I’m not saying I would stop using it, but if it’s already on why tear it off?

On almost all of the home around here the builders installed drip edge on the bottom edge but not on the rakes. They installed a starter shingle on the rakes.

It has become standard around here to rip off the drip edge on the eave edge and install new drip edge with an 1.5 inch face.

I brought this up for 2 reasons. If the drip edge is already there why should I add in the cost to replace it?

OR if installing gutter apron is better than drip edge maybe I should switch to gutter apron.

Many of the gutter installation I see around here have the gutter on a big angle for drainage. I think that would require custom made gutter apron or it would not extend into the gutter in some places.

if the edge is an unpainted copper and is in good condition i would absolutly say keep it but if its painted steel or aluminum its probably a good time to replace it

I disagree Ed. Those were the 100 year old roofs I was discussing above. We do alot of these type jobs, at least a couple each year, in Evanston, Oak Park and older parts of chicago.

Minimum slope for gutter is 1/4" per 10'. Typically we will pitch it greater than that however, and yes on long runs the end piece may need to be a custom flashing. We also don't like runs longer than 35' without a downspout.

I'll make some gutter apron if I have to, but a good steel wide face roof edge does work just as well. We use drip edge on everything and run starters on eaves and gables. The drip edge makes the edge stronger, but it also keeps the fascia on. lol

Never use Rollex aluminum roof edge. It is almost useless. It bends and bows very bad. I think I could make something much stronger with brake aluminum.

Do you guys still have alot of wood fascias or what?

Interloc

I'd say they are more cosmetic on gables unless it was a re-sheet.IMO

You can go 40 feet for each 2" x 3" Downspout according to SMACNA, so I would presume 80 feet for each 3" x 4" Oversized Downspout.

Always err on the side of caution ed. I too read Smacna's book a few years back. 35' seems to work a little bit better and on the average home doesn't cause comsmetic worries. Even though an over sized downspout is twice the size, I wouldn't double the run. 80' is a long run for garbage and crap to build up in the gutter.
