Roof replacement and re-roofing

Roof Warranties

Architectural re-roofs

Architectural shingles (laminate shingles) feature a dual-layer construction designed for enhanced strength, weather resistance, and curb appeal.

A high-performing roof is a coordinated system made up of essential components.

Our standard system includes:

  • Ice and water barrier
  • Underlayment
  • Starter shingles
  • Roofing shingles
  • Hip and ridge shingles

Together, these form our Secure Choice system, designed for consistent performance and eligibility for enhanced warranty coverage when installed with qualifying products from manufacturers such as Malarkey Roofing Products and GAF.

Metal Roofs

Metal roofing is lightweight—about a quarter the weight of tile and roughly half the weight of asphalt shingles. Many metal roof systems are built for long service life, often supported by manufacturer warranties up to 50 years.

Metal roofs can also improve energy efficiency by reflecting heat from the sun, which may help reduce seasonal heating and cooling demands depending on the building and ventilation design.

Roofing Materials and Systems

Choosing the right roofing material is only part of the decision—the best results come from installing a complete roofing system that matches your home’s design goals and performance needs. Below are the roofing materials and systems we install, along with key benefits and what each option is best suited for in the Portland metro area.

TPO Roofs

TPO roofing membranes (thermoplastic polyolefin) are commonly used for both residential and commercial low-slope roofing applications.

TPO systems are known for their resistance to UV exposure, ozone, and many common chemicals.

Seams are heat-welded, and systems are typically mechanically fastened or fully adhered based on the building and roof design.

GAF Roofing Systems

TGR General Construction installs GAF roofing systems for homeowners who want dependable performance and a clean, finished look. GAF offers a wide range of shingle styles and color options, and we help you choose a system that fits your home’s design goals and long-term plans.

We install roofing as a complete system—using the correct starter, field shingles, ridge caps, and supporting components—so the roof performs as designed and supports applicable manufacturer warranty options when project qualifications are met.

Workmanship Standards Built Around Manufacturer Specifications

A roof is a system. To deliver dependable performance, we install according to manufacturer requirements and proven field practices—so the details that matter most are handled with consistency from start to finish.

We follow manufacturer requirements for:

  • Layout and alignment
  • Fastening patterns
  • Ventilation considerations
  • Flashing and waterproofing details
  • Finishing components (hip/ridge systems)

This supports:

  • Long-term roof performance
  • Consistent installation quality
  • Warranty alignment when applicable

Every roof replacement is completed with a system-based approach designed for Oregon weather and long-term durability.
