Should pipe boots be nailed down at the bottom?

Some might say yes and other no.IMO every exposed nail head is a potential liability.

Personally. I prefer my guys to use clips.A simple strip of coil stock about an inch wide fastened under the flashing,,then the remaining strip flip back and over the typically nailed area will secure the flashing and will eliminate the otherwise exposed fastener.You can do that on the plastic,aluminum and lead boots/stacks.

Basically its an apron clip.Its much more detailed and leaves no fasteners exposed.

I say nail them down. That way, when the insurance adjuster argues about paying for boots and vents when they're not directly damaged from the covered hazard, you can point to the nailed down portion as justification for having them paid for. :badgrin:

If you don't nail them down, in the later years when the roof gets older the bottoms will lift up and sometimes allow water to run or blow in under the flashing base. Nail Em down and silicone the nail heads!

Not if you use lead instead of that plastic crap

Lead is the preference,,,with pipe flashings such as the plastic or the aluminum ,,,the fastener (Fastened or not)(Clips or no clips) is the last thing IMO to fail with those types of flashings.What makes a plastic or aluminum flashing fail more times than not is the neo collar.Dry rot of the rubber from extreme exposure resulting in cracking and splitting around the pipe itself is where the product fails.

In Missouri our squirrels have an appetite for lead.The little goobers gnaw and chew the lead around the tops exposing the pipes and overtime will cause leaks.But I would much rather have a squirrel cause the leak than me being a cheap skate and trying to provide a 10 yr. workmanship warranty around a product that will fail in a matter of a couple years depending on the severity of summer time temps.

I really like Perma Boot,, A little pricey but looks really good.I can spend about $4 for a 2""-3" plastic flashing,,,$6 for an aluminum 2"-3"''$15 for a lead 2"-5" or $20 for a Perma Boot.

Anyway you look at it Lead or Perma Boot is a better investment.It makes more sense to me to provide a better product for the customer than pocket a few bucks per flashing.

I don't think any of the top 100 roofing companies in the United States can say they made millions by shaving cost using an inferior product like plastic or aluminum pipe flashings.

Maybe so, but around here they all use galvanized bases with neoprene rubber collars. When in Rome do as the romans do. None of the local supply houses even stock lead boots. You would have to pay more, special order in quanity, cut down pipes and then the squirrels will still chew them up. We have an extremely high squirrel population here.

Also, the lifting up of the bottoms when not nailed down occurs with the heater vents, etc. too. Are you going to change those to lead also? If not then you need to nail them down and silicone the heads!

We use rubber due to squirrel concerns. However, we install the rubber rain caps on top of every one installed essentially double booting. It is the UV rays from the sun that breaks down the rubber causing it to become brittle and crap. The rain caps shield the pipe boot from the sun extending the life to that of the shingles.

I guess you could always tell the homeowners to hit those collars with some ArmorAll a couple times a year to squeeze a few more years out of them.

Ice and water under it is never a bad idea as well. Helps seal the nail shank.

Agreed,,,I push Ice and Water around all openings.Pipes,vents,walls,chimneys,crickets,skylights etc but still not a fan of exposed fasteners. :D

Plumbing suppliers usually sell lead boots probably in all areas where not normally available from roofing suppliers (for what its worth).

Squirrels love lead! Roofers love to beat up other roofers who use neo's. Its right at $20.00 for a 4" lead boot in my area!

If you cemented around the hole in the decking (and on top of the underlayment), the boot probably will never leak regardless. I have seen entire tops of neo's missing on 14-16yr old roofs with no leaks because the installers cemented the pipe.
