Built-up roofing (BUR) is a common flat roof system made from layers of felt, tar, and gravel, while ridge vents are ventilation strips typically found along the peak of sloped roofs. Leaks in BUR roofs often result from age-related wear, ponding water, cracked tar, or punctures in the gravel layer. Ridge vent leaks usually come from deteriorated or improperly installed vent covers, damaged flashing, or blown-off vent parts during storms. Diagnosing these issues starts with a careful inspection: for BUR roofs, look for soft spots, blisters, or missing gravel that might allow water to seep in. For ridge vents, visually check for cracks, gaps, or displaced vent components, especially after heavy winds or rain. You can safely inspect the roof from the ground using binoculars or from a ladder if comfortable, while always prioritizing safety and avoiding walking on fragile materials.
While some minor clogs or debris removal in ridge vents can be a safe DIY fix, most BUR roof leaks require professional attention due to the complexity and risks involved in repairing layered roofing materials. When calling a roofer, particularly one experienced with BUR systems, ask if they are familiar with the specific materials in your roof and if their repair methods comply with your roof's warranty conditions to avoid voiding it. Also, inquire about their approach to ensuring proper ventilation after the repair, as poor ventilation can lead to recurring issues. Confirming these points helps ensure your repair will be long-lasting and code-compliant, saving you from further costs and headaches later on.
