we have had the 30 year old leaking wriggly tin roof replaced on our garage with 100 mm thick foam sandwiched plastic coated steel 8 mtr long sheets which should last at least 30 years .
It was done in December last year , for the first two months we had some condensation , due to the garage drying out . But from then on it's been as dry as a bone . we did also have the door frame replaced as this was also quite rotten .
Due to the rigidity of the sheets we didn't need to add extra roof supports but I guess that with your shed , if it is a big one you may need them as the panels are not exactly super light .
Getting the closing cappings done all round the edges , around the profile & at the back edge was very carefully done with shaped foam strips and 150 mm right angle metal skirts.
The rear end where it runs off into the gutter was plugged with the preformed foam strips , then the builders replicated the profile on some cardboard which they transferred to some UPVC strips then cut to shape with a jigsaw and super mastic glued them on in front of the foam strips to protect them from the weather & UV .
I sealed the concrete garage floor with 5 litres of Finigans concrete sealer using a sweeping brush to apply bit once it was dry to stop not only dust but any rising damp that may happen . We also used a pump up fence sprayer to spray the walls with a further 20 litres of the sealer on the inside of the walls as the external render is a bit suspect now it is 30 years old .
We are very satisfied with the job , it's been well done (All the joints were sealed with a 30 yr viable SIKA ( sp ?) non setting mastic .
It has stopped the frequent water logging of the garage which started to cause problems to our washer , dryer , the freezer and all my tools and metal lathe every time it drizzled let alone rained like it has done here recently .
