Services
Roof Installation
Our roof installation service specializes in complete roof system replacements using premium materials like cedar shakes, composition shingles, and concrete tiles. The process begins with careful removal of old roofing materials, followed by thorough deck inspection and necessary repairs. We install high-quality underlayment and ice/water shield in vulnerable areas before applying your selected roofing material. Our experienced crews complete most installations within 3-5 days, ensuring minimal disruption to homeowners. We handle all aspects of the project, including proper disposal of old materials and complete job-site cleanup using magnetic nail sweepers to ensure yard safety.
Gutter Installation
Our gutter installation service protects homes from water damage through professionally installed seamless gutter systems. We use on-site gutter machines to create custom-fitted gutters without unnecessary seams, employing professional corner cutting techniques for optimal water flow. Our standard installations use 6-inch aluminum gutters with 4-inch downspouts, finished with baked enamel paint for durability. We emphasize proper installation techniques and post-installation maintenance education to prevent clogs and ensure long-term functionality. Our team ensures proper slope and drainage while maintaining aesthetic integration with your home's exterior architecture.
Roof Inspection
Our comprehensive roof inspection service identifies potential issues before they become major problems. Certified technicians examine all roof components including shingles, flashing, valleys, and ventilation systems. We check for signs of wear, water damage, and structural integrity concerns, providing detailed recommendations for maintenance or repairs. Regular inspections help prevent costly emergency situations by catching issues like missing shingles, damaged flashing, or ventilation problems early. Our inspections include evaluation of attic ventilation and insulation to ensure optimal roof system performance and longevity.

From the estimate forward, I found working with the owner, John Mortensen, to be easy and professional. His bid was clearly the best I received. His crew, especially the supervisor, Humberto were skilled, professional, friendly, and helpful. Humberto's entire attitude was "we will make it right". The crew thoroughly cleaned the premises at the end of each day. The roof looks great, and the repair work they had to do (replacing a 35 year old roof) was done quickly and, again, professionally.
I'm not prone to writing glowing reviews, but I was, quite frankly, thoroughly impressed. Roof replacement is a huge undertaking and intimidating for the owner. I'm quite comfortable recommending John for your roof project. I know this reads too good to be true, but, I assure you, it is true. It hasn't rained, yet, so I can't attest to leak prevention, but I'm confident if there is a problem "we will make it right" will be the response.

Mortensen Roofing has repaired my old flat top roof and installed new gutters. He is prompt and very friendly. Will work with any schedule you have and is always able to fix problems. We had a drain problem with the roof and his idea to correct the problem has worked great.especially with some of these heavy rains. John is the best!
