FAQs About Commercial Flat Roof Waterproofing Services
We focus on durable, efficient waterproofing solutions tailored to commercial flat roofs. Our recommendations consider the roof material, building structure, and local weather conditions to ensure long-lasting protection.
How much does commercial flat roof waterproofing cost?
Commercial flat roof waterproofing costs vary based on roof size, existing conditions, and waterproofing system chosen. Liquid applied systems are typically more cost-effective for smaller buildings, while membrane systems work well for larger properties. We provide detailed estimates after thorough inspections, and most businesses find that quality waterproofing saves money compared to ongoing leak repairs and potential interior damage.
What is the best waterproofing system for flat roofs?
The best system depends on your building's specific needs and existing conditions. TPO membranes offer excellent durability and energy efficiency, while EPDM provides proven weather resistance. Modified bitumen works well for high-traffic roofs, and liquid applied systems excel for complex shapes with multiple penetrations. We evaluate your building's use, climate exposure, and maintenance capabilities to recommend the most suitable solution.
How long does commercial roof waterproofing last?
Quality commercial waterproofing typically lasts 15 to 25 years with proper installation and maintenance. TPO and EPDM systems often provide 20 to 25 years of service, while modified bitumen lasts 15 to 20 years. Liquid applied systems may need recoating every 10 to 15 years but significantly extend overall roof life. Longevity depends on installation quality, weather conditions, and maintenance adherence.
Can you waterproof over existing flat roof membrane?
Yes, many existing membranes can accommodate new waterproofing without complete removal, depending on current condition and compatibility. We assess the existing membrane's integrity before recommending overlay options. Some liquid systems work well over properly prepared existing membranes, and modified bitumen can often overlay compatible substrates. Severely damaged systems may require removal for optimal results.
What's included in commercial roof waterproofing service?
Our service includes comprehensive roof inspection, surface preparation and cleaning, repair of structural issues, installation of the waterproofing system, and proper sealing around penetrations. We handle permits, ensure code compliance, provide complete cleanup, and conduct final quality inspection. Service also includes maintenance recommendations and warranty documentation to protect your investment.
