Commercial Roofing Accessories

Downpipes

Downpipes are highly important but often overlooked. They are essential in draining rainwater away from the roof, down to the building’s drainage system.

There are three common downpipe issues found in commercial building:

1. Inadequate size – Existing downpipes may not be large enough to cope with the amount of water directed into them, thus causing overflow and potential leaks,
2. Insufficient quantity – When there are not enough downpipes installed, the box gutter is forced to overflow, again, potentially causing leaks, and
3. Blockages – Downpipes can be easily blocked by stray rubbish and debris.

Ventilation

Hurricane Vent

The most commonly installed industrial strength ventilator used on commercial roofs is the ‘Hurricane’ vent. Specifically designed for commercial and industrial application, it has the appearance of a large whirly bird.

Some benefits of Hurricane vents are:

• Remove pollutants thereby improving air quality
• Remove moisture build-up to improve humidity
• Remove heat build-up through natural, wind driven air cooling
• Increases movement of fresh air

Ridge Vent

Another type of ventilation system used on commercial roofs is the Ridge vent. It is installed at the peak of a sloped roof.

Ridge vents are effective at removing moisture and heat and drawing in fresh air to circulate around the roof space.

Translucent Sheeting or Skylights

Translucent sheeting is a great option if you want a durable, weather resistant roofing material that also allows sunlight in. It is often used in warehouses, sporting complexes, shopping centres, factories, etc. To learn more view our ebook here.

Gutter and Sump Guard

These steel ‘mesh’ guards protect commercial gutters and  sumps from becoming blocked by debris or hail. They are installed over gutters and sumps (or downpipe outlets), providing a barrier which allows water to flow through whilst preventing debris and hail to do so.  They are particularly useful on commercial sites (such as shopping centres) where birds may go through rubbish and leave litter on the roof where it can collect and cause sump blockages
