Flat and Low-Slope Roofing Systems

Flat and low-slope roofs are engineered for superior drainage and waterproof performance, minimizing leaks and water accumulation that can cause costly damage. They feature high-R-value insulation and seamless membranes, forming a strong barrier against the elements. Consequently, these roofs enhance building durability and ensure year-round energy efficiency, reducing heating and cooling costs while maintaining indoor comfort.

What Common Commercial Roofing Problems We Fix?

Ponding Water

Ponding water occurs when insufficient drainage or irregular insulation results in water gathering on flat or low-slope roofs, accelerating membrane wear and resulting in leaks. We tackle this problem by regrading the surface with tapered insulation, clearing any blockages from the drains, and applying waterproof coatings to guarantee proper runoff and avert future pooling.

Flashing Failure

Poorly installed flashing around vents, HVAC units, or roof edges can cause water intrusion and leaks, risking structural integrity and leading to costly repairs. We remove damaged flashing, clean the areas, and reseal or replace it with durable materials like premium metal or TPO-compatible options. We also reinforce seams for long-lasting waterproof protection, ensuring peace of mind against future leaks.

Damaged Roofing Membrane

Over time, roof membranes may encounter problems such as cracking, blistering, or puncturing due to influences like UV exposure, foot traffic, and temperature changes. Our expert team employs thorough patching, seam resealing, and infrared moisture scanning to identify vulnerabilities and reinforce a watertight barrier, all without needing a full replacement.



Storm or Tree Impact Damage

Intense winds, broken branches, and storm debris can cause punctures, membrane tears, and significant roof damage. Our Gardena Roofers perform emergency assessments, remove debris, reinforce affected areas, and restore your roof to its original condition.
