History of the Feltlayer

June 22, 2011

Ever wonder how something got started?  Let me tell you about the staple of hot roofing, the Feltlayer.

Hot asphalt had historically been applied by cotton mops.  After World War II, with the construction of larger buildings and wide open spaces, there was a machine developed in the Chicago area for applying asphalt and felt at the same time.  It was known as the Rix feltlayer and it was distributed by Aeroil Products out of Hackensack, NJ.

The only problem is that it really didn’t work.  Along comes Roofmaster’s founder, Deryl Yundt, who was Pacific Coast manager for Aeroil.  He took the original steel design and modified it to make it work.  This was in about 1951.  He manufactured it and sold it back to Aeroil, until his decision to start Roofmaster in 1952.  It became known as the Roofmaster Feltmaster.

It was pulled backward so the operator could see the ply marks on the felt and also observe the asphalt flow from the valve at the bottom so there were no voids in the asphalt between the sheets.  This was the feltlayer of choice for nearly 30 years.

Then along comes Peter van Dijk, who was from Holland.  He had an engineering firm design an aluminum feltlayer with the intention of exporting them to Europe.  Trouble was that the roofers in Europe had too much pride in their work to use a machine.  It was then that Peter hired Greg Clements, a soccer friend, to market his feltlayer in the U.S.

Greg did his job and basically took the market on the feltlayer.  Roofers liked it because it was half the weight of Roofmaster’s Feltmaster and had sealed lids, along with some other features that gave it an advantage.

With the recession of the early 80’s, Greg was let go by van Dijk, and was hired by Roofmaster.  Van Dijk also made the decision to trade his feltlayer rights to Garlock of Minneapolis.

Around 1992, Roofmaster decided to upgrade and re-engineer the aluminum feltlayer.  We went back to its original design engineer and had him update and improve on his original design.  That new design is the modern Universal Feltmaster, manufactured by Roofmaster.  The aluminum comes in as sheet, where it is manufactured in to product for shipment from Monterey Park, California.

It is available with our NonFlatLite tires and insulation.  It will work as a 36″ or metric unit by just changing a plug on the valve end.

All in all, a useful tool for those large flat roofs where you can “blow and go” with the Feltmaster!


OSHA Slide Guard Update: 3 Month “Phase-In”

June 17, 2011

OSHA has announced a 3 month “phase-in” for residential construction fall protection.  The reason for the delay is to ensure contractors have time to successfully come in to compliance with the new ruling.  From OSHA’s website:

The three month phase-in period runs June 16 – September 15, 2011. During this time, if the employer is in full compliance with the old directive (STD 03-00-001), OSHA will not issue citations, but will instead issue a hazard alert letter informing the employer of the feasible methods they can use to comply with OSHA’s fall protection standard or implement a written fall protection plan. If the employer’s practices do not meet the requirements set in the old directive, OSHA will issue appropriate citations.

So now you and your crews have an  additional 90 days to comply.  Hopefully this will give you and us time to fulfill your requirements for fall protection to comply with O.S.H.A.’s new standard.  As we all know, O.S.H.A. is a self funded agency.  They are funded by fines!

Western Roofing Expo 2011 Wrap-up

June 8, 2011

We had a great time at the Peppermill Resort in Reno for the WSRCA’s annual Western Roofing Expo in 2011.

We saw some old friends, met some new ones and had a great show.  With all the recent OSHA activity, there was a heavy presence on safety, and we brought along a Texas Hold ‘Um, the only unit that offers mobile fall protection for 4 workers.  Here’s a snapshot of it in our booth:

Also, we re-introduced the Lazer Wagon, which Derbigum announced is the only approved torch applicator for use with DerbiBrite Roof Membranes.

Leister Triac-S Tips

June 1, 2011

You probably know that the most popular Leister Triac-S tip is the 40mm wide slot nozzle.  But did you know that Leister offers a whole array of other tips?


The 20mm wide slot nozzle is great for detail work.  The angled 20mm nozzle with 60º bend and the 20mm nozzle with 90º bend are ideal for detail work in hard to reach places.  Leister also makes a 5mm “pencil tip” nozzle.

In the majority of our Triac gun sales, the customer orders the Triac-S gun with 40mm tip.  We also offer the Triac gun with a 20mm tip.  And if you’re looking for a Do-Everything option, our Triac-S Kit comes with both the 40mm and 20mm nozzles, an extra element, high quality single ply shears, a 1-3/4″ silicone roller, and a convertable weld seam tester.

Roofmaster is a Leister authorized sales and service dealer with 4 locations across the U.S.A. to serve you.
