Quick answer
What matters first
Put each proposal beside the same checklist. Confirm contractor identity and registration, measured roof quantity, removal, decking, full material system, flashing, ventilation, permits, cleanup, payment milestones, change orders, and both warranties. Mark anything not written as unresolved.
Interactive scope check
Does each estimate answer the same questions?
9 categories still need written clarification before the totals are truly comparable.
Confirm who is making the promise
The proposal should identify the legal business, contact information, current New Jersey home-improvement registration, insurance documentation, and the party responsible for performing or subcontracting the work.
Registration is a baseline verification step, not a substitute for reviewing references, insurance, the written contract, and the actual project scope.
Translate every proposal into the same roof system
List the included removal, deck work, underlayment, leak protection, starter, field material, ridge material, valleys, flashing, penetrations, edge metal, ventilation, cleanup, and disposal. Record exact product lines rather than relying only on a manufacturer name.
When one proposal is silent, ask for a written clarification. Do not assume an item is included because it is common practice for another contractor.
Read the payment and change-order language
Tie payments to clear milestones. Identify deposits, delivery payments, progress payments, final payment, and any financing conditions. The contract should explain how unforeseen work is priced, documented, authorized, and added.
Ask what happens when weather delays the start, material availability changes, or concealed damage is found after removal. A clear process reduces pressure when the roof is already open.
Separate workmanship from manufacturer coverage
A contractor’s workmanship warranty and a manufacturer’s material or system warranty are different obligations. Record the duration, exclusions, transfer terms, registration responsibility, and who responds if a problem develops.
Keep the signed contract, change orders, invoices, photographs, product information, warranty confirmations, and permit records together after completion.

Questions homeowners ask
Clear answers before the next step
How many roofing estimates should I get?
Enough to understand the reasonable scope and compare qualified contractors. The count matters less than making each proposal answer the same questions in writing.
Is New Jersey contractor registration the same as an endorsement?
No. Registration is an important verification step, but homeowners should still review insurance, references, written terms, scope, payment, and warranties.
What if an estimator promises something that is not in the proposal?
Request a written revision or addendum before signing. Verbal explanations are difficult to compare and may not become part of the contract.
