THE WORLD'S FIRST, PERMANENTLY INSTALLED, RECESSED, ROOFTOP WILDFIRE SPRINKLER SYSTEM

Designed to protect any and all
buildings from a wildfire ember attack

Wildfires are becoming more frequent and more destructive.Rainstorm Sprinklers are permanently installed, recessed into the roofline, and remain virtually invisible at all times. Designed for wildfire protection, they provide rooftop water coverage without seasonal installation or freezing concerns.

Our Founder is Richard (Rick) Walker a retired Engineer with more than 50 years of engineering, design, construction and innovation experience.Throughout his career he has developed practical lighting, energy, mechanical and electrical engineering solutions for residential, commercial and industrial building projects around the world.He created Rainstorm in response to the growing threat of a wildfire ember attack, with the goal of providing homeowners, architects and builders with a permanently installed supplemental layer of protection that complements FireSmart principles and modern wildfire-resistant building codes and practices.To learn more about Rick's background and career, please visit his LinkedIn profile (linked at the bottom of this page).

Rainstorm Sprinklers was founded with one simple goal:To develop a practical, permanently installed wildfire sprinkler system that homeowners can depend on when every minute counts.Unlike temporary roof sprinklers that must be installed during an emergency, Rainstorm is always ready to operate when needed.The system's piping is hidden inside the roof at all times, and the tiny, fixed sprinkler head requires no seasonal installation or removal, has no moving parts that require adjustment or routine maintenance and does not interfere with other roofing maintenance issues.Designed specifically to help reduce the risk from wind-driven embers, Rainstorm provides complete water coverage while allowing homeowners to focus on what matters most—their family's safety.Increasing wildfire activity has shown that many homes are lost long before flames arrive. Wind-blown embers can travel hundreds of metres, landing on roofs, in gutters and around vulnerable parts of a building. Rainstorm was developed to help address this growing risk.

Rainstorm sprinklers installed and tested
on the inventor's own home.

Rainstorm sprinklers are particularly suited for
homes located in wildfire-prone communities, including:New custom homes
Major renovations
City and rural properties
Lakefront homes
Mountain homes
Remote cabins

A dedicated water supply is requiredFor some homeowners, an above-ground swimming pool
can serve two purposes:Three seasons fun for the kids and family, plus a substantial built-in fire-fighting reservoir for wildfire protection.

Many recent fires have shown that wind-driven embers can threaten neighbourhoods well beyond the forest edge.
Homes within towns and cities are not immune when conditions
are severe.

If you're building a new home, or planning a renovation,
you really should consider a permanently installed wildfire sprinkler system, wherever you live !!!

This is an example of an ember fire-storm.

Typical roof installation showing fixed spray heads
positioned along the roof ridge.

Rainstorm uses fixed spray heads positioned at or near the highest points of the roof to provide effective water coverage across both roof slopes.It doesn't matter how many ridge lines or what angle roof(s) you have, or even what your roof is made from, we have a solution for you. Every home is different, which is why Rainstorm is designed to be adaptable to a wide variety of roof designs.Rainstorm can also provide added protection against fires originating from rooftop solar panel installations.

This is a short video that will introduce us, and help you understand what we can do for you...

WHY YOU NEED RAINSTORM

We have designed and built a fully developed, actual working prototype installation on a single family home, and the patent applications are pending in Canada, USA and Australia.We can work with you, your architect or your plumbing contractor to design a complete Rainstorm system tailored to your building.Rainstorm is ideal for new home construction but can also be retrofitted to many existing homes.

Planning Your Water and Hydro Supply

A wildfire sprinkler system is only as reliable as its water supply.For that reason, we recommend homeowners consider a dedicated backup system capable of operating independently of municipal services. Depending on the property, this may include:A swimming pool, orAn above or below ground water storage tank.A dedicated pump and backup electrical supply are recommended. During a major wildfire, municipal water pressure or electrical service may be reduced or unavailable. A self-contained water and power supply provides the greatest level of reliability.

You need both these items regardless whose
wildfire protection system you install.Take a moment to consider your own situation. and
read those words again.Even if you learn that from us, we have delivered a service to you.

Emergency roof installation during an approaching wildfire places homeowners at unnecessary risk.
Temporary rooftop sprinklers should never require homeowners to climb onto the roof during an emergency.Wildfire protection is most effective when it's planned years before it's needed—not hours before an evacuation.

The Rainstorm system consists of four main components:

✓ Roof Sprinkler Device✓ Sidewall Sprinkler Device✓ Recessed Wall Box + Distribution Header✓ Pre-Packaged Pump Station +
Distribution HeaderWe also have optional sidewall sprinklers available that protect
roof overhangs, wood decks, patios and covered walkways.Our products can all be customized to suit your exact requirements,
so be sure to contact us before ordering or if you have any
special requests.

Standard Rooftop Sprinkler Device

The standard sprinkler device is the heart of the Rainstorm system.It consists of several precision components designed to provide reliable rooftop water coverage while remaining virtually invisible after installation.Our basic standard device is 9" long and black in colour. It is dropped into the roof opening (preferably at or close to the peak) and secured in place, where it is connected to a PEX, Copper (or other) piping system that runs down through the building to where either the recessed wall box/header are located (they don't have to be mounted together), or to our pre-packaged pump station.

We offer 3 sprinkler body lengths, 9", 12" and 18", which can be used on roofs varying from flat to steeply sided slopes.

If you require metal exposed components
Natural brass upper caps and spray nozzles are currently under development. Contact us if you require them for your project.

Every sprinkler device comes with a weatherproofing gasket, upper and lower cylindrical caps, water feed tube and spray nozzle
(360 deg, 30ft diameter), two support brackets, spacers and
complete installation instructions.It is available in black or white and its body length can differ depending upon the exact material, slope and design of your roof.It is also available with different water spray radii, as well as for
180 deg sprays, if required. We even have a special sprinkler
for use above open cathedral ceilings.It is important to let us know what type of roof material and slope
(if any) you have, so that we can ensure that you get the
correct sprinkler device that you need.

Standard Sidewall Sprinkler Device

The Rainstorm Sidewall Sprinkler provides additional water coverage beneath roof overhangs and around vulnerable exterior areas such as wood decks, patios and covered walkways. It can be incorporated into a complete Rainstorm system and customized to suit the building’s design and surrounding property.Our sidewall sprinkler can be mounted on recessed or exposed piping, and either in pendant or sidewall configurations. Standard colours are black or white.Its clean, simple design simply disappears from view until needed.These are a couple of examples of them actually installed.

Recessed Wall Box

The recessed wall box provides a convenient connection point between your dedicated water supply and the rooftop
sprinkler system.If you have an existing exterior water storage system (like a swimming pool, hot tub or bladder/steel/plastic storage tank), you can
connect your water pump to it, to provide pressurized water
to the rooftop sprinklers.It comes with a 1" male, cam-lock fitting (which is good for up to
8 sprinkler heads).

4-Zone Distribution Header

The distribution header supplies water evenly to multiple sprinkler devices from a single incoming water line.Each sprinkler needs approximately 3 gpm at 30 psi pressure to operate properly. You can make up your own header, or purchase
our ready-made for fast on-site assembly.Ours works with the 1" recessed wall box, and can be located at
any place in the building, convenient for the sprinkler piping array.Each 1" header has a main 1" shut off valve, and four, 3/4" valved takeoffs, which can be split into two 1/2" pipes to supply two
rooftop sprinkler devices, plus a 3/4" takeoff to connect a
compressed air nipple to.

Pump Station with 4-Zone Distribution Header

Our complete pre-packaged pump station is available with a 4 zone (3/4" each) distribution header. You can make up your own pump and header system, or purchase ours ready made for fast on-site assembly.Ours works with a 1" incoming supply pipe and can be located at
any place in the building, convenient for the sprinkler piping
array. Its best use is if you simply want to "flip a switch" and leave the property on an evacuation order.It takes gravity-fed water from your swimming pool or storage tank, and pressurizes it to feed up to the rooftop sprinkler heads.
The pump runs on 120V, 1 ph. power.We always advise that a back-up, emergency power supply is
always available in case of hydro shut-down. This power switch-over can be done automatically in your absence, if you have any commercially available generator set.

The recessed wall box, distribution headers and pump station are
also available with 1 1/2" piping for 8 zones (up to 16 sprinkler heads), for larger projects.

We're still setting up the site for eCommerce transactions, so until it's ready, please contact us for alternate payment methods.

Why should I install wildfire sprinklers on my roof ???Good question. If you're really worried about losing your property to a wildfire, the best place to start thinking about a sprinkler install, is the roof.The roof is the largest area you have for flying embers to land on, and it's a known fact that red hot embers are the cause of over 95% of wildfire destruction to homes and other buildings.You never know when a natural (or man-made) fire is going to happen. Even if you live in a large city, it's not always possible for your fire department to reach or help you.Even if they can, they may cut-off both your water and electricity.If you have your own permanently installed, roof mounted sprinkler system, you are less dependent upon others, so you gain peace of mind knowing that you are protected.Do I need a permanently installed wildfire sprinkler system ???No you don't. You can have a system that you install when a wildfire is near, or when you receive an evacuation order. But you never know when that will be. Maybe you'll be busy at work, out of town or somewhere else, and you won't have time to get home and do your manual sprinkler install.Your home may be larger than normal, or 2 or 3 storeys high, or with an unusual roof shape or design. There are systems that clip onto your gutters, or that you can throw a string over the roof and pull a sprinkler up, and so on. However, you need to be sure that all parts of your roof will get wet, for any system to work properly.With a permanently installed system, it's one less thing you need to worry about. Again peace of mind, as well as adding value to your house, and maybe getting or reducing your insurance costs.

Here's a short video showing recessed rooftop sprinklers working on a house with gutters and a large deck. Everything is soaking wet in under 2 minutes.

Why are your sprinklers mounted near the roof ridge ???Because water naturally flows downhill.So by positioning the spray heads near the highest points of the roof, it allows water to flow across and down the roof surface, wetting it completely.We use fewer sprinkler heads than other high pressure systems mounted lower down that could cause damage to the roof and maybe enter the building through vents and openings.

Does my sprinkler system have to be recessed ???No. If you do choose to go with a permanently installed sprinkler system, there are other options that include surface mounted equipment. However, if you go with a non-recessed system, you are exposing piping and fittings to the elements, as well as making it more difficult (and expensive) to do your regular roofing maintenance.Exposed plastic piping is susceptible to weathering quickly, and exposed systems are generally uglier than Rainstorm Sprinkler's recessed system. We don't have sticky out thingies with metal whirly-gig bits and pieces, and there's nothing hanging down for the kids to trip over or the dog to chew up and destroy. Plus, the surface mounted piping systems, give more locations to trap leaves and twigs.Are Rainstorm Sprinklers made from metal ???No ¹. Rainstorm uses an additive material manufacturing (3D printing) process. This allows us to keep initial manufacturing costs down, plus (more importantly) gives us the capability of offering you custom shapes, sizes and colors to the tiny visible exposed part of the device that you see, and that does the actual work.Our exposed parts (the spray nozzle itself and the colored upper cap) are 3D printed from ABS, which is the same material that your roof/exhaust vents, plumbing stacks, drains and gutters are made from, totally weather and climate resistant.¹ However, we are presently experimenting with making our upper caps and spray nozzles from plain and painted brass, which will be available as a "special order" from customers that request metal exterior parts.

Cooling, you say ???Yes. Due to the process of "evaporation", by turning on your permanently installed sprinklers on hot Summer days, you will be able to wet your roof, and cool it down, thereby reducing the heat transmitted to the interior of your house.Bonus, built-in, low cost "air conditioning" !!!

Who designs and installs a Rainstorm system ???Great question. As the manufacturer, we work closely with homeowners, architects, designers, engineers and contractors to design and specify a complete Rainstorm wildfire protection system tailored to each project.One of the major advantages of the Rainstorm system is its installation and operation simplicity. No specialized installers are required. Once the design has been completed, the system can be installed quickly and easily by your own trusted plumbing contractor, helping to keep installation costs to a minimum.We provide the design expertise and the components. Your local plumbing contractor provides the installation.

Can I install the system myself ???Absolutely. Rainstorm specifically designed the system for ease of installation for either a contractor or a DIY enthusiast. When you buy a sprinkler from us, we provide you with a step-by-step installation manual (or you can email us for a copy right now).Our company founder built his own house (and installed eleven recessed sprinklers), in 2017, when he was only 72 years old, so if he can do it, most others can as well.For the more complex portions of the build (the plumbing headers and pump station), Rainstorm offers a ready-made package that you can buy and quickly/easily install.Can my sprinkler system be automated ???Yes it can. Our back-room boffins are working to get an optional remote control module up and running by early 2027. Initiially, it will include a camera that looks at your house, and an on/off switch for the pump, so that you can see that it's working. There are other manufacturers that provide exterior fire detection systems that sniff out products of combustion, and use IR to detect flames, or rapid rise in temperature, that may be connected to our package on an as required basis.

Plus there are name-brand generators that sense power failure and can self-start and run normally.At Rainstorm, we can work with you or your contractor to design these automated methods, just contact us and let us know what you're thinking about.

They can land and set fire to your roof, sometimes many hours before a fire reaches your property, or gets within range of an automated fire detection system. By then it could be too late.

How many recessed sprinkler heads do I need ???Good question. A lot depends on the shape, size, material and slope of your roof. Each "standard" sprinkler device has a spray radius of 15 ft, so it covers an area of about 700 sq.ft. You should allow for some water spray overlapping, so we recommend that (standard) sprinklers are spaced about 20 ft apart along the ridge.Now we do offer different spray configurations (like spray radius or quarter or half spray circles) so if in doubt, you or your contractor can send us a roof drawing with some exterior photographs, and we can help with the design.Do Rainstorm Sprinklers cause water damage ???Our sprinklers are mounted at (or near) the ridgeline of your roof, so they work just like rain. Hint.Rain water runs down the roof and does not enter into chimneys, roof/exhaust vents etc, which can cause damage to your home's interior. Many of the clip-on or high pressure fence/gutter sprinklers, spray water upwards, which makes it very easy for pressurized water to get under shingles or inside chimneys or roof/exhaust vents, so it could enter and damage your home.

Do I really need my own water supply and electrical generator for the system to work ???No, you don't. But these are the issues for you to think about.Each Rainstorm sprinkler uses about 3 gals of water a minute and works at a pressure of approximately 30 psi (similar to your car tires). Most homes, either on a city or well water system don't provide that kind of pressure.Think about standing on top of your roof with a garden hose. Yes it works, but not that well. Now stand on your roof with 4 or 5 garden hoses (assuming you have an average house roof size) all connected to the same wall hose bibb outlet. The water pressure and quantity is severely reduced, but yes, they (may) still work.At Rainstorm Sprinklers, we advocate for your own, separate water and hydro supplies, again for peace of mind, and independence from others, even if you don't choose our sprinkler system !!!Assuming you have an average sized roof with 4 or 5 sprinkler heads, you're looking at maybe 15 gpm of water. For 3 or 4 hours of protection, that’s maybe 4,000 gals of water in total.If you have an average swimming pool, likely it's around 15,000 gals. If not, maybe you can add an above ground pool, around 10,000 gals, so that your family can enjoy it all summer long. If not, it might be possible for you to add a couple of buried or above ground storage tanks in your basement or out back of the garage ???Or what's also feasible, is to store a couple of inflatable round bladder tanks (like the ones the fire departments use) inside a storage shed on the back patio, that you can pull out and fill with water at the start of the fire season. There are many alternates available.And don't forget a gas/diesel/propane gen-set, with lots of spare fuel, to keep your pump running for the time you need it.Something else to think about ???Every property owner needs to study their own situation in detail. Rainstorm Sprinklers can do a very specific job, exceptionally well. But it may only be a part of the wildfire protection you need.Do you have large forested areas surrounding your house, or car ports or deep overhangs on your house ??? Is your house "hardened" and does it comply with the "FireSmart" recommendations in your community ???Even if it is "FireSmarted", don't forget the embers.They can still fall on your roof !!!Any other questions ???Please ask by filling out our contact form below. We'll be happy to get back to you. Stay safe and be prepared with Rainstorm Sprinklers.
