New roof #1 - I decided to replace the crap felt roof that came with the Summerhouse which was just nailed on. This one is heat bonded to the wooden roofing boards & I have been assured it should last 20+ years (assuming the Summerhouse lasts that long beneath it!). Guttering fixed on last night, just in time for the overnight rain.
New roof #2 - the workshop has been finished & is now dry & structurally complete. Just got to fit it out now!
