Roofing · Sumas, Washington
Roofing in Sumas sometimes accompanies an attic-insulation upgrade, but those are different scopes. If a utility program is part of the budget discussion, ask who will record the attic’s existing insulation before removal or added material changes the evidence.
Tell the roofer whether another provider is assessing the attic. Keep access, photographs and the proposed insulation work coordinated with the covering replacement, without assuming that the roof price or its measured area describes the attic project.

Roof replacement
The preparation task is to establish a usable starting record and a clear boundary between trades. Have the insulation provider assess what is present, identify the area being treated and explain how its evidence will be gathered while the roofer defines the covering and any affected connections.
Ask each provider which surface its quantity describes. Roof covering area and insulated attic floor area should remain identifiable instead of being copied into each other’s allowance.
Agree who supplies the assessment and photographs of existing insulation before it is disturbed. Coordinate that visit with the roof schedule and actual attic-access conditions.
Keep the final roofing work and insulation record recognizable in their documents. Ask who addresses any changed access or ventilation detail when both providers are involved.
Before work begins
Ask Building/Land Use which review applies to the actual roof replacement and any associated construction. Include the insulation proposal if it changes work being assessed; a potential utility incentive is a separate decision.
The roofing calculator does not design attic insulation, measure its treated floor area or determine program qualification. Request those assessments from the responsible provider and administrator.
Ask the administrator about the actual insulation scope and current terms. Do not count a roof-covering price as proof of an eligible insulation measure.
Have the insulation provider identify and measure the area its work treats. Keep that quantity separate from roof-covering measurements.
Agree the record with the responsible provider before disturbance or added material makes the original condition harder to establish.
