Invented by an experienced licensed builder, Stormseal is a lightweight but strong polymer film that heat-shrinks to cover a damaged structure. Unlike tarps, Stormseal stays put, resisting all weather until permanent repairs are made.

Award-winning Stormseal is made for emergency responders, government agencies, insurance companies and their contractors, and all other roofers or builders. It has been used to protect thousands of storm-damaged properties in Australia and around the world.

  • Installers are trained to complete a damage report on arrival at the worksite.
  • Stormseal film is cut and tailored on-site to fit the damaged structure.
  • Because Stormseal is much lighter than tarpaulins and requires no sandbags or ropes (removed easier and faster)
  • Attachment occurs at the perimeter of the damaged area, so installers spend less time on the roof, reducing risk and cost. 
  • Heat-shrinking increases the strength of the Stormseal film and fits it snugly to the structure, without harming underlying materials.
  • We regularly inspect all Stormseal installations for quality assurance.
  • Stormseal can be easily removed and reapplied for roof inspections when needed.

Stormseal is far more cost-effective than tarps. Tarps are cheaper to procure but they multiply claims costs manifold by causing further property damage when they frequently flap, tear, leak, collapse or flyaway. Labour costs ­are also greater for tarps because they require repeated replacement – 4 to 5 times on average, and up to 13 times – during the months it takes to process a damage claim.

Another cost of tarpaulins is loss of customer goodwill. Customers are traumatised as their home suffers further weather damage and the noise of flapping tarps keeps them awake at night. They experience extreme frustration when they have to telephone their insurer repeatedly to ask for failed tarps to be replaced. In contrast, Stormseal customers are very satisfied because they experience minimal disruption to their lives and have peace of mind knowing their home is secure.

We only sell to accredited contractors, pricing is based upon volumes purchased. Please get in touch with us to learn more.

Installers save time by using Stormseal. Tarp installation time includes the time taken to procure supplies of tarpaulin, sandbags and ropes for each job, as contractors generally don’t carry these on their trucks. Frequently, the first tarp purchased is the wrong size, which means a return trip to the hardware store.

Meanwhile, with a roll of film and complete toolbox already on their truck, the Stormseal installer has cut the film on-site to fit the job, and commenced attachment. One roll of Stormseal holds 200m2, or enough film for 10 average make-safe jobs. This equates to about two days’ work without stopping for further supplies.

When repeat visits to replace failed tarps are added to the account, it’s clear that as Stormseal resists all weather and stays put until permanent repairs can be made, it saves contractors vast amounts of time and cuts insurers’ costs dramatically.

We prioritise the safety of workers, residents and properties and discourage practices that increase risks and escalate costs. We’re proud of Stormseal’s excellent reputation and intend to maintain it. To ensure safety and quality, accountability is key. Our solution is a complete system of accredited installer training, specialist equipment, controlled ordering and performance tracking, so our quality assurance processes cover everything from manufacture to installation.

Only accredited installers can order Stormseal film and a toolkit containing everything needed for correct installation. Instead of relying on ropes, sandbags and ‘Hail Mary’s to hold a tarp in place (and when that fails, returning repeatedly to replace the tarp), Stormseal installers do the job once and do it right.

At Stormseal, poor performance means loss of accreditation for the installer. By contrast, in Australia, when a tarpaulin (almost inevitably) performs poorly and requires replacement, the installer is rewarded with an additional make-safe fee from the insurer. Insurers pass these additional costs on to policy holders as higher premiums. Premiums also rise as claims escalate due to additional property damage caused by flapping, leaking tarps.

Storm victims who suffer under tarps and customers hit with higher premiums are likely to seek a better alternative, i.e. an insurer who uses Stormseal to provide a superior customer experience and keep costs down. Our insistence on safety and cost-effective high quality is positively transforming the insurance repairs industry

Our installers mechanically fix all edges of the Stormseal film securely, often to the eaves of the structure. The risk of secondary damage on removal of the film is low, and if it occurs, the cost of replacing fascia boards or some roof tiles is negligible compared to the massive cost of internal damage to properties caused by flapping, leaking, flyaway tarpaulins.

Property damage is also caused by the sandbags and ropes used with tarps. Ropes are often tied to any available attachment point including gutter brackets, down-pipes, gas/water lines and fences. Under the load of wind or pooling rainwater on the tarp, the ropes’ attachment points are frequently damaged. Sandbags break down within six weeks of weather exposure and the sand escapes, filling gutters and valleys to create barriers that force water back into the roof cavity, causing more internal damage.

Stormseal minimises harm. Tarpaulins, ropes and sandbags frequently cause damage claims to multiply manifold. The superior choice is obvious.

No. We hold inventory and dispatch Stormseal film from our stock when an accredited installer places an order online through our customer portal. We have capacity to scale up film production to meet high demand following a severe weather event.

Yes, Stormseal can cover a full roof if damage is total. However, the product is more often used to cover partial roof damage, e.g. tree impact on one side, or fire damage contained to one area.

Yes, Stormseal can be used to cover partial roof damage, e.g. a damaged whirlybird, a section of broken tiles, or over skylights.

IAG has conducted hail testing on the product, please see the video here.

Wind tunnel testing has been conducted by CSR and by the HAAG wind tunnel test facility located in Dallas TX. See CSR wind video here.

Yes, the product can be used for walls, windows, ceilings, garage doors, asbestos removal.

Stormseal film is recyclable; it is not biodegradable. Stormseal film can be repurposed – unlike damaged tarpaulins which generally go to landfill.

Stormseal has two application methods;

Non-intrusive: Stormseal film is fitted to the perimeter of damaged area using external Stormseal brackets, fixed into existing sub-timber like rafters or battens. Typically the roof tile would require replacement.

Intrusive: Stormseal film is attached through roof tiles and or external facia/barge boards at every 1,500mm. In a 10m x 10m area (100m2 or ½ an average house roof) 26 mechanical fixings are required.

Unlike tarps, both Stormseal application methods cause minimal external damage and prevent internal damage by providing lasting, secure weatherproofing.

E.g. Intrusive application of Stormseal might require drilling through roof tiles at 1,500mm centers, with damage costing $14/tile for remove and replace. Considering when a tarp leaks, it can cost $1,500/m2 to restore the water damage inside the home.

Yes, Stormseal film is warranted for one year from the time of purchase. The installation guarantee depends on the individual Accredited Installer’s terms and conditions.

Yes, Stormseal film can be produced in many colours. Branding / logos can be printed on the film –minimum volumes apply.

Yes. An access area can be cut out of the film and then resealed. In every installation there’s a checklist sticker applied to the film. The checklist indicates claim number and installer number so you can track it down.

Yes, we work with several insurance carriers.

Yes. Accredited Stormseal installers are trained to complete a roof report before installing the film. If further assessment is required, contractors often cut inspection panels, in which case an accredited installer must remove and replace the Stormseal film. In every installation there’s a checklist sticker applied to the film. The checklist indicates claim number and installer number Similarly, insurers pay for tarps to be removed for roof inspections and replaced.

Stormseal is manufactured in Australia through several suppliers who can scale up quickly to meet demand. Stormseal is also focused on safety and quality with a commitment to ethical, sustainable, local production with zero-waste in manufacturing. There are also back up suppliers available in the USA and UK.
