Fat roofs hit their optimal performance at a low pitch.

Here is Westchester and Fairfield particularly on modern style homes we are seeing roofers improperly apply asphalt shingles in situations that are not suitable.
As a rule of thumb, asphalt shingles should only be employed on roofs with a pitch greater than 3/12 (equivalent to 14 degrees).

If your roof has a slope less than a 14-degree angle, opting for a flat roofing system instead is the most appropriate solution for your roof.

However, it’s crucial to ensure that the areas requiring a flat roof coating are installed correctly, as improper installation can lead to drainage issues that may compromise your roof’s longevity and performance in the long run—that is why our gutter and water management experts are uniquely well-suited to flat roofing work. We understand how to manage water and keep it moving down and away from your home.

Flat roof drainage is managed through a slight slope, drainage points, scuppers, and sometimes gutters. Regular maintenance and professional advice are essential to ensure water flows away from the roof effectively and prevents ponding.

To effectively maintain your flat roof here in Westchester or Fairfield County we suggest conducting biannual inspections, clearing debris and ensure drainage systems are unobstructed. Address any damage or drainage issues promptly, maintain gutters, trim overhanging branches, and monitor and recoat the roof as needed.

Schedule regular professional inspections, keep comprehensive maintenance records, and promptly attend to any issues that arise, as proactive maintenance is always the best for the long-term performance of flat roofs.

TPO, short for thermoplastic polyolefin, combines ethylene-propene and polypropylene. It’s a popular single-ply roofing choice, similar to EPDM, made from eco-friendly rubber and synthetics, creating a durable roof layer.

TPO comes in different thicknesses, affecting its longevity, which is about 20+ years, while EPDM can last 50 or more. However, TPO is relatively new, so its long-term performance is uncertain.

EPDM and TPO differ in several ways:

• TPO seams are heat-fused; EPDM uses seam tape.
• TPO reflects sunlight; EPDM absorbs heat.
• EPDM comes in black or white; TPO offers more color options.
• EPDM is mechanically fastened, TPO is chemically adhered.
• TPO warranties are 10-20 years; EPDM is usually 25-30 years.

A high-quality EPDM roof can endure for up to 50 years, barring severe weather damage. It should be noted that the roofs life span will be influenced by factors such as climate, attic ventilation, insulation, and the expertise of the flat roof installation team.
