Replacing Skylights - Who to Hire? (DC/MD/VA)

[Andrew S.]

We recently got a new roof put on and ever since, all 4 of our skylights have been leaking. They are old and were fogged up but they hadn't leaked a single time until we got the new roof put on. Roofer came back out and looked it over, sealed them with some type of clear water sealant, and said the flashing and everything looked good -- but they continue to leak and the leaks are getting worse with each storm.

Question: how do I find the right person to replace these skylights? Is this something a roofer normally does? A window company such as Thompson Creek, etc.? Not sure where to start on something like this and want to make sure it is done right (and as cost effective as possible). Suggestions appreciated!
