Note: Notice that the screws backed out are near the roof edge where uplift is strong. Once they come loose the wind will more easily penetrate and inflate the space between the metal roofing and underlayment. The combined forces of uplift and inflation are more likely to tear panels off the roof than either force alone.

In areas designated high-wind, you would recommend installation of additional fasteners at proper locations. In normal wind areas you might make the same recommendation, or recommend re-tightening of fasteners on an annual basis. Or you might give your client a choice.

Flashing

This is inexpensive metal roofing commonly available at home depot. No Sidewall flashing is installed because sidewall flashing for this roofing material is not always commonly available at home depot. Its omission is a defect.

Cut Panels

Panels that have been cut should have the cut areas primed and painted to help prevent the development of corrosion.
