Flashing and roofing - what we check for

The main complaint the NHBC receive is to do with the roof and this is why we take the time to snag the outside in as much detail as inside.
HomeSnag are the only snagging company to be able to comprehensively inspect this area using our specialist telescopic camera which allows us to safely inspect areas otherwise out of reach of ladders. Examples include broken tiles, failing flat roof, broken verges and soffits. We even find that the ridge and hip tiles aren't fastened properly.
One area that is very commonly missed is sarking detail under lead flashing which should have a 75mm upstand because exposed walls will experience wind conditions driving the rain underneath (and underneath the cavity tray). Also, the mortar and sealed bond of the stepped or apron flashing is often very weak and will be only a matter of time before it dislodges.
