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

A complete 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 source of the problem should be evaluated before the repair is selected.

We install roofing for new construction, additions and larger exterior projects. The roof assembly must be planned around the structure, deck, 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 reviewed before the new roof system is installed.
Shingles that are cracked, lifted or missing can leave parts of the roof more vulnerable to water entry.
A leak that returns after repairs, or appears in more than one area, may point to a broader roofing or flashing problem.
Water stains on ceilings or dampness in the attic can be signs of a roof problem. The visible stain may not be directly below the point where water entered.
Soft decking or a visibly uneven roof surface may indicate deterioration that needs closer evaluation before new roofing is installed.

Available in a range of profiles and colors for residential sloped roofs. The right product depends on the roof design and installation requirements.

The deck supports the roofing system. During replacement, exposed areas can be checked for visible damage before they are covered.

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

Flashing manages water where the roof meets walls, edges and penetrations. These transitions need careful detailing.

Ventilation can affect heat and moisture conditions beneath the roof. Existing attic conditions should be considered when planning the work.

Valleys and roof edges direct water toward the drainage system. Debris buildup and damaged details in these areas deserve attention.

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

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

With the old roofing removed, we examine the exposed decking and roof edges for visible damage or deterioration.

If damage is found, we explain the needed repair and any change to the scope. Once approved, compromised decking or related components are repaired or replaced before new roofing covers them.

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

We install the new shingles and applicable finishing components, review the completed work and clean up the roofing debris included in the project scope.
Happy Valley includes both relatively level neighborhoods and hillside areas around Mt. Scott and Scouters Mountain. A roofing estimate should account for the property as well as the roof. On a sloped or restricted lot, material delivery, equipment placement, tear-off debris and protection of landscaping may require more planning.
Roof conditions can vary across the same home. Tree-shaded areas may stay damp longer and collect leaves or needles near valleys and gutters, while more exposed roof planes may take more wind and rain. During an evaluation, we consider accessible roofing, flashing, penetrations, valleys, drainage and visible areas of concern before discussing repair or replacement.

From start to finish, from getting an estimate to completing the project, these guys did a GREAT job: installing siding, putting up exterior moldings, and replacing exterior windows and doors with great quality.

Permit requirements depend on the property and the exact scope of work, particularly when structural work is involved. For a property inside Happy Valley city limits, the proposed work should be checked with the City of Happy Valley Building Division before construction.
It can. A sloped or restricted lot may affect equipment placement, material delivery, debris removal and protection of nearby surfaces. These site conditions should be considered when the roofing scope and schedule are planned.
Sometimes. A focused repair may be appropriate when the source is identified, damage is limited and the surrounding roof remains serviceable. Water can travel before it becomes visible indoors, so the entry point should be evaluated first.
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.
Gutters do not always need to be replaced with the roof. Their condition, attachment, drainage and coordination with the roof edge should be evaluated to determine whether they can remain or should be included in the project.
The timeline depends on roof size, pitch, complexity, access, material availability and weather. Concealed decking damage can also change the scope. A more useful schedule can be given after the roof and property are evaluated.
