fascia and conservatory roofs come up better in wet weather , than when it is dry and sunny imo, esp when using tfr, as it does not dry out to quick, i myself have done them i pouring rain , both when customers have been in , and when out, they always say how good they look, a good set of gortex water proofs , and you stay dry, can highly recommend berghaus paclite for all year round use ,
and a good pair of water proof boots, i use brasher borgue gtx- very hard wearing.
