Flat Roofing
Flat and Low-Slope Roofing Contractor in Montgomery & Chester County, PA
Flat and low-slope roofing systems are commonly used on commercial buildings, multi-family properties, and modern residential designs. While they appear level, flat roofs are built with a slight pitch to direct water toward drainage systems and prevent pooling.
For over 50 years, Major Construction has installed and repaired flat roofing systems throughout Montgomery County, Chester County, and surrounding Pennsylvania communities. Our team specializes in durable, weather-resistant flat roofing solutions designed to perform in Southeastern Pennsylvania’s seasonal climate.
What Is A Flat Roof?
A flat roof is defined as a roofing system with a pitch of 2/12 or lower. Unlike steep-slope roofs, flat roofs rely on waterproof membrane systems and proper drainage design to protect against standing water.
Because flat roofs are more exposed to ponding water and UV radiation, proper material selection and professional installation are critical to long-term performance.
Flat Roofing Systems We Install
Major Construction provides installation, repair, and replacement of several flat and low-slope roofing systems:
EPDM ROOFNG
EPDM is a highly durable synthetic rubber membrane known for flexibility and weather resistance. It performs well in extreme temperature fluctuations and offers strong resistance to UV exposure.
TPO ROOFING
TPO is a single-ply membrane designed for energy efficiency. Its reflective surface helps reduce heat absorption, making it a popular choice for commercial properties.
MODIFIED BITUMEN ROOFING
Modified bitumen is an asphalt-based system reinforced with polymers for added strength and flexibility. It creates a durable, watertight barrier ideal for many commercial applications.
Our team evaluates your building structure and usage to recommend the most appropriate system for long-term durability and cost efficiency.
Residential Flat Roofing Applications
Flat roofing is increasingly used in residential settings for:
-
Modern home designs
-
Garages and additions
-
Porches and patios
-
Rooftop decks
When properly designed and installed, flat roofs provide a clean architectural appearance and efficient use of space. Proper drainage slope, membrane selection, and flashing details are critical to long-term waterproof performance, and our team ensures every residential flat roof is built for durability and protection.
Commercial Flat Roofing Solutions
Low-slope roofing systems are widely used on:
-
Office buildings
-
Retail centers
-
Warehouses
-
Industrial facilities
-
Multi-family properties
Flat roofs allow for efficient coverage of large surface areas while accommodating HVAC systems, solar panels, and rooftop equipment. With proper insulation, membrane installation, and drainage planning, commercial flat roofing systems provide energy efficiency, long-term performance, and cost-effective protection.
Flat Roof Repair & Maintenance
Flat roofs require routine inspection and maintenance to ensure proper drainage and membrane performance.
Common flat roof issues include:
-
Ponding water
-
Membrane punctures
-
Seam separation
-
Flashing deterioration
-
Drainage blockages
Addressing minor issues early helps prevent more extensive structural damage and interior water intrusion.
Flat Roof Coatings
For flat roofing systems that remain structurally sound but are beginning to show signs of aging, protective roof coatings may be an option.
Coatings can:
-
Extend the life of an existing roof
-
Improve waterproofing
-
Enhance UV resistance
-
Increase energy efficiency
Our team can assess whether a coating system is appropriate or if full replacement is the better long-term solution.
Lifespan of Flat Roofing Systems
The lifespan of a flat roofing system depends on material type, installation quality, and ongoing maintenance. With proper installation and regular inspections, many flat roofs can last 20–30 years or longer.
Professional installation and drainage design are essential to maximizing performance.
