Michael Ledford And you know when setting the plies it lays better upside down. Was in a truck once “still dark “ walking over the barrels of burmastic. Some one but a barrel in with no lock ring along with lid not sitting flat. Well lid slid my leg went in up past my knee. Give me derbigum any day.

Union workers are useless

DIY Teacher and Kwiconnect Allan Wilson I was amazed by that also. later in the video he calls it a power broom. hope that helps.

Thanks Davey B

+Stephen Gallant who taught you how to roof ? vapor barriers are not " needed " or " required " or even recommended on metal decks , unless the building has serious thermal issues causing thermal shock on the substrate , such as buildings like auto garages that go from hot to cold a dozen times each day , as for drywall or " Densdeck" being needed that is also false , drywall & dens boards Are only required where a class A insurance fire rating is required , drywall & dens boards can be substituted for hardboard or fesco but are not required , and drywall & dens boards require full priming before application of cold process so not much incentive to use an inferior insulation unless the class A fire rating is required . As for walking on fresh plays get real , I'll bet I've sprayed on well over 100,000 squares of Tremco & Garland cold process roofs where 100% daily completion is mandatory , meaning workers MUST flash curbs & walls, set dumps & flash pipes , then gravel daily , the only reason to wait 30 days or longer is in the case of a Top Coat application vs gravel , and even then the wait time isn't due to possible bitumen displacement from foot traffic , that's just stupid , the wait time is so the solvent within the bitumen has a chance to " flash off " so as not to cause " Brown Out , which is discoloration of the top coat . This company did a text book installation with quality material & workmanship , you just wanted something negative to say , I'm a 32 year card holding journeyman roofer & waterproofer with local 149 Detroit & I find zero faults with this company's installation methods , nice work guys . On a side note , instead of sweeping & removing your rock using expensive labor look into industrial vacuuming services , the service we use sucks all gravel off any roof for $8 to $10 a square , and they get rid of the gravel themselves , on BUR tear offs they can clean over 200 square a day & on ballasted single plys about 100 sq per day , it's a massive labor saver not having to handle any rock before tear off .

+Michael Ledford well first the conditioning unit on the roof seen makes me believe that this is a heated building and a change of temperature causes condensation on the warmer side of the insulation.when isopolystyrene is exposed to moisture it breaks down prematurely so unless you're south far enough that its always hotter outside this is a recipe for trouble I'm from Canada and a Red Seat journey man Roofer but lol what do i know people can check this out for themselves at the crca site also what is going to happen to the main membrane of this roof when the iso breaks down on q deck without a solid leveling surface lol I've never seen this done ever

+Michael Ledford and p.s our tremor inspector requires a vapor barrier on any heated building with insulated roof for a material warranty but what do i know lol tremco site will confirm this maybe you should think about reading up on the product you use

Stephen Gallant​ No need for me to read up on Tremco specs because I've gotten over 50 perfect 10's , just because " your Tremco salesman " sells the building owner a vapor barrier so he gets a bigger commission does not mean vapor barriers are industry standard , because they are not , its 100% wasted cash putting a vapor barrier on metal decks not experiencing extreme thermal shock , any building with proper HVAC climate control keeps humidity at or under 30% , now explain exactly what 30% humidity is going to do in a heated building , acoustical metal deck ( holes in deck flues for sound absorption ) need vapor barriers , type A & type b metal decks do not require vapor barriers , are you even aware there are different metal deck types ?, me thinks your a 1st year apprentice or helper , surely not a journeyman or master such as myself because your statements show ignorance of the trade , just like your comments about needing drywall with the insulation , do you even know what products are needed for a factory mutual class A rating & when they are needed ? as a test of your knowledge explain factory mutual approved systems like Tremco , Garland , Siplast , Koppers etc to us all & we''ll take it from there . Every commercial & industrial roof system is a different animal , there are few hard nailed specs for any particular roof deck ,with exceptions to acoustical deck needing " Twinkies " & gypsum & Tecktum decks , system components vary greatly with building conditions & system needs , you sound like you have just recently started working in commercial & industrial roofing , I highly doubt you've completed the 3 years school needed to acquire a journeyman card & surely don't have 32 yrs as a journeyman , what's your local Tremco reps name anyway ? I'm currently being sought as an inspector for several agencies now that I'm retired & possibly know the man .

I'm in Michigan not far from.Canada so conditions are irrelevant , once again explain how condensation can accumulate in a HVAC building where there is no thermal shock , without thermal shock there is no possibility of condensation forming , these are basic issues dude . Since you claim to be a journeyman I'll explain thermal shock condensate to you in a different way , we all know a non insulated METAL expansion joint will leak like hell in some cases but not all , in the hot months & drip all over when it's not raining , why do you think every non insulated metal E joint don't leak in the hot months ? the answer is an insulated ceiling , or plenum ,.if heat is absorbed before it touches cold air condensate can't form , heated buildings decks are the temp of the building , the staggered inso separates hot interior air from cold exterior air , therefore thermal shock is impossible , except in cases where building interior temps have dramatic swings from cold to hot to cold from large doors opening &.closing constantly , like warehouses & auto garages , buildings like office &.schools have.zero use.for vapor barriers .

He's speaking Canadian English.

Have you ever worked on a reflective roof? I have. One crew decided to wear shorts and some of them ended up in the hospital with burns on their legs. Also, I have a background in the cold process roofing business dating to the 70's. You better make sure what chemicals are flashing off with the materials you are using. Cold process evaporates some interesting chemicals that are not compatible with human skin. Same story, crew without proper supervision wore shorts with a cold process coating and ended up with burns on their legs. Also, I don't know where you can put on a roof not secured to I-90. I never have. Almost every one uses Dade County, which is 90. Any school district, government job, or military will require this, as will most manufacturers warranties.
