    I live in a two story timber frame house and woke up this morning to find damp/wet patches on the internal walls of my sunroom and around the back door...
    Both these areas are south facing where the driving rain was coming from last night.

    Could anyone have any idea how the internal walls are wet as there is a 50mm cavity and then the membrane and OSB board? Very worried here
    Thanks in advance

    Photos outside and inside might help - something taken from a distance so that the overview can be obtained. Water very often travels so needn't be entering in the direct locality.

    Check if your guttering in clear of debris and check if the felt from the roof is falling into the gutter. Sometime the felt can get caught behind the gutter.

    Sure the soot and water shot all across the sitting room floor from the chimney where I am. Never seen it like that before....

    Quite possibly it was Santa on a test run though....

    My guess is tat the sun room is an addition which has not included an adequate lean-to flashing http://www.buildmagazine.org.nz/assets/PDF/Build-140-32-Design-Right-Tricky-lean-to-junctions.pdf

    is the sun room an extension, if so there probably isnt proper internal cavity DPCs
