Question 1

How do you detect roof leaks?

Accepted Answer

We use thermal imaging, electronic leak detection for flat roofs, visual inspection, moisture meters, and sometimes water testing. Different roof types require different approaches. Our methods locate leaks without damaging roofing materials.

Question 2

Can thermal imaging find roof leaks?

Accepted Answer

Yes, thermal imaging is highly effective for roof leak detection. Moisture-saturated insulation retains heat differently than dry materials. Evening scans when roofs cool show moisture areas clearly as temperature anomalies.

Question 3

What is electronic leak detection for roofs?

Accepted Answer

ELD uses electrical methods to find breaches in non-conductive roof membranes. Since water conducts electricity and membranes don't, applying current reveals exact locations where water has penetrated the waterproofing.

Question 4

How much does roof leak detection cost?

Accepted Answer

Roof leak detection starts around $300-$500 for residential roofs. Commercial and larger flat roofs are priced by square footage or time required. Detailed quotes are provided based on your specific roof situation.

Question 5

Why can't I find my roof leak myself?

Accepted Answer

Roof leaks often travel horizontally before showing inside. Water entering at one point may appear 10-20 feet away. Professional detection uses technology to trace water paths and find actual entry points, not just symptoms.

Question 6

Can you inspect steep residential roofs?

Accepted Answer

Yes, we inspect residential roofs using appropriate safety equipment. For very steep or dangerous roofs, drone-mounted thermal cameras provide comprehensive coverage without the risk of roof walking.

Question 7

What causes roof leaks?

Accepted Answer

Common causes include aging materials, damaged or missing shingles, failed flashing around penetrations, clogged gutters, ice dams, storm damage, improper installation, and deteriorated sealants. We identify both the leak and likely cause.

Question 8

Do you detect leaks in flat commercial roofs?

Accepted Answer

Yes, flat roof leak detection is a specialty service. We use thermal surveys, ELD testing, and moisture mapping to locate leaks in membrane roofing systems, often used on commercial buildings.

Question 9

Can roof leaks be intermittent?

Accepted Answer

Yes, some leaks only occur during heavy rain, wind-driven rain from certain directions, or when drains are partially blocked. If your leak is intermittent, describe the conditions when it appears.

Question 10

How does water travel in roof systems?

Accepted Answer

Water can travel along rafters, sheathing, and insulation before appearing inside. This horizontal movement means the interior water stain may be far from the actual roof penetration.

Question 11

What is a roof moisture survey?

Accepted Answer

A comprehensive assessment of moisture conditions throughout the roof system using thermal imaging, nuclear moisture meters, or capacitance meters. This identifies all wet areas, not just the leak point.

Question 12

Can you detect leaks around skylights?

Accepted Answer

Yes, skylights are common leak sources. We inspect flashing, seals, and curb conditions around skylights. Thermal imaging reveals moisture intrusion patterns around these roof penetrations.

Question 13

How long does roof leak detection take?

Accepted Answer

Simple residential roofs may take 1-2 hours. Large commercial roofs require longer surveys, potentially full days for comprehensive thermal or ELD surveys. We provide time estimates based on roof size and type.

Question 14

Will you need to go on my roof?

Accepted Answer

Inspection often requires roof access for detailed examination. We follow safety protocols including proper fall protection. For roofs that cannot be safely walked, we use drone-mounted cameras.

Question 15

Can old roof penetrations cause leaks?

Accepted Answer

Yes, abandoned penetrations from previous HVAC equipment, antennas, or other installations are leak sources if not properly sealed. We check all penetrations during roof inspection.

Question 16

What should I do before roof leak inspection?

Accepted Answer

Note where interior water appears and under what weather conditions. Don't move ceiling tiles or materials that might disturb water patterns. Have roof access available. Share any previous roof work history.

Question 17

Can you find multiple roof leaks?

Accepted Answer

Yes, our systematic inspection identifies all leak sources. Roofs often have multiple deterioration points. Comprehensive detection reveals all problems for efficient repair planning.

Question 18

Is roof leak detection destructive?

Accepted Answer

Our methods are non-destructive. Thermal imaging, visual inspection, and most electronic testing don't damage roofing. Core sampling for moisture testing removes minimal material if required.

Question 19

Can gutters cause roof leaks?

Accepted Answer

Clogged or damaged gutters cause water backup that can infiltrate under roofing. Ice dams form when gutters freeze. We inspect gutter systems as part of comprehensive roof leak assessment.

Question 20

Do you inspect roof valleys?

Accepted Answer

Yes, valleys where roof planes meet are high-risk leak areas. We pay special attention to valley flashing, debris accumulation, and shingle conditions in these critical areas.

Question 21

Can roof leaks cause structural damage?

Accepted Answer

Yes, persistent roof leaks damage sheathing, rafters, and trusses through rot and deterioration. Early detection prevents minor leaks from causing major structural problems.

Question 22

What is infrared roof scanning?

Accepted Answer

Infrared (thermal) scanning detects temperature differences indicating moisture in roof systems. Best performed in evening when wet areas retain heat differently than dry materials.

Question 23

How do ice dams cause roof leaks?

Accepted Answer

Ice dams block drainage and force water under shingles. Water then leaks through the roof deck. We identify ice dam damage and advise on prevention through improved attic ventilation and insulation.

Question 24

Can you detect leaks under rooftop equipment?

Accepted Answer

Yes, HVAC units, solar panels, and other rooftop equipment often cause leaks from improper installation or failed seals. We inspect around all roof penetrations and equipment mounts.

Question 25

Do you provide reports for roofers?

Accepted Answer

Yes, our detailed reports with leak locations and thermal images help roofing contractors target repairs efficiently. This often reduces repair costs by eliminating guesswork.

Question 26

What areas of BC do you serve for roof leak detection?

Accepted Answer

We provide roof leak detection throughout Metro Vancouver and across BC. We service residential, commercial, and industrial buildings. Travel fees may apply for remote locations.

Question 27

How soon after rain can you inspect?

Accepted Answer

Inspection can occur any time, but immediately after rain may show active water paths. Thermal imaging is best performed when the roof has dried but wet areas retain thermal signatures - typically 12-24 hours post-rain.

Question 28

Should I repair or replace my roof after leak detection?

Accepted Answer

Detection results help inform this decision. Limited, localized damage often justifies repair. Widespread moisture or multiple leak points may indicate replacement is more cost-effective.

Question 29

Can roof material affect detection methods?

Accepted Answer

Yes, different roofing types (shingles, metal, membrane, tile) require adjusted techniques. Our technicians are experienced with all common roofing systems used in BC construction.

Question 30

How do I schedule roof leak detection?

Accepted Answer

Contact us at 604-239-9934 or info@Leak.ca. Describe your roof type, where leaks appear inside, and weather conditions that trigger leaking. We'll recommend appropriate detection methods.
