Who We Are
Sky Products Ltd. has spent more than 15 years specializing in metal roof attachments and equipment. Snow Retention Warehouse is our online marketplace. It lets contractors, roofers, architects, commercial property managers and homeowners across Canada order commercial-grade products directly, with real-time stock and clear pricing.
Our mission: to protect people, buildings and property from the hazards of sliding snow and ice.
What We Do
We supply engineered, non-penetrating attachment systems for standing seam and exposed-fastener metal roofs. Because they clamp to the roof instead of piercing it, the panels stay intact.
Our product range includes:
- Snow retention systems: S-5!® ColorGard®, X-Gard™, pipe rails and pad-style snow guards (cleats)
- Solar mounting: PV brackets and solar attachment systems
- Rooftop utility attachments: mounts for HVAC units, walkways, signs and lighting
- Custom solutions: for projects that off-the-shelf parts don't fit
Every product is engineered and tested to hold up through Canadian winters for the life of your roof.

Frequently Asked Questions
What is Snow Retention Warehouse?
Snow Retention Warehouse is the online store of Sky Products Ltd., a family-owned company in Ajax, Ontario. It's Canada's largest stocking distributor of S-5!® snow guards and metal roof attachment systems.
Do you ship across Canada?
Yes. We ship to every province and territory, and because our stock is held in Canada, orders arrive duty-free.
What is a non-penetrating snow guard?
A non-penetrating snow guard clamps onto the raised seams of a standing seam metal roof. It never goes through the panel, so there are no holes, no leak points and no damage to the roof finish.
Why don't you recommend glue-on (adhesive) snow guards?
Modern metal roofs have slick, high-performance coatings that adhesives struggle to grip, so glue-on guards often fail under heavy snow. We recommend mechanically attached, non-penetrating clamps instead.
Will these products affect my metal roof warranty?
Because non-penetrating clamps don't pierce the panels, they're designed to help preserve your roof warranty. Always check your roofing manufacturer's warranty terms before installing.
Which roofs are your products compatible with?
Our systems fit standing seam and exposed-fastener metal roofs. If you're not sure which clamp suits your seam profile, our technical team can help.
Can you help calculate snow loads or provide engineered drawings?
Yes. We can provide site-specific snow load calculations and custom layouts. Stamped engineered drawings are available for a fee.
Can I mount solar panels or HVAC units without drilling into my roof?
Yes. S-5!® attachment systems let you mount solar panels, HVAC units, walkways, signs and lighting on standing seam roofs without penetrating the panels. We also carry solutions for exposed fastener roofs.
Do you sell to homeowners, or only to contractors?
Both. We supply homeowners, contractors, roofers, architects and commercial property managers.
