Roof replacement in Killeen and Central Texas.

The system, not the shingle

A roof is five or six things working together.

Most people shop a roof replacement by comparing shingle brands. The shingle matters, but it is the visible layer of a system, and in Central Texas the parts underneath it are usually what decide whether the roof lasts its full rated life. Here is what actually goes on a roof and why each piece is worth asking about when you compare bids.

Tear-off and decking

Everything comes off down to the wood. That is the only point in the roof life cycle where the decking can be inspected, and on older homes around Killeen and Copperas Cove it is common to find a few soft or delaminated sheets, especially around chimneys, valleys, and anywhere a leak ran for a season. Bad decking gets replaced. Nobody can tell you how many sheets that will be before the old roof is off, so the scope should state a per-sheet price up front instead of leaving it open.

Underlayment and the leak barriers

Synthetic underlayment has largely replaced felt because it holds up better to foot traffic and to sitting exposed for a day or two in Texas sun. The more important detail is where a self-adhering leak barrier goes: valleys, around penetrations, and along roof-to-wall transitions. Those are the places that leak first, and a membrane there is cheap insurance compared to chasing a valley leak in three years.

Flashing, drip edge, and transitions

Reusing old flashing is the single most common corner cut on a replacement bid. Step flashing at walls, chimney flashing, and drip edge at eaves and rakes should be new metal, and a chimney that is properly flashed has counterflashing let into the masonry rather than a bead of caulk smeared across the brick. If a bid is noticeably cheaper than the others, this is usually where the money went.

Ventilation

Attic ventilation is balanced intake at the soffit and exhaust at or near the ridge. Get it wrong and the attic runs hot enough through a Central Texas summer to cook the shingles from below, which shows up years later as premature curling. A replacement is the right time to fix an attic that has never breathed correctly, and it is a small line item compared to redoing it later.

Choosing the material

Architectural or dimensional laminated shingles are the default on most homes here. They are heavier than the old three-tab, hold their seal better in wind, and carry longer manufacturer ratings. Three-tab still shows up on rentals and budget jobs, and it is the first thing to blow off in a hard spring wind.

Impact-resistant Class 4 shingles are worth pricing in this part of Texas. They cost more, they hold up better to hail, and many insurance carriers give a premium discount for them. Call your carrier and ask what the discount actually is on your policy before you decide, because it varies enough to change the math.

Metal is the other real option, particularly on porches, low-slope sections, steep architectural roofs, and buildings where you want to stop thinking about the roof for several decades. It costs more up front and lasts far longer. If you want to compare the two side by side, the metal roofing page walks through panel types and gauges.

What a replacement actually costs

Square footage is where the estimate starts and not where it ends. The things that move the price are pitch, because a steep roof slows everything down and changes how the crew works; complexity, because valleys, dormers, and cut-up roof lines mean more cuts, more flashing, and more waste; the number of layers to tear off; how much decking has to be replaced; access, because a house you can back a trailer up to is cheaper to work than one you cannot; and the material you pick.

• Get the scope in writing, with the underlayment, flashing, and ventilation spelled out rather than implied.
• Compare bids on what is included, not on the bottom line alone. Two numbers that look close often describe different roofs.
• Ask who is doing the work and whether the contractor carries liability insurance. A Classic Roofing does.

How the job runs

Material is delivered, the crew tears off and dries in the same day where the weather allows, decking is addressed, and the new system goes on. Debris is contained while the roof comes off, the site is cleaned at the end of every working day, and the ground gets swept with a magnet for nails before the crew leaves. Bill Webster has been doing this in Central Texas for more than thirty years, and the company is family owned, which mostly means the person who sold you the job is the person you call if something is not right.
