Sky lights

[Lane]

I am redoing my roof after 16 years. I have a bubble style skylight that was installed when the house was built and the original roof installed. Do I need to replace the skylight? The roofing company is suggesting that I do but they also install skylights!?! I have had no issue with my skylight but they are saying that given its age, it would be advisable to replace it with a flat skylight when I do the roof.

I would appreciate some advice on this issue if anyone can assist.

I would, YMMV

There was a very similar thread here a few weeks ago. If you google, you will find it. Personally, I think the flat skylights look a lot better than the old bubble type, especially from outside. So, that would be a factor in my decision. Also, it depends on who made them. If it's a top company and they are in great shape, it's one thing. If they are some cheaper brand, more failure prone, then it argues for replacement now. They can be replaced anytime, but it is a lot easier to when re-roofing. Go see what new Velux ones would cost. Also consider if you would like ones that will open. I have them with the motor option and love them.

Why did a new roof only last 16 years?

What is the purpose of the skylight?

If it's mainly for light, would a "solar tube" serve the purpose?

e.g.

I hear that they are cheaper and less prone to problems, but I have no personal experience with either. I'm just tossing it out there.

Thanks for that. The skylight is only for light and it seems fine. I have had no problems with it and this is why I am questioning the roofer when he says it requires replacing. I didn't want to unnecessarily replace it if the roofer is just looking for more money. I found one site that said they have a shelf life of approx. 20 years but another that said they could last forever.

The second web site is wrong. Plastic skylights die in the sun. All of them.

Since you're already having the roof done, the roofer should give you the best price since he'll already be up there. Note I said 'should'. Get another estimate to keep him honest. His price should be below the skylight-only price.

BTW, the roofer will probably put a disclaimer in his warranty due to the age of your skylight - at least he should if he knows what he's doing. Too many things could go wrong and you'd blame him for the leak.
