Quick answer: Xactimate and Symbility are accurate estimating tools when used correctly, but roof estimates often come up short because of how they’re set up and applied. The most commonly missed items are pipe boots and vent components, drip edge, valley metal, a realistic waste factor, steep-pitch tear-off labor, decking over spaced boards, and property protection. Each can be raised with photos, measurements, code references and manufacturer requirements.
If you’ve filed a property claim, your insurer probably used Xactimate or Symbility to calculate what it owes. These programs are industry standard, and on paper they’re fair. The problem is how they’re often used: by undertrained reviewers following internal guidelines that override real construction practice.
No. They were built for detailed, line-item estimating, and in experienced hands they produce accurate pricing. A hammer works great, unless someone uses it as a screwdriver. The issue is selective line items, adjusted settings and “that’s our guideline” answers nobody will explain.
The common excuse is “no visible storm damage.” But many of these components have to come off to install a new roof, and reusing old, worn parts on a brand-new roof is a shortcut that invites leaks.
Every valley, wall, chimney and cut line creates unusable shingle waste. Long-standing industry practice has been roughly 10% on simple gable roofs and around 15% on hip roofs. When waste is cut to 3% to 5%, the estimate assumes almost no offcuts, which isn’t realistic.
Steep roofs are slower and more dangerous to remove and install, requiring harnesses and extra care. Paying a steep charge for installation but not for removal doesn’t make sense. The roof didn’t get flatter during tear-off.
Many older and rural homes have spaced plank decking. Shingle manufacturers and code generally require solid decking under asphalt shingles. If your policy includes ordinance or law coverage, this can be a significant item.
Drip edge is thin metal that often bends during tear-off and is code-required in many areas. “No visible storm damage” isn’t a reason to reinstall mangled metal.
Tarps, plywood barriers and extra labor to protect landscaping, stonework and delicate areas are part of doing the job right, but often aren’t on the first estimate.
Ask for the reason each item was omitted, in writing. Then have your contractor submit a documented roofing supplement with photos, measurements, code citations and manufacturer requirements.
When someone points to the software as proof an estimate is right, ask what was left out and why. A tool is only as good as the person using it.
Xactimate is estimating software widely used by insurance adjusters and contractors to price property repairs line by line.
It depends on roof complexity. Simple gable roofs often run around 10% and hip or cut-up roofs around 15%, based on measured roof geometry.
Insurers sometimes omit it if they don’t see storm damage. If it’s required by local code or damaged during tear-off, ask your roofer to document it.
Your contractor typically submits documentation of missed repair items. Bold Roofing provides documentation and estimates but does not negotiate claims.
