Frequently Asked Questions
Q: Why is a professional roof inspection necessary?
A: A visual inspection from an untrained eye can miss roofing issues that are impossible to notice without extensive knowledge and the proper tools. For a far more comprehensive Inspection, we’re able to examine each individual layer of your roof system through roof core sampling, drone technology and more. With this level of detail, we can detect any signs of damage with ease, giving you a complete picture of your roof’s condition.
Q: How long does a commercial roof inspection take?
A: Most commercial roof inspections take between 1–3 hours, depending on the size, layout and complexity of your facility’s roof. We also take your business operations into account, scheduling inspections and working in a way that minimizes disruptions.
Q: What kind of technology can CentiMark use during inspections?
A: We use different types of drone technology to get a fast, clear view of your entire roof, perfect for large or multi-level buildings. Through thermal imaging cameras, angled drone views and 3D virtual site assessments, we are able to safely and accurately assess your roof’s condition and explore potential solutions.
Q: Can summer heat cause a commercial roof to leak?
A: Intense heat causes commercial roof membranes to expand, while the sudden drop of temperatures with summer rain storms cause the roof to contract. This expansion can pull away flashings from walls or crack the membrane. Once the next rain storm hits, water will have a direct path into your building.
Q: Is it better to inspect a commercial roof before or after a heatwave?
A: Both are beneficial, but a post-heat wave inspection is critical. Sustained high temperature can compromise sealants and adhesives. Inspecting your commercial roof after a period of intense heat ensures you are ready for the coming seasons.
Q: Can drought conditions affect a commercial roof?
A: Yes. Extended periods of heat and drought can accelerate membrane aging, dry out sealants, and increase thermal expansion and contraction. Over time, these conditions can weaken roofing materials and make the roof more vulnerable to leaks during future storms.
