Flat & Low-Slope Roofing in Southern Illinois
Flat and low-slope commercial roofs require careful attention to drainage, penetrations, seams, flashing and other details that keep water outside the building. Borum Roof Company provides inspections, repairs and replacement solutions for commercial roofing throughout Southern Illinois.
Low-Slope Roofs Demand Attention to Detail
Unlike steep-slope roofs that shed water quickly, low-slope commercial roofing systems depend heavily on proper drainage and carefully installed roof details. Small problems can allow water to reach insulation, decking or occupied areas below.
Drainage
Water needs a clear path away from the roof. Drainage problems can place additional stress on a commercial roofing system.
Roof Penetrations
HVAC equipment, vents, pipes and other penetrations create critical roofing details that require careful attention.
Flashing & Transitions
Roof edges, walls and transitions between building components are important areas for controlling water.
Roof Surface
Visible damage, deterioration and problem areas should be addressed before they lead to larger roofing concerns.
Protect the Roof Before Small Problems Grow
Commercial flat and low-slope roofs benefit from identifying problems before water reaches the interior of the building. Regular observation and professional evaluation can help reveal concerns that are difficult to see from the ground.

When Repairs Stop Being the Best Investment
Repair can be an excellent solution when a commercial roofing problem is localized. As deterioration becomes widespread, however, continuing to repair individual areas may become less practical.
Borum Roof Company can evaluate the existing conditions and discuss whether continued repair or commercial roof replacement is the better path forward.

Flat & Low-Slope Roofing Questions
What’s the difference between a flat roof and a low-slope roof?
Roofs commonly described as flat generally still have some slope to help move water toward drains, gutters or other drainage points. “Low-slope” is often the more accurate description for commercial roofs that do not have the steep pitch found on many homes.
Can a leaking flat roof be repaired?
Often, yes. Repair may be appropriate when the source can be identified and the remaining roofing system is in serviceable condition. More widespread deterioration may require a different approach.
What causes commercial flat roof leaks?
Leaks can result from several conditions, including damaged roofing materials, flashing problems, penetrations, storm damage, drainage issues or deterioration of existing roofing details.
Do you provide commercial roof inspections?
Yes. Borum Roof Company offers commercial roofing assessments to help identify visible problems and determine the appropriate next step.
