Layering over old shingles
It saves on disposal and adds weight, hides deck problems and shortens the new roof’s life. Any hidden damage underneath goes unfixed.
Asphalt shingles cover the large majority of American homes for good reasons: they are affordable, repairable, widely available and genuinely durable when the assembly under them is done properly.

Shingle roofs fail for predictable reasons, and almost none of them involve the shingle itself. Underlayment that was inadequate or has aged out, flashing that was reused, ventilation that traps heat and moisture, and nails placed high or overdriven account for the great majority of early failures we are called to.
Whether you are repairing a slope, upgrading the material or replacing the whole roof, the value is in the system: membrane at the vulnerable areas, proper fastening, correct exposure and a ventilation path that lets the deck dry.
Asphalt shingles come as 3-tab (flat, uniform, the value option), architectural or dimensional (thicker, laminated, the market standard) and impact-rated Class 4 (reinforced mat, engineered for hail). Under them sit the layers that decide how long the roof lasts: underlayment, ice-and-water membrane at eaves and valleys, and the flashing details.
Warranty duration is a marketing number. What actually determines service life is the mat thickness, the sealant quality, the fastening pattern, ventilation and how the roof is detailed at its penetrations.
| Option | What it is | Relative cost |
|---|---|---|
| 3-tab | Thin, flat profile. Cheapest, shortest life, best for rentals and outbuildings. | lowest |
| Architectural / dimensional | The mainstream choice: thicker mat, laminated construction, 25–30 years and better wind ratings. | standard |
| Class 4 impact-rated | Reinforced mat engineered for hail, frequently qualifying for insurance premium discounts. | standard plus |
| Premium / designer | Heavyweight laminated shingles and synthetic slate looks for design-led projects. | premium |
The same sequence every time, because it is the sequence that protects you: evidence first, price second, work third, documentation last.

Shingle options with honest differences: life expectancy, wind rating, hail performance and cost.

Warranty registration in your name, site magnet-swept, final walkthrough completed.
These are the failure patterns we are called in to correct most often — usually after someone else was paid to do it once already. Knowing them is the best protection you have when comparing quotes.

The most common omission in low bids in cold and hail markets. It costs little at installation and cannot be added later without tearing the roof apart.
Without intake at the eaves, ridge ventilation cannot function. The deck cooks, shingles age faster, and in cold climates ice dams form.
High nails, overdriven nails and too few nails per shingle are invisible from the ground and are the leading cause of wind damage.
Installed asphalt roofing generally runs from roughly $450 to $900 per square (100 sq ft) for an architectural shingle system, depending on pitch, layers, access and detailing. A typical 1,700–2,400 sq ft home therefore lands in the range of about $8,500 to $22,000 for a full replacement, with repairs considerably lower.
Impact-rated shingles add a premium up front that can be partly offset by insurance discounts in hail-prone states; ask your carrier what they offer before choosing.
Shingle work is what our crews do most, and it is where the difference between a specification-grade install and a rushed one shows up within five years. We install the membrane and ventilation details that low bids quietly leave out, and we show you photographs of both before the roof is closed up.
Crews are dispatched to Lakeway, Texas and the surrounding communities through our network of licensed, insured roofing contractors, with dispatch priority published for every market we cover. That means small towns get a real crew instead of a three-week wait or no quote at all — the trade-off is that some extended-coverage areas are served on a rotating route, and the dispatcher will tell you honestly which one your address is in.
Lakeway is one of hundreds of markets where we run this work, and every one of them has its own page listing covered ZIP codes, local roof stock, climate pressures and the neighbouring areas we also serve.
Prefer to start from the state? Each page below covers shingle roofing locally — what the work involves in that climate, what the local roof stock looks like and which cities we serve there.
Everything below is handled by the same crews. Contextual links, not a keyword list — pick whichever one describes your problem.
In practice, 3-tab often reaches 15–20 years and architectural 20–30, with the variation driven more by ventilation, sun exposure and storm history than by the warranty number. A badly ventilated roof in a hot climate can fail years early.
In hail-prone regions, usually yes. They resist bruising far better, and many insurers offer a premium discount that recovers part of the premium over time. In areas with almost no hail risk, a good architectural shingle is the better value.
Often yes, where the rest of the roof has useful life left and the tie-in can be detailed cleanly. If the shingle line is discontinued, expect a visible difference in that area, and consider a design detail to make it look intentional.
It is a gloeocapsa magma algae that feeds on limestone filler in asphalt shingles, and it is cosmetic but unsightly. Copper or zinc strips near the ridge inhibit it, and algae-resistant shingles are available for replacement. Never pressure wash a shingle roof — it destroys the granules.
Yes — Lakeway is inside our coverage area and crews are routed to that market on a published dispatch priority. Call (858) 779-8014 and the dispatcher will confirm scheduling for your address and give you a realistic window rather than a marketing one.
Installed asphalt roofing generally runs from roughly $450 to $900 per square (100 sq ft) for an architectural shingle system, depending on pitch, layers, access and detailing. You get a written price before any work starts, and anything discovered mid-job is priced, photographed and approved by you rather than added to an invoice at the end.
One call gets you a real answer: whether what you are describing is shingle roofing work, what it is likely to cost in Lakeway, and how soon a crew can be at your address.
