Flat Roofing

Flat & Low-Slope Roofing in LA County

Flat roofs are common on mid-century homes, additions, garages, and virtually all commercial buildings in LA County. Palm Crest Roofing installs modified bitumen (mod-bit), built-up roofing (BUR), and single-ply systems (TPO, PVC) for low-slope applications. We also handle hybrid roofs with tile or shingle sections.

Key Benefits

• Modified bitumen (torch-down and cold-applied)
• Built-up roofing (BUR) with gravel or cap sheet
• Single-ply membranes (TPO, PVC) for commercial and large residential
• Proper slope and drainage design to prevent ponding
• Primer, base sheet, cap sheet, and proper flashing at all penetrations
• 15–30 year lifespans depending on system

Our Process

Step 1: Inspection & Scope

Assess existing roof, drains, penetrations, and slope. Recommend the right system for your building.

Step 2: Tear-Off

Full tear-off to the deck when needed, or clean prep for a recover when appropriate.

Step 3: Deck Repair & Insulation

Replace rotted deck, install or upgrade insulation and cover board for energy efficiency.

Step 4: Base & Cap

Base sheet and cap sheet (or membrane) installed with mechanical fasteners, adhesive, or torch per system.

Step 5: Flashings & Drains

New flashings at parapets, walls, drains, and penetrations. Ensure all drainage paths are clear.
