Frequently Asked Questions

  • How long does a commercial flat roof typically last?

    Flat roof lifespan depends on the system type and maintenance quality. Built-up roofing and EPDM systems last 20+ years with proper care. 


    Modified bitumen roofs are designed for 25+ years. TPO and metal roofing systems offer similar longevity. Regular professional maintenance from our team extends these lifespans by detecting and addressing issues early before they cause major damage.

  • What flat roofing systems does BML Roofing Systems install?

    We install all major commercial flat roofing systems including 2-ply modified bitumen, built-up roofing (3, 4, or 5-ply), EPDM rubber membrane, TPO single-ply, metal roofing (galvanized steel, aluminum, copper, stainless steel), and liquid applied coatings. 


    Our partnerships with roofing manufacturers and 20 years of experience mean we can recommend and install the best system for your building's specific requirements.

  • How often should I schedule roof maintenance?

    Professional maintenance should occur at minimum once annually, though inspections twice a year are recommended for optimal roof performance. 


    Regular maintenance allows our team to clear debris from drains, check membrane condition, reseal vulnerable areas, and identify small problems before they escalate into costly emergency repairs or premature replacement.

  • Can you repair leaks in all types of flat roofs?

    Yes, our fully stocked vehicles carry materials for all flat roof types we service. We can investigate, diagnose, and repair leaks in modified bitumen, EPDM, TPO, built-up roofing, and metal systems all in the same visit. Our know-how is approved by many roofing system manufacturers, ensuring repairs follow proper protocols that maintain your warranty coverage.

    We provide commercial flat roofing services throughout Brantford, Hamilton, Burlington, Cambridge, Brantford, Norfolk, Oxford, Toronto, and all surrounding communities. Our family-run company has established 20 years of great standing within the commercial and industrial sector across this entire region.

  • Do you provide free roof inspections and estimates?

    No, but we offer detailed roof inspections that assess your roof's condition, estimate remaining lifespan, and detect actual and potential problems. 


    After our thorough inspection to determine the best course of action, we provide realistic estimates with unforeseen circumstances already factored in. We proudly honour the initial quote we provide with no hidden costs or last-minute changes.
