coming away and falling off. the builder & developer have gone bust and we have a 7 year architects certificate on the building she is saying it is not covered this cant be true but has anybody any ideas what i can do next
I stretch the wire from one end to the other and it does kill the moss. Zinc will also kill the moss. Both metals will leach and kill the moss Neither will leave a stain. I use copper because I could get the bare wire cheaper than I could buy the zinc flashing, but this was 20 years ago. Also the copper wire was less visible, but it does need to be replaced more often. I used a nail into the wood over the side of the roof and stretched the wire the full length, I put 3 strips on each side separated by equal distances.
Read the architects certificate and see what the stated coverages include. In commercial construction the architect is responsible for errors in the design or details they have provided only for a limited period of time. The contractor performing the work is normally responsible for faulty workmanship or materials again for a limited period of time. The roofing contractors frequently have an extended period of responsibility five years the shortest and sometimes extended to 20 or so year for a fee. A certificate of the roofing guarantee is normally provided for the owners use by the roofing contractor and the roofing material supplier. The standard guarantee other than a few select items such as roofing, waterproofing and caulking is one year. Your issue appears to be a workmanship and materials issue. If the builder & developer have gone bust, you probably have lost the responsible party, unless you can prove the issue results from a design error or detail and this issue is covered in the certificate.
No, this architect is not right. This is covered. Is the certificate from the RIBA? - if it is get in touch with them. You could go to go Citizens Advice Bureau or a solicitor if all else fails.
