Roofing Installation & Replacement

A repair may be appropriate when damage is isolated and the surrounding roof remains in good condition. Replacement becomes more likely when damage is widespread, leaks continue to return, roofing materials are significantly deteriorated, or the roof is approaching the end of its expected service life. A roof inspection is the best way to determine the actual scope.

1. Roof Evaluation

We inspect the existing roofing system and look for deterioration, leak sources, flashing issues, ventilation concerns, and other conditions that may affect replacement.

2. Options & Estimate

We’ll explain what we found, discuss appropriate roofing materials, and provide a project estimate so you understand the recommended scope before work begins.

3. Project Preparation

Materials, scheduling, site access, property protection, and other project details are coordinated before installation begins.

4. Roof Installation

The existing roofing materials are removed as required, the underlying roof is evaluated, and the new roofing system is installed with attention to waterproofing, flashing, ventilation, and manufacturer requirements.

5. Final Review & Cleanup

Once installation is complete, the project is reviewed and the job site is cleaned so you’re left with a finished roofing system, not a construction mess.

They are commonly used on residential homes because they can accommodate a wide variety of roof shapes and architectural styles while providing a good balance between initial cost and service life.

The quality of the finished roof, however, depends on much more than the shingles themselves. Underlayment, ventilation, flashing, starter materials, penetrations, valleys, and installation details all contribute to how well the roof performs over time.

Most asphalt shingle roofs last 20 to 30 years, depending on material quality, weather exposure, and installation.

The true lifespan depends on the roofing product, installation quality, ventilation, maintenance, roof design, and weather exposure. Rather than relying only on age, Ferdi recommends evaluating the physical condition of the roofing system when deciding whether replacement is necessary.

There isn’t one standard price for replacing a roof because the scope depends on the home and the roofing system being installed.

Major cost factors include:

• Total roof size
• Roof pitch and complexity
• Asphalt shingles vs. metal roofing
• Number of valleys, dormers, penetrations, and transitions
• Accessibility
• Condition of the roof deck
• Flashing requirements
• Ventilation improvements
• Removal and disposal of existing roofing
• Additional repairs discovered during tear off

Asphalt shingles and metal roofing can both perform well in Western Washington when properly designed and installed. Asphalt provides a lower initial investment and broad design flexibility, while metal generally offers a longer expected service life and lower maintenance. The best choice depends on the home, budget, design, and long term priorities.

Asphalt shingles are layered roofing materials designed to shed water and protect the roof deck beneath them. Modern architectural shingles typically combine a fiberglass base with asphalt and protective mineral granules that provide color and help protect the material from weather exposure.

They are commonly used on residential homes because they can accommodate a wide variety of roof shapes and architectural styles while providing a good balance between initial cost and service life.

The quality of the finished roof, however, depends on much more than the shingles themselves. Underlayment, ventilation, flashing, starter materials, penetrations, valleys, and installation details all contribute to how well the roof performs over time.

Neither material is universally better. Asphalt shingles typically cost less initially, while metal roofing can offer longer service life and strong weather resistance. Homeowners should compare upfront cost, longevity, appearance, maintenance, and plans for the property.

Roofing work can be completed during different seasons, but scheduling and installation must account for weather conditions and keeping the structure protected during the project. Ferdi can advise on timing based on the roof, material, and current conditions.

Project length depends on the size and complexity of the roof, roofing material, weather, site conditions, and whether repairs are discovered after the existing roof is removed. During the estimating process, Ferdi can provide a project specific schedule based on the planned roofing system and scope of work.

Roof replacement costs are typically driven by materials, labor, roof complexity, and any structural repairs that may be needed.

Yes. In some cases coordinating gutter replacement with roofing work can simplify the project, particularly when the existing gutters are already failing or need to be removed during roofing work.

Not necessarily. If both systems are nearing the end of their useful life or share flashing and water-management issues, coordinating the projects may make sense. If one system remains in good condition, replacing it simply because the other needs work may not be necessary.
