I didnt know you knew that system. :o


#3

I didn’t know you were an inspector. :shock:


#4

j/k
Ive done that kind of roofing before ind i did not like it. But hey Im lazy.


#5

acutally the inspector thing just came along.
but as far as spf goes.
ive been around that for awhile.
its been on the market down here bout 20 yr,
heavy for about 8 yrs.

the coatings have gotten alot bett in the last 5 yrs.

and the spray techniques are gettin alot better.
the sprayer for the company im watchin (tarheel roofing),
gets it damn near flat over bur/gravel.

its definately pricless education for me.

eyall later.
gweedo.

pretty


#7

what kind of system is it? and can some one give me a link to the the manufacture or an installation guide.

Polyurethane foam is produced by a chemical reaction of a polyol and an isocyanate, in the presence of catalysts and other additives. The result is a rigid plastic that expands during the curing process and becomes a seamless layer of closed cell foam.

The roofing system includes preparation of the substrate, as well as application of the foam and elastomeric coating. This coating produces a weather resistant surface that can be walked upon for normal maintenance.

What are 10 advantages of Polyurethane Spray Foam?
Versatile
Polyurethane foam can be applied to surfaces with irregular shapes and penetrations. Applications include tanks, pipes, cold storage rooms and flotation devices. It’s especially suited for roofing, as many applications can be made over the existing roof. This can eliminate the need for costly tear-off of the old roof.
Stops Leaks and is Weather Resistant
Polyurethane foams form monolithic, self-flashing surfaces which effectively seal against leaks. Further protection comes from the weather resistant, elastomeric coating applied over the foam. The foam can be sprayed with slope drains, facilitating water removal.
Simplifies and Reduces Roof Maintenance
A seamless layer of foam is fully adhered to the substrate–horizontal or vertical–and withstands high wind stresses.
Adheres To Most Surfaces
The applied polyurethane foam system usually requires no maintenance. If damaged, caulking is sufficient for repair in most cases.
Provides Superior Insulating Efficiency
Polyurethane foam is the most efficient form of thermal insulation available. The systems usually pay for themselves in 2 to 6 years in energy savings.
Reduces Building Movement
By placing the insulation on the outside, the foam system reduces building movement and thermal shock.
Lightweight
Complete polyurethane foam systems are typically many times lighter than tar and gravel roof systems. When applied to an existing roof, the loose ballast removed usually weighs more than the replacement foam system. This results in the new roof being lighter than the original.
UL Listed
Polythane Systems spray foam are listed under UL 790* (Class A over non-combustible decks)and UL 723* (Class B over combustable decks).
Asbestos and Formaldehyde Free
Our foams contain no asbestos or formaldehyde.
A Proven Roofing and Insulating System
SPF Roofing systems have been successfully applied for over 30 years.

NOTE: Polyurethane foam is an organic material and will burn if exposed to enough heat and oxygen. For interior building surfaces, building codes require an approved thermal barrier.

boy aaraon that was quite a bit of info…can you give me a link? i think i might have a roof that would be ideal for this. it is a tar & gravel. it has been repaired numerous times per year (not by myself). i did the most recent repair (which actually worked). i informed the building owner that it is way over due for a roof. he is getting nickel & dimed to death with repairs. but it is leased out to a bussiness and it doesnt seem that he will want to spend the money for a complete tear down. is it a more affordable sytem as opposed to full replacement? is it compatibale with a cold climate? what kind of eqip. would be needed?

You would need heated plural component proportioning equipment.
You would need to invest in crew education to apply it.
I tried to post a link, but the forum kept saying it was detecting spam, so I just copied and pasted from the web page.

polythane.com/library/index.htm

Try that.

you should have your own tv show…“this old roof”


#12

they’re all old…haha…you would never run out of things to talk about, that’s for sure.
