Call for FREE ESTIMATE The estimate should come from the contractor that has been hired, or considered for a given roof installation project. It should contain each of the following components:
Cost for the roof’s removal
No replacement effort could get underway until after the old roofing had been removed. An estimate of the cost for removal should include the expenses linked to the process of hauling off all the debris.
The contractor’s expected timeline
The timeline should give the length of the project, if the contractor were able to proceed as planned, which would mean proceeding without any unanticipated delay. A very thorough timeline could indicate those points where there might be some type of delay, such as a point where work could not proceed without the delivery of new materials. That addition would be especially useful, if the homeowner’s requests had necessitated the purchase of special materials.
A homeowner should not hesitate to offer some feedback, during presentation of the timeline. The homeowner’s family would deserve to know how their comfort and safety would be preserved, during the installation process. By the same token, the residents of the home that is supposed to get the new roof should know what cleanup efforts should take place, once one operation has ended.
A listing of the warranties that are being offered, once the project has been completed
The homeowner should check to see what has been guaranteed. Was it just the labor, just the materials, or both the labor and the materials?
Homeowners should understand that a roofing contractor’s warranty in San Mateo does not cover the materials that were used during the installation project.
Payment details
This should be more than the estimated cost. It should provide details on any payment plan. It should spell out how much of the bill reflects the labor costs, and how much reflects the cost of materials.
Remember that such detailed information could change at any point, as the project proceeded in the direction of completion. New needs or additional requests could make it necessary to alter the payment details.
What factors might detract from an estimate’s ability to appear trustworthy?
Too little information could make it look like some important information had been overlooked, or purposely ignored. An excess of information might make it look like an effort had been made to confuse the reader, or to hide some fact within the estimate’s huge amount of information.
The clarity of the estimate’s printed matter would play a role in verifying, or calling into question the trustworthy nature of the presented estimate. An absence of clarity would suggest that a minimum amount of effort had gone into completion of the document that could be referred to as an estimate.
