Properly installed QUALITY skylights don't leak. Just like properly
installed quality roofing.
I am nothing more than a professional wanna-be. I've never had a roof,
flashing, valley, window, skylight, chimney, or door leak. I read
authoritative info. I follow directions. That's the only difference
between a professional and a professional wanna-be.
read up on said project, that you can do just a good of job as a pro,
no matter what the job is?
I believe that is true...as a general statement. Given that the pro
has to do the job within a time frame and the home owner "pro" has all
the time he needs to be anal about the appearance and quality of the
Certain things yes, certain things no and certain things better.
In the same timeframe as a pro providing we are doing the
exact same work & detail, no.
You can read all you want on taping and mudding drywall
but it takes a lot of experience to do it like a pro.
I will not do half-assed good 'nuff, who'll ever know things.
There's a good enough possibility it will be done better than
a pro in SOME cases.
You need to know your skillset and ability to figure things out from
But the real question is what is a pro?
The Borg has "Pros".
Someone listed in the Yellow Pages that lists the service?
Someone who has been hacking for 10 years?
Velux are an excellent choice and they stand behind their warranties if
you have any problems with the window. Installation of the skylights
are most crucial. The instructions that come with the Velux units must
be followed to the letter to guarantee a leak free roof and the proper
Velux flashing kit must be used again following all instructions. You
can count on developing problems in about 15 years anyway no matter how
good the installation.
Are you going to install them or are you having them installed?
Anyway, I shingled an 18 yr old roof in the north northeast that had two
fixed Veluxs. There was some evidence of prior minor leaking. I very
carefully removed the rubber seals, head, foot and step flashing and
reused it. Used flashing tape under metal flashing, sealed all flashing nail
roofing cement. Sealed all old nail holes in flashing with roof cement.
That was about a year ago. Lots of heavy rain, wind, ice and snow in
that time. No runs, no drips, no errors.
So, if I can get 18 year old ones redone without leaks, surly new ones
can be leak free if installed correctly.
I got the skylight flashing tape installation procedure from:
Roofing with Asphalt Shingles
I've 5 Velux roof windows, some fixed, some movable. All installed over
15 yrs ago. No problems.
My only caution is to make sure that who ever installs yours reads AND
understands the installation instructions.

I'll add one point. Get the type that mount on a raised curb, not the
ones that mount (nearly) flush to the roof. The nearly flush ones are
less obtrusive looking from outside, but are much more prone to
leaking that the ones with raised and properly flashed curbs.
I put in Velux (18"X2") before a re-roof and the roofer botched-it
(too lazy to ask for or get a screwdriver to remove the sealed collar.
I took it apart and sealed all with urethane caulk after straightening
Velux is widely regarded as the best source for sklights. I'd get
either fixed ones or if you want them to open, get the electric
ones. If you go half way with the manual crank type, you'll wind up
not opening them because it's too much hassle.
