I had a Allmet Granite ridge roof installed by DLD distributors of Courtland Ontario. The Allmet installation instructions call for a "tightly Closed" slide lap seam. The seams have a gaps upto a 1/4". They maintain this is acceptable. I do not think so. What are my options now?

The best reccomendation I could give would be to contact the manufacturer and ask them. Some systems are designed with nearly invisible seams, while others are perfectly fine with a less neat looking seam.
The main question is whether it is a cosmetic issue or a functional anti-leak issue.

From a legal standpoint, you have no way to get the installer to change the installation, as it was installed to the manufacturer's specifications.
From a functional standpoint, it sounds like Allmet is standing behind the installation, so you shouldn't have problems with it leaking or the wind causing damage.
From a cosmetic standpoint, you could take short metal-to-metal stitch screws that would pull the lapped panels together. This would reduce or eliminate the gap, but at the same time, you are putting exposed screws in a hidden fastened shingle.
If it was my roof, I would leave it as it is, resting assured that the manufacturer stands behind the work that was done.
You might ask the installer and Allmet to provide a written statement saying that it shouldn't be problematic in case problems arise in the future.
