Types of Roofing Tiles
Clay and Concrete Tiles
Clay and concrete tiles are traditionally one of the most popular roofing materials. They are made from fired clay or concrete mixed with other raw materials that give the tiles their color and texture. Clay tiles tend to be thicker and heavier than concrete tiles. Some advantages of clay and concrete tiles include:
– Durability – When installed and maintained properly, clay and concrete tile roofs can last 50-100 years. Their dense material makes them highly resistant to damage from weathering, hail, and other environmental factors.
-Fire resistance – The non-combustible materials used to make clay and concrete tiles means they have excellent fire resistance properties. They do not burn or emit toxic fumes if exposed to flame or heat.
-Aesthetics – The natural variations in color and texture give clay and concrete tile roofs an attractive, authentic look that enhances any architectural style. A wide variety of profiles, shapes, and colors are available.
-Energy efficiency – The mass and low absorptivity of clay and concrete tiles allows them to maintain cool interior temperatures during hot weather. They also have superior insulative properties which translate to energy savings year-round.
Potential drawbacks of clay and concrete tiles include their weight, which makes them expensive to transport and install, as well as their brittle nature which can lead to cracking or breakage if not properly handled. Their high upfront material and installation costs also make clay and concrete tiles a more expensive option compared to other roofing materials. Proper installation is critical to prevent leaks or premature failures.
Concrete and Clay Tile Installation
Installing clay or concrete tiles involves several key steps:
-Underlayment – The roof deck is covered with an underlayment like felt paper or synthetic mats to add an extra moisture barrier before installing tiles.
-Starter strips – Starter strips are fastened along the bottom edge of the roof to provide the first row of tiles something to lock onto.
-Tile installation – Tiles are installed either using a low-profile mortar bed or by fastening them to the roof with nails or screws through pre-drilled holes depending on the tile design. Proper overlapping is important to prevent leaks.
-Hips and ridges – Special hip and ridge tiles are installed to finish off the roof edges and changes in plane. They are designed to integrate seamlessly with the main field tiles.
-Flashing – All penetrating elements like vents, plumbing stacks, and chimneys require lead or zinc flashing to direct water away from vulnerable areas.
-Inspection – The completed installation is inspected to ensure proper sealing and attachments before being signed-off.
Installing clay or concrete Roofing Tiles demands attention to detail and following the manufacturer’s instructions closely. An experienced professional roofer is highly recommended for the job. Improperly installed tiles can be at risk of blowing off during high winds or failing prematurely due to leaks.
Metal Roofing
Metal roofing such as steel, aluminum, zinc, and copper has many modern applications as a durable roofing material alternative to traditional tiles or shingles. Some key advantages of metal roofing include:
-Lifespan – When properly installed and maintained, metal roofing like steel can remain functional for 50+ years which is significantly longer than asphalt shingles. Products like copper can last well over 100 years with routine cleaning and maintenance.
-Fire resistance – Non-combustible metal materials provide excellent resistance to fire and reducing risk of wildfires spreading. Many metal roofing products have a Class A fire rating.
-Sustainability – Metal is one of the greenest roofing materials as it is completely recyclable at the end of its long service life. It is also manufactured using recycled content in many cases.
-Hail and wind resistance – Rigid metal panels and standing seams stand up very well to high wind events and hail without taking damage like other brittle materials may.
-Low maintenance – Metal roofs require very little routine maintenance other than periodic washing. Their baked-on finishes mean no recoatings are needed like with wooden shakes.
Potential downsides of metal roofing include higher material and installation costs upfront compared to asphalt or tile options. The weight of certain metal products like stone-coated steel can also require additional engineering of the roof structure in some cases. Noise from rainfall on standing seam metal roofs is also a consideration, though most modern seam profiles minimize this effect.
Metal Roofing Installation
Installing a metal roof starts with preparing the decking as with any roof type. Various metal roofing systems are then installed:
-Shake & tile replica roofs – Made to resemble the look of wood or tile but are interlocking panels installed like shingles. Nailed directly to the decking.
-Standing seam metal – Ribbed or trapezoidal panels that are mechanically seamed together on site. Installed over purlins or battens for ventilation.
-Batten seam metal – Panels with raised seams that are nestled between horizontal battens during installation. Allows for significant spans between supports.
-Flashings – Must be installed at all edges, penetrations, and changes of plane to direct water shed properly and prevent leaks.
-Inspection – Installed metal is thoroughly inspected before sign-off to ensure seams are tight, flashings are lapped correctly, and the roof was installed as specified.
Proper tools and training are needed to cut, measure, and install metal roofing panels to manufactures guidelines. Like tile work, professionals are highly recommended for ensuring water-tight durability.
Properly researching local codes and environmental factors, consulting trusted contractors, and accounting for budget and lifespan needs can help homeowners select the ideal roofing tile or metal option suited to their home and climate. Durable materials offer both performance and aesthetic benefits when installed correctly.
