Rutherford County has been one of the fastest-growing counties in Tennessee for years running. New subdivisions are going up in every direction from the Murfreesboro city center — off Almaville Road, out past Barfield, along the Christiana corridor, throughout Smyrna, and into the rural stretches of Lascassas and Rockvale. Every one of those new homes gets a roof during construction. Most of those roofs are built to the minimum standard the builder needs to pass inspection and close the sale. That minimum standard and the standard that protects your home for the next 30 years are not always the same thing.
Roof Troops Roofing works with new construction projects across Murfreesboro and all of Rutherford County — veteran-owned, GAF-certified, and committed to installing roofing systems that are built correctly from the first nail, not just passed through inspection. We work directly with homebuilders as a roofing subcontractor, and we work directly with homeowners who are building custom homes and want a contractor who represents their interests, not the builder’s cost per unit.

When you replace a roof on an existing home, the decking is already there. The framing is done. You tear off the old system, inspect what is underneath, and install new. The variables are known.
New construction roofing starts from framing. The roof deck is sheathed before the roofing contractor arrives. The sequence — decking, underlayment, ice and water shield at the eaves and valleys, drip edge, flashing, ventilation, and finally the shingles themselves — has to be executed in the correct order, with each layer properly integrated with the one beneath it. On a new build, there are no second chances to correct a flashing installation that was done wrong because the shingles are already on top of it. A kicked-out flashing that was installed without the proper angle directs water behind the siding for the next 25 years before anyone traces the leak to its source. An ice and water shield that was cut short of the interior wall line becomes a problem the first time Tennessee gets an ice event that backs up under the shingles.
In Rutherford County, the Murfreesboro Building and Codes Department requires permits for new construction roofing and inspects at key stages — specifically the decking phase before underlayment goes down, and the final installation. Passing inspection means the minimum code standard was met. It does not mean the installation was optimized for the home’s long-term performance or that the shingle system chosen will hold up well against the hail and wind events this county experiences every spring.
Those two things — code compliance and long-term performance — are both necessary. Only the second one requires a contractor who actually cares about what goes on your home.
This is the most important section on this page, and it is the section no builder wants you to read before you close on your new home.
Builder-grade roofing refers to the minimum-tier materials a production builder uses to deliver a roof that passes inspection at the lowest cost per square. Across the new construction boom in Rutherford County, the standard builder-grade specification is a three-tab asphalt shingle — the flat, single-layer shingle that has been the entry-level residential roofing product for decades.
Three-tab shingles are not defective. They meet code. They will not collapse. But compared to the architectural shingles that the same manufacturer makes, they are materially inferior in every performance category that matters in Middle Tennessee:
The upgrade cost from three-tab to architectural shingles on a new home is modest relative to the total construction cost. On a typical 2,000-2,500 square foot Rutherford County home, the upgrade is often in the $1,500-$3,000 range. The difference in performance, lifespan, and warranty coverage over 25 years is not in the same proportion.
If you are building a home in Murfreesboro, Smyrna, La Vergne, or anywhere else in Rutherford County, ask your builder what shingle they are speccing. If the answer is three-tab, ask about the upgrade cost. If you are working with a custom builder or managing your own subcontractors, call us before the roofing phase begins.
Understanding the system your contractor is installing is the best protection against a roof that meets the minimum standard instead of the right standard. Here is what a complete, properly installed new construction roofing system in Middle Tennessee looks like:
The foundation of the entire roofing system. Typically 15/32-inch or 7/16-inch OSB (oriented strand board) or plywood sheathing fastened to the roof trusses or rafters. The deck must be flat, dry, and free of defects before any roofing layer goes on. Any warped, wet, or improperly fastened panels compromise every layer above them. On new construction, deck inspection happens at the building department level — but a roofing contractor worth hiring walks the deck before proceeding and flags issues before they are covered over.
A self-adhering waterproof membrane applied at the eaves, in the valleys, and around penetrations. In Tennessee, ice and water shield is required at the eave and must extend at least 24 inches past the interior wall line of the building — meaning far enough inward that if an ice event backs water up under the shingles, the membrane catches it before it reaches the structure. It is also applied at every valley and around every penetration: chimney base, pipe boots, skylights, and wall intersections. This is the layer most commonly shortcut on production builds where material cost is being managed to a per-unit number.
Rolled out horizontally across the entire deck surface, lapping each course over the one below by the manufacturer-specified amount, and secured to the deck before any roofing is installed. Synthetic underlayment is the industry standard on new construction — it outperforms traditional felt in resistance to tearing, moisture absorption, and UV degradation during the construction window when the roof may sit exposed before shingles go on. GAF’s full roofing system warranties require the use of GAF-approved underlayment. Installing a competitive brand’s underlayment under GAF shingles may void the enhanced warranty — a detail most homeowners do not learn until they try to file a claim.
Metal flashing installed at both the eaves and the rakes (the angled edges of the roof on the gable ends). Drip edge serves two functions: it directs water off the roof edge into the gutter rather than allowing it to curl back under the shingles and against the fascia board, and it provides a mechanical termination point for the underlayment at the roof’s edge. Drip edge is required by code in Tennessee. The sequence matters — at the eave, drip edge goes on before the underlayment so the underlayment laps over it. At the rake, drip edge goes on after the underlayment so it laps over the underlayment. Installing both in the wrong sequence is one of the most common production roofing shortcuts, and it produces a leak path that does not show up for years.
Every location where the roof surface intersects with a vertical surface, a penetration, or another roof plane at a different angle requires flashing — specifically integrated metal flashing that is woven into the shingle courses, not simply caulked over the top. The types required on a typical new construction home include:
Step flashing at every dormer and wall intersection — individual L-shaped pieces installed one per shingle course, integrated with both the roofing and the siding system. Step flashing must not be nailed into the wall; differential movement between the wall and roof structure will cause buckling if it is fastened to both.
Valley flashing at every roof plane intersection where two slopes meet — this is where the highest water volume runs. Open metal valleys and closed cut valleys both perform correctly when installed properly. The valley is where the most water moves, the most debris accumulates, and where shortcuts most reliably produce leaks.
Pipe boot flashings around every plumbing vent stack — rubber or lead boots that seal around the pipe with a flange that integrates under the shingles above and over the shingles below. Cheap rubber boots craze and crack in Tennessee’s UV exposure within 10-15 years. High-quality boots or lead flashings last the life of the roof.
Kick-out flashing at every location where a sloped roof edge meets a vertical wall — a small but critical piece that diverts water away from the wall rather than directing it behind the siding. Missing kick-out flashing is one of the single most common causes of rot in the wall assembly directly adjacent to a roofline. It is frequently omitted on production builds.
The first course installed along the eave edge before field shingles begin. Starter strips have a full adhesive strip along the upper edge that bonds to the first course of field shingles and prevents wind from lifting the shingle tabs at the most vulnerable part of the roof. Using a proper starter strip product rather than cutting field shingles in half — a common production shortcut — is required to qualify for GAF’s enhanced wind warranties.
Installed in overlapping courses from eave to ridge, staggered so no vertical seams align between courses. Each shingle is fastened with four to six nails per shingle in the nail zone specified by the manufacturer. Nailing too high (above the nail zone), too low (through the sealant strip), or through the shingle with too few nails are the most common installation errors on production roofing. These errors may not produce an immediate leak, but they compromise the shingle’s wind uplift resistance and void wind warranty coverage.
GAF Timberline architectural shingles — the product we install on new construction in Middle Tennessee — carry a Lifetime Limited Warranty on material defects for the original homeowner, and when installed as a qualifying system by a GAF-certified contractor, the warranty can include enhanced workmanship coverage that the basic builder installation does not provide.
Purpose-made cap shingles installed along every ridge and hip of the roof. Ridge cap shingles are thicker, pre-bent, and designed specifically for the high-wind exposure at the ridge line. Using cut-up field shingles as ridge cap — another common production shortcut — does not provide equivalent performance and does not qualify for GAF’s WindProven warranty, which requires qualifying LayerLock shingles with proper accessories including ridge cap.
This is the component most frequently overlooked during new construction roofing discussions, and it is the one that has the most direct impact on how long your shingles actually last.
Tennessee building code requires balanced attic ventilation — intake at the soffits and exhaust at the ridge — at a minimum ratio of 1 square foot of net free ventilation area for every 300 square feet of attic floor space when intake and exhaust are balanced (the 1:300 ratio). Without a vapor barrier, the code minimum increases to 1:150.
The practical significance is this: an attic in Murfreesboro in July without adequate ventilation can reach 150-160 degrees. That temperature does not just make the space uncomfortable — it is literally baking the shingles from below. Heat accelerates the oxidation of the asphalt that gives shingles their flexibility and UV resistance. A shingle that would normally last 25 years in a properly ventilated attic may fail in 15 under chronic heat stress from inadequate ventilation.
Equally important: improper ventilation voids GAF’s Lifetime Limited Warranty on shingles. The warranty specifically requires that ventilation meet applicable code requirements. A builder who skimps on soffit vent area to reduce material cost is not just violating code — they are installing shingles that are no longer covered by the manufacturer’s warranty from day one.
A continuous ridge vent paired with adequate soffit ventilation is the correct system for most Rutherford County new construction applications. We verify ventilation calculations as part of every new construction scope and specify the correct system before installation begins.
There are two ways homeowners in Rutherford County engage us on new construction:
You are the homeowner managing your own custom build. You have selected your builder, you are managing subcontractor selection, and you want a roofing contractor who represents your interests and installs to a higher standard than the production minimum. In this scenario, we work directly with you — you select the material, you understand what is going on your home, and we install it correctly with full documentation.
You are buying from a production builder and want to understand your upgrade options before closing.Production builders typically offer shingle upgrades as a line item during the selection process. We can advise you on what the upgrade is actually worth and what system questions to ask your builder before you sign. If the builder is not offering the system components that unlock the GAF enhanced warranty — qualifying underlayment, starter strip, ridge cap, and ice and water shield — the shingle upgrade alone may not provide the warranty coverage you think you are purchasing.
We are available as a roofing subcontractor to general contractors and custom homebuilders across Murfreesboro, Smyrna, Christiana, La Vergne, Eagleville, Rockvale, Lascassas, and all of Rutherford County. We carry full licensing, bonding, and insurance for new construction work, provide bid documentation, coordinate with construction schedules, and provide warranty registration documentation at project closeout.
New construction roofing costs are calculated on square footage of roof area, not living area. A 2,000 square foot home with a 6:12 pitch and moderate complexity typically has 22-28 squares (2,200-2,800 square feet) of actual roof surface. Material and labor costs for new construction in Murfreesboro in 2026:
Builder-grade three-tab asphalt shingles: $8,000-$12,000 installed on a typical Rutherford County home, depending on size and complexity.
GAF architectural shingles (Timberline HDZ or comparable): $10,500-$16,000 installed, including qualifying accessories for enhanced warranty eligibility.
GAF Timberline metal shingles or standing seam metal: $22,000-$40,000+ depending on system and home size.
The upgrade from three-tab to architectural on a typical new home is $1,500-$3,500 in most cases. On a $300,000 new home, that represents less than 1.5% of the purchase price for a material difference that affects the roof’s performance for the full ownership period of the home.
Can I choose my own roofing contractor on a production build?
In most cases, production builders use their own roofing subcontractors and do not allow homeowner substitution of individual trades. However, you typically can negotiate material upgrades during the selection process. If you are building a custom home or acting as your own general contractor, you have full freedom to select your roofing contractor.
When during the build does the roofing happen?
Roofing typically occurs after framing and sheathing are complete and the deck is installed. In Rutherford County’s current construction pace, the window between deck completion and roofing installation can vary from days to weeks depending on the builder’s subcontractor schedule. The roof needs to be on before interior work begins and before any moisture can reach the framing.
How do I register my GAF warranty on a new construction home?
Warranty registration is the homeowner’s responsibility. On a GAF system installed by a GAF-certified contractor, you register at GAF’s website using the contractor’s information and the installation date. Registration is required within a specific window after installation to activate transferable coverage and full warranty benefits. We provide all documentation needed for registration at project closeout.
My builder says the roof comes with a 10-year warranty. Is that enough?
A builder’s 10-year warranty typically covers their workmanship — meaning installation errors. It does not cover the shingle manufacturer’s warranty on material defects, which runs separately and for a longer period on qualifying products. The two warranties cover different things. Understanding both is important before you assume your roof is fully covered.
What if I discover a roofing issue after I move into my new home?
New construction roofing problems that appear within the first year are typically covered under the builder’s workmanship warranty. Beyond that window, coverage depends on your specific builder warranty terms. A professional inspection is the first step — it establishes what the issue is, whether it is a material defect, an installation error, or a storm event, and which warranty path applies. We offer free inspections on new construction homes and provide written reports with photographs.
