Cost to Replace a Roof
Replacing a roof means stripping off old shingles and roofing materials, checking the roof deck and replacing rotted or compromised wood, then adding drip edge, underlayment, roofing felt, flashing, shingles, and ridge caps. It is a hard project because workers must operate at height while the deck must support both people and materials.
Common reasons homeowners do this job
- Existing shingles and roofing materials are worn or damaged.
- The roof deck has damaged, rotted, or compromised wood.
- A homeowner is upgrading the roof with new materials.
- The condition of the existing roof calls for a full replacement.
- Old roofing layers need to be removed before a new roof system is installed.
DIY or call a pro?
A professional should replace a roof. The work carries a high risk of falls and requires professional fall-protection equipment, roof anchors, and strict ladder safety. The roof deck must also be verified as able to support workers and materials before work begins.
Frequently asked questions
- Can I replace my own roof, or should I hire someone?
- A professional should handle a roof replacement. Removing roofing, repairing compromised deck wood, and installing the new layers all take place at height, where professional fall protection and roof-deck verification are required.
- What makes a roof replacement price increase?
- The price scales with the size of the roof, labor time, and the materials selected. Haul-away and disposal of old roofing material can add to the work, and a small project may also involve a minimum or trip charge.
- What should be checked before new shingles are installed?
- The existing roof and decking should be assessed first. Any rotted or compromised wood needs replacement before drip edge, self-stick underlayment, roofing felt, flashing, and new shingles are installed.
- Why are flashing and ridge caps part of a full roof replacement?
- Flashing is installed around chimneys, vents, and valleys before the new shingles are laid from the bottom edge upward. After the shingle edges are trimmed, ridge caps finish the roof at the ridge.
