EPDM Rubber Sheet for Roof: Frequently Asked Questions

Q1: What is the proper installation method for EPDM rubber sheets on flat roofs?
The sheets should be installed using our specialized roofing adhesive, applied evenly across the substrate. For best results, install when temperatures are between 15-35°C. Overlap adjacent sheets by at least 100mm and use our seam tape to create watertight joints. Always maintain proper drainage slope (minimum 2%) during installation.

Q2: How do you handle roof penetrations and edge details with EPDM sheets?
We provide complementary flashing materials and specialized details for:

Pipe penetrations (using pre-formed collars)

Roof edges (with reinforced termination bars)

Parapet walls (using specialized counter-flashing)

Interior and exterior corners (with pre-formed pieces)
Our technical team can provide detailed installation drawings for complex roof geometries.

Q3: What roof substrates are compatible with your EPDM sheets?
Our sheets are compatible with:

Concrete decks (properly cured and smooth)

Wood substrates (plywood or OSB)

Insulation boards (PIR, EPS, or polyiso)

Existing roofing surfaces (with proper preparation)
We recommend consulting our technical department for specific substrate requirements.

Q4: What is the recommended maintenance schedule after installation?
We recommend:

Bi-annual visual inspections

Annual cleaning of drainage systems

Immediate repair of any punctures or damage

Professional inspection every 5 years
Our maintenance guide provides detailed checklists and repair procedures.

Q5: How does your EPDM perform under heavy snow loads or ponding water?
Our reinforced EPDM sheets withstand:

Snow loads up to 1500 Pa (150 kg/m²)

Continuous water ponding for up to 48 hours

Wind uplift resistance exceeding 6000 Pa
All performance data is verified through independent testing per ASTM D4637 standards.
