FAQs
Which flat-roof systems perform best in Rockford’s climate?
For northern Illinois, we typically recommend single-ply membranes such as TPO and EPDM, or a two-layer modified bitumen system. TPO reflects summer heat and resists algae growth, making it ideal for Rockford’s hot, sunny days. EPDM’s rubber composition remains flexible during the region’s freezing winters, preventing cracks. Modified bitumen offers extra puncture resistance for roofs that see foot traffic or hail. We evaluate insulation, deck type, and budget before advising the most suitable system for your building.
How long should a properly installed flat roof last in this area?
Life expectancy varies by material, but with professional installation and routine maintenance, you can expect 20–30 years for TPO, 25–35 years for EPDM, and 25–30 years for modified bitumen in the Rockford market. Factors that shorten lifespan include standing water, foot traffic without walk pads, and lack of semi-annual inspections. Proactive repairs and reflective coatings can often add 5–10 years to any system.
What maintenance does a commercial flat roof require?
Twice-a-year inspections—typically in spring and fall—are recommended. Our technicians clear debris from drains, check seams and flashings, re-seal penetrations, and document membrane wear. After severe storms or heavy snow, a follow-up inspection catches damage early. For customers enrolled in our preventive maintenance program, we provide on-the-spot minor repairs and a digital report with photos, helping you stay ahead of leaks and warranty requirements.
How do you address ponding water problems?
Ponding is common on aging flat roofs and must be corrected to meet the International Building Code and many manufacturer warranties. We first locate low areas with infrared imaging, then propose solutions such as tapered insulation crickets, added roof drains or scuppers, and localized deck leveling. Addressing drainage not only extends membrane life but also reduces ice formation in winter and the extra structural load water adds to the deck.
Are permits or city inspections needed for a flat-roof replacement in Rockford?
Yes. The City of Rockford requires a building permit for any roof replacement exceeding 100 square feet or altering the existing roof system. Our team handles all permit paperwork, schedules city inspections, and ensures your project meets the current Illinois Energy Conservation Code for R-value and air-barrier requirements. We also supply close-out documents—permit, warranty, inspection cards—for your records and future property sales.
What should I expect regarding cost and warranty for a new flat roof?
Pricing depends on square footage, tear-off requirements, insulation thickness, and chosen membrane. In Rockford, budgets generally range from $7–$12 per square foot for a fully adhered TPO or EPDM system and $9–$14 for a modified bitumen roof. We offer manufacturer-backed NDL (No Dollar Limit) warranties of 15, 20, or 25 years, covering both material and labor if the roof ever fails under normal conditions. Optional maintenance agreements are available to keep your warranty in full force for its entire term.
