Yes. We address ponding water through multiple approaches: installing tapered insulation to create positive drainage slopes, adding scupper drains or internal drains, and building crickets to redirect water flow. Ponding water is the #1 cause of premature flat roof failure in Chicago.
The most common causes of flat roof leaks in Illinois include: seam failures from thermal cycling, membrane punctures from foot traffic or debris, deteriorated pipe and curb flashing, ponding water that degrades membrane integrity, and UV degradation on uncoated rubber membranes.
If your Chicago flat roof membrane is structurally sound with less than 25% wet insulation, coating is the smart choice — it costs 50–70% less, extends life 10–20 years, and creates zero construction waste. If the membrane is extensively damaged with widespread wet insulation, replacement is more cost-effective.
Absolutely. Many Chicago homes feature flat roof sections over porches, additions, garages, and modern architectural designs. We repair and coat all residential flat roof types including modified bitumen roll roofing, EPDM rubber, TPO, and built-up roofing (BUR).
Most flat roof coating projects in Chicago are completed in 1–2 days for standard residential roofs. Commercial flat roof coatings may take 2–5 days depending on size and surface preparation requirements. We schedule around weather windows to ensure proper curing in Illinois's conditions.
