Metal Roof Over Shingles (Retrofit) San Angelo

Metal Roof Over Shingles (Retrofit) in San Angelo: Keep Your Shingles, Gain a Metal Roof

San Angelo sits at about 1,900 feet on caliche and limestone along the Concho River, and the sun here does not negotiate. On the 1950s to 1970s brick and stone ranch homes across Glenmore, Lakeview and Rio Concho, the original low-pitch composition shingles have baked through decades of triple-digit summers and spring hail that pocks the mat. A Metal Roof Over Shingles (Retrofit) in San Angelo lets you put a metal roof directly over that existing shingle layer, with no tear-off, less landfill waste and a lower invoice than a full replacement. We check the deck and the existing layers first, and we tell you straight when a tear-off is the better call. If you are still weighing panel types, start with our metal roof installation overview, then come back to the retrofit path. This is a working roof over a working roof, done to code and built for West Texas hail.

Why Retrofit Over Shingles Makes Sense on San Angelo's Ranch Homes and Lake Cottages

The building stock here is the argument. Those low-pitched ranch roofs across Glenmore and Lakeview were framed for shingle weight, and a retrofit adds a metal skin without a dumpster in the driveway for a week. Around Lake Nasworthy, cottages that see UV off the water and wind-driven rain benefit from a continuous metal plane over the old shingles. Out toward Grape Creek, Christoval and Wall, ranchettes and shops already wear metal for the same reason: it shrugs off hail and sun.

You skip the tear-off labor and the dump fees, which keeps the project cost down on a typical 1,800 to 2,400 sq ft ranch home.
You add a second barrier over the old shingles, which helps on low-slope sections that have already seen water push under worn tabs.
You cut the heat load on the attic, which matters when July afternoons sit above 100 degrees for weeks.
You keep the house weather-tight during the job instead of opening the deck to the sky.

Code sets a limit on how many existing shingle layers you can cover, so the first step is always counting what is up there and checking the deck for soft spots.

Key info: A 1962 brick ranch off Rio Concho Drive had one layer of original shingles and solid 1x6 decking. We retrofitted a standing seam panel over it in three days with no tear-off. A 1958 home near Santa Rita had two layers plus rotted decking at the valley, and we recommended a full tear-off instead. The deck decides the path, not the sales pitch.

Roofing permits are commonly required for a re-roof in San Angelo and Tom Green County, and the local building department sets the layer limits and inspection rules, so verify the current requirements before work starts at the City of San Angelo.

How We Retrofit a Metal Roof Over Shingles in San Angelo, Step by Step

We do not sell a retrofit before we have been in the attic and on the roof. The sequence below is what a San Angelo job looks like from the first walk-through to the final sweep, and it is the same whether you are in Bentwood or out on a ranchette toward Mertzon.

We inspect the existing shingle layers, the decking, the attic ventilation and every penetration before quoting.
We confirm the layer count against code and pull the permit through the local building department.
We fasten a purlin or batten system or screw through to the deck, depending on the panel profile and the deck condition.
We install underlayment and new flashing at the chimney, skylights and wall transitions so water never gets between the two roofs.
We set the panels, run the trim and ridge, and seal the fasteners to spec.
We walk the roof with you, hand over the paperwork and magnet-sweep the yard for screws.

Every step is documented, because hail claims in Tom Green County live or die on paperwork.

Local example: On a 1971 brick home in Lakeview with a 4/12 pitch, we ran battens over the single shingle layer, installed a stone-coated steel panel and re-flashed the original furnace vent. The homeowner kept the shingles in place, saved the tear-off cost and gained a hail-rated roof. If your home is in the 76903 or 76901 ZIP, see the 76903 retrofit page for neighborhood specifics.

Retrofit Approaches We Use Across San Angelo

Not every panel goes over shingles the same way. The right approach depends on pitch, deck condition, layer count and the look you want on a brick ranch versus a lake cottage. Here is how the main options compare on San Angelo homes.

Approach	Description	Best for
Batten over single shingle layer	Wood battens screwed to the deck create a drainage plane under the panels.	1950s to 1970s ranch homes with one layer and sound decking.
Direct fasten with underlayment	Synthetic underlayment over the shingles, then panels screwed through to framing.	Simple gable roofs with good deck and easy access.
Standing seam over shingles	Concealed fasteners and raised seams on a batten system.	Homeowners who want the cleanest look and fewer exposed screws.
Exposed fastener panel over shingles	Corrugated or ribbed panel screwed through to the deck.	Shops, barns and budget-minded retrofits out toward Wall and Christoval.
Tear-off and full replacement	Remove all shingle layers, repair deck, then install metal.	Two or more layers, soft decking or heavy hail damage.

We match the approach to the house, and we will not sell a retrofit onto a deck that cannot carry it.

Metal Roof Over Shingles (Retrofit) Cost in San Angelo: What to Expect

Retrofit pricing starts around $7 per square foot for a straightforward panel over a single shingle layer, and that figure is a starting point, not a quote. On a 2,000 sq ft roof, that puts the low end near $14,000, while standing seam, complex hips and valleys, or two-story access push it higher. The deck condition is the biggest swing factor: soft sheathing at a valley means repair before any panel goes down.

Roof size and pitch drive the square footage and the labor hours.
Panel type matters: exposed fastener costs less than standing seam or stone-coated steel.
Existing layer count and deck repairs can add or even force a tear-off.
Flashing work at chimneys, skylights and wall transitions is priced by the piece.
Access and height, including two-story homes in Bentwood, add setup time.

Frequently asked questions: Metal Roof Over Shingles (Retrofit) in San Angelo

Can you put a metal roof over shingles in San Angelo without tearing off the old roof?

Yes, on many San Angelo homes, as long as the existing shingle layers are within the code limit and the deck is sound. We inspect the attic and the roof surface first, count the layers and check for soft sheathing at valleys and penetrations. If the deck is failing or there are too many layers, we tell you a tear-off is the better path. The decision is made on the deck condition, not on what is easier to sell.

How much does a metal roof over shingles cost in San Angelo?

Retrofit pricing starts around $7 per square foot for an exposed fastener panel over a single shingle layer. A typical 2,000 sq ft ranch home lands near $14,000 at that rate, while standing seam or stone-coated steel runs higher. Deck repairs, flashing work and two-story access add to the number. Get two or three written estimates with the same scope before you commit.

How do you fasten a metal roof over existing shingles?

We either run wood battens screwed to the deck and fasten the panels to the battens, or screw the panels through the shingles into the framing, depending on the panel profile. A synthetic underlayment goes down first so water has a path out. On standing seam, the battens create the drainage plane and the fasteners stay concealed. We follow the panel manufacturer's fastening schedule for wind uplift.

How long does a metal roof over shingles job take in San Angelo?

A straightforward 2,000 sq ft ranch home with one shingle layer takes about two to four days once materials are on site. Complex roofs with multiple hips, valleys and skylights run longer. Standing seam takes a bit more time than exposed fastener because of the batten system and seaming. We give you a realistic schedule in the estimate and update you if the deck turns up surprises.

Do I need a permit to put a metal roof over shingles in San Angelo?

Roofing permits are commonly required for a re-roof in San Angelo and Tom Green County, and the rules on layer limits and inspections vary. We confirm the current requirements with the local building department before work starts. If your home is in a historic district or a deed-restricted subdivision, design review may also apply to panel profile and color. We handle the paperwork and meet the inspector on site.

What is the difference between a metal roof retrofit and a full metal roof replacement?

A retrofit installs new metal panels over the existing shingles without tearing them off, which saves labor and dump fees. A full replacement removes all shingle layers down to the deck, repairs any sheathing and starts fresh. Retrofit is faster and cheaper when the deck is sound and the layer count is within code. Replacement is the right call when there are two or more layers or the deck has rot.

What is the best time of year to retrofit a metal roof in San Angelo?

Spring and early summer bring the supercells and large hail that pock old shingles, so demand spikes right after a storm. Late summer and fall are the steadiest window: the triple-digit heat breaks and crews can work full days without heat delays. Winter is mild here with only an occasional light dusting of snow, so retrofits run year-round. The dominant failure mode in this city is hail damage to aging shingles, so do not wait past a bad spring.

Do you handle emergency metal roof over shingles work in San Angelo?

Yes. If a storm has opened your roof or a section is failing, call (325) 468-8736 and we will get a crew out to tarp and stabilize the roof, usually the same day or the next morning. We document the damage for your insurance file and then schedule the retrofit or repair. We never promise coverage, but we give you the photos and paperwork your adjuster needs.

Is the estimate really free and no-obligation?

Yes. We come out, inspect the attic and roof, count the shingle layers and check the deck, then give you a written estimate with the scope spelled out. There is no charge for the visit and no pressure to book. If the deck points to a tear-off instead of a retrofit, we tell you that and quote it honestly. You can take the estimate and compare it with other contractors.

Are you licensed and insured for metal roof retrofits in San Angelo?

Yes. Ask for it and call the carrier to confirm the policy is active. We also pull the required permits through the local building department and meet the inspector on site. Licensed and insured is the baseline, not a selling point.
