Roof glossary — materials, tools, and terms.

Everything a roofer points at, in plain English. Photos of every material, the tools we actually carry up the ladder, and the vocabulary you'll hear in your estimate.

Roofing materials

Every system we install — what it is, what it lasts, where it shines.

Seven systems cover virtually every roof in the Albuquerque metro. Pictures, lifespans, and our honest take on each.

White TPO single-ply roof membrane with heat-welded seams on a flat commercial roof
Flat20–30 years

TPO (Thermoplastic Polyolefin)

What it is
A white single-ply plastic membrane rolled out in wide sheets and heat-welded at the seams. The reflective surface bounces sunlight instead of absorbing it.
Best for
Flat residential & commercial roofs
In the ABQ high desert
Our default flat-roof recommendation in ABQ. The white surface cuts attic temps 20–40°F in July and resists UV that destroys darker membranes.

Black EPDM rubber roofing membrane on a flat roof
Flat20–30 years

EPDM Rubber

What it is
A solid rubber membrane proven on flat roofs since the 1960s. Glued or fastened down, with seams joined by adhesive or tape.
Best for
Flat roofs where appearance doesn't matter (out of sight)
In the ABQ high desert
The black surface absorbs sun aggressively, so we use EPDM mainly for shaded flat roofs or where the customer specifically wants a proven, repairable membrane.

Modified bitumen torch-down roof with overlapping granulated rolls
Flat15–25 years

Modified Bitumen (Mod-Bit)

What it is
Asphalt-based sheet roofing in rolls. Torch-applied, cold-applied, or self-adhered. Often topped with mineral granules.
Best for
Flat roofs, parapet transitions, easy field repair
In the ABQ high desert
Very repairable — a torn patch can be re-melted in place. Pairs well with reflective coatings to fight UV.

Built-up tar and gravel roof with pea gravel embedded in asphalt
Flat15–25 years

Tar & Gravel (Built-Up Roof / BUR)

What it is
Layers of asphalt-saturated felt mopped together with hot asphalt, finished with a layer of gravel for UV protection and fire resistance.
Best for
Traditional ABQ flat roofs, big commercial fields
In the ABQ high desert
Classic Albuquerque flat roof. We still service hundreds of them, but most replacements today move to TPO or coated mod-bit for energy savings.

Architectural asphalt shingles in charcoal grey on a steep residential roof
Steep20–30 years

Architectural Asphalt Shingles

What it is
Asphalt-and-fiberglass shingles in overlapping rows. 'Architectural' (laminated) shingles add a second layer for shadow lines and a longer warranty than 3-tab.
Best for
Pitched residential roofs on a budget
In the ABQ high desert
Affordable and fast to install, but UV chews them up — we always spec a Class 4 impact-rated shingle with cool-roof granules in NM.

Terracotta clay barrel tile roof on a Southwest adobe home
Steep50+ years (tile) / 30 years (underlayment)

Clay & Concrete Tile

What it is
Individual baked clay or concrete tiles laid in overlapping rows. The tile sheds most of the water; the underlayment underneath is the real waterproof layer.
Best for
Southwest, Spanish, and Mediterranean homes
In the ABQ high desert
Iconic in ABQ neighborhoods. When tiles look fine but the roof leaks, the underlayment is usually toast — we can lift tiles, replace the underlayment, and re-lay 90%+ of the original tile.

Dark bronze standing-seam metal roof with raised vertical seams on a Southwest home
Steep40–70 years

Standing-Seam Metal

What it is
Long interlocking metal panels with raised, concealed-fastener seams running vertically up the slope. Steel, aluminum, copper, or zinc.
Best for
Long-term homeowners, mountain & East Mountain homes, fire zones
In the ABQ high desert
Premium cost, premium lifespan. Reflects desert sun, sheds monsoon downpours fast, won't burn in a wildland fire. Our top pick for 'forever' homes.

Tools of the trade

What's in the truck.

The hand tools, power tools, safety gear, and diagnostic kit a real roofing crew carries to every job.

Hand tools

Roofing hammer (hatchet)

Hammer with a built-in gauge to space shingles and a hatchet edge to score and cut.

Roofer's pry bar

Long flat bar with a notched head for pulling nails and lifting shingles during tear-off.

Tin snips

Hand shears for cutting flashing, drip edge, and metal panels — straight, left, and right cut variants.

Utility knife (hook blade)

Hook-blade knife for slicing through asphalt shingles cleanly without snagging.

Chalk line

Chalked string snapped against the deck to keep shingle and panel courses dead straight.

Seam roller

Hand roller used to press TPO and EPDM seams flat after heat-welding or adhesive.

Caulk gun

For sealants around flashing, pitch pockets, and penetrations.

Roofing shovel (tear-off shovel)

Wide blade with a serrated edge and built-in fulcrum for ripping off old shingles fast.

Power tools

Pneumatic nail gun (coil roofer)

Air-powered nailer that drives coil-loaded roofing nails — the workhorse of any shingle install.

Hot air welder

Handheld blower that fuses TPO or PVC membrane seams without flame.

Propane torch / kettle

Used to torch-down modified bitumen rolls — adheres the membrane as it melts the underside.

Leaf blower

Clears debris from valleys, scuppers, and gutters as the crew works.

Cordless impact driver

For driving deck screws, fastening metal panels, and securing flashing.

Safetys

Harness & roof anchor

OSHA-required fall protection above 6 ft — anchored to the structure, never to a vent.

Hard hat

Mandatory ground-side gear when crews are tearing off above.

Roof jacks (toe-board brackets)

Metal brackets nailed into rafters that hold a 2x6 plank for footing on steep slopes.

Magnetic sweeper

Wheeled magnet rolled across lawns and driveways after the job to pick up every dropped nail.

Tarps & ground covers

Heavy tarps over landscaping, A/C units, and pools during tear-off to catch debris.

Diagnostics

Survey drone

Flies the roof for a high-res orthomosaic — measure area, count penetrations, flag damage without walking fragile surfaces.

Infrared / thermal camera

After sundown, wet insulation glows differently than dry — finds trapped moisture under flat roofs.

Moisture meter

Probes through the membrane or scans the surface to confirm moisture readings from thermal imaging.

Inspection camera

We video every inspection — drone above, GoPro on the crew lead — so you see what we see.

Pitch gauge

Pocket tool that reads roof pitch in inches-per-foot, used to spec underlayment and warranty material.

Materials in the toolbox

Underlayment (synthetic / felt)

Waterproof sheet under the visible roofing — the real waterproof layer on tile, metal, and shingle roofs.

Ice & water shield

Self-adhered rubberized membrane at eaves, valleys, and around penetrations.

Drip edge

Metal trim along the roof edge that directs water into the gutter, not behind the fascia.

Pipe boots / vent flashing

Pre-formed rubber or lead collars that seal where plumbing vents and exhaust pipes penetrate the roof.

Roofing vocabulary

Plain-English term dictionary.

The words your roofer uses on estimates and invoices — defined without jargon.

Decking
The plywood or OSB layer your roof system is attached to, sitting on top of the rafters.
Drip edge
Metal trim along the roof edge that directs water into the gutter, not behind the fascia.
Eave
The lower edge of a sloped roof that overhangs the wall.
Fascia
Vertical trim board at the eave that the gutter attaches to.
Flashing
Metal pieces that seal transitions between the roof and walls, chimneys, or skylights.
Gable
The triangular wall section at the end of a pitched roof.
Hip
The external angle where two roof slopes meet — the opposite of a valley.
Ice & water shield
Self-adhered membrane installed at vulnerable areas — eaves, valleys, around penetrations.
Parapet
A low wall around the edge of a flat roof — common on pueblo-style architecture.
Penetration
Anything punching through the roof — vent stacks, skylights, HVAC curbs, solar mounts.
Pitch
How steep the roof is, measured as rise over 12 inches run (e.g. 4/12).
Pitch pocket
A small metal box filled with sealant around an oddly-shaped penetration.
Ponding water
Standing water on a flat roof more than 48 hours after rain. Bad sign.
Rafter
Structural framing member that runs from the ridge to the eave.
Ridge
The horizontal line at the top where two roof slopes meet.
Scupper
An opening in a parapet wall that lets water drain off a flat roof.
Soffit
The underside of the eave overhang — usually vented for attic intake air.
Square (roofing)
100 square feet of roof area — the unit estimators measure and price in.
Tear-off
Removing the existing roof down to the deck before installing the new system.
Underlayment
The waterproof layer between the deck and the visible roofing material.
Valley
The internal angle where two roof slopes meet. Water concentrates here.
