I'm going to replace 3 existing skylights with Velux. What is the best way to find the existing rough opening?

The interior openings for the skylights are drywall. If I just added an inch for the 1/2" on both sides, would that be the rough opening? My goal is to just replace the skylights and not have to re-frame and drywall the interior.

The current finished interior dimensions of the skylights are 2 @ 19" x 43" and 1 @ 19" x 19".

Answer: 
There is a five year warranty for the Solar Battery. Yes, the unit will open and close at night and on cloudy days, as well! At it's full capacity, it will store up power for up to 500 uses. I hope this is helpful. Thank you for choosing VELUX!

Rated 4.7 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Great skylight Framed the r.o. and it fit like a glove. Operation was very easy and the remotes work from the basement to the 3rd floor w/ no problem. August 8, 2016
Rated 5.0 out of 5.0 by Loved the 30% tax credit Considering the 30% tax credit this seemed like a very good value. Remote set up very easy other than the instructions should have mentioned the On/Off switch on the skylight that must be on to activate the remote before beginning. July 19, 2016
Rated 5.0 out of 5.0 by Cool Skylights! These skylights transformed the room. I can't imagine why anyone would install those opaque plastic bubbles when these are available. We had a contractor install and I don't think he had any problems except the instructions for the blinds were useless -- a few pictures -- had to scour the internet for videos. The blinds were not difficult to install once it was clear how to do so. These things close as soon as it starts raining and the remote control is very easy to use and basically auto-configures itself. There are lots of features with the control that we haven't explored. September 23, 2015
Rated 5.0 out of 5.0 by A 5-Star excellent review from a 40 year contractor/professional remodeler! Very well constructed sky light. Solid construction. Nothing is flimsy or cheap - all is high quality materials and fabrication. The product comes in a very durable cardboard box and the interior packaging is top quality which protects the skylight during shipment and loading it up on the roof for installation. Once installed it works flawlessly! The ease of the solar powered wireless remote control operation is amazing. It took no time syncing the remote to the unit. I must say the read out on the remote screen is state of the art. It looks expensive and quality when it mounts on the wall. The magnet securing the actual remote to the wall mounted cradle is clever. Best of all just today July 16, 2015 I did a walk through with the home owners (my clients) and both the husband and wife can not say enough of how pleased they are with the product or installation. As a contractor doing residential remodels for close to 40 years I absolutely would recommend this product. Only con is that I would suggest not to try this yourself. This is not a DIY project as there is too much involved with getting the opening and framing correct. July 16, 2015
Rated 4.0 out of 5.0 by Great product, looks great. It's a great looking skylight and works good too. It is a little loud opening and shutting but that's not too bad. The control panel is cool and looks nice on the wall. The item does not come with flashing which is necessary to install it. Not being aware of this we had to place a separate order and wait to have the installation completed which was a bit of a pain. June 4, 2014
Rated 3.0 out of 5.0 by Good shade, expensive product. I'm glad we got the shade for our skylight, it does diffuse the light and help to keep out added heat from the hot sun. It was not very easy to install, it could use better instructions. And it's pretty expensive for what it is. July 9, 2014
Rated 5.0 out of 5.0 by Solar power mades this one an easy option After much deliberation, on fixed or vented I am so glad I went wit the solar powered version. This makes my fifth skylight install, but my first that was done the correct way. I purchased the flashing kit, and Velux will back your installation for 10 years. Instructions were good, but youtube was very helpful. June 6, 2013
Rated 5.0 out of 5.0 by I love this skylight! I can't really talk about the ease of installation because my contractor did it. But I have had it for a year now and it doesn't leak. The remote control is very cool and I love how no electricity is required at all. Just cut a hole, install with flashing and patch the roof. It works like a charm and has totally transformed a dark bathroom. I am putting another one in my kitchen and a third in another dark bathroom. Very highly recommend this skylight. June 3, 2015
