafter up around the chimney as it will make the lead work easier at a later date.

New rafter added and a new section of wall plate half lapped in place

With all the structural work done I cut a new bit of soffit and fascia to fit. When adding wood like this it's essential that they are added at an angle so if/when  the wood shrinks it doesn't leave a big gap. I replaced more fascia that I had originally though as it was rotten quite far up. I then treated all the wood before I covered it back over.

The finished repair, ready for a bit of paint

Quite pleased with the repair but it took a lot of time and it's never fun playing with rotten timber!
