covertek 407 or thermakraft 215 for standard corrugate roof ? , old house has anyone used either ? a few roofers have told me not to use the bitumen based papers as they slowly fall apart . but i wonder about the synthetic products and if they will last the life of the roof .

i would go synthetic product. the only problem i've seen is UV damage. keep it covered.
Where did you get your corflute from? Looking for a heap myself for a greenhouse.

corflute is not good to use. it won't let moisture go through it and dry. it can be just another condensing surface just like the iron. its not going to absorb any water. probably a bit better than the iron but water will run down and sit on the timber. the shed probably tons of airflow and heat so it doesn't really hurt it anyway. but do it on a house and you will have rotting walls in no time.
