Cutting hole in roof tomorrow morning

[clark_bailey]

Any last suggestions before I get the sawzall out in the morning to cut a hole in the roof. The roof is 8/12 pitch and shingled with asphalt shingles.

At least its asphalt mine is 8:12 but metal. Make sure youve got good footing and maybe tie yourself off to the other side if its more then a story. Mine is like 20'+ to the ground so I lay an extension ladder on the roof with a rope over the ridge to a tree or deck post and use that for footing.

Measure twice, cut once.

Then hammer to fit.

Use the base flashing as a template & cut the circle of shingles out before hand. You can go about 1/2" to 3/4" wider than outside of the base flashing (round or oval part, not the roof flanges). That way you have room to cut your wood deck out, won't kill the blade with the shingles, and the shingles will need very lil trimming. Remember, last course or two of shingles (depends where they are compared to the base flashing) under the lower area of the base flashing roof flange goes under the flange, rest of the shingles on sides & top go over the base flashing roof flange.

Ok , I'll bite!!

What are you cutting the hole in the roof for?????


Oh yea, almost forgot, Check the weather channel to see if/ when it is going to rain/ snow tomorrow
& how cold its going to be up on that roof. That way, you wont end up cutting a hole in your roof in the middle of a noreaster blizzard.

I would guess he is cutting hole for venting for stove.
I don't think Alabama gets much snow or Noreasters.

Has not snowed in about 15 years. Weather will be a frigid 45-50 F during the day. No rain until tomorrow night. I should have 12 hours to do the cut the hole for a HT chimney and install flashing. I will utilize a safety line due to the 32 foot elevation above the ground.

frigid says you hh:

Good luck with the install

Plumb bob off a nail to center the hole inside the attic fist to line things up. Then send the nail up through the roof and shingles to show you where the center is.

aw come on now it is not the fall that hurts it is that sudden stop at the end. lol
Another peal of wisdom it is easier to cut more off than it is to put some back. and when all else fails get a bigger hammer
