metal roof shed condensation problem

miketheDIYman

Reroofed my large shed with metal tile-effect sheeting only to find that in frosty weather condensation forms on inside and drips down on tools and other contents.
Looking for a remedy that doesn't cost too much - could bring in spray foam ( closed cell )
people but a bit costly and job a bit small for these companies. Have seen a DIY spray foam
on line but you need to keep both cylinders of 2 part mix at warm temperature for good mix.
Wondering if anyone has tackled this problem with any success especially with loose insulation
that could be packed between rafters !

Have the same problem myself with a self assembled metal shed that I put up last summer, its only a 10ft x 12ft. Had to empty it out for the winter because everything was getting destroyed with the condensation. Didn't put and membrane down when I was putting in the foundation, should have put only found out afterwards. Had 2 choices, either raise up the shed onto wood and allow it to breathe that way, not an option for me. Instead I've put approx 8 ventilation grills ( with more to be installed) drilled with a hole saw and then cut out the rest with a grinder, also sealed the floor with a concrete sealer. So far so good but wont really know until later on in the year.

Hope this helps.

Did neither of yiz put felt under your sheeting?????

Cheapest way out of this: Sheets off, chicken-wire on, felt on, sheets back on.

I used "Alububble" under my metal roof last year and its brilliant. About 70 quid did 6x4m and it acts as insulation also.

This is the best way to go. It's not that hard of a job but well worth it.

Ever Build Water Seal. So far so good.

Let the floor dry, gave it a good sweep and literally poured in on and followed around with a paint brush.Gave it 2 coats, just to be sure.
