Key points
- Aging asphalt-shingle roofs
- Multiple leak locations
- Widespread storm damage
- Major ventilation or decking corrections
What should be included in the replacement scope?
Look for tear-off layers, underlayment, ice and water protection where applicable, flashing, ventilation, decking-unit prices, disposal, cleanup, permit responsibility, product details, and both manufacturer and workmanship warranty terms.
How to compare estimates
Compare the actual system and scope, not only the bottom-line price. A lower quote may exclude decking, flashing, ventilation changes, permit handling, or cleanup that another quote includes.
Maryland contract protections
Maryland home-improvement contracts have specific requirements. Verify the contractor's MHIC license and make sure the written contract identifies the contractor, the scope, price, and required terms before work starts.
Questions homeowners ask
How long does a typical roof replacement take?+
Many straightforward single-family roofs can be completed in a few working days, but weather, roof complexity, decking repairs, inspections, and material availability can change the schedule.
Do I need to leave home during roof replacement?+
Usually not, although the work is noisy and creates vibration. Discuss pets, children, driveway access, attic belongings, and daily cleanup with the contractor.
