NW Brothers provides roof repair, installation, and replacement services for homeowners in Clackamas, Oregon. We evaluate accessible roofing, flashing, roof penetrations, valleys, and drainage before recommending work and providing a written estimate.

A complete roof replacement is not always necessary. When damage is limited and the surrounding roof remains serviceable, a focused repair may address damaged shingles, flashing, or another vulnerable roof transition. The likely source of the problem should be evaluated before a repair is selected.

We install roofing for new construction, additions, and larger exterior projects. The roof assembly must be planned around the structure, decking, slope, valleys, penetrations, ventilation, and drainage needs of the home.

Replacement may be appropriate when deterioration affects several roof areas, leaks continue to return, or previous repairs have not resolved the problem. Removing the existing roofing also allows exposed decking to be examined before the new roof system is installed.
Shingles that are cracked, lifted, loose, or missing can leave parts of the roof more vulnerable to water entry and continued deterioration.
A leak that returns after repairs or appears in more than one area may indicate a broader roofing, flashing, or drainage problem. The visible water may not be directly below the point where it entered.
Water stains on ceilings, damp insulation, or moisture in the attic can be signs of a roofing problem. The source should be evaluated before the affected interior surface is repaired.
Soft decking or a visibly uneven roof surface may indicate deterioration underneath the finished roofing. The condition should be evaluated before new materials cover the affected area.

Asphalt shingles are available in a range of profiles and colors for residential sloped roofs. The appropriate product depends on the roof design, project requirements, and homeowner preferences.

The roof deck supports the roofing system. During replacement, exposed areas can be examined for visible deterioration before the new roofing materials are installed.

Underlayment is installed between the roof deck and finished roofing. It must be selected and installed as part of the complete roofing system.

Flashing helps manage water where roofing meets walls, edges, valleys, chimneys, and other penetrations. These transitions require careful detailing because small failures can allow water beneath the finished roofing.

Roof and attic ventilation can affect heat and moisture conditions beneath the roofing system. Existing attic conditions should be considered when the project is evaluated and planned.

Valleys and roof edges direct water toward gutters and other drainage components. Debris buildup, damaged flashing, and deteriorated edge details in these areas deserve attention during a roof evaluation.

We review accessible roof areas and discuss the problem or planned work. Some damage beneath the existing roofing may not become visible until removal begins.

We protect the surrounding work area and remove the shingles, underlayment, and other materials included in the approved tear-off. This exposes the roof deck for further examination.

With the existing roofing removed, we examine accessible decking, roof edges, and adjoining components for visible damage or deterioration.

If deterioration is discovered, we explain the recommended repair and any resulting change in scope. Once approved, compromised decking or related components are repaired or replaced before the new roofing covers them.

We install the underlayment, flashing, and other protective components required for the selected roof system, with attention to valleys, edges, adjoining walls, and roof penetrations.

We install the new shingles and applicable finishing components, review the completed work, and remove the roofing debris included in the project scope.
Clackamas properties can vary in roof design, building height, driveway configuration, surrounding landscaping, and exterior access. Narrow side yards, fences, decks, neighboring structures, and established vegetation may affect material delivery, equipment placement, tear-off debris removal, and protection of the surrounding property.
Conditions can also differ across the same roof. Areas shaded by trees or nearby structures may remain damp longer and collect leaves or needles near valleys, roof edges, and gutters. More exposed roof planes may receive greater wind and rain. During an evaluation, we consider accessible roofing, flashing, penetrations, ventilation, valleys, drainage, and visible areas of concern before discussing repair or replacement.
• Total roof area, pitch, and building height
• The number of valleys and roof-to-wall connections
• Chimneys, skylights, vents, and other penetrations
• The roofing material and underlayment selected
• Removal and disposal of existing roofing
• Flashing and ventilation work included in the scope
• Decking deterioration discovered after roofing is removed
• Property access and material-staging space
• Protection required for landscaping, driveways, decks, and adjoining surfaces
• Weather or site conditions that affect scheduling and installation

Permit requirements depend on the property and the exact scope of work, particularly when structural repairs or substantial decking changes are involved. Because the applicable permitting authority may depend on the property’s exact location, confirm the proposed work with Clackamas County or the appropriate local building department before construction begins.
It can. Narrow driveways, restricted side yards, fences, decks, landscaping, and limited staging space may affect material delivery, equipment placement, debris removal, and protection requirements. These conditions should be reviewed when the project scope and schedule are planned.
Damaged or deteriorated decking should be addressed before new roofing covers it. If a concealed issue becomes visible after the existing roof is removed, we will explain the affected area, the recommended repair, and any change to the proposed scope before that additional work proceeds.
Decking that is damaged or deteriorated should be addressed before new roofing covers it. If a concealed issue becomes visible after the old roof is removed, the affected area and any change to the proposed work should be explained before that additional work proceeds.
Roofing work depends on the weather, the materials being installed, and the ability to protect exposed areas. Scheduling may need to change when conditions are unsuitable for the planned work or the manufacturer’s installation requirements.
Gutters do not always need to be replaced with the roof. Their condition, attachment, drainage, and connection with the roof edge should be evaluated to determine whether they can remain or should be included in the project.
The timeline depends on the roof’s size, pitch, complexity, access, material availability, and weather. Concealed decking deterioration can also change the scope. A more useful project-specific schedule can be provided after the roof and property are evaluated.
