Two roofing estimates for the same house can land thousands of dollars apart, and the gap rarely comes from the shingles. It usually hides in the lines most homeowners skim: how much decking gets replaced, what goes under the shingles, how the attic breathes, and who pays when the crew finds a surprise after tear off. A cheaper bid is often just a shorter one.

This matters more in an established town than in a new subdivision. Many homes in Stephens County were built in the 1940s, 50s and 60s. Plenty sit on pier and beam foundations, and many have already been through two or three roofs, sometimes with metal laid right over old shingles. Aging framing, board sheathing from the wood shingle era, and years of patch jobs all come to light once the old roof comes off. A good estimate plans for that before anyone climbs a ladder.

Before signing anything, get two things in writing: an itemized estimate and a warranty that covers workmanship, not just materials. Complete Crown Construction, a locally owned Roofing Company in Breckenridge, offers both, with free estimates and a 7 year craftsmanship warranty on every job. Since opening in 2019, its team has brought 25 years of combined experience to roof repairs, full replacements, metal roofing, commercial roofs, emergency calls and storm and hail restoration across Abilene and the rest of Central and West Texas. When a storm is behind the work, they also help homeowners through the insurance claim, which removes a lot of guesswork.

With that settled, here is how to read the rest of any bid, one line at a time.

Tear off and disposal

The first thing to confirm is whether the old roof is coming off at all. Building codes generally allow no more than two layers of asphalt shingles, and an overlay hides whatever is wrong with the deck underneath. Overlays also add weight to old framing and can limit some manufacturer warranties.

A complete tear off line should state how many existing layers are being removed, who provides the dumpster, and whether the crew runs a magnetic sweeper over the yard afterward. On larger lots with dogs, kids or livestock around, a stray roofing nail is not a small detail.

Decking, the line that moves the price

Look for a per sheet price for replacing damaged plywood or OSB, plus how many sheets the base price already includes. This single line explains more price gaps than anything else. A low bid that includes zero sheets can grow quickly once rotten boards turn up around chimneys and eaves.

Older houses add another wrinkle. Some still have spaced board sheathing left over from wood shingles, and asphalt shingle manufacturers expect a solid deck. Covering those boards with new plywood is a legitimate cost, and it belongs in the estimate from day one, not in a change order halfway through. Ask for photos of any decking that gets replaced.

What goes under the shingles

A thorough bid names each layer rather than lumping them together. Expect to see:

  • Synthetic underlayment or felt, identified by type
  • Ice and water shield in valleys and around penetrations, which helps even in a dry climate because wind driven rain finds the same weak spots
  • Drip edge along eaves and rakes, which current codes generally call for with asphalt shingles
  • A dedicated starter strip at the edges, where wind tends to peel a roof back first

When a bid says “underlayment included” and nothing more, ask what brand and where.

Ventilation

West Texas summers turn attics into ovens, and a poorly vented attic cooks shingles from below. Healthy ventilation pairs intake low at the soffits with exhaust high near the ridge. Many older homes never had soffit intake at all, and mixing a ridge vent with leftover box vents can short circuit the airflow.

A careful estimate states what kind of exhaust is going in, whether intake is being added, and whether old vents are being removed and patched. Some shingle warranties depend on proper ventilation, so this line protects more than your utility bill.

The small parts that cause most leaks

Leaks rarely start in the middle of a slope. They start at transitions. Watch for these on the bid:

  1. Pipe boots, ideally a lead or silicone style, since basic rubber boots crack in strong sun
  2. Step flashing where the roof meets a wall
  3. Chimney counterflashing, and whether it is new or reused
  4. Replacement of old roof vents rather than reinstalling rusted ones

Reusing flashing can be fine when it is in good shape, but the estimate should say so explicitly.

The material line itself

“Architectural shingle” is not a product name. The bid should list the manufacturer, the product line, the color, and any impact or wind rating. If you are paying for Class 4 impact resistance, it should appear by name, because your insurer will want documentation before applying any premium credit.

Metal deserves the same detail. Exposed fastener panels, common on ranch buildings and shops, cost less but depend on hundreds of screws and washers that age in the sun. Standing seam hides its fasteners and costs more. The gauge matters too, since thicker panels resist hail dents better. If metal is going over existing shingles, ask how the panels will be fastened and whether a layer of purlins is part of the plan.

The paperwork lines

The last few lines tell you how the job will be managed:

  • A written plan for handling hidden damage, with pricing agreed before work starts
  • A payment schedule that does not demand most of the money upfront
  • Clear separation between the manufacturer warranty and the workmanship warranty, including who registers the product
  • Permit and cleanup responsibilities

If insurance is paying, Texas law requires contracts of $1,000 or more to include a notice that the homeowner must pay the deductible. Offering to waive, absorb or rebate it is illegal, so any contractor who promises to “take care of” your deductible is telling you something important about how they plan to cover the difference.

Lay two finished bids side by side with all this in mind, and the question changes. It is no longer which one costs less. It is which one actually describes the roof you’re getting.
