If the system is not installed correctly it could lead to wind attachment problems, heat loss leading to condensation, water penetration, and have a detrimental effect on any Warranties.
Report on the quality of the installation

All customers like to see a clean and tidy finish to their building; roofs are always out of sight out of mind. However, poor quality could well lead to defects in the future and additional costs to the customer.
