Commercial Roofing — San Marcos, Texas

Commercial Roofing Contractor San Marcos TX

San Marcos is a commercial roofing town wearing a residential town's clothes. Of the city's 30,349 housing units, only 10,628 are single-family detached — 35% — while 5,330 sit in buildings of fifty units or more. Owner occupancy is 30.8%, the lowest of any city we serve, because Texas State University anchors the market. The person deciding on most San Marcos roofs is a property manager, an owner's rep or an HOA board, and the roof itself is usually low-slope.

Single-ply membrane — TPO, PVC, EPDM

Mechanically attached or fully adhered, over a tear-off or a recover depending on what the cores actually show. Student housing, retail along I-35 and the outlet corridor, and the older downtown blocks are three different roofing problems and we do not price them the same way.

Modified bitumen and built-up

Two-ply asphaltic systems where foot traffic is constant or the deck has a long repair history. On multifamily buildings with rooftop mechanical and regular service access, the redundancy of a multi-ply system is worth more than a spec-sheet comparison suggests.

Multifamily and steep-slope portfolios

A 200-unit complex is a phasing exercise, not a roofing job. We sequence by building, keep residents' access and parking usable, and report progress in writing so an owner two states away knows exactly where the project stands.

Debris containment to San Marcos's own rules

San Marcos writes this into its adopted code rather than leaving it to good manners. Contractors must maintain a method of containment on every site, keep adjacent streets free of dirt and debris, and keep debris out of unprotected storm water conveyance systems. We build that into the mobilization plan.

Edwards Aquifer care on the west side

San Marcos's core sits in the Edwards Aquifer Transition Zone and the west side sits on the Recharge Zone. The city's storm-water clause at Sec. 3305.4 is not a tidiness rule out there — washing tear-off grit into a storm drain over the Recharge Zone is a genuine environmental problem and we treat it as one.

clock

Occupied-building phasing

Student housing turns over in August; retail cannot close; a hospital never closes. We plan the work around the building's calendar rather than ours, and nothing is left open overnight.

Our process

Four steps from first call to finished.

01

Survey and moisture cores

Full roof walk, core cuts, drainage assessment, photographs of every penetration and curb. On a commercial roof the question is not only whether it leaks — it is how much wet insulation you are already paying to condition.

02

Assembly recommendation with the trade-offs named

Recover versus tear-off, membrane type, insulation and tapered design, written with the reason for each choice and what the cheaper option really costs across ten years.

03

Permit path established, not assumed

San Marcos amended its IBC Section 105.2 to add an exemption: roof covering replacement permits are not required unless the weight of the replacement roof is heavier than the existing covering. That is a weight test, not a material test. We establish which side your scope falls on and confirm anything ambiguous with Planning and Development Services rather than guessing.

04

Install, inspect, close out

Daily dry-in, licensed hauler for the debris, and a closeout package with product data, warranty registrations, core findings and completion photographs for the property file.

Roof types we work on

Asphalt, metal, tile, slate, shake — we know it all.

TPO and PVC single-ply
Most low-slope buildings

TPO and PVC single-ply

Heat-welded seams, a reflective surface that matters through a Hill Country summer, and a clear repair path for a building that will be owned for decades. PVC earns its premium where restaurant exhaust or chemical discharge is involved.

60 mil and 80 mil specified by traffic and exposureTapered polyiso to correct ponding rather than live with itSeams probe-tested, not visually approved
Modified bitumen systems
Heavy traffic and older decks

Modified bitumen systems

Granulated cap sheets take abuse that a single-ply will not, and on a roof with forty years of patches the redundancy of two plies is real insurance. Cold-applied or self-adhered where torch work is unsafe over occupied space.

Panel, fastener and retrofit work
Metal buildings and canopies

Panel, fastener and retrofit work

Most metal roofs fail at the fastener, the closure or the eave long before the panel goes. We price the detail repair and the full re-panel separately so the decision is made on real numbers rather than a single lump sum.

Workmanship

Five years on our labor for a full commercial system, in writing, with the covered scope stated. Repairs and partial scopes carry a shorter term and the contract says which one you bought.

Manufacturer system warranties

No-dollar-limit system warranties of 15 to 20-plus years where the building and the scope qualify, installed by a certified crew with a manufacturer field inspection. We tell you whether yours qualifies before you budget around it.

Closeout package

Product data, warranty registrations, core-cut and moisture findings, permit where one applied, and completion photographs. For an owner with several San Marcos properties, this is what makes the next roof easier to plan.

Commercial Roofing Contractor San Marcos TX FAQ

Common questions about this service.

Don't see your question? Call us at (512) 900-1054 — we're happy to talk it through.

Does a commercial re-roof need a permit in San Marcos? +

Often not, and the rule is unusual enough to be worth reading carefully. Ordinance No. 2023-09 removed IBC Section 105.2 exemption #2 and added exemption #14: roof covering replacement permits are not required unless the weight of the replacement roof is heavier than the existing roof covering. The trigger is weight — not material, not layer count. A membrane-for-membrane replacement is exempt on the face of the rule. Going to a substantially heavier assembly is not. Because the ordinary re-roof is exempt, the city publishes no re-roof permit fee line, so for a heavier assembly we confirm the fee with Planning and Development Services at (512) 393-8000 before it goes on your contract.

Which codes does San Marcos enforce? +

The 2021 I-Codes across the board — IBC, IRC, IECC, IFC, IPC, IMC, IFGC, IPMC, ISPSC and IEBC — plus the 2020 National Electrical Code, adopted by Ordinance No. 2023-09 on second reading 7 February 2023. The city's website states an effective date of 1 April 2023 while the ordinance ties effectiveness to charter publication; we report both rather than pick one. Worth knowing: San Marcos adopted no roofing technical amendments at all. Wind design, ice barrier, underlayment, re-cover limits, sheathing, fastening, drip edge and ventilation are all governed by the unamended code.

Do you have to register with the city as a roofing contractor? +

No, and we would rather you hear it from us than assume otherwise. San Marcos registers only specific state-licensed trades — building, plumbing, mechanical, irrigation, electrical and swimming pool. Roofing is not on the list, and Texas does not license roofers at state level either. That means the City is not screening your roofer for you in San Marcos. Ask for the certificate of insurance, ask how long the company has held the same name and address, and ask who is actually on the roof.

Can we use any dumpster company? +

No. San Marcos requires that all solid waste haulers operating within city limits obtain and maintain a valid commercial hauler permit, and commercial properties must contract disposal with an approved hauler. A roofer cannot simply bring an out-of-town roll-off company into the city. We verify the hauler's permit status before mobilization. It is a small thing that becomes a large thing when a box gets red-tagged on your parking lot mid-tear-off.

What are San Marcos's site rules during construction? +

More specific than most cities'. The adopted code requires a method of containment for construction debris on every site, regular removal so the site stays clean and safe, adequate sanitary facilities for workers, adjacent streets kept free of dirt and debris, and an express prohibition on sweeping or washing debris into unprotected storm water conveyance systems. The Building Official also approves staging areas where site constraints affect surroundings, and approves truck routes within city limits. We plan to all of it.

How much storm exposure does San Marcos have? +

Hays County logged 27 distinct hail days and 19 damaging-wind days across the eleven years from 2015 through 2025. Hail peaks decisively in April — 12 of 27 days — while wind peaks in May. Two years, 2018 and 2022, recorded no severe hail day at all, so this is not an annual cadence. The defining event of the period was 9 May 2024: three-inch hail at San Marcos Academy and at Mt Gaynor, 70 mph gusts, one report explicitly noting a damaged church roof in San Marcos, and $750,000 in costs to the City itself.

Is a reflective roof required here the way it is in Austin? +

No. San Marcos adopts the 2021 IECC with no local roof-reflectance or cool-roof amendment that we could find in the adopted ordinance text. Austin's steep-slope reflectance rule — 0.35 solar reflectance or SRI 29 above 2:12 — is an Austin ordinance and does not reach Hays County. A reflective membrane is still usually the right engineering choice here on energy grounds; it just is not a legal requirement.

We own several student-housing buildings. Can you handle a portfolio? +

Yes, and San Marcos is exactly the market for it — more than half the housing stock sits in buildings of three units or more. We survey the whole portfolio, rank the roofs by remaining service life rather than by which one complained loudest, and give you a phased plan with budget figures you can take to an owner or a board. Then we work the plan building by building around the academic calendar.
