FAQs
What flat-roof systems do you install in Evensville and how do I know which one is best for my building?
We specialize in the three most proven flat-roof membranes for the Tennessee climate—TPO (thermoplastic polyolefin), EPDM (ethylene-propylene-diene monomer), and modified bitumen. TPO offers excellent UV resistance and white, reflective surfaces that lower cooling costs. EPDM is a durable rubber membrane known for superior flexibility and hail resistance. Modified bitumen delivers multi-ply redundancy and easy repairs. During a free site assessment, we inspect deck condition, drainage, foot traffic patterns, and your budget and energy goals to recommend the membrane that balances performance, longevity, and cost for your specific building.
How long can I expect a new flat roof to last in the Evensville area?
Service life depends on the membrane and maintenance level, but you can typically expect 20–25 years from TPO, 25–30 years from EPDM, and 20–25 years from modified bitumen. Properly installed flashings, proactive inspections, and routine debris removal are essential to hit the upper end of those ranges. Our Roofing Done Right workmanship warranty covers installation defects, and each manufacturer backs their membrane for up to 30 years when installed by an authorized contractor like us.
What routine maintenance should I budget for after my flat roof is installed?
Plan for semi-annual inspections—once in the spring after severe weather season and once in the fall before winter. A typical maintenance visit includes clearing drains, removing branches and leaves, checking seams and flashings, and resealing any minor cracks. Budget roughly $0.10–$0.20 per square foot annually for professional maintenance; this small investment can extend roof life by 5–10 years and protect your warranty.
Can a flat roof help reduce my building’s energy bills in Evensville’s hot summers?
Yes. White TPO membranes reflect up to 80% of solar heat, lowering rooftop temperatures by as much as 60 °F compared to dark surfaces. That translates to 10–15% HVAC savings during peak cooling months. We can also install tapered insulation packages to improve R-value and eliminate ponding water, further boosting energy efficiency and indoor comfort.
How much does a new flat-roof system cost in Evensville?
Prices vary with membrane choice, insulation thickness, and roof complexity, but most commercial flat roofs run between $7 and $12 per square foot installed. A straightforward 10,000-sq-ft TPO installation with R-25 insulation typically falls near $85,000–$95,000, while the same size EPDM project may be about 10% higher. We provide detailed, no-obligation proposals with line-item pricing so you can see exactly where every dollar goes.
Is it better to repair or replace my existing flat roof?
If less than 25% of the surface has damage, leaks are localized, and the membrane is under 15 years old, targeted repairs or a restorative coating can add 5–10 years of life at a fraction of replacement cost. However, widespread blisters, wet insulation, or repeated leak calls usually signal that a full replacement is the more cost-effective long-term choice. We use infrared moisture scans to map saturated areas and provide an objective repair-versus-replace report so you can make an informed decision.
