A leaking roof never comes at a convenient timeāespecially in Albertaās unpredictable weather. Whether it’s a sudden storm, melting snow, or damaged shingles, water seeping into your home can quickly turn into major damage. But even if a professional canāt arrive right away, you can still take action to protect your property.
Hereās a step-by-step guide on how to temporarily stop a roof leak, minimize damage, and buy time until a roofing contractor arrives.
ā ļø Safety First: Before You Start
- Donāt climb on the roof during bad weather
- Use a stable ladder and safety harness if roof access is needed
- Turn off electricity in the affected area if thereās water near outlets or fixtures
- Wear non-slip shoes and work with a buddy if possible
š§ Step 1: Contain the Leak Inside
Before fixing the exterior, stop interior damage by managing the water flow.
- Place buckets or pots under dripping water
- Use plastic sheeting or tarps to protect furniture and flooring
- Poke a small hole in ceiling bulges caused by water buildup to let it drain safely
š§¼ Step 2: Locate the Source (If Possible)
If itās safe to inspect your attic or climb up, look for:
- Wet spots, water trails, or discolored insulation
- Cracked, curled, or missing shingles
- Damaged flashing near vents, chimneys, or skylights
- Leaks near valleys or roof penetrations
Note: Water can travel along beams before dripping downāso the visible leak may not be directly under the roof damage.
š ļø Step 3: Apply a Tarp Over the Leak
One of the fastest and most effective temporary fixes is using a heavy-duty roof tarp.
How to do it:
- Measure the damaged areaāadd at least 3 feet extra on all sides
- Lay the tarp over the leak, extending up the slope (not just covering the hole)
- Secure it with roofing nails, 2x4s, or duct tape (if itās dry and calm)
- Tuck the tarp under shingles if possible, to prevent wind lift
Important: Donāt staple into the roof deckāthis can make the leak worse.
š§ Step 4: Use Roofing Cement or Patch Products
For small holes or flashing damage:
- Apply roofing cement directly to the crack, seam, or gap
- Press down with a putty knife and smooth it out
- For extra strength, place roofing mesh or tape over the area and coat again
These products work best on dry surfaces, but some emergency sealants can be applied to wet roofs in a pinch.
š§° Step 5: Quick DIY Fixes for Specific Problems
- Leaking around a vent pipe? Use a plastic bag and duct tape to create a water barrier
- Missing shingle? Slide a flat sheet of metal flashing or even a plastic folder under adjacent shingles to block rain
- Cracked skylight? Cover with a clear plastic sheet and secure the edges tightly with tape or sealant
š Step 6: Call a Roofing Pro ASAP
Even if youāve slowed the leak, the job isnāt done. These are temporary solutions meant to last hours or daysānot weeks.
Contact a licensed roofing contractor in Alberta immediately to schedule a permanent repair. Send photos, describe the damage, and ask if further tarping or inspection is needed.
š§ Alberta-Specific Advice
Given Albertaās freeze-thaw cycles, even minor roof leaks can escalate fast. If moisture gets into your attic, it can:
- Freeze overnight and expand cracks
- Lead to mold, rot, and insulation damage
- Void your manufacturerās shingle warranty
Proactive patching and insulation checks are critical in winter and spring months.
Final Thoughts
When your roof starts leaking, every minute counts. Knowing how to patch the issue temporarily can protect your home, reduce interior damage, and give you peace of mind while waiting for professional help.
Just remember: a tarp and sealant arenāt permanent fixes. Schedule a full inspection and repair as soon as possible to prevent future leaks and preserve the life of your roof.
