Roofing for your Home and Business in Portland, Oregon

When it comes to protecting your home from the elements, roofing is one of the most important aspects. It can be a daunting task when trying to decide what type of roofing is best for your home and understanding how much work and cost are involved. Don’t worry; we’re here to help you in Portland, Oregon!

Roofing materials and techniques have been around for centuries, but what exactly are they? Roofing refers to the design, construction, maintenance, and repair of structures that protect a building from the elements. This includes both exterior and interior components such as rafters, trusses, flashing, and waterproof membranes.

We know many of you have faced troubles with previous roofing work from other professionals you’ve hired. The Dial One team has the solution for many issues our customers face including many possible ways and methods to repair and strengthen your roof for many years to come. We have over 35 years of experience in providing home roofing services to our happy clients and can easily fix your all types of roofing problems.

Why do you need Roofing?

Roofs are designed to provide protection against wind, rain, snow, and other weather conditions while also enhancing the aesthetic appeal of a home or business. They come in many styles, including shingle roofs, flat roofs, and metal roofs which are designed to last for decades when properly installed.

In addition to protecting a building from the elements, an effective roofing service can also provide insulation which helps keep energy bills down. Our Roofing contractors are trained to properly inspect a roof for damage and repair it if necessary.

Siding is another important component of the exterior of a home or business. It protects the building from water infiltration and helps maintain a consistent temperature inside the home or business during all seasons.
