5 Signs You Need a Full Roof Replacement: The Gresham Roofing and Construction 2026 Checklist

Most advice on roof longevity misses a simple truth: a roof's calendar age does not tell you nearly as much as how it has held up to the weather. A 15-year-old roof in the Pacific Northwest has weathered a completely different story than one in a dry climate. This kind of local, specialized knowledge is what drives demand across the roofing industry, one of the most consistently active sectors in residential construction.

Here in the Gresham and Portland metro area, Gresham Roofing and Construction has built its reputation on a deep understanding of these regional challenges. With a history stretching back to 1968, their expertise is well-established.

Knowing the specific signs of a failing roof is not just about stopping a leak. It is about protecting the structure and value of your home. Putting off a replacement can turn a straightforward job into a massive repair, one that could involve structural work, mold remediation, and new insulation. This checklist covers five clear signs that your roof needs to be replaced.

Experience and Legacy: Many contractors have been around for 5 or 10 years. Gresham Roofing and Construction is a third-generation family business that was established in 1968, bringing more than 50 years of continuous service and local expertise to every job.
Warranties: A typical warranty might cover materials for a limited, pro-rated period and labor for only 5 to 10 years. As a factory-certified installer for GAF, Owens Corning, and Versico, Gresham Roofing and Construction provides non-prorated, transferable lifetime labor and material warranties, which is a much higher level of quality assurance.
Scope of Service: Some roofers only install shingles. Gresham Roofing and Construction is a full-service exterior construction company, equipped to handle dry rot repair, siding, windows, and decks. This means you have a single, accountable partner for even the most complex projects.
Certifications: Most roofers are licensed, but very few earn top-tier certifications from manufacturers. Being a GAF-certified roofer is a mark of quality that requires continuous training and a proven history of excellent installations.
