Dear Help Line,
Could you please recommend the best product to specify when flashing a chimney that comes up through a roof we are installing of Galvalume steel roof sheeting. Also, with a 20" chimney at the eve of the house, should the roofing contractor build a cricket at the chimney or simply flash it straight across?
Lead Flashing is great stuff, but heard it was not compatible with Galvalume... True?
Thanks for your help!

I would suggest a cricket.
Obviously, there is more than one way to do things but my suggestion would be a custom-made flashing fabricated from coil or sheet stock which matches the roofing.
Separate the metal from the masonry with roofing felt, a thin sheet of rubber, or even roofing cement.
If possible, make a sawcut into the brick to receive the flashing. Bend the top of the flashing 90 degrees to go into the cut. Seal with a quality sealant.
