Types of Roof Leaks We Repair in Calgary

Our team is trained to diagnose and repair all types of residential and commercial roof leaks

Shingle Damage Leaks

Missing, cracked, or blown-off shingles from wind and hail—Calgary's most common leak cause. We match and replace damaged shingles with proper sealing.

Flashing Failures

Deteriorated or improperly installed flashing around chimneys, vents, skylights, and wall intersections. We remove and replace with new sealed flashing.

Age-Related Deterioration

Worn sealants, cracked caulking, and dried-out rubber boots around penetrations. We reseal or replace all deteriorated components.

Ice Dam Damage

Water forced under shingles by ice buildup at roof edges—common in Calgary winters. We repair damage and can install ice/water shield to prevent recurrence.

Flat Roof Leaks

Ponding water, membrane punctures, and seam failures on commercial and residential flat roofs. We repair TPO, EPDM, and modified bitumen systems.

Hail Storm Damage

Dented, cracked, or punctured roofing from Calgary's severe hail storms. We document damage for insurance and perform complete storm damage repairs.

Frequently Asked Questions

Common questions about roof leak repair in Calgary

How much does roof leak repair cost in Calgary?
Roof leak repair in Calgary typically costs $300-$800 for minor leaks (single point, few shingles), $800-$1,500 for moderate repairs (flashing, multiple areas), and $1,500-$3,500 for major repairs (large sections, decking damage). Emergency same-day service may cost 20-30% more. We provide free inspections and detailed quotes before starting any work.
How quickly can you fix a roof leak in Calgary?
We offer same-day emergency roof leak repair in Calgary for active leaks causing water damage. For non-emergency situations, we typically schedule inspections within 24-48 hours. Most repairs are completed in 2-6 hours depending on complexity. We're available 24/7 for urgent situations—call us anytime.
What are the most common causes of roof leaks in Calgary?
The most common causes of roof leaks in Calgary are: hail damage (Calgary sits in "Hail Alley"), damaged or missing shingles from wind, deteriorated flashing around chimneys and vents, ice dams from freeze-thaw cycles, cracked rubber boots around plumbing penetrations, and aged sealants. Calgary's extreme weather accelerates roof wear compared to milder climates.
Should I repair or replace my leaking roof?
Repair is usually the best choice if: the leak is isolated to one area, your roof is under 15 years old, and overall condition is good. Consider replacement if: you have multiple leaks in different areas, repair costs exceed 30% of replacement cost, or your roof is over 20 years old. We provide honest assessments and never recommend unnecessary replacement—our goal is the most cost-effective solution for your situation.
Does home insurance cover roof leak repairs in Calgary?
Most home insurance policies cover roof leak damage caused by sudden events like hail storms, wind damage, falling trees, or ice dam backup. Leaks from gradual wear and tear or lack of maintenance are typically not covered. After Calgary's frequent hail storms, many homeowners successfully claim roof repairs. CMP Roofing can document damage with photos and detailed reports to support your insurance claim.
How do I find where my roof is leaking?
Common signs of a roof leak include: water stains on ceilings or walls (brown/yellow discoloration), active dripping during rain, musty odors in attic, peeling paint, and visible damaged shingles. However, finding the exact entry point is tricky—water can travel along rafters and sheathing far from where it enters. Professional inspection with attic access is the most reliable way to locate leak sources.
Can you repair a roof leak in winter in Calgary?
Yes, we perform emergency roof leak repairs year-round in Calgary, including winter. While some permanent repairs work best above 5°C (for sealant adhesion), we can apply temporary emergency fixes in any weather to stop active leaks. We'll return in suitable conditions for permanent repair if needed. Winter repairs may cost 10-20% more due to challenging conditions.
Do you offer a warranty on roof leak repairs?
Yes, all our roof leak repairs come with a written workmanship warranty. If the same leak returns within the warranty period, we'll repair it at no additional cost. Warranty length varies by repair type—we'll explain coverage details before starting work. This is in addition to any manufacturer warranties on materials used.
