Residential roof

The right starting point

Look beyond the shingles.

A stain on the ceiling does not always identify where water enters the roof. Flashing, penetrations, valleys and adjoining walls can all play a role. We review the condition and scope of the problem before discussing a repair or replacement, helping you understand what the proposed work includes.

Explore your roofing project

Roof replacement

Plan removal and replacement with attention to roof geometry, underlayment, edges and finishing details.

Roof repairs

Discuss localized damage or leaks and whether a defined repair is appropriate for the roof's condition.

Flashing & transitions

Review chimneys, walls, valleys and penetrations where different parts of the roof meet.

Ventilation & skylight coordination

Consider roof ventilation and existing skylights as part of the overall project rather than overlooking them until later.

Plan with confidence

Details to discuss before work begins

Review the existing condition

Roof age, visible damage and past leaks help frame the discussion, but the condition of the materials determines the proposed work.

Coordinate connected projects

If a skylight or adjacent siding needs replacement, discussing it with the roof project can help coordinate the flashing and access.

Clarify what the estimate covers

Ask how the scope addresses tear-off, disposal, flashing and any deteriorated decking discovered during the work.

What shapes the estimate?

Roof size, pitch, access, layers to remove, material selections, flashing details and decking condition influence roof replacement cost. A useful estimate explains the intended system and how unexpected conditions will be handled.

Start with your project address, photos, priorities and preferred timing. We review the proposed scope and selections with you before moving forward.

Roofing: helpful answers

Do I need a repair or a full replacement?

That depends on the extent of damage and the condition of the roof. A localized problem may suit a repair, while broader deterioration may call for replacement. We review the specifics before recommending a scope.

Should I replace skylights when replacing the roof?

It is worth reviewing their age and condition together. Coordinating the work can allow the roof and skylight flashing details to be addressed as one project.

Can you quote from a photograph?

Photos are helpful for the initial conversation, especially for visible damage and access. Measurements and an assessment of existing conditions are needed to define the work accurately.
