Temporary Fix for a
Roof Leak in BC
What actually works to stop or slow a roof leak until a professional can assess it — and what to avoid. These are temporary measures only; a professional assessment is always the next step.
4 Temporary Fixes That Actually Work
These buy you time — not a permanent solution. Book a professional assessment as soon as possible.
Roofing tarps
A heavy-duty polyethylene tarp secured over the damaged area is the most effective temporary fix. Extend it past the ridge and secure with sandbags or weighted boards — never nails, which create new holes. A tarp can hold for days to weeks in BC weather.
Roof sealant / caulk
Roofing sealant applied to visible cracks, gaps around flashing, or lifted shingle edges can slow water entry temporarily. This is a short-term measure only — sealant degrades quickly and is not a permanent repair.
Roofing tape
Self-adhesive roofing tape (butyl or bitumen-based) can temporarily seal small cracks or gaps. Available at hardware stores. Not suitable for large areas or active leaks.
Bucket and towel containment
Inside the home, place buckets under drips and use towels to absorb water. If you see a ceiling bulge, carefully puncture it to drain in a controlled stream and prevent collapse.
What NOT to Do
Frequently Asked Questions
How long can a tarp fix last on a BC roof?
A properly secured heavy-duty tarp can last days to weeks in BC weather. It's a temporary measure to prevent further damage while you arrange a professional assessment and repair.
Can I go on my roof to apply a temporary fix?
Not during or immediately after rain — a wet roof is extremely dangerous. If you must access the roof, wait until it's dry and use proper safety equipment. Better to call a professional.
What's the next step after a temporary fix?
Book a professional assessment as soon as possible. We'll identify the source of the leak, advise on permanent repair options, and assess whether GoNano treatment can protect the rest of your roof from further deterioration.
Will my insurance cover temporary repairs?
Most BC home insurance policies cover reasonable temporary repairs to prevent further damage from an insured event. Keep all receipts and document everything with photos.
