Professional Flat Roofing - GHS Construction

Flat Roofing: Robust and Ready for Anything

When it comes to flat or low-slope roofs, you need a system built for maximum resilience and watertight integrity. Flat roofing offers an incredibly strong and practical solution, ideal for modern architectural designs and commercial properties. GHS Construction specializes in high-quality flat roof installations, delivering superior resistance to the elements, straightforward maintenance, and efficient use of space. Our flat roofing options are engineered for longevity, providing a reliable and secure covering for your property, no matter the challenges.

Why You Should Choose Professional Flat Roofing

Flat roofing provides an incredibly durable and practical solution for specific architectural designs and commercial properties, but its long-term performance hinges on expert installation. At GHS Construction, we deliver high-quality flat roof replacements built for superior waterproofing and lasting resilience. Here are five key reasons why investing in a professionally installed flat roof is a smart choice for your property.

Watertight Seal

Flat roofs rely heavily on meticulous sealing to prevent water ingress. Professional installers ensure every membrane seam, corner, and edge is perfectly sealed and waterproofed, providing unparalleled protection against leaks and moisture damage.

Space Utilization

The design of flat roofs can open up opportunities for rooftop patios, green spaces, or HVAC unit placement, maximizing your property’s functional area. Expert installation accounts for proper weight distribution and access.

Durability

Modern flat roofing materials are incredibly tough and designed to withstand heavy loads, punctures, and harsh weather. A professional installation guarantees the materials are applied correctly, maximizing their inherent strength and lifespan.

Drainage Solutions

Proper slope and drainage are critical for flat roofs to prevent water pooling. Professional contractors design and implement effective drainage systems to ensure that the water quickly sheds off the roof, prolonging its life.

Maintenance Access

While flat roofs are durable, their design often allows for easier and safer access for inspections and maintenance compared to steeply pitched roofs. Professional installation ensures all components are easily accessible for any necessary upkeep.

Answers for Your Flat Roofing Questions

The lifespan of a flat roof varies significantly depending on the material used (e.g., EPDM, TPO, PVC, Modified Bitumen) and the quality of installation. With professional installation and proper maintenance, many modern flat roofing systems can last 20-30 years or even longer.

Flat roofing offers excellent waterproofing, is durable for a variety of weather conditions, allows for efficient use of rooftop space (e.g., for HVAC units or even green roofs), and provides a clean, modern aesthetic.

Look for standing water (ponding), visible cracks or blisters in the membrane, tears or punctures, “alligatoring” (cracking that resembles alligator skin), separated seams, or water stains on the interior ceiling.

We use advanced techniques and high-quality membrane materials specifically designed for flat roofs. Our expert installers pay meticulous attention to detail, ensuring all seams are properly welded or adhered, and all flashing around penetrations (vents, skylights) is perfectly sealed to prevent leaks.

While seemingly flat, properly installed flat roofs actually have a slight slope to direct water towards drains. Issues with water pooling often indicate a problem with the roof’s slope, blocked drains, or structural issues. GHS Construction ensures correct sloping for optimal drainage.

The installation time for a flat roof depends on the size and complexity of the area. Generally, flat roof installations can be quicker than pitched roofs due to the continuous membrane application. We’ll provide a clear timeline during your consultation.
