What is Stormseal?

Designed for emergency responders, insurance builders and roofers, Stormseal is a polyethylene film that heat-shrinks to securely wrap a damaged roof or structure. Unlike tarpaulins, Stormseal stays put until permanent repairs can be made, resisting wind, rain and hail and preventing further damage.

This award-winning, Australian product, is reducing costs, hassle and distress for everyone involved in the process, including insurers, insurance builders, installers and homeowners.

Stormseal is also resistant to further storms including hail and winds up to 160km/h.

Months or more of protection

Stormseal can last over a year, giving you peace of mind until final repairs are made. See our extreme test in the Swiss Alps.

Todd & Jo Chapman, Berowra NSW, Homeowner

“I would conservatively estimate that the original damage has now increased by 50% because of the inadequacy of the tarps to stay in place whenever a storm occurs.

But now thanks to Stormseal I can relax and be patient as we are fully watertight and storm proof. Stormseal has taken away our anxiety as it gives us a genuine temporary roof until the fix time.” (more…)

Ryan Hage, Adelaide All-Trades (AAT)

“We pride ourselves on using cutting edge technology to rapidly make properties safe and restore clients’ peace of mind. As soon as I heard about Stormseal, I knew we should be using it. Stormseal is a fantastic product that we will use after storms and other damaging events. It’s especially good in difficult access situations. The best thing is that it stays put – we won’t have to go back to fix any more flapping or leaking tarps.”

Tom Dougherty, National Manager for HomeClaims Customer Support, Suncorp

“It’s a leading innovative product… what I have seen today is going to give us the ability to be able to do it once and do it properly and not have to re-attend which will be very efficient.”

The problem with tarps

Traditionally, storm-damaged properties are covered with tarpaulins, attached with ropes and sandbags.

These tarps inevitably slip, blow off or collapse as more bad weather hits.

Over the life of an insurance claim, which can be up to 12 months after a major weather event, tarps fail five times on average and often more than 10 times. This puts your staff, customers, equipment and reputation at risk.

This means you get called to reattach tarps – often in the middle of the night, and on weekends. The owners also become increasingly distressed and think you’re incompetent (and they aren’t afraid to tell you).

Why use Stormseal

Unlike tarps, Stormseal goes on once and stays put, resisting all weather and protecting your premises until permanent repairs are made.

The patented shrinking resins in the film wrap tightly to any roofline or damaged structure, requiring no ropes or sandbags. Heat application increases the strength of the film and creates a snug fit, without damaging any underlying materials.

Using Stormseal:

  • saves you the frustration of dealing with failing tarps over and over again
  • provides a better service to the homeowner
  • provides a more reliable more cost-effective service to the insurer
  • give you a point of differentiation over other insurance builders, which is great for winning new contracts
  • allows you spend more time on high-value jobs
  • allows you to project manage better

Case Studies

Abereum Roofing team increase 8-fold after Stormseal training

‘I teamed up with three other business partners to set up the roof division of Abereum Roofing & Plumbing a short while ago and it’s taken off, mostly thanks to Stormseal,’ says Mitchell Clarke.

‘We started with just two guys, but I’ve taken on another four already to meet the demand, and I’ll be putting eight more through the Stormseal installer training in the next month.

Stormseal weatherproofs buildings to prevent costly further damage

Berowra Hailstorm

In December 2018, a devastating hailstorm damaged 33,000 properties in northern Sydney. Berowra was one of the worst-hit suburbs. The storm damage bill rose from $75 million to $1 billion due repeated failures of tarps and other ‘make-safes’. When Stormseal was installed, residents were hugely relieved, with some homes still being protected 16 months later.

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.

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. 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.

Yes, it works on flat roofs for temporary water protection. It’s weldable with a system of joining the film so you can tailor fit it to just about anything.
