Thanks Bill, I am not worried about the rail warranty. My focus is to
provide roof access for maintenance or firefighters, so that is why we
extend the rail. The shingles can take a beating during any maintenance
procedure and the extended rails provide a place to put one's feet
without slipping. These are RS compliant multimode systems, (dc). I
could have thought this out differently, but the other options would
have cantilevered the rail and I did not feel comfortable doing that. Chris

Many times when we get close to the end of a 'rail run', mounting PVs,
when the rail's end is still far enough away from the second or third
from the last PV, we will measure exactly where the outside edge of
the last PV will land. We then undo 1 or 2 of the bolts attached to
feet, pull the rail away from the roof a few inches and cut it there
with a 6" cordless 'skilsaw' (clean cut and very little vibration
using carbide blade) . Because we use PLP P8 rail (formerly DPW) we
re-bolt rail to feet and secure the very last PV's edge with their
back of frame flange clamp, P/N P8-ECU. All this ends up either flush
with or inside the end of the rail/PV edge.
Does painting new or anodized aluminum qualify for the
tail-light warranty?

We have been painting mill finish aluminum flashings for one large
repeat customer, and I can tell you that it doesn't look great. I
strongly question the long-term efficacy of this practice. But the
customer is always right... so we do it despite our protests. I would
refuse for a one-off job. I only do it because we have a contract for
hundreds of homes and my bargaining position is not good.
How much rail is really exposed anyway? We use Unirac's pro style end
clamps the rails don't really stick out much anyway. Or use BoB panes
with black rails and clamps.

A customer has asked that I look into painting the exposed parts of
the anodized rails on their roof mounted system to more closely match
the shingles. (New construction, we did not know what the shingle
color was going to be, and I have to say, I did not ask). Has anyone
any experience with this? Thank you for any help. Chris
