Signs Your Flat Roof Needs Attention

Watch for standing water that remains more than a couple of days after rain, cracking or blistering on the surface, separated seams or flashing, and stains on the ceiling below. Flat roofs fail slowly and then quickly, so catching problems early saves money.

Roofing Materials We Install

Roofing material Typical lifespan Best for
Asphalt shingles (architectural) 20–30 years Most New Jersey homes; best value, many colors and styles
Metal roofing 40–70 years Long-term owners, snow shedding, energy efficiency
Flat roofing (EPDM rubber and low-slope membranes) 15–30 years depending on the system Porches, additions, garages, rowhouses and flat-roof sections

Lifespans are typical ranges and depend on installation quality, attic ventilation and maintenance.

Frequently Asked Questions

How long does an EPDM rubber roof last?

A properly installed EPDM roof commonly lasts 20 to 30 years with basic maintenance.

Can a flat roof be repaired instead of replaced?

Yes, if the membrane is mostly sound. Seams, punctures and flashing can be repaired. If the membrane is brittle or the insulation underneath is wet, replacement is usually needed.

Why does water pond on my flat roof?

Ponding is usually caused by sagging decking, poor drainage or clogged drains. We correct the slope and drainage during repair or replacement.

Do you install flat roofs on porches and additions?

Yes. Porches, additions, garages and dormers with low slopes are some of our most common flat roofing projects.
