No valley boards


Recommended Posts

The roofer has started and says valley boards are not needed. We have 10 valleys in total all with GRP valley trays. All valleys have a double valley beam. 

 

So he placed the GRP valley straight over.

 

Is that going to be an issue and how?

Some of the better GRP valleys don’t need valley boards but check the manufacturers instructions. The issue sometimes is nothing to nail a batten to under the valley. You can use 9mm ply but the GRP valley has to be suitable and the ends of the battens need to be screwed and not nailed - again, read the MIs
