Why Mercer Roofing Co San Antonio Is Kirby’s Preferred Roof Installation Company
We spend a lot of time in Kirby, and it shows in the details we catch before we quote. Our crews know the east side’s pre-1970s homes often have 3/8-inch decking that needs re-nailing or replacement before new shingles go down. We’ve seen builder-grade roofs on 1990s and 2000s homes near Kirby’s newer subdivisions fail early because nobody installed enough intake ventilation. This is the kind of local knowledge that changes a quote from a guess into a real number.
You’ll also know exactly who is coming to your door. Every Mercer technician is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. We send you their name and photo before the visit. That’s the Threshold Standard, the quality framework every Threshold Group location is contractually held to. Grant Whitlock leads our team, and he holds every job in Kirby to the same written guarantee: 365 days, if it’s not done right, we make it right. Kirby homeowners have responded to that clarity with strong reviews and repeat calls.
Styles & brands we work with






Tile Roof in Kirby
Tile roof installation in Kirby is a serious upgrade, and for the right home it’s worth every dollar. A clay or concrete tile roof on a Kirby ranch typically runs $18,000 – $32,000 depending on square footage, tile weight, and whether we need to reinforce the framing underneath. Tile handles Kirby’s UV exposure better than any composition shingle, and it shrugs off the spring hailstorms that chew through asphalt. The catch is weight: many 1950s – 70s ranch homes in Kirby weren’t framed to carry tile without structural reinforcement, so the quote has to include that engineering work up front.
Clay versus concrete on Kirby ranch homes
Clay tile looks right on an older Kirby ranch, but it’s heavy, fragile during installation, and expensive to repair if a branch falls on it. Concrete tile costs less, weighs about the same, and takes impact better. We’ll walk you through both during the estimate.
What a tile quote must include
Any legitimate tile roof installation quote in Kirby should line-item the underlayment, the battens, the ridge and hip tiles, and the structural reinforcement. If a quote doesn’t mention framing, ask why. Tile on an unreinforced 1960s ranch is a leak waiting for the first big storm.
Roof Ventilation in Kirby
Roof ventilation in Kirby is the difference between a roof that lasts twenty years and one that starts curling in eight. Kirby’s summers bake an attic, and without proper intake and exhaust airflow, that heat warps decking, cooks shingles from underneath, and pushes your cooling bill up. A full ventilation retrofit during roof installation in Kirby typically adds $600 – $1,400 depending on the roof’s footprint and what’s already in place. For homes with zero intake vents, it’s the best money you’ll spend on the job.
Intake ventilation on Kirby’s east side
Homes built before the 1970s in east Kirby often have gable-end vents but no soffit intake, which means air doesn’t actually move through the attic. We fix this by installing continuous soffit vents and, where the design allows, a ridge vent that lets hot air escape along the peak. The combination matters more than either one alone.
Builder-grade roofs that suffocate
1990s and 2000s Kirby construction often used just a few box vents or a single power vent, which doesn’t move enough air for a Texas summer. When we replace those roofs, we quote the ventilation upgrade as part of the job because the new shingles will fail early without it. You shouldn’t have to pay for that mistake twice.
Trusted Brands We Service in Kirby
Our Kirby roof installations run on brands we know hold up to Bexar County weather: GAF, CertainTeed, and Owens Corning are the three we install most here. Each has architectural shingle lines with strong wind ratings and solid warranty backing. We can also source Boral tile for homeowners who want a true tile roof without the weight of clay. Because we keep a local material pipeline, Kirby customers don’t wait weeks for specialty shingle colors or ridge caps. You’ll get the same written price up front, regardless of brand.

AfterCommon Roof Installation Problems We See in Kirby Homes
- Rusty nail pops and lifted shingles on east-side homes built before 1975. Builders used thinner plywood decking and fewer fasteners back then. A re-roof without fixing the decking means the new shingles start popping within a few years.
- Under-ventilated attics in 1990s – 2000s Kirby subdivisions. Heat buildup warps the decking and curls architectural shingles well before their rated life. The fix is an intake-and-exhaust ventilation system, installed at the same time as the roof.
- Missing ice and water shield at valleys and eaves on newer infill construction. Some Kirby homes were roofed fast and cheap, and wind-driven rain finds the gaps during severe thunderstorms. We install shield at every valley, eave, and penetration, always.
- Low-slope ranch roofs re-roofed over the original thin decking. The new shingles look fine for a season, then spring hailstorms expose the weak fastening and shingles start letting go. We inspect the decking before quoting so you don’t inherit that failure.
Pricing for Roof Installation in Kirby, TX
A standard architectural shingle roof installation in Kirby runs $8,500 – $11,500 for a 1,400 – 1,800 square foot ranch. Upgrade to a 50-year shingle or heavier underlayment and you’re looking at $12,000 – $14,200. Tile roofs land between $18,000 and $32,000 with structural work included. What moves the needle most is decking condition. On Kirby’s east side, a 1968 home with 3/8-inch plywood often needs partial or full redecking, which adds $1,500 – $4,000 depending on how many sheets are compromised. We give you a written line-item price before any work starts, so you know the decking cost before we tear anything off. Call (254) 276-4369 to schedule your free estimate.

FAQs About Roof Installation in Kirby
Yes, many do. Kirby’s newer subdivisions often have architectural review committees that approve shingle color, shingle profile, and sometimes the roofing brand before work begins. Your HOA may require a specific shingle color range or a dimensional shingle look, and some restrict visible roof penetrations like solar tubes. We’re familiar with Kirby’s HOA-driven requirements and can help you pull the right approval paperwork before installation. Call (254) 276-4369 and we’ll tell you exactly what your development requires.
Look for continuous soffit vents at the eaves and a ridge vent along the peak, not just a few box vents near the top. If your early-2000s Kirby home has only box vents or a single power vent, your attic isn’t moving enough air for a Texas summer, and your shingles are aging faster than their warranty suggests. We can do a ventilation assessment as part of any roof installation estimate. Call (254) 276-4369 to have us check.
Generally no. A roof replacement done by a licensed contractor won’t void your structural or systems warranties, though you should check your builder’s terms for anything specific. What matters more is that the new installation follows the shingle manufacturer’s nailing and ventilation specs, which preserves the shingle warranty. We handle that on every Kirby job and put it in writing. Call (254) 276-4369 for a free estimate that covers your warranty questions.
A “square” is 100 square feet of roof surface, and most Kirby ranch homes are 14 – 18 squares. Ask each contractor for their total square count, their price per square, and whether the decking is included in that price. Some Kirby quotes look lower because they undercount squares or leave redecking as a “change order” later. Our quotes list exact square count, line-item decking costs, and a fixed price before work starts. Call (254) 276-4369 for a quote you can compare line by line.
Only if the framing is reinforced and the decking is replaced first. Clay tile looks right on an older Kirby ranch and handles UV and hail better than shingles, but it’s heavy. Many 1950s – 70s homes weren’t framed for that load, and skipping the reinforcement leads to sagging and leaks. We can tell you during the estimate whether your home is a good tile candidate or better served by a premium architectural shingle. Call (254) 276-4369 for the honest answer on your roof.
