For vented attics, should you drill holes through/across the rafters on each side of the light? That way you don’t have a soffit vent to nowhere and a ridge vent for a blocked off section.
Is it possible for a roof with traditional ceramic shingles (clay tiles)? Everyone here uses that kind of tiles. What kind of shingles are on the video?
This is a bad example because this house does not have an attic. Almost all houses have attics. So I would have to clean out the insulation and construct walls in my attic and then insulate the outside of these walls that make the light channel.
@@scottrenwick3681 I have a vaulted ceiling but I still have an attic above the ceiling. Also I have seen houses with flat ceilings and they put in a light shaft to the roof. Google it, I tried to post a link but my comment got deleted.
The shingles are staggered by the roofing company that Installed the roof, when you install a skylight you’re removing existing shingles not cutting new staggers in. Water can get under shingles and all roofing materials that’s why you have underlayment.
Cutting a rafter that's in the way? Do exactly as they did it and 10 years down the road you are working with a building engineer to calculate rafter loads and having a bracing system designed since the structure has been compromised. Also, they are preventing proper venting and mould will grow fast enough that you'll be seeking information on reroofing... Don't ask why I tell you this...
@@rmnjmnz8133 it all depends on your house and situation. We went through the trouble of: 1) Doubling the left and right next rafters (if you really need to cut one...) we've used LVL and structural screws for this. 2) We were working with 8" rafters here. We used 2*6 lumber for top and bottom brancing. The idea is to let air pass through 2" seems a minimum in my mind... Your local building code might ask for something else tough... Bear in mind that cutting a rafter as they did affects structure and this asks for an engineer to make calculations and suggestions.
@@davidproulx4782 Yeah, i don't recommend cutting the rafter, it could affect the structure strength, but as i see they've a narrow space between rafters, it's a must for them, also i want to make a skylight just for the light scene not for venting.
The best practice for any project is to first check the regulations, laws, legality before performing any work on a home. I agree, should have stated this in the video. Worst case, unauthorized work can nuke your homes value.
Why should it leak any more than anything else that pierces your roof? Like a chimney or vent etc. I have 10 vents on my rood and they are flashed into the shingles. If these skylights are flashed properly, they won't leak unless they leak somewhere on the actual plastic seals of the skylight.
All that lore is pre- ice and water shield era skylights. If done right, you’re more likely to get a leak somewhere else than the skylight itself with modern installation.
