Hi,

My roof started leaking one week ago, and we asked the guy who fixed
the roof before and he can't find where the leak comes from (the guy is
pretty honest and nice, but he seems to only know how to install it,
doesn't know how to troubleshoot it).

Can somebody suggest what should I do, can you please recommend some
service that can help identify the problem then fix it? I am living in
Bellevue, WA area.

Thanks,
Min


Frequent problem areas are chimney flashing, vent stack flashing or any
flashing, etc. Other things might be anywhere on the roof where a nail or
staple is.

If YOU personally are able to go into the attic area, go up while it's
raining with a bright light. Go vertically above where it comes in and
hits the ceiling. Look for a water trail going up the roof pitch and
follow it. Water can run along underside of sheathing, along trusses,
wiring, anything.

Could be as simple as a staple/nail pop, stack boot flashing nails need a
dab of roofing cement. Could be chimney flashing is so bad it needs
replacement. Ya just gotta get up there and look.
