This failed wall could have been prevented, Had they installed an appropriate wall flashing. This roof was installed by a licensed Arizona roofing contractor. These are cornner cutting methods that will cost you the consumer alot of money later on. This is not uncommon to see.

Incorrect wall detail fails
This next picture is about a 3 year old modified roof that has buckles and a failed membrane seam.
This is a preventable problem. This roof also installed by a licensed Arizona roofing contractor.
This is not to say all roofing contractors are bad it just shows the need for an independent roof inspection before and after the work is completed. In both cases this could have been prevented.

This is a failed membrane seam.
I have talked about the importance of roof inspections before. In this picture you will clearly see why. This roof was in failure before the solar panels were ever installed. The company who installed the solar panels may not or may have known this, but why risk losing the job because of a failing roof. Had this homeowner had a $150 roof insepection done prior to the solar panel installation they could have had the roof replaced and they would’nt have the problem they now have. They could have had this roof re-roofed for around $1000-$1250 depending upon the roofing system. But now they are looking at about $1700-$2200 if they can even find a roofing contractor to do it. Reason is the panels have to be removed and since roofers are not solar panel experts the risk damage to these very expensive panels. This picture is decieving believe me when I tell you you need to remove these panels before you can re-roof this.

This is a big roofing problem
