WARNING SIGNS

Signs your flat roof needs attention

Flat and low slope roofs fail differently than pitched roofs. Water doesn’t shed the same way, so small problems become expensive ones fast. Watch for these signs.
8 symptom bullets:

Ponding water that stays 48 hours after rain
Bubbles, blisters, or ridges in the membrane surface
Visible seam separation or lifted flashing
Water stains on interior ceilings or walls below the roofline
Soft or spongy spots when walking the roof
Cracking or alligator patterns in the membrane
Musty smell in upper floors or attic space
Energy bills climbing without explanation

Closing line: If any of these sound familiar, call (845) 448-9411. We can usually diagnose the issue in one visit.

FLAT ROOFING SYSTEMS

Flat and low slope roofing systems we install

Every flat roof has different demands based on building size, foot traffic, climate exposure, and budget. GKontos installs four proven systems so you get the right match for your property.

EPDM Rubber Roofing EPDM (ethylene propylene diene monomer) is a single-ply rubber membrane known for long-term durability and weather resistance. As a certified Elevate EPDM installer, GKontos provides fully adhered or mechanically fastened systems with a 20-year manufacturer warranty. EPDM resists UV radiation, ozone, and temperature swings common in the Hudson Valley. Available in black (heat-absorbing for colder climates) and white (reflective for energy savings).

TPO Single-Ply Roofing TPO (thermoplastic polyolefin) is a heat-welded single-ply membrane that provides strong seam integrity and energy efficiency. The white reflective surface reduces cooling costs in warmer months, and the hot-air welded seams create a watertight bond stronger than the membrane itself. TPO works well on commercial buildings, additions, and low-slope residential sections where reflectivity matters.

Modified Bitumen Roofing Modified bitumen is an asphalt-based system reinforced with polyester or fiberglass for added strength and flexibility. GKontos installs torch-applied, cold-adhesive, and self-adhered modified bitumen systems from Mule-Hide. This material handles foot traffic better than most single-ply options, making it a strong choice for roofs with rooftop HVAC units, solar panels, or regular maintenance access.

Rolled Roofing Rolled roofing uses mineral-surfaced asphalt rolls for low-slope applications where the pitch is too shallow for standard shingles. As a certified Mule-Hide installer, GKontos offers 15-year and 20-year warranty options with a variety of color choices. Rolled roofing is a cost-effective solution for porches, garages, sheds, and additions.

Flat Roof Repair Membrane punctures, seam failures, flashing separation, and ponding water are the most common flat roof problems in the Hudson Valley. GKontos diagnoses and repairs all flat roofing systems, regardless of the original installer. We carry EPDM, TPO, and modified bitumen patch materials on every service truck.

Flat Roof Maintenance Seasonal inspections catch small problems before they require full replacement. GKontos offers maintenance programs that include membrane inspection, seam testing, drain clearing, flashing checks, and written condition reports.

Our Work

It was a pleasure to do business with a contractor who came on time, had a great team of workers and took care to protect my flowers and plantings while the roof was being replaced. House now looks stunning as the colors coordinate with the brick facing, the orange front door and even the lilies that were blooming at the time!

FAQ

Common questions about flat and low slope roofing

How much does a flat roof cost in the Hudson Valley?

Flat roof pricing depends on square footage, the membrane system you choose, the condition of the existing deck, and whether tear-off is needed. EPDM and rolled roofing tend to be the most affordable options. Modified bitumen and TPO fall in the mid-range. Every project starts with a free written estimate so you know the full cost before any work begins.

How long does a flat roof installation take?

Most residential flat roofs take one to three days depending on size and weather. Larger commercial projects may run longer. GKontos schedules your install date in advance and provides daily progress updates if the project extends beyond one day.

What warranty comes with a flat roof from GKontos?

Elevate EPDM installations carry a 20-year manufacturer warranty. Mule-Hide modified bitumen and rolled roofing systems offer either a 15-year or 20-year warranty depending on the product selected. Every warranty is provided in writing at project completion.

Which flat roofing material is best for my building?

EPDM works well for most residential flat roofs and handles Hudson Valley temperature swings. TPO is ideal when energy efficiency and reflectivity matter. Modified bitumen handles foot traffic and rooftop equipment better than single-ply options. Rolled roofing is a cost-effective option for smaller structures. GKontos walks you through samples and recommendations during the free

Do you handle permits and inspections for flat roof work?

GKontos pulls all required permits and meets the building inspector on site. Permit costs are included in the quoted price. License numbers WC-27658-H15 and PC-7715 are on file with the state.

Can you repair my flat roof even if another company installed it?

Yes. GKontos repairs all flat roofing systems regardless of the original installer or material type. We carry EPDM, TPO, and modified bitumen patch materials on every service truck for same-day repairs when possible.

How do I know if my flat roof needs replacement or just a repair?

If the membrane has localized damage (a puncture, a failed seam, flashing separation), a targeted repair is usually sufficient. If you see widespread blistering, chronic ponding, multiple patch areas, or the roof is past its expected lifespan, replacement is the better investment. GKontos provides an honest assessment during the free evaluation with no pressure to replace if a repair will hold.

What is the lifespan of a flat roof?

EPDM membranes typically last 25 to 30 years with proper maintenance. TPO systems average 20 to 25 years. Modified bitumen runs 15 to 20 years depending on the number of layers. Rolled roofing averages 10 to 15 years. Regular inspections and maintenance extend the life of any flat roofing system.

Do you offer financing for flat roof projects?

Yes. GKontos offers 0% financing through GreenSky for qualified buyers. The application takes about 60 seconds and you get a decision the same day.

Are your flat roof installers certified?

GKontos holds active installer certifications from Elevate (EPDM systems) and Mule-Hide Products (modified bitumen and rolled roofing). These certifications require ongoing training and allow us to offer full manufacturer warranties. GAF Master Elite certification (ME45976) covers our shingle and steep-slope work.
