Inspect the existing roof
We examine visible roofing, flashing, penetrations, drainage points, and signs of moisture so the scope reflects actual conditions.
We plan roof replacement around the roof's condition, the property's needs, and your project goals. Free consultations help set the right scope before work begins.
A new roof system gives the property a defined plan for worn roofing materials and exposed areas.
Replacement can address linked failures across shingles, underlayment, flashing, and roof penetrations.
A documented scope gives homeowners and commercial clients a clearer basis for material and project decisions.

Roof replacement starts with the existing roof, not a preset material list. We review the roof surface, flashing, penetrations, drainage details, and areas where water may have reached the deck. The project may include removal planning, new underlayment, shingles or another selected roofing material, flashing work, and cleanup. The exact scope follows the inspection and the agreed project documents. A roof that needs replacement can hide damage below the visible surface. We take that risk seriously because covering weak decking or failed flashing can lead to repeat leaks. Our position is simple: the plan should address the cause of failure, not only the stain inside the room.

After experiencing water damage in our home, we needed to replace all our flooring, some kitchen cabinets, and redo our primary bath. Linda and her team truly saved the day after a disappointing experience with another contractor. She worked closely with us to choose the perfect tiles for our bathroom and find flooring that suited our home. Her contractors did exceptional work, from leveling the floors to installation and cabinet remaking, all while maintaining a high level of professionalism. Linda answered all our questions along the way, and we cannot speak highly enough of the work she and her team performed!
Best remodel experience we have ever had. The oversight, careful workmanship and ownership of the project was above expectations. Our design team was amazing. We also had the same person do all the work start to finish and was a total Pro. Could not recommend enough and will be doing any and all projects through them. This place is a gem.
Linda and her team did an excellent job! We would highly recommend them. We hired her for a kitchen remodel and asked for a very tight timeline. She delivered and we absolutely love the result. She was very commutative and available to us. Thank you Design and Build NW!

A repaired leak can return when water travels from a wider roof failure or damaged flashing. The visible stain may sit away from the entry point, so the roof surface and nearby penetrations need review. We inspect the affected area, trace the likely path, and explain whether replacement scope is more suitable than another isolated repair.
Curling, missing, or brittle shingles across several slopes can make patching a poor fit. The roof may also contain worn underlayment or weak deck areas beneath the surface. We assess the roof as a system, discuss suitable material choices, and prepare a documented scope that shows which areas the project addresses.
A commercial roof replacement must account for building access, occupants, deliveries, and work areas. Roof issues can also affect interior finishes, equipment, or business operations below. We discuss the property layout and project needs during consultation, then organize the scope so the owner can review materials, access, and handover details before work begins.
