Roof replacement A dry roof from deck up
A roof replacement removes the old roofing down to the deck, repairs damaged sheathing, and installs new underlayment, flashing, ventilation and roofing. The shingles get the attention, but the flashing at chimneys, walls, valleys and vents is what usually decides whether a new roof stays leak-free. Call 804-566-7669.

1What roof replacement involves
Most roof replacements start with a full tear-off of the old shingles and underlayment so the crew can inspect the roof deck. Some places allow a second layer of shingles over the first, but most codes limit the number of layers, and an overlay hides rotted sheathing and adds weight. A tear-off also lets the crew replace old flashing instead of reusing it, which is one of the most common sources of leaks on a new roof.
Asphalt shingles are the most common choice. Architectural shingles are thicker and more dimensional than flat three-tab styles. Metal roofing, either standing seam or metal shingles, lasts longer and sheds snow well. Tile, slate and wood shakes are heavier or more specialized and may need structural review. Low-slope sections, such as porch roofs or additions, usually need a membrane roof like modified bitumen or a single-ply system instead of shingles, because shingles need enough pitch to shed water.
Under the roofing, the crew installs underlayment, drip edge at the eaves and rakes, and in colder climates an ice-and-water barrier along the eaves and in valleys to help with ice dams. Ventilation is part of the job too: intake at the soffits and exhaust at the ridge or roof vents help control attic heat and moisture. If your attic has signs of moisture or mold, it may help to read about mold before the roof goes on.
How the work usually goes
- Inspection and measurementThe contractor checks the roof, attic and flashing, measures the roof area and pitch, and notes how many layers need to come off.
- Permit and material orderIn most places a permit is pulled, and shingles, underlayment, flashing and vents are ordered and delivered.
- Tear-off and deck repairOld roofing is stripped to the deck, and any soft or rotted sheathing is replaced before anything new goes down.
- Underlayment, drip edge and ice barrierDrip edge, ice-and-water barrier where needed, and underlayment are installed so the deck is protected even before the roofing goes on.
- Flashing, roofing and ventilationNew step flashing, valley flashing, pipe boots and chimney flashing are installed with the shingles or panels, and ridge or roof vents are added.
- Cleanup and final inspectionThe crew removes debris, sweeps the yard for nails with a magnet, and the work is inspected where your area requires it.

3Common mistakes
- Roofing over a failing roofAn overlay can hide rotted decking and old flashing problems, and most codes limit the number of layers. Ask for a tear-off unless the contractor can explain why an overlay makes sense for your roof.
- Reusing old flashingOld step and chimney flashing is often bent, rusted or sealed with caulk. Ask for new flashing where it can be replaced, so the details match the new roof.
- Ignoring attic ventilationPoor ventilation can trap heat and moisture, shorten shingle life and contribute to ice dams. Ask how intake and exhaust will be balanced.
- Not asking about deckingMany quotes cover only a small amount of sheathing replacement. Ask how extra rotted decking will be priced so there are no surprises mid-job.

5Questions
What happens when I call?
Your call to 804-566-7669 connects to an independent local contractor. Describe the project, ask your questions, and decide whether you want a quote. Calling does not commit you to anything. iLikeToFix earns a referral fee when a call connects; here is how that works.
How do I know if my roof needs replacing or just repair?
Isolated damage, such as a few missing shingles or one failed pipe boot, can usually be repaired. Widespread curling, cracking, granule loss, multiple leaks or soft decking point toward replacement. Age matters too, since asphalt roofs wear out over time. A local contractor can check the roof and attic and explain whether repairs will buy you meaningful time.
Can new shingles go over my old roof?
Sometimes. Many codes allow a limited number of layers, often no more than two, but an overlay hides the deck, keeps old flashing in place and adds weight. Some shingle manufacturers also have specific requirements for installing over an existing roof. A full tear-off costs more up front but lets the crew fix rot and install new flashing.
Will I need to leave my house during a roof replacement?
Most people stay home. It is loud, and nails and debris can fall around the house, so keep kids, pets and cars clear of the work area. It also helps to move fragile items off walls and shelves, since hammering can shake the house, and to cover stored items in the attic, where dust and debris can fall through.
Does a new roof include gutters?
Not always. Gutters are often removed or loosened during a roof replacement, and some roofers offer to replace them as part of the job. Ask whether gutters, drip edge and fascia repair are included in your quote. If your gutters are old or undersized, it may make sense to plan gutters and drainage work right after the roof.
