What this service is

Flat Roofing explained

A flat or low-slope roof section is leaking, ponding, or has reached the end of its membrane life.

Any roof section below roughly a 2:12 pitch needs a membrane rather than shingle. That includes rear additions, porch roofs, dormer tops and full flat roofs on the multi-family and commercial buildings common across Garfield, Passaic, Paterson and Clifton.

Flat roofs rarely fail in the middle of the field. They fail at seams, at drains and scuppers, at wall terminations and around penetrations, and they fail faster wherever water sits after rain instead of draining. Ponding is a drainage problem before it is a membrane problem.

A shingle roofer detailing a low-slope section as if it were pitched is one of the most common causes of a leaking addition we are called out to. The membrane, the termination and the drainage all have to be handled as their own system.

Warning signs

When homeowners call us about this.

If any of these describe your roof, a free drone roof inspection will tell you exactly where you stand.

  • Water pooling on the roof more than 48 hours after rain
  • Open, lifted or split seams in the membrane
  • Blisters or bubbles across the surface
  • Cracking or separation where the membrane meets a parapet wall
  • Rusted or clogged drains and scuppers
  • Interior ceiling stains under a rear addition or porch roof
What Alba Pro Construction does

Our flat roofing process.

01

Inspect the whole low-slope assembly

Seams, terminations, drains, scuppers and penetrations are checked and photographed, along with how the roof actually drains.

02

Repair seams, flashing and drains

Split seams, failed terminations and blocked or undersized drainage are repaired rather than coated over.

03

Install TPO and EPDM systems

Full membrane replacement with properly welded or bonded seams and correct edge and wall terminations.

04

Correct the drainage

Where ponding is causing the failure, we address slope, drains and scuppers so the new membrane is not asked to sit in water.

Materials and systems

What we install and why.

TPO membrane
Heat-welded seams and a reflective surface, well suited to larger flat roofs and commercial buildings.
EPDM rubber membrane
Durable single-ply rubber, a common and cost-effective choice for residential additions and porch roofs.
Modified bitumen
Used where a torch or self-adhered multi-ply build up suits the deck and detailing better than single-ply.
Typical project scope

Flat roof repairs are usually completed in one visit. A full membrane replacement on a residential addition typically takes one to two days, and larger commercial roofs are scheduled by section.

Pricing

Flat roof repairs start at $450, with most falling between $450 and $2,500. Full membrane replacement is priced by square footage, deck condition, insulation and the number of penetrations, with a written estimate provided within 24 hours of inspection.

Common questions

What homeowners ask us.

How long does a flat roof last?+

A correctly installed TPO or EPDM membrane commonly lasts 20 to 25 years in New Jersey. Standing water and neglected seams are what shorten that.

Is ponding water on a flat roof a problem?+

Water that remains more than 48 hours after rain accelerates membrane failure and adds structural load. It usually indicates a drainage or slope problem that should be corrected with the roof work.

Can a flat roof be repaired instead of replaced?+

Often yes. Seam splits, failed terminations and drain problems are all repairable when the membrane itself still has life. The inspection photographs show which applies.

Do you do commercial flat roofs?+

Yes. Alba Pro Construction installs and repairs flat and low-slope roofing on both residential and commercial buildings throughout North Jersey.
