Roof Materials & Anatomy
19 termsShingle
The individual overlapping pieces — almost always asphalt-based in Florida — that make up a roof's visible outer layer. Rated for wind speed and usually priced by the “square” (see Pricing & Contract Terms).
Architectural / Dimensional Shingle
A heavier, multi-layer shingle style — thicker and more textured than a flat “3-tab” — that generally carries a higher wind rating and a longer warranty.
3-Tab Shingle
The flattest, lightest, least expensive shingle style: one uniform tab per shingle. Lower wind rating than architectural/dimensional, and it shows — a flatter, more uniform look on the roof.
Decking (Roof Deck / Sheathing)
The plywood or OSB panel nailed across the roof trusses that everything else attaches to. If it's rotted or soft under the old shingles, a tear-off is the only way to find out — and the only way to actually fix it.
OSB
Oriented Strand Board — an engineered wood panel made of compressed wood strands, commonly used for roof decking as a cost-effective alternative to plywood.
Underlayment
The moisture barrier installed directly on the deck, underneath the shingles. Modern peel-and-stick underlayment self-seals around nail penetrations, which old-style felt paper never did.
SWR (Secondary Water Resistance)
A sealed, self-adhering underlayment applied across the entire deck, not just the seams. It's also a recognized Florida wind-mitigation credit — meaning it can lower a homeowner's insurance premium, not just improve leak protection.
Flashing
Metal (sometimes rubber) strips installed at roof edges, valleys, and around penetrations like chimneys and vents to route water away from seams — one of the most common places a roof actually leaks.
Granules
The small mineral chips embedded in the top layer of an asphalt shingle, protecting it from UV damage. Finding a few in the gutters is normal aging; finding a lot, fast, usually isn't.
Gutters & Downspouts
The channel system that collects roof runoff and carries it away from the foundation. Damaged, sagging, or clogged gutters can let water back up under the roofline instead of away from the house.
Roofline
The visible edge where the roof meets the walls of the house — where flashing, gutters, and fascia all meet, and a common spot for the earliest leak signs to show.
Attic
The space directly beneath the roof deck. Its condition — moisture, staining, insulation — is often the fastest way to spot storm damage or a slow leak before it ever reaches the living space below.
Insulation
Material in the attic that regulates heat transfer between the roof and the living space. Wet or compressed insulation is often the first physical evidence of a hidden roof leak.
Ventilation
The intake/exhaust system — ridge vents, soffit vents, and the like — that lets attic heat and moisture escape. Poor ventilation traps heat against the underside of the roof and shortens shingle life.
Slope / Pitch
How steep a roof is, expressed as a ratio of rise to run. Pitch affects material choice, drainage speed, and labor — a “low-slope” roof needs different materials and methods than a steep one.
Chimney
A common leak point on any roof — the flashing seal where a chimney penetrates the deck ages faster than the surrounding shingles and should get checked on every inspection.
Curling
Shingle edges lifting or turning upward, usually from age or heat exposure — an early, visible sign a section of roof may need replacing, not just a spot repair.
Staining / Moisture
Discoloration on the underside of the deck or in the attic — usually the first visible evidence of a leak, even while the shingles above still look fine. Moisture with no visible staining yet is the earliest, cheapest stage to catch a problem.
Debris
Branches, granules, or storm litter resting on or against the roof. Left alone, it traps moisture against that spot and speeds up wear right where it's sitting.
Installation & Workmanship
7 termsTear-Off
Removing the old roof completely down to the deck before installing a new one, instead of layering new shingles over old. Costs more up front, but it's the only way to actually inspect — and if needed, replace — the deck underneath.
Re-Roof
Replacing the entire roof system rather than patching one section — the right call once damage or wear is spread across the roof (system-wide) instead of confined to one isolated spot.
Job-Site
Wherever the actual work happens. Relevant to a homeowner mainly around workers' compensation — coverage that protects you if someone is hurt performing work at your home.
Workmanship
The quality of the labor itself, separate from the materials used. A workmanship warranty covers mistakes made during installation — a different thing from a manufacturer's material warranty (below).
Warranty
A written guarantee against defects. Roofing has two kinds that get confused constantly: a manufacturer's material warranty (covers the shingles themselves) and a contractor's workmanship warranty (covers how they were installed). Always ask which one — or both — you're actually getting, and for how long.
Transferable (Warranty)
A warranty that can be passed on to a new owner if the home sells during the warranty period — real resale value, not just protection for the current owner.
Wind Rating
A product's tested performance against wind uplift — e.g. a shingle “rated” for 130 mph. Higher-rated materials usually cost more, and in Florida that difference isn't cosmetic.
Storm & Wind Mitigation
1 termsWind Mitigation
An inspection that documents storm-resistant features of a home — roof shape, deck attachment, opening protection, SWR (see Materials). Florida insurers use it to calculate real premium discounts, so it's paperwork that can actually save money, not just a formality.
Insurance & Claims
4 termsInsurance Claim
A formal request to your insurance company to pay for storm or damage-related repair or replacement — typically starting with an inspection and a written estimate, not a verbal number.
Insurance Adjuster
The person your insurance company sends to evaluate a claim and decide what it will pay. A public adjuster, by contrast, works for the homeowner, not the carrier — Florida law treats the two roles very differently, and they are not interchangeable.
Carrier / Insurer
Industry shorthand for your insurance company itself — the entity that issues the policy and pays (or denies) a claim.
Policyholder
The homeowner who holds the insurance policy — the person Florida law gives final authority over how a claim proceeds, not the contractor and not the adjuster.
Pricing & Contract Terms
11 termsItemized
Broken down line by line — materials, labor, disposal, and so on — instead of one lump number, so you can see exactly what you're paying for and compare it fairly against another quote.
Documentation
Photos, written estimates, and records tied to a specific job — the paper trail that supports both an insurance claim and an honest price comparison.
Estimate / Quote
A written, itemized price for the job before work starts — not a verbal number. It should specify materials, scope, and price, not just a total at the bottom.
Inspection
A physical walk-through of the roof — and usually the attic — to assess its condition. Normally the first step before either an estimate or an insurance claim.
Material / Labor
The two things every roofing price is made of: the products used (shingles, underlayment, decking, flashing) and the cost of the crew's work to install them. An itemized or cost-plus quote tracks the two separately.
Manufacturer
The company that actually makes the shingles or other products used on your roof — separate from the contractor who installs them. See Warranty for why that distinction matters.
Markup
The amount added on top of the real, documented cost of materials and labor. A fixed “$100 over cost” offer means the markup stays $100 regardless of job size, rather than a hidden percentage that grows with the price.
Lump-Sum
A single total price with no breakdown of materials, labor, or markup — harder to evaluate or compare fairly than an itemized quote.
Per-Square
A pricing method based on roofing “squares” — 100-square-foot units — rather than the whole job or individual line items. Common in the trade, but can make the final number harder to predict up front.
Per-Item
A pricing method that charges separately for each material or task rather than one whole-job number — the opposite tradeoff of a flat, all-in price.
Add-Ons
Extra charges that show up after work has already started, which weren't in the original quote — exactly what an itemized, upfront estimate is supposed to prevent.
Manufacturer Brands
3 termsGAF
One of the largest U.S. roofing shingle manufacturers. Like any major brand, GAF's material warranty terms are separate from — and don't replace — your contractor's own workmanship warranty. See our full GAF product-line breakdown.
CertainTeed
A major U.S. roofing and building-materials manufacturer, offering shingle lines across a range of price points and wind ratings. See our full CertainTeed product-line breakdown.
Owens Corning
A major U.S. roofing and insulation manufacturer. Like every brand in this category, its material warranty covers the product itself, not the quality of the installation. See our full Owens Corning product-line breakdown.
