When you go solar, you’re adding equipment to your roof that should last for 25+ years. You can’t afford to compromise your roof’s ability to handle harsh Albertan conditions, from winter snow to dozens of freeze-thaw cycles per year and, don’t forget, our signature freak hail storms. This is one area that too many homeowners gloss over when they’re comparing quotes. They study price-per-watt and panel brands, but not how those panels actually get attached to their home’s roof.
Here’s the uncomfortable truth: a cheap installer cuts corners, and the consequences may show up immediately, or down the line. So, before you sign anything, here are the four roof details that you should know when getting solar quotes in Alberta, and the exact question to ask each installer so you can enjoy your new solar system without leaks and other issues.
1. Mounting on a Roof That’s Already on Borrowed Time
The mistake is simple: installing a solar system on a roof that only has a few years of life left, without ever raising it as a concern. If your shingles need replacing in five or ten years, every panel has to come off and go back on again; and that removal-and-reinstall (known as Re-Re in the industry) can run you thousands of dollars on top of the new roof itself.
A good installer treats your roof’s remaining lifespan as part of the design conversation, not an afterthought. Because our engineers attend every site visit, we assess your roof’s age and condition before we design anything. If we think you should re-shingle first, we’ll tell you - even when it slows down our own timeline. We’d rather lose a few weeks than put a beautiful system on a roof that’s not going to last as long as your new solar system.
Ask during site visits or proposal walk-throughs: “Did you check how many years my roof has left, and what happens if I need to replace it after the panels are installed?”
2. Skipping Critter Guard
Solar panels create a warm, sheltered gap between the modules and your roof, and pigeons are very happy to move in if that space is left open. Even if your neighbourhood doesn’t usually have pigeons, they can migrate – we think they have learned to seek out unprotected solar systems. To avoid clogged gutters, noise, nesting debris, and an unpleasant mess on your beautiful roof, make sure all your solar quotes include critter guard!
We install critter guard as standard, everytime, to keep pigeons and other small animals from nesting under your solar system, so you’re not sharing your home with unwanted roof tenants, or dealing with animals living and… well, pooping, shedding and dying on your roof. It’s a small but crucial detail that protects the cleanliness, appearance, and long-term maintenance of your system.
Ask your installer: “Is critter guard included in my installation?”
3. Relying on Butyl Seal Only
Most solar mounts use a primary seal at the roof penetration. This usually comes from the butyl rubber seal on the underside of the mounting base plate. When the fastener is driven into the roof, the gasket compresses and expands into and around the penetration, creating a watertight seal at the same moment the hole is made.
That primary seal matters, but we don’t believe it should be the only line of defence between your home and Alberta weather. These seals can be affected over time by heat, cold, UV exposure, and freeze-thaw cycles. If an installer relies on the gasket alone, your waterproofing depends on one compressed seal continuing to perform for decades – no redundancy.
On our installations, every roof attachment also gets secondary protection: an anodized aluminum flashing installed over the talon and tucked underneath the shingle above it. That way, water and debris flow naturally down the roof just as they would if the solar mount weren’t there. The butyl gasket seals the penetration, and the flashing directs water away from it. It takes more time and care, but it gives your roof a layered approach to protection instead of relying on one seal alone. We explain this in more detail in our related blog, “How Many Holes Will Solar Panels Put in My Roof?”
Ask your installer: “What mounting equipment do you use to secure the solar panel racking system and does it have a single or dual seal?”
4. Placing Roof Boxes and Conduit all over Your Roof
Once the panels are up, the wiring has to get from the roof down to your electrical panel. The lazy way is to combine all the cables into a roof box somewhere beside the array, and run conduit across the surface of your roof and down your exterior walls - and frankly, it can just ruin the aesthetic of a beautiful home. Conduit across a roof also requires more exposed penetrations that can go wrong and can itself cause rubbing damage if not secured properly.
We run conduit through the attic wherever possible, keeping your roofline clean and your penetrations to a minimum. All our roof boxes are hidden underneath the solar array, and in the occasional case where we must run conduit across the roof (vaulted ceilings occasionally make it necessary), we keep it AS hidden as possible, as well as colour match the conduit to your roof and siding so it blends as seamlessly as we possible. Paired with all-black modules and hidden clamps, our goal is to provide a solar system that is intentionally designed to blend into your home, and not look bolted on as an afterthought.
Ask your installer: “How are you planning on taking the solar cables down to my electrical panel?”
The Thread Connecting All Four
None of these are bad luck or honest accidents. They’re corners cut to win on price, or so the installer can gain a higher margin. It’s the same pattern we wrote about in our piece on the 5 red flags to watch for when choosing a solar contractor: the cheapest quote can often hide the most expensive future headaches.
We limit our installation volume to around 25 systems a year, on purpose, so an engineer is involved in every design and every roof gets the attention it deserves. And because we validate our work at the one-year mark, and offer a 5 year zero-headache workmanship arranty, we’re still accountable long after the panels are installed.
