Built-Up Roofing (BUR) systems are composed of multiple layers of roofing felt or fabric, alternated with asphalt and topped with a protective surfacing. These roofs are durable but can be vulnerable to hail damage, which happens when hailstones strike the surface with enough force to cause dents, cracks, or even punctures in the asphalt layers. Hail can lead to surface granule loss, exposing the roof to moisture infiltration and accelerating wear. To diagnose hail damage yourself, look for visible dents or bruises, granule loss, or cracks in the asphalt surface after a storm. Walk carefully on the roof if it’s safe to do so, wearing soft soled shoes, or inspect from a ladder with binoculars. Remember to check gutters and downspouts for granules washed off by rain, as this can be a clear sign of damage. Small dents are sometimes only cosmetic, but cracks or punctures must be dealt with promptly to avoid leaks.
If you notice anything suspicious, it’s best to call a professional roofer to conduct a thorough inspection. Ask them how they assess hail damage on BUR systems and whether repairs will affect your roof warranty. Reputable contractors should offer clear advice on whether patch repairs suffice or if sections need replacement. Questions like “Will the repair restore the waterproofing to original standards?” and “Does this repair come with a workmanship warranty?” can help you ensure quality work. Keep documentation of damage for insurance claims, and avoid waiting too long; untreated hail damage can shorten your roof’s lifespan. A roofer can safely and accurately diagnose hidden damage and recommend the most cost-effective fix, from simple patching to full overlay or replacement.
