What is the best calking to use

m and h

How long can i expect caulk to last on a nail head around a pipe collar and on flashings. What is the best brand?

Grumpy

Any polyurethane will last EZ 10 years or longer. Some neoprene are rated for 30 years but I don't beleive it. Solar Seal or Vulkem are equally as good and top of the line.

Better than caulk, nail a clip down under the flashing so the nail is covered and bend it back over the flashing. The only place I face nail is the last ridge cap.

Each person has their own preference, I for one prefer Geocel or Lexell. Alot of ppl like the NP1 products which I am not a big fan of.

Location and weather can be huge factors, here in Birmingham, Alabama, we have such huge variations in weather with year round nearly 100% humidity that I just use what I am comfortable with and trust which is what I listed above.

I have used solar seal for over 15 years no problems no leaks. everyone uses something diffrent but there is a warranty if im not mistaken. Never a leak dating back 15 years when i was shingling. hope it helps. OH it has a 50 warranty. just remembered. sorry i trust it fully and have so since they came out with it and well it has not failed me yet. have used to in a repair situation to re seal the shingles with a very small bead. hope this helps its just what i have used and when selling thats all i would order. thats 10 years.

Caulk is important inside and outside a home.GE Silicone 2 is probably the best caulk on the souk. It is used to stop or minimize water infiltration immediately.

Thanks for all the help.

I use a locally manufactured product from Holdfast NZ, Ive never had a problem. Anywhere the mastic is exposed and critical to the weathertightness of the roof, I sprinkle granules over it, hides the mastic and also protects it from the high UV levels we have here.
I use neutral cure silicone for gutters, metal roofing etc.

Goecel Tripolymer 2300 or NP1 is all we use.

I really like solar seal. The stuff is pretty easy to work with, lasts at least 10 years from what I've seen, and just try to take the stuff off once it's cured.

NP1 lately has been so hard to use, most of the time not even coming out of the tube without breaking a caulk gun. A couple supply houses around here have even stopped carrying it.

I like Geocell products too but don't think that their sealant is as good as solar seal. I do use the roof cement they make though.
