A new roof is one of the larger checks a Garland homeowner writes, so the fair first question is simple: what does it actually cost, and why does the number swing so much from one house to the next. The honest answer is that roofers price by the size and shape of your roof, the material you choose, and what has to come off before the new roof goes on. Garland's housing stock leans established, with a median build year around 1980 and a median home value near $222,000, which means a lot of these roofs are on their second or third covering and the tear-off matters. Here is how the price is built, in plain numbers, so nothing on the estimate lands as a surprise.
Roofers price by the square, not the shingle
The unit that runs a roofing estimate is the square, which is simply 100 square feet of roof surface. A typical Garland home lands somewhere around 24 squares once the pitch and overhangs are counted, though a big two-story or a steep, cut-up roof runs higher. When a roofer quotes a per-square price, that number already folds in the shingles, the underlayment, the nails, the flashing, and the labor to install it all.
Two roofs with the same footprint on the ground can still price differently, because the roof surface is not the floor plan. A steeper pitch means more square footage and slower, more careful work up top. The square is the honest way to compare, so ask any estimate to show the square count and the price per square rather than one lump sum.
What moves the number up or down
A handful of things do most of the work in setting your price, and none of them are mysterious once they are named. The biggest levers are how much roof you have, how steep it is, the shingle tier you pick, and how many old layers have to be stripped before anything new goes down.
Tear-off is the lever people forget. A full roof replacement on an older Garland home almost always strips the old roof first, so confirm the layer count before you compare two bids. Here is the full list of what moves the price:
- Size and pitch: more squares and a steeper slope both add material and labor.
- Material tier: a basic architectural shingle, an impact-rated shingle, a designer profile, or metal each sit at a different price.
- Tear-off layers: pulling one old roof is routine, but a second layer underneath means more removal, more disposal, and often decking repairs.
- Decking found underneath: soft or rotted plywood spotted during tear-off gets replaced, and a fair estimate names the per-sheet price before the work starts.
- Access and complexity: valleys, dormers, skylights, and steep faces all slow the crew and show up in the labor.
The honest material ranges for Dallas County
Here are real ranges for the Dallas County area, per square, for the material and the install together. Treat them as planning numbers, not a quote, since the true figure depends on your roof.
One point before the numbers: the impact class is a toughness grade, not a look. A shingle can be architectural in style and Class 4 in impact at the same time, so choosing durability does not force a change in appearance. The shingle guide lays the styles and the impact ratings side by side.
- Architectural asphalt shingles: about $430 to $660 per square. This is the common choice on most Garland homes.
- Impact-rated (Class 4) shingles: about $540 to $820 per square. Built to take a hail hit, and many Texas carriers offer a premium credit for them.
- Designer or premium shingles: about $660 to $1,000 per square, for a heavier, higher-end look.
- Standing-seam metal: about $970 to $1,540 per square, the long-life option at the top of the range.
Why the written estimate is where surprises die
A price you can trust is a price you can read. Before a single shingle is pulled, a good estimate puts the scope, materials, square count, and price in writing first, including how a decking sheet or an extra layer would be handled if the tear-off turns one up. That written scope is what keeps a $12,000 roof from quietly becoming a $15,000 roof halfway through.
The way to get there is a real look at the roof, not a number guessed from the curb. A free inspection measures the roof, counts the layers, and checks the decking and the flashing, then becomes a documented estimate you can compare against another bid line by line. If you want to see how the pieces add up before anyone visits, the roof cost guide walks through them.
Financing, so a needed roof fits the budget
A roof rarely waits for a convenient month, and paying for one all at once is not the only route. Many of the local roofers offer financing, and the rates and terms are set by the lender and shown up front, so you see the real cost of borrowing before you agree to anything. There is no reason to guess at a monthly figure from an ad, because the actual number depends on the amount, the term, and your credit.
The point of financing is not to talk anyone into a bigger roof. It is to keep a roof that genuinely needs doing from being delayed into a worse leak and a larger bill. If financing is on the table for you, the financing overview explains how the options work and what to ask a lender.
