Asphalt shingle roofing in Lewisville, TX
Asphalt shingle roofing covers most houses here. How it goes on decides how long it lasts.
One photo of the roof usually settles the layer count and the grade.
Asphalt shingle roofing in Lewisville, TX sits on most of the town
Asphalt shingle roofing in Lewisville, TX is what almost every house here wears, and the reasons are practical: it suits any slope, it repairs simply, and it costs less than every alternative. What varies enormously is how it is installed, and that is what separates a roof that reaches its rated life from one that does not.
Nailing pattern, starter course, valley treatment and ventilation are all invisible from the street a year later. All four decide whether the roof lasts.
- Nailed correctly: the right number, in the nail zone, at the right depth
- Started correctly: a proper starter strip at eave and rake, not a reversed shingle
- Vented correctly: intake and exhaust balanced, because heat ages shingles from beneath
Deck, underlayment, starter, field, ridge - the order on a Lewisville roof
The assembly as a sequence, which doubles as a checklist to hold a quote against. A quote that skips a line here is quoting a different job.
- 01Deck
- Inspected with the old roof off, and bad sheathing replaced against the estimate's allowance. Ask what the allowance covers and what a sheet beyond it costs.
- 02Ice-and-water and underlayment
- Membrane at valleys and penetrations, synthetic underlayment across the field. Felt is still permitted and still tears where synthetic holds.
- 03Drip edge
- Metal at eave and rake, under the underlayment at the eave and over it at the rake. Reversing that order sends water in behind the fascia.
- 04Starter course
- A purpose-made starter strip with its adhesive at the edge. A reversed shingle is the common shortcut and it fails at the perimeter.
- 05Field shingles
- Laid to the manufacturer's offset, nailed in the nail zone, with the count the specification calls for. Wind ratings assume that count, and a nail short voids them.
- 06Ridge and vents
- Ridge cap over a vented ridge, with penetrations flashed rather than caulked. Caulk at a penetration has a service life measured in seasons.
The installation and its workmanship warranty belong to the roofer; the material warranty comes from the manufacturer.
An install day in Lewisville, from the first tear-off to the last nail
How a typical single-family replacement runs. Weather sets the date and the roofer sets the crew. The shingle line itself is compared on the shingle page, and set beside the alternatives in the materials guide.
Protection, then tear-off
Landscaping and drive covered, dumpster placed, and the old roof stripped. On most houses the tear-off is a morning.
Deck inspected and repaired
Soft or delaminated sheathing replaced while it is visible, counted against the allowance in the estimate.
Dry-in and shingles
Underlayment down before anything else, then starter, then the field worked up the slopes.
Ridge, cleanup, magnet
Ridge vent and cap finished, debris removed, and a magnet run over the drive and lawn for nails.
What an asphalt roof looks like near the end
Asphalt gives plenty of warning if anyone is looking. Several of these together usually means it is time to price a roof replacement instead of another repair.
- Granules gathering at the downspouts every time it rains
- Tabs that curl at the corners or lift by hand
- Bald patches where the mat shows through the surface
- Shingles that crack instead of flexing on a warm day
- A roof that reads patchy in color from the street
Why two asphalt quotes on one street can differ
Neighboring houses of the same size can carry quotes a long way apart. The gap is usually in the parts nobody looks at, which is why an itemized estimate is worth more than a headline number.
Get an itemized quote- Shingle line: three-tab, architectural or impact-rated, which is the biggest single lever
- Layers: how many come off, which changes labor and disposal together
- Decking: the allowance included, and the rate for sheets beyond it
- Ventilation and details: whether the quote fixes the ventilation or just re-covers it
The 1990s build wave put the same roof on much of Lewisville
A great many houses in the middle of town went up within a few years of each other, and the roofs went on with the houses. Whole streets therefore reach the end of a covering together, which is why a run of tear-offs down one block is ordinary.
That pattern is worth knowing when a neighbor has one done. It often means yours is the same age, rather than that anything is wrong with your roof today.
- 01Same decade, same roof
- Houses built together were roofed together, and second coverings tend to follow the same clock.
- 02Thirty years on
- An original or first-replacement asphalt roof from that wave is now at or past its rated life.
- 03Hail on top of age
- Denton County records damaging hail most springs, which shortens what was already a finished roof.
Housing figures come from census data for Lewisville.
