Plain-English definitions of the 60 most common roofing terms Central Florida homeowners encounter in quotes, insurance claims, and inspection reports. Maintained by Matata Roofing — licensed FL CCC1337212.
A laminated asphalt shingle (also called dimensional or composite) with two or more layers bonded together. Standard on most Central Florida roofs because it is wind-rated to 130+ mph and carries 30-50 year manufacturer warranties.
An older, single-layer asphalt shingle with three uniform cutouts. Cheaper than architectural but rated for lower wind speeds; rarely installed in Florida today.
The water-resistant membrane installed directly over the roof deck and beneath the shingles, tile, or metal panels. Florida code requires a secondary water barrier (self-adhered or synthetic) under the primary underlayment.
A peel-and-stick membrane applied directly to the roof deck seams. Required by Florida code on re-roofs and a major factor in lower wind-insurance premiums.
The plywood or OSB substrate nailed to the trusses that supports underlayment and roofing material. Florida re-nailing code (FBC-EB 706.7) requires the deck to be re-fastened with 8d ring-shank nails at 6 inches on center during any re-roof.
Required upgrade during every Florida re-roof: existing deck must be re-fastened with 8d ring-shank nails at 6-inch spacing. Triggers a separate wind-mitigation credit on most homeowners insurance policies.
A metal flashing installed along the eaves and rakes to direct water off the deck and into the gutter. Florida code requires drip edge on all re-roofs.
The internal angle where two roof planes meet. The most common failure point for leaks in Central Florida; typically lined with metal (open valley) or a heavy ice-and-water shield (closed valley).
The horizontal peak where two roof slopes meet at the top. Covered with ridge cap shingles or a metal ridge cover.
A continuous vent along the roof ridge that exhausts hot attic air. Paired with soffit intake vents to create balanced attic ventilation.
Intake vents installed in the underside of roof overhangs that allow cool outside air into the attic. Required for proper attic ventilation in Florida's humid climate.
Sheet metal pieces installed at roof penetrations, walls, valleys, and chimneys to prevent water intrusion. Improper flashing is the #1 leak cause Matata sees in Central Florida.
L-shaped metal pieces interwoven with shingles along a wall-to-roof intersection. Each piece 'steps' up the slope with each shingle course.
A rubber or lead flashing that seals around plumbing vent pipes penetrating the roof. EPDM rubber boots fail in 8-12 years under Florida UV; lead boots last 30+ years.
A self-adhered bituminous membrane used in valleys, around penetrations, and along eaves. In Florida it doubles as the secondary water barrier and hurricane defense.
The first course of shingles installed along the eave, with adhesive pre-applied to seal the bottom edge of the first visible shingle course against uplift.
Specially cut shingles installed over the ridge and hips. Matching ridge cap is critical for both warranty and uplift resistance.
The vertical board mounted to the ends of the rafters along the eave. Gutter is fastened to it.
The horizontal underside of a roof overhang. Houses soffit vents for attic intake airflow.
The triangular wall section under the two sloping edges of a pitched roof. A gable roof has two slopes meeting at a ridge with gables on each end.
A roof with slopes on all four sides meeting at a ridge or peak. Earns a significant wind-mitigation insurance credit in Florida vs. gable roofs.
The slope of the roof expressed as rise over 12 inches of run (e.g., 6/12 = 6 inches of rise per 12 inches of run). Steeper pitches cost more to install due to safety equipment and labor.
A roofing unit of measure equal to 100 square feet. A typical 2,000 sq ft Central Florida home has about 22-28 squares of roof surface depending on pitch.
Complete removal of all existing roofing material down to the deck before installing new roofing. Florida code prohibits more than one layer of shingles, so tear-off is required on most re-roofs.
Installing new shingles over an existing single layer of shingles. Generally not recommended and prohibited in many Florida jurisdictions; voids most manufacturer warranties.
A Florida-specific inspection that documents roof features (deck attachment, secondary water barrier, roof-to-wall connection, roof shape, opening protection) used to calculate homeowners insurance discounts. Matata can coordinate this with your inspector.
How the roof trusses are attached to the wall (toe-nail, clips, single wraps, double wraps). Documented during wind mitigation; double wraps earn the largest insurance credit.
Hurricane shutters, impact-rated windows, or impact-rated garage doors. Listed on wind-mitigation reports for insurance discounts.
The lifting force that wind exerts on a roof surface. Shingle wind ratings (e.g., 130 mph) describe the speed at which uplift exceeds the shingle's bond strength.
Manufacturer-certified wind speed a shingle can resist when installed per specification. Standard Florida specs require 130 mph minimum; coastal Brevard/Volusia jobs typically use 150 mph product.
Roofing made from steel, aluminum, or galvalume panels. Two main styles: standing-seam (concealed fasteners) and exposed-fastener (5V crimp or R-panel). 40-70 year service life in Florida.
A metal roof system where adjacent panels are joined by raised vertical seams crimped together. No exposed fasteners on the panel face — the most durable and weather-tight metal option.
An exposed-fastener metal panel with two pairs of small ribs plus a center rib (looks like 5 V shapes). Cheaper than standing-seam; common on Old-Florida cottage styles.
Roofing made from concrete or clay tiles. 50+ year service life but heavy (requires engineered structure) and slower to install. Common on Mediterranean and Spanish-style Central Florida homes.
Cement-based tile, less expensive than clay, available in flat, low-profile, and high-barrel (S-tile) shapes.
Fired terra-cotta tile. Longest service life of any roofing material (75-100 years) and the most expensive.
A torch-down or self-adhered low-slope roofing membrane. Common on Florida flat roof sections, lanais, and additions.
Thermoplastic polyolefin single-ply membrane for low-slope and flat roofs. Reflective white surface reduces cooling load on Florida buildings.
Black rubber single-ply membrane for low-slope roofs. Less common in Florida than TPO due to heat absorption.
The raised wood frame a skylight sits on, flashed into the surrounding roof. Re-flashing skylights during a re-roof is standard Matata practice.
A small peaked structure built behind a chimney to divert water around it. Required by code on chimneys wider than 30 inches.
A small piece of flashing at the bottom of a roof-to-wall intersection that kicks water away from the wall and into the gutter. Frequently omitted — a major hidden leak source.
Not applicable in Florida (no freeze cycle); included for context when relocating from northern climates.
Aerial photographic inspection of a roof using a UAV. Matata provides this free on every estimate with full photo report sent to the homeowner — no foot traffic or climbing required.
Infrared scan of a roof to detect wet insulation or trapped moisture. Common on commercial low-slope roofs.
Temporary heavy-duty tarp installation after storm damage to prevent further water intrusion until permanent repair. Matata responds 24/7 across Central Florida.
Additional scope or pricing submitted to your insurance carrier after the initial estimate. Most partial-pay denials can be supplemented into a full replacement with proper documentation.
The amount your insurance policy pays to replace your roof at today's prices, without depreciation. Differs from ACV (Actual Cash Value) which deducts depreciation.
Insurance payout that deducts depreciation from RCV. As of 2022, Florida law limits ACV-only roof policies to roofs older than 25 years on most carriers.
A separate, higher deductible (typically 2-5% of dwelling value) that applies only when a named hurricane causes the loss. Standard on every Florida homeowners policy.
A contract that signs your insurance benefits over to a contractor. As of 2022 Florida law has largely eliminated AOB on roofing claims — Matata never asks homeowners to sign AOB.
The line-item document an insurance adjuster writes describing every component of the damage and the price they'll pay for each.
Florida law that requires insurers to pay for replacement of undamaged materials when matching ones are no longer available. Often used to convert partial-roof claims into full replacements.
Permit pulled with the local jurisdiction (city/county) for any re-roof. Matata pulls every permit in our name and handles the inspection.
The specified number and placement of nails per shingle. Florida high-velocity hurricane zones require 6 nails per shingle; the rest of Central Florida requires 4 or 6 depending on wind zone.
An enhanced warranty (typically 25-50 years) available when the roof is installed by a manufacturer-certified contractor using matched system components. Covers materials and labor for the warranty period.
Shingles with copper-infused granules that prevent black streaking from Gloeocapsa magma algae. Standard upgrade in humid Central Florida.
Reflective shingles certified by the Cool Roof Rating Council. Can qualify for Florida energy rebates and reduce attic temperatures by 10-20°F.
A covered outdoor living-space roof, often low-slope and tied into the main house roof. Frequently the source of leaks where it joins the main roof.
Accelerated rust and degradation from coastal salt aerosol. Matata uses stainless or coated fasteners and aluminum flashing on Brevard, Volusia, and coastal Polk jobs.
Typical service life for Central Florida roofs: 3-tab shingle 12-15 yr, architectural shingle 18-25 yr, standing-seam metal 40-60 yr, concrete tile 50+ yr, clay tile 75-100 yr. Florida UV and storms shorten northern-climate ratings by ~20%.
