News from a tin roof 20th September 2019

There’s a woodpecker laughing at me overhead. I’m using the wrong size drill bit, AND I’m trying to drill elm.

The Orchard Barn office/mobile home is taking shape. I’m perched on my sleeping platform above the office fixing fillets onto the elm rafters that snake around. Who in their right mind would use wobbly posts in their roof? Ms Woodpecker is right. These materials are a joke!

Yet there is much in my use of round wood elm that is sane and sound. At 4-5” diameter they maybe small but they are perfectly strong enough to support the tin roof panels. Roundwood is much stronger than its milled counterpart because its structural integrity hasn’t been compromised by a mill.

These elm poles have been cut from the orchard in which they are being used. We carried them yards from where they grew, debarked them with a draw knife, chose the straightest plane and repurposed them on the roof.

Simple? That is until you want to fix the battens. At this point I need to explain that the battens are preloved. Not so long back they held the slates on my parents’ stable block. It’s important to me to be incorporating something of their home into my new one.

Straight battens on a wobbly elm roof require packing to level them up a bit (understatement – thank-you Marcus for your patience). Previous roofs have wobbled up and down and accommodated shingles. This roof needs to be flatter for 3’ wide corrugated tin sheets.

Wobbly story. Short. We got half the roof fitted this week, and weather permitting the other half will go up next week.

Down on terra firma I stood back to admire the new roof which is both beautiful, organic AND undulates gorgeously in a way we could never have engineered. I had to laugh. Ms Woodpecker was right all along.
