The bottom line: if you live in greater Vancouver, your roof takes a beating – and not just in the winter and fall, when rain and snow put your roof to the test. UV exposure, thermal expansion, and the occasional summer storm can all take a toll on your roofing – no matter whether your roof is shingled, flat, or metal.
So the question is: is your roof ready for a Vancouver summer? And what can you, the homeowner, do to make sure it is?
The Summer Stressors
The heat of the sun is harder on your roof than you may realize:
Though Vancouver’s sunshine is less intense than what you’d find in other areas of BC – such as the Okanagan – consistent exposure to UV rays can still age your roof faster than you might expect. Shingles may dry out, crack, or become brittle, reducing their effectiveness in protecting your home.
Thermal Expansion and Contraction
Temperature swings—especially warm days followed by cooler nights—can cause roofing materials to expand and contract. Over time, this repeated movement can create small cracks, loosen fasteners, or weaken seals. This is particularly important to remember if your roof is on the older side.
Sudden Summer Storms
Even in the dead of summer, Vancouver is no stranger to the occasional surprise downpour, If your roof has minor vulnerabilities—like missing shingles or clogged gutters (things that may not seem like a big issue when the sun is shining)—these quick, unexpected storms can truly ruin your summer, leading to leaks or water damage inside your home.
What Can You Do?
Before summer hits, it may be worth getting out and giving your roof a quick inspection. For this, we would highly recommend bringing in a professional with the proper safety equipment, training, and an expert eye. If you’re a hardcore DIY-er, however, here are some things you can do:
Start in Your Attic
Even a quick peek inside your attic can tell you a lot. Look for water stains, signs of mold, or daylight coming through where it shouldn’t. Your roof may need immediate attention.
Inspect Your Roof from the Ground
Look for curling shingles, patches of missing granules, moss growth, or anything that looks “off.” You don’t need to climb up—binoculars or even a drone can give you a clear view of your roof’s condition.
Clean Your Gutters and Downspouts.
Blocked gutters are a drainage nightmare. They can lead to water backing up under your shingles during a summer storm. Make sure downspouts are clear and directing water away from your foundation.
Trim Overhanging Branches
Trees provide shade, but branches that hang over your roof can cause damage in wind or drop debris that accelerates moss and algae growth. Summer is a great time to trim back foliage.
Schedule a Professional Roof Inspection
Even if your roof looks fine at a glance, a professional can spot problems early and recommend preventative measures. Look for RCABC-certified contractors (like us!) to ensure high standards and potential warranty benefits.
The Long-Term Payoff
It’s always better – and cheaper! – to maintain your roof than to repair it. If you can stay ahead of summer roof stressors, that could mean fewer emergency repairs and a longer overall lifespan for your roof. Don’t wait until you see water stains on your ceiling. A little preparation now can save a lot of money and stress later.
