Flat Roof Installation in Katy, TX

GAF, CertainTeed & Owens Corning Certified Flat Roof Installation in Katy Since 2008

Klein Roofing has been installing flat roofing systems across the Katy area since 2008. We’re certified by GAF, CertainTeed, and Owens Corning, which means the manufacturer warranties on those products cover both materials and labor when we do the work. That triple certification isn’t common, and it matters for a flat roof that has to hold up against Gulf Coast heat, high humidity, and heavy seasonal rain. We’re also BBB-accredited and offer bilingual service for Spanish-speaking property owners.

We install five flat roofing systems: TPO, PVC, EPDM, modified bitumen, and built-up roofing (BUR). Whether you own a single-family home with a low-slope section, a commercial warehouse, or a multifamily property, our certified technicians match the system to your building type, budget, and performance goals. Free inspections and written estimates are available with no obligation, and we’re available 24/7 for roofing emergencies.

Flat Roofing Systems We Install in Katy

Each of the five systems we install has a distinct profile for cost, performance, and application. Our certified technicians walk you through the options during your estimate so you’re choosing with full information.

• TPO: Single-ply membrane with a reflective white surface; Cool Roof Rating Council (CRRC) certified and popular for Katy commercial buildings where summer cooling costs are a real concern.
• PVC: Shares TPO’s reflective properties and CRRC credentials; particularly well suited to buildings with rooftop grease or chemical exposure due to its resistance to oils and solvents.
• EPDM: Durable synthetic rubber membrane with a long track record of UV resistance and flexibility across a wide temperature range.
• Modified bitumen: An asphalt-polymer hybrid practical for lower-slope residential flat roofs and smaller commercial buildings; surfacing options include mineral granules and reflective liquid coatings.
• BUR (built-up roofing): Alternating layers of bitumen and reinforcing felts create multi-layer redundancy; a long service history on commercial and industrial properties.

Every installation includes proper slope built in per building code. Flat roofs require a minimum slope for drainage, and we account for that on every project from day one.

Our Flat Roof Installation Process

Before we recommend a system or put a number on an estimate, we inspect the roof. We use non-invasive infrared technology to locate existing moisture intrusion or hidden vulnerabilities in the substrate before any work begins. That step helps us avoid installing over a problem that could surface later.

Here’s how every project runs:

• Step 1 – Free infrared inspection: We scan the roof with infrared diagnostic equipment to identify moisture and assess existing conditions.
• Step 2 – Full property assessment: We review the substrate condition, drainage layout, and all rooftop penetrations, including HVAC units, vents, pipes, and parapet walls that require correct flashing detail. Penetrations are among the most common leak-entry points on flat roofs.
• Step 3 – Written estimate and approval: You receive a detailed written estimate before any work begins. We don’t order materials or schedule a crew until you’ve given written approval. A projected completion date is set at this stage.
• Step 4 – Installation, quality check, and cleanup: We install to manufacturer specifications, perform a thorough quality check, and leave the job site clean before the crew leaves.

For commercial and multifamily properties, we coordinate directly with property managers to minimize disruption. We also discuss reflective and thermal insulation options during the estimate phase for property owners focused on potentially reducing summer cooling costs.
