Rain in the forecast? Know your tarps!

December 27, 2011

Roofers can tell you about the pit that forms in their stomach when they have an open roof with a storm approaching.  If you’re a homeowner, or roofer, do you know which tarp is best for your application?

Most folks are familiar with your standard blue poly tarp.  Chances are you own one yourself!  They are made in a 8×8 weave with a 4.26 mil thickness and are good for short term weather-proofing needs.  They do not hold up well over the long haul or in windy conditions.

If you’re looking for something thicker and longer lasting, there are two other heavy duty options.  Green heavy duty tarps are made in a 14×14 weave with a 10-12 mil thickness.  This tighter weave and thickness makes for a stronger, longer lasting tarp.  Silver heavy duty tarps are the same weave and thickness as green tarps, but have a stronger UV protection to last longer outdoors.

If you’re looking for something to keep the rain out until you can get a contractor in to do repairs, our blue poly tarp pricing starts as low as 5.1¢ per square foot!  We stock all sizes from 12′ x 16′ up to 50′ x 50′


Enter and Leave Your Roof Hatch Safely!

December 15, 2011

Entering and leaving a roof hatch can sometimes be difficult if all you have to grab is the side or body of the roof hatch. Although it’s not code, a simple, inexpensive accessory is available for roof hatches to facilitate easy ingress and egress through the opening.

Roofmaster manufactures a Roof Hatch Grabber Bar. It mounts to all metal roof hatches to provide a safe means for workers to hold on to when entering/exiting through the hatch. It comes with all necessary hardware to mount it to the side of the hatch.

Construction is tubular galvanized steel with an exterior grade exterior-grade paint giving many years of rust-free service. The Grabber Bar fits all sizes of roof hatches.

Keep Your Roof Hatch Openings Safe!

December 9, 2011

Any opening in a roof deck like a roof hatch is a hazard to employees or contractors if left open. Proper protocol is to close the hatch after going up through it, but most times this is not done leaving a dangerous hazard for someone to fall through it. This is in violation of OSHA’s standard 29 CFR 1910.23 and 27 that requires compliance for safe ingress and egress through hatch openings in the roof.

An accessory item is now available to place a safety fence, or rail, around the hatch to prevent accidental falling through the opening. This Safety Guard Rail is clamped around the roof hatch thus eliminating any need for screws or bolts. This also protects the roof deck since nothing is mounted on the roof; it’s mounted on the hatch body itself. A chain is secured across the opening to the roof hatch opening on the safety rail. This system can be easily installed at the time the hatch is installed or years afterwards.

Construction is 1-5/8” OD tubular galvanized steel with an exterior grade powder-coat giving many years of rust-free service. Each safety system is size specific to the roof hatch size. Most typical sizes will fit roof hatch sizes like a 2’6″ x 2’6”, 2’6” x 3’0”, or 3’0″ x 3’0”. Other sizes also are available.

Having trouble spraying cold process materials?

December 2, 2011

With Winter right around the corner, you may be noticing that you’re not getting the same spray results as you were the last time you had your spray rig on the job.  “Material is the same, spray tips and spray bars and hoses are the same, it’s the same pump, it’s the same crew…something must be wrong with my pump!”  Before you take your rig in to get re-packed, have you thought about the effects of the weather on the viscosity of the materials you’re spraying?

During the summer months, when the sun is blazing and the nights never get “crisp”, your materials probably maintain a relatively viscous state, and you’re able to spray from the moment you step on the job until the day is done.  In winter, the cold can turn what once sprayed like water into a drum full of mud.  Your pump may initially prime with some effort, but before long will be sucking air and you’ll be scratching your head.

There are several alternatives to get you back up and running.  If you’re running a high volume job, the WarmMaster may be a job saver.  The WarmMaster is an in-line heat exchange unit that warms cold process material as it is pressure-pumped from your material pump to the roof. It eliminates the torching or overheating of material without thinning or diluting with solvents. The WarmMaster may be used with any air or hydraulically powered pump.

If you have smaller jobs, you can add Drum Heaters or Pail Heaters.  For larger 55 gallon drums, the Drum Heater comes with a 3″ wide strap and 6′ power cord. For prewarming cold process drums. For use on METAL drums ONLY! Place on bottom of OPEN drum for best heat transfer and to allow for expansion of material as it is warmed. There is also a Thermostat option for this Drum Heater that has a 50 degree F to 425 degree F temperature range.

There are also 5 gallon Pail Heaters, also available with a Thermostat.
