Transporting Single Ply Rolls On The Deck

August 30, 2011

Single ply roofing is currently one of the most popular methods of roofing for commercial applications.  Most material handling units, including conveyors and carts, were engineered with built-up roofing products in mind – namely tar, felt, gravel, etc.  These were (relatively) easy to get to the roof deck using hoists and ladders with hoisting wheels.  Rolls of single ply present a different challenge, as they come in lengths from 6′ up to 12′ and can weigh up to 800lbs, so it’s not as easy as piling rolls on a dolly or wheelbarrow and carting them to where they’re being installed.

Currently, we’ve heard stories of guys having to manually carry these rolls over the deck, which seems back-breaking!  We’ve also heard that our insulation carrier (with or without back wheels) can be used like an oversized dolly (forks are wide enough to balance the rolls).  Two other back-saving methods are to place the rolls on a 4-wheel trailer (and use the pins in the pin pockets to prevent roll-off) or to use our newly re-designed Single-Ply Roll Carrier.  All of these carts are offered with pneumatic or our Non-Flat Lite tires. Note: we recommend the rear-wheels for the insulation carrier.  Heavier loads are easier to move on the deck.

Our Single-Ply Roll Carrier is capable of carrying single-ply rolls up to 10 feet wide. It uses a mandrel that separates down into two (2) lightweight sections for easier handling and/or shipping. It breaks down for easy transportation anywhere (roof or ground); has large tires (18 x 8.50) that make it easy to roll on any deck by any size person; and it has an intermediate handle location to make it very easy to lift up rolls and maneuver them around the roof decks!

Material Distributors – Your Loaders Also Need Fall Protection!

August 18, 2011

Anchor systems must be used for any heights higher than 7’6” (until 9/16/2011). After 9/16, the height restriction drops to 6’0”. Local OSHA’s (like Cal/OSHA), may or may not use the Fed OSHA height requirements.  However, when facilities are on Indian land or Federal military bases, the federal OSHA regulations supersede local state OSHA and the height regulations in effect at-the-time will be in force.  In California, roofing supply vendors (deliveries) are subject to CA Title 8 3210 (Cal/OSHA uses general industry Standards due to the suppliers SIC code and no contractor’s license) which calls for fall protection trigger height at 7½ feet on all roofs.)

FIRST RULE: Never, ever, tie off your fall arrest kit to a conveyor!!!!! You will be cited immediately by OSHA.

Loaders have been asking if there is an alternate way to tie off & use their fall arrest systems differently than instructed by the manufacturers. Roofmaster has been granted permission to attach the shock-absorber (included in kit) to the hook end of the safety line then run the slider to the harness (see picture).

This gives the loader a little additional freedom to do the loading without having to continually move the slider all the time.

Distributers that load roofs are faced with some logistical problems that need to be addressed. First, who installs the roof-ridge anchor for the loading crew to use? If the distributor has to install it, the roofing contractor has to bear the responsibility of removing it and/or waterproofing it after the job is complete.  Distributors NOTE: Contact your legal counsel to determine liability issues if the anchor system you install for loading purposes is left on the job site.  Distributors & contractors can negotiate who will bear the cost of installing the anchor.
