Shingle Roofs
Shingle Roofs
Shingle Roofs
Shingles are flat, rectangular pieces of asphalt, composite, or other roofing material; they're applied from the base of the roof upwards and often overlap to provide full coverage.
Slate Roofs
Shingle Roofs
Shingle Roofs
Genuine slate roof shingles are 100-percent natural stones with no additives. Like natural granite counters, slate roofing is quarried directly from the earth.
Built-Up Roofs
Built-up roof membranes (BUR), also called "tar and gravel" roofs, are composed of alternating bitumen layers and reinforcing fabrics that create a finished membrane. The number of plies in a cross-section is the number of plies on a roof: The term "four plies" denotes a four-ply roof membrane construction. Sometimes, a base sheet, used as the bottommost ply, is mechanically fastened. Built-up roofs are fully adhered if applied directly to roof decks or insulation. The reinforcing fabrics also are called roofing felts or ply sheets. Roofing felts are reinforced with either glass-fiber mats or organic mats. Felts are produced in a standard width of 36 inches and metric width of about one meter.
The bitumen typically used in BUR roof systems is asphalt, coal tar, or cold-applied adhesive. Asphalt is a petroleum product refined from crude oil; coal tar is derived from the distillation of coal. The asphalt or coal tar is heated in a kettle or tanker and then applied by mop or mechanical spreader. Cold-applied adhesives are solvent-based asphalts that don't have to be heated in a kettle or tanker. Surfacings for built-up roof systems include aggregate (such as gravel, slag, or mineral granules), glass-fiber or mineral-surfaced cap sheets, hot asphalt mopped over the entire surface, and aluminum coatings or elastomeric coatings.
A roof system composed of a built-up roof membrane with two or three plies and a polymer-modified bitumen membrane cap sheet is commonly called a "hybrid" system. NRCA considers this type to be a polymer-modified bitumen membrane system.
Modified Bitumen
Polymer-modified bitumen or modified bitumen (MB) sheet membranes were developed in Europe in the early 1960s and have been used in the U.S. since the mid-1970s. Polymer-modified roof membranes are composed of reinforcing fabrics that serve as carriers for the hot polymer-modified bitumen as it is manufactured into a roll material. MB roof system membranes are composed of multiple layers, much like BUR membranes. MB roof systems typically are installed as a two-ply system and almost always are fully adhered.
There are two types of MB roofing membranes:
- SBS polymer-modified bitumen membranes are commonly installed in hot asphalt moppings (similar to BUR systems) or cold adhesive. Some SBS-modified membranes are self-adhering; that is, they contain an adhesive backing.
- APP polymer-modified bitumen membranes typically are heat-welded or torch-applied. Consumers should be cautioned that NRCA does not recommend torch-applying a modified bitumen membrane sheet directly to a wood deck.
Generally, APP modifiers impart a "plasticized" quality to asphalt, and SBS modifiers impart a "rubberized" quality to asphalt. MB membranes and EPDM, a thermoset membrane, often are confused by consumers because of colloquialisms used by roofing contractors. MB and EPDM membranes are sometimes called "rubber roofs."
MB membranes' surfaces include aggregate surfacing, mineral surfacing, metal foil-laminate, and smooth liquid-applied surfacing.
A roof system composed of a built-up roof membrane with two or three plies and a polymer-modified bitumen membrane cap sheet is commonly called a "hybrid" system. NRCA considers this type to be a polymer-modified bitumen membrane system.
PVC & TPO Roofs
Thermoplastic materials are distinguished from thermoset materials because there is no chemical crosslinking. Because of the materials' chemical nature, thermoplastic membranes typically are seamed by heat welding with hot air or solvent welding. These membranes can be repeatedly softened by heating or hardened when cooled.
There are five common subcategories of thermoplastic roof membranes.
- Polyvinyl Chloride (PVC)
- PVC Alloys or Compounded Thermoplastics
- Copolymer Alloy (CPA)
- Ethylene Interpolymer (EIP)
- Nitrile Alloys (NBP)
- Tri-polymer Alloy (TPA)
- Thermoplastic Olefin (TPO)
- Chlorinated Polyethylene (CPE)
The most common thermoplastic roof membranes are PVC and TPO. The following provides general descriptions of these two systems.
Polyvinyl Chloride (PVC)
PVC sheets contain plasticizers, stabilizers, and other additives to impart flexibility and achieve other desired physical properties. PVC sheets are produced by calendaring, spread coating, or extruding and typically are reinforced with polyester or glass-fiber mats or scrim. Some membranes are available with nonwoven fleece backing adhered to the underside of a sheet.
– Sheet widths range from 6 feet to 12 feet wide.
– Sheets are typically 45 mils to 90 mils thick.
– Seams are sealed by heat or chemical welding.
– PVC membranes are produced in numerous colors, though gray and white are the most common.
Thermoplastic Olefin (TPO)
TPO membranes are produced by calendering with lamination, extrusion with lamination, or extrusion-coating techniques. TPO sheets blend polypropylene and ethylene propylene polymers and are usually reinforced with polyester. TPO sheets contain colorants, flame retardants, UV absorbers, and other proprietary substances to achieve desired physical properties.
- Sheet widths range from 6 feet to 12 feet wide
- Sheets are typically 40 mils to 100 mils thick
- Seams are sealed by heat welded with hot air
- TPO membranes commonly are white or black
PVC and TPO roof membranes can be installed fully adhered, mechanically attached, or ballasted. Most PVC and TPO membranes do not receive surfacings.
SPF Coatings
SPF-based roof systems are constructed by mixing and spraying a two-component liquid that forms the base of an adhered roof system. SPF can be installed in various thicknesses to provide slope to drain or meet a specified thermal resistance (R-value). A protective surfacing is then applied to the foam to protect it from the elements. The first component of an SPF-based roof system is rigid, closed cell, spray polyurethane foam insulation. The foam is composed of two components: isocyanate and polyol. Transfer pumps are used to get the components to a proportioning unit that properly meters the two at a one-to-one ratio and heats and pumps them through dual hoses. The components are mixed with the spray gun, which is used to apply them to a substrate.
The second component, the protective surfacing, typically is a spray applied elastomeric coating, though hand and power rollers can be used. The protective surfacing also can be a membrane, such as a fleece-backed thermoset single-ply membrane. The purpose of the surfacing is to provide weatherproofing, protect the foam from UV exposure, provide protection from mechanical damage and assist with the fire-resistant characteristic of the roof system.
The generic types of coatings used on SPF-based roof systems include:
- Acrylic
- Butyl Rubber
- Hypalon™
- Silicone
- Aromatic Polyurethane Elastomer
- Aliphatic Polyurethane Elastomer
- Modified Polyurethane Elastomer
Mineral granules or sand may be broadcast into a coating to provide increased surface durability and aesthetic value.
The chemicals used to produce polyurethane foam compounds are manufactured or blended to perform in various temperature ranges. Manufacturers of spray polyurethane foam-based roof systems offer materials in different reaction profiles. Profile change is created by altering the chemical ingredients, usually with a catalyst, to compensate for ambient temperature changes. Conditions such as wind speed, sunlight, surface moisture, humidity, and substrate temperature can affect the polyurethane foam's reaction.
EPDM Roofing Systems
Thermoset membranes incorporate principal polymers that are chemically cross-linked or vulcanized. Membranes that are vulcanized also may be referred to as "cured." One characteristic of true thermoset polymers is once they are cured, they only can be bonded to similar materials with adhesives.
There are five common subcategories of thermoset roof membranes:
- Ethylene Propylene Diene Monomer (EPDM)
- Chlorosulfonated Polyethylene (CSPE)
- Epichlorohydrin (ECH)
- Neoprene (CR)
- Polyisobutylene (PIB)
The most common thermoset roof membrane is EPDM. EPDM is composed of two compounds, ethylene, and propylene, derived from oil and natural gas. The following are some characteristics of EPDM roof membranes:
- Sheet widths range from 7.5 feet to 50 feet wide.
- Sheets are typically 45 mils and 60 mils thick.
- Seams are sealed using liquid adhesives or specially formulated tape.
- The membranes are commonly black, but white is available.
EPDM roof membranes can be installed fully adhered, mechanically attached (using batten bars), or ballasted. Most EPDM membranes do not receive surfacings.
Consumers often confuse EPDM and polymer-modified bitumen membranes because of colloquialisms used by roofing contractors. Contractors commonly call both of these membranes "rubber" roofs. However, in most cases, when contractors specify rubber roofs, they are referring to EPDM.
Standing Seam Metal Roofing Systems
There is only one category of metal roof systems used in low-slope applications – structural metal panels. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic (water barrier) characteristics. It is important to note that structural metal panel roof systems can also be used for steep slope roof assemblies.
Most structural metal panel roof systems are designed to resist the passage of water at laps and other joints, as a sealant or anti-capillary designs can be used in the seams. Structural metal panel roof systems possess strength characteristics that allow them to span supporting members.
Shingle Roof
Shingles are flat, rectangular pieces of asphalt, composite, or other roofing material; they're applied from the base of the roof upwards and often overlap to provide full coverage. Shingles come in various colors, from classic black to natural earth tones and contemporary reds, blues, and greens. Modern shingle roofing can also be beautifully textured to mimic slate, wood, or tile – making the roof safer and lower maintenance without sacrificing style.
Two of the most popular shingle styles are 3-tab and architectural. Three-tab shingles are designed such that one piece looks like three individual shingles, and they usually lay completely flat against the roofing installation. Architectural shingles are thicker and less uniform than 3-tab shingles to add a more dimensional appearance. While 3-tab shingles are typically more affordable, architectural shingles perform better and last longer. An important consideration for any roof is the weight. Depending on its age or construction, your home may not be able to support certain materials, especially heavy ones like clay tiles or slate. Luckily, asphalt shingles – especially the 3-tab ones—are incredibly light and work with most homes.
Because manufacturers can create shingles in bulk, they are typically cheaper than other roofing materials. Asphalt shingle roofing has a long expected lifetime. Depending on your specific shingles, you can expect your roof to last anywhere from 10 to 30+ years.
Slate Roof
Genuine slate roof shingles are 100-percent natural stones with no additives. Like natural granite counters, slate roofing is quarried directly from the earth. Slate can be identified by the way the light hits it from a certain angle due to the slate tile's high mica content. Some slates can have up to 40 percent mica content. So, not only is it the texture of the stone that creates its unique look – it's that low-level shine.
One reason for slate's superior roof-tiling quality is its cleavage abilities. Because slate is a sedimentary rock, it is formed of many layers, and these layers can cleave or slice off like the individual cards in a deck of cards. Think of a good piece of slate, much like a deck of cards.
Slate shingle roofing requires installers who are experts at working with slate. Because of this, not all areas have companies that can install slate shingle roofing.
