Roofing Cement in a tube....

What do you use...I am not a roofer, not too much experiance up there, but a friend call me over to his mothers house to repair a leak...just needs some roofing cement. What is some good stuff out there? I know there are four thousand brands and types of caulk out there so I assume like caulk, some roofing cements work better then others.

Chimney flashings, top nailed shingles on ridge cap, vents, fans, etc. are examples of some kind of sealant that should be used.

To cover any exposed nails that are sometimes needed, & to seal counterflashings on brick chimneys, brick walls, etc. I have yet to see a residential roof without some type of sealant used.

A subcontractor that worked for me 12 years ago used a quart sized mechanics grease gun that he would recharge in a bucket of roof cement,

You could also take troublesome toms advise & insist no caulk is needed even though his profession is a siding that is known for overkill on caulk to hide thier messed up cuts & such.

I wasn't referring to any siding along the roof, although now that you mention it, why do you siding guys insist on putting a 3" coil trim along walls on a roof? How do you expect a roofer to tear a roof & get to the tins along the wall?

Justaroofer, come over here and I'll show you dozens of roofs with no caulk on them. I agree sometimes it's necessary but we always do our jobs planning on NOT having to use any caulk.

Ghost, where is the leak at? If it is in the shingles, you should use an asphalt product i.e. blackjack etc. If it's in a flashing, geocel or np1 are great products.

Sorry to hear you live in Idaho, i can just picture all the dozens of roofs in the state with no caulk. Now back to reality, there is definitely a need for caulk on some aspects of the job, and it's not to put a bandaid on a future problem or anything after the hack is long gone either. By the way, i have had very few callbacks on my jobs & have done probably a few thousand.

Not a big deal for anyone around here, so long story short, caulk is used where needed. Do you like to leave exposed nails on vents, ridge, etc.?

I was just going to say that. As for the argument, roof cement and caulk are two different beasts.

Any "repair" you make with roof cement or caulk is not a reliable repair. It might work, and if so it won't last long. Ever go to a job and see 10 colors of caulk on some flashing and it's STILL leaking? Yeah time for a new flashing job. Why postpone the inevitable, just do it right the first time.

For roofing repair?

Tar in a 10oz caulking tube works best for me.
Way faster than loading a caulkgun by hand.
Very neat and convenient...for me?
Worth the $3. or $4. bucks.

Agreed...a well layed out roof won't really need to be caulked anywhere (except in certain cases of protrusions).

Caulk (silicone type) and shingles don't go well together.

Give me good old fashion flashing cement anyday.

I've gone up on roofs with vent pipes that I sealed a decade and a half ago that still are holding up.

I either use Bulldog or Karnak.
Both are excellent.
Both get the job done.
Both can be counted on.

Hi JAR,

When you say "caulk", do you mean silicone type?

Yes, exposed nails should be covered, but with flashing cement
(when they can't be shingled over or when they have to be exposed).
