Flat and low-slope roofing

A low slope. Details that matter.

Flat roofs are usually low-slope roofs. Drainage, seams, and the places where the roof meets a wall or pipe deserve a close look. We can help you understand the problem and the options for repair or replacement.

Types of Flat Roofing We Install

Low-slope covering options include TPO, modified bitumen, and rolled roofing. A proposal should name the covering and explain the deck, insulation, drainage, flashing, and penetrations that go with it. Start with the existing roof so the repair or replacement addresses the whole problem.

Flat Roof Repairs & Inspections

A low-slope roof review can examine drains and drainage paths, seams, flashing, penetrations, membrane condition, and visible signs of moisture. The findings help determine whether repair, maintenance, or replacement is appropriate for the existing assembly.

Flat Roofing & Storm Damage

If weather affects a low-slope roof, Zilker can inspect visible conditions, provide photos and written observations, and estimate roofing work. The property owner and insurer determine policy coverage and claim handling. Repair or replacement options depend on the roof system and the conditions found.

Before you decide

A few good questions.

What is flat roofing and where is it commonly used?

“Flat roof” usually means a low-slope roof with a planned drainage path. These sections appear on some homes, additions, garages, and porches. TPO, modified bitumen, and rolled roofing are different options; the roof and project scope determine which fits.

How do flat roofs drain water if they don’t have a steep pitch?

Low-slope assemblies use designed slope and drainage paths; depending on the roof, those can include drains, scuppers, or tapered insulation. An inspection can look at the existing drainage path and visible ponding, but the roof-specific design and code requirements determine what changes are appropriate.

What are the most common issues with flat roofs in Texas?

A low-slope roof inspection may check for visible ponding, seam separation, membrane damage, flashing defects, blocked drainage, and signs of moisture. Which condition matters and what repairs fit depend on the roof assembly; heat or storm exposure alone does not diagnose a failure.

How often should a flat roof be inspected?

There is no single inspection schedule for every low-slope roof. Follow the selected system’s manufacturer guidance and the maintenance plan for the building; arrange an inspection when there are leaks, visible damage, drainage concerns, or a damaging weather event.

Can a flat roof be repaired or coated instead of replaced?

Repair or coating may be an option when the existing assembly, membrane condition, product compatibility, and manufacturer instructions support it. A coating is not a universal fix; moisture, widespread damage, or other assembly conditions may call for a different scope. An inspection should precede that recommendation.
