Maryland roof replacement: what to expect

A roof replacement affects more than the visible shingles. The work may involve tear-off, deck evaluation, water-management layers, flashing, ventilation, penetrations, cleanup, permits, and documentation. This guide shows Maryland homeowners which decisions belong in the written scope before work begins and what to review at the end.

1. Confirm replacement is the appropriate scope

Before comparing products or colors, understand whether the recommendation applies to one roof section or the entire system. Ask the inspector to explain:

• Where defects or leaks were observed and how widespread they are
• Whether previous repairs are failing in the same area or across different slopes
• Whether the existing material can accept a durable repair
• What is known—and still unknown—about the roof deck below
• Why replacement is recommended instead of repair or monitoring

Use the Maryland roof-inspection guide to evaluate the written findings and our repair-versus-replacement guide to compare the proposed scopes.

2. Make the estimate describe the complete roofing system

A total price is not enough to compare proposals. Each written scope should identify the roof sections included and the work planned at each layer. Look for:

• Removal: whether existing roof coverings will be removed, how many known layers are included, and how debris will be handled.
• Deck evaluation: how the exposed sheathing will be checked and how additional deck work will be documented, authorized, and priced.
• Water-management layers: the specified underlayment and any protection proposed at eaves, valleys, walls, or other vulnerable transitions.
• Flashing: treatment of chimneys, walls, valleys, plumbing vents, skylights, and other penetrations. Ask what will be replaced and what may be reused.
• Ventilation: what existing intake and exhaust ventilation was observed and whether changes are included. Roofing work should not conceal an unresolved attic-moisture problem.
• Finish material: manufacturer, product line, color, fastening approach, accessories, and stated product or workmanship terms.

3. Review Maryland contract requirements before signing

The Maryland Home Improvement Commission says every home improvement contract must be written and legible, signed by each party, and describe the work and materials. The homeowner must receive a signed copy before work starts. The contract must also identify the contractor and MHIC license number and include approximate beginning and substantial-completion dates.

MHIC states that a contractor cannot accept more than one-third of the contract price as a deposit and cannot accept payment before the contract is signed. Beyond the deposit, make sure the payment schedule is tied to understandable project milestones and that change orders are documented in writing.

4. Verify licensing, insurance, references, and permit responsibility

MHIC advises homeowners to verify the contractor’s license, request references, obtain a current liability-insurance certificate, use a written contract, and ask to see any required building permit before work starts. Permit requirements vary locally, so confirm the process with the county or municipality serving the property.

Use the site’s Maryland contractor checklist before authorizing work.

5. Understand insurance boundaries

A contractor can document conditions and prepare a work proposal, but only the insurer can decide whether a loss is covered. The Maryland Insurance Administration says coverage depends on the cause of damage, policy terms, limits, deductible, and loss-settlement method. Wear, deterioration, and maintenance generally are not covered.

If a claim is involved, keep inspection photographs, the insurer’s written decision, estimates, approved supplements, invoices, and proof of completion together. Do not rely on promises that a roof will automatically be covered.

6. Know what happens during the project

The sequence varies by property and contractor, but a replacement commonly moves through material delivery and site protection, removal of existing roofing, inspection of the exposed deck, approved deck repairs, installation of the specified roof system, flashing and penetration work, cleanup, and a final review. Weather, inspection requirements, access, and concealed conditions can change the schedule.

Before work begins, discuss driveway access, vehicles, landscaping, pets, attic belongings, noise, falling debris, satellite equipment, gutters, and how the home will be protected if weather interrupts the work.

7. Complete a final walkthrough and collect records

Before making the final payment, compare the completed work with the signed scope and approved change orders. Ask the contractor to review any replaced decking, flashing work, ventilation changes, and remaining limitations. Check the property for debris and confirm how any concern will be documented and addressed.

• Final invoice and payment record
• Product line, color, and accessory details
• Workmanship terms and manufacturer information
• Permit or inspection records when applicable
• Written change orders and completion photographs when provided
