If anyone is familiar with the North Atlantic weather conditions and Shetland’s “between weathers” phenomenon, then understand the intensity and stress it required to change the roof of the caravan. Not knowing when nor how the weather could change, it took true grit and courage to rip-off the only thin protection against rain and winds this caravan has had for close to a year.
Having insulated, rebuilt and paneled all the outside walls, the layer of aluminum roof was only being held on with a small strip of treated lumber. This small strip was holding down the 40mm overlay that was available from the old aluminum walling and, together with many tubes of mastic, it was only screwed down tight onto the upper part of the new walls. This upper part prepared the way for new rafters, or roof trusses, and had to be “unsealed” to change the roof.
So it was! The mastic weather-proofed parts were taken apart, skylights removed, and starting at the one gable end the rafters were laid in place. Eyes were often spying the horizon for weather changes, weather reports were eye-balled several times during a day and the work days were….very….very…long work days.
Simply speaking, old roof is removed, new rafters put into place, electrical wiring adjusted and inspected, Kingspan insulation between new rafters, treated plywood screwed on rafters, layer of roofing “gortex” stapled on plywood, slats fastened on covered plywood, some insulation put between slats that would lie just under metal roofing (prevents condensation and keeps the place quiet during hail or heavy rains) and finish it off with metal roofing. (So “simple” this wasn’t…just to save writing many paragraphs)
How long did this take? I don’t remember. Maybe a week or two? I do remember several 18 hour days with hardly any breaks. I do know that it was tough working and sometimes I had to tack down a strong plastic tarp material for rainy periods in between all work. Fortunately, I had a few friends spend some of their time to lend a hand. Great help, indeed!
After the roof was in stable condition, I grit my teeth and attacked the extension area. Same procedure as the rest of the exterior…Kingspan, gortex and paneling. Just this last week, I finally could fit the new front door.
Old aluminum roofing was recycled. It weighed in at 40kg and gave £16.
