We have a timber conservatory which was repaired after the roof sprung a leak last year (the old timber glazing bar caps had gone soft). Otherwise, the conservatory is in excellent condition and the actual glazing rafters are all solid and dry. The roof is large (about 3.6m x 8m) and slopes away from the house at about 6 degrees (so quite shallow).
The company we hired to do the repair removed all the old glazing bar caps and polycarbonate panels and then used lengths of 75mm x 10mm timber (along with a lot of silicon sealant) in place of the old glazing bars caps to hold the panels back in place.
After a few months, the roof started to leak again so the company came out and added more silicon sealant. This has now failed again so the company have agreed to perform a further repair.
I suggested replacing the timber caps with a system like this:

I even offered to pay for materials. However, the company insist that it will be better to use flashband tape over their timber caps due to the shallow slope of the roof. My feeling is that they are attempting to bodge the repair again so that it lasts a couple more months until the warranty on the original repair expires. However, I am no roofer.
Can anyone comment on the use of flashband tape on polycarbonate roofs? Would the Vale Glazing bars work any better?
I'd really appreciate peoples thoughts as I have to get back to the glazing company tomorrow.
Cheers,
