Guardian Roofing, Gutters & Insulation Overview and Reviews

Guardian Roofing, Gutters & Insulation supplies roofing replacements, gutter systems, and attic insulation to residential customers in the Greater Portland and Willamette Valley region plus Auburn, Washington.

Company Background

The firm has operated for more than twenty years in the Pacific Northwest. Its crews handle projects that address heavy rainfall and seasonal storms common to the area. Services cover both new construction and replacement work on single-family homes.

Roofing Services

Technicians perform full roof replacements and targeted repairs. Every repair includes a seventeen-point digital roof analysis. The company installs Owens Corning shingles and offers a ten percent discount to seniors, military members, veterans, and first responders on qualifying projects. Financing options allow customers to defer payments for the first year on roof replacement or attic insulation packages.

Material and Installation Details

Installers follow manufacturer guidelines for shingle attachment and underlayment. Sales representatives often provide video footage of existing roof and attic conditions to help homeowners understand material choices and energy impacts before work begins.

Gutter Installation and Maintenance

Services include seamless gutter systems, gutter guard products, and professional cleaning. Installers adjust slope to promote drainage and add material at roof-to-gutter transitions when needed. Crews have completed single-day gutter replacements that resolved standing-water issues reported by homeowners. Some customers noted questions after installation about exact slope measurements and screw penetration depth into rafters that required additional clarification from the team.

Common Gutter Project Steps

Work typically begins with an on-site assessment of existing drainage. Crews then remove old sections, install new runs with proper pitch, and verify flow during final inspection. Projects often finish in one day when no structural changes are required.

Insulation and Attic Services

Attic insulation and air-sealing packages reduce energy loss. Representatives use video footage of existing attics to explain how added insulation affects heating and cooling loads. These services often combine with roof work when homeowners request integrated projects.

Warranties and Recognition

Customers receive in-house workmanship warranties ranging from one to twenty years along with manufacturer material and labor guarantees. The company earned the 2022 Owens Corning Excellence and Western Region MVP award and appeared on lists of top one hundred roofing contractors in 2021, 2023, and 2024. Additional recognition includes a 2026 Excellence in Customer Service Award from the Business Intelligence Group.

Customer Experiences

Reviewers assign an average rating of 4.9 stars from 337 submissions. Positive comments highlight crews that clean job sites daily, communicate clearly about options, and finish on schedule. Individual accounts describe professional conduct from sales staff through final inspection, with specific praise for crews that worked around existing conditions and left workspaces spotless. A smaller number of reviews mentioned minor post-installation questions about gutter slope and screw penetration that needed follow-up.

Examples from Recent Projects

One homeowner reported that a sales representative provided video footage of roof and attic conditions and explained financing without pressure. Another noted that an installation crew added material at a roof-to-gutter transition to direct water properly. Several accounts praised single-day gutter replacements that eliminated prior drainage problems.

Selecting a Roofing Contractor

Homeowners comparing bids should verify crew experience with local roof slopes and gutter drainage requirements. The company supplies detailed explanations of material choices and financing terms before work begins. Written estimates outline scope, timeline, and warranty coverage for each project. Prospective customers can request references from recent jobs in their neighborhood to confirm consistency.
