The Roof-Pro system was developed to support building services on flat roofs without traditionally constructed up-stands penetrating the waterproofing membrane and insulation. The cardinal design principles are orientated to achieve the primary objective of facilitating a future re-roofing program without decommissioning building ser-vices.

Free Standing Supporting Frames for Air Handling Units.

Traditional methods of supporting air handling units, duct runs and cable trays involve positioning steel stub columns, concrete plinths and paving slabs on the roof surface.

The drawbacks to the traditional methods are a lack of flexibility in the positioning of units, the need to water-proof all penetrations and the fact that the units must be decommissioned and removed from the roof in order to facilitate any future works such as upgrading insulation levels or recovering the roof with a waterproofing mem-brane.

Roof Pro systems do not penetrate the roof, therefore no

cold bridge occurs, no vibration or noise is transferred and there are no penetrations to waterproof.

When the time comes for a roof membrane to be re-placed or repaired, the individual legs of the support frames are removed allowing a roll of membrane to be laid. The leg is simply bolted back into position and the threaded leg is adjusted to take new membrane or insu-lation into account. Only basic hand tools are required to complete the job.

Inside this issue:

In Summary:

• No Penetration of the waterproofing layer.

• No transfer of vibra-tion or noise into the building.

• No “Cold Bridge” through the insulation layer.

• No decommissioning of units to carry out works on the roof.

• Frames can be posi-tioned as required.

Frequently Asked Questions.

Ducting, Pipe Runs and Penetrations through the Roof.

What is the maximum weight a Roof Pro system can carry?

Roof Pro frames are designed to transfer the weight of the unit directly into the roof deck through the large feet in the base of each frame. We calculate the number of feet required to spread that weight so that no one foot places more pressure onto the roof than the weight of an average man. In practice we can accommodate units of any weight, provided we can spread that weight through a number of feet. Recent projects in the Dublin Docklands have seen units of twelve tonnes being placed on Roof Pro frames.

How long does it take to install?

The Roof Pro frames arrive on site packaged with every single component required and a detailed mechanical drawing of each frame. Using simple hand tools typical frames can be bolted together in an hour or two.

Who installs the units?

The air handling unit installers or the building contractors operatives will normally install the units, as they will wish to position the frames to carry their AHU in precise locations. One novice contractor recently described it as being as simple as a Mechano kit, but on a bigger scale!

Who designs the frames?

Roof Pro employ structural and mechanical engineers who carefully ana-lyse the weight distribution in the unit to be supported. They then design a

frame to suit the unique requirements of that unit. Checks for stability in high wind, pressure exerted on the roof surface and correct distribution of weight are carried out for every frame supplied. Nothing is left to chance!

What does it cost?

If we are provided with a roof services layout drawing and weight / dimen-sions data on units to be supported, Moy Materials Ltd. will provide a quota-tion for the supply of a Roof Pro frame. Most frames can be supplied within 5 to 7 days. Photo Below : Stand alone access platforms and stairs may be cus-tom made.

The management of pipe runs , cable tray and ducting on the roof surface is equally as important as that of the larger condensers and chillers.

Pipe runs bedded upon paving slabs will also need to be removed to recover any roof.

To this end, Roof Pro provide a wide range of ductwork support frames ranging from lightweight threaded bar uprights with an adjustable cross bar in a “goal post” arrangement right up to heavy duty struts and cross beams designed to carry heavy duty steel pipe runs. In many cases a double cross bar is used so that numerous service runs can be accommodated with on ser-vice run slung below another.

Ultimately, these service conduits must enter the building and this is often the “Achilles Heel” of the roof design. To avoid leaks at these points Roof Pro manufacture the PP3 box in a range of different sizes.

These devices save time and money for the building contractor as they are available off the shelf and are simple to install. Thus cutting out the return

Roof Pro Plant Support Systems MOY MATERIALS LTD.

We believe that it is in the building owner’s interest to ask for Roof-Pro systems. By insisting on Roof-Pro systems with “3 Point Certification” the landlord can be assured that costs are controlled during future maintenance of the roof. Roof-Pro is a single source for all rooftop support needs from small pipes to 12 tonne chillers. Multi site landlords have reassurance that each site will be consistent reducing landlord input. Simply all issues regarding services support contact Moy Materi-als Ltd. and on site assistance will be afforded to third parties employed by the landlord or his tenants. The liabilities of inadequate installations with conse-quent decommissioning costs as well as inconven-ience are eliminated. A clear understanding of responsibility improves land-lord and tenant relations. The tenant follows the land-lord “tenant instruction” installing all rooftop mounted building services Consider also some of the additional costs of decom-missioning services; co-ordination, inconvenience, down time, risks, and damage.

The thermal image shown to the left shows an extractor fan operating on the roof of a major south Dublin shopping centre. As we can see no heat is lost from within the building . If a traditional “stub column” arrangement had been used, the architectural design team would need to take account of the “cold bridging” effect and specify a deeper layer of insulation, adding significant extra cost to the con-struction of the roof system.

3 Point Certification—Setting Quality Standards.

The Moy Materials Ltd. & Roof-Pro team of estimators, CAD technicians, engineers and site surveyors will co-ordinate with the project design team and then will de-cide a projects requirements providing a quotation with drawings and calculations. Our experienced field sales personnel are available to give close support with de-tailed information on why using Roof-Pro ensures the best installation. The sales manager will also collate cli-ent information and direct Roof-Pro support as required until project completion. We offer very short lead times on all standard stock “off the shelf” items. Non standard frames which are de-signed to suit specific units are usually available within 5 to 7 working days.

Building services supported on Roof-Pro with “3 Point Certification” are certified for stability safety and integrity of the waterproofing .

The Client Brief: HVAC plant was required on the roof of a building that was in use. Due to the nature of the building use (public meetings with a media presence) installation noise and disruption had to be kept to a minimum. In addition, the existing roof covering was due for upgrading – but not for some time, therefore the plant being installed would have to be removed to facilitate re-roofing in the future. The Solution: The Roof-Pro System of independent plant supports offered the specifiers the solution. There was no drilling into the roof, no disruption of the existing waterproofing and no interference with the building use beneath. In addition, when the roof is upgraded there will be no require-ment to temporarily remove the plant to facilitate re-roofing. The items on the Roof-Pro System represent a good cross section of typical roof mounted plant: • Units with Anti-Vibration Mounts. • Large air Handling Units. • Heavy Steel Pipes. • Cable Tray Runs. The Roof-Pro Design Team calculated the required number of supports and the requirement for each unit.
