There is a wide variety of roofing materials available to homeowners today. From standard asphalt shingles to modern metal panels, different choices offer unique styles and colors that can revitalize or enhance the existing architecture of a home. Choosing the right material for a roof is important, as it will have an impact on the cost, longevity and aesthetic of the finished product.
The most popular and widespread roofing material is asphalt shingles, which are made from fiberglass or organic mat that has been doused in asphalt and covered with ceramic granules. They are cheap to install, easy to maintain and offer decent protection against harsh weather conditions. However, they are not a good choice for flat roofs and may not provide as strong an insulating effect.
Wooden shingles and shakes are another traditional roofing option that can be very attractive on homes with a classic or rustic style. However, they are expensive and not as durable as other roofing materials, making them a poor choice in areas with heavy rainfall or wildfire risk.
Concrete tiles are a heavier roofing material that can add a dramatic appearance to the exterior of a home. They are also more expensive than clay tiles and require routine maintenance, but they can last 50 or more years.
For flat or low-sloped roofs, single-membrane systems like EPDM and rubber roofing, thermo-polyolefin (TPO) roofing or PVC roofing are commonly used. These are typically designed to withstand harsh rainstorms and hail, but they may not be as effective in insulating a house or providing resistance against cold temperatures.
Roofing is a physically demanding job, and it can be dangerous to perform without the proper training and safety equipment. Falls from heights and injuries from tools are common, and these accidents can be serious. Roofing can also be a stressful job, and it can lead to health problems such as back pains and stress disorders. As a result, it is not suitable for anyone with physical or mental limitations. If you are thinking of becoming a roofer, make sure to talk to your physician about the risks and benefits.
Installation
Once the roofing crew has access to your roof, they’ll set up protective measures. Tarps will be placed over any plants or anything else below your roof to keep debris from falling and damaging your property. They’ll also cover your attic, pool (if applicable), and move vehicles to paved surfaces to avoid any damage.
Your roof’s skeleton is made of wooden boards called the roof deck, which may be plywood or OSB depending on your home’s construction type. The underlayment is installed on top of this sheathing material and nailed down with close nails at the edges and more spread out towards the middle.
The installation process goes beyond laying new shingles; it’s about clearing away installation waste and leaving your property looking like it was before the roofing project began.
Durability
Durability is a key feature to consider in roofing materials. A roof must be able to withstand heat, cold, wind and moisture. Some of the most durable roofing materials include slate, clay and concrete tiles, and EPDM. These synthetic products can withstand weather conditions and last for 25 to 30 years or more, depending on the type of roofing.
Slate tiles are a beautiful option that add to the aesthetic of a home while being one of the most durable roofing materials. They are rated for class A fire resistance and can stand up to harsh temperatures. Clay and concrete tiles can also withstand severe weather conditions, and they come in several styles including Mission and Spanish-style round-topped tiles as well as flat styles that create French or English looks. However, these are heavy roofs that require additional framing and support and should only be installed on homes that have the structural integrity to support them.
Maintenance
The skeleton of your roof is made up of rafters or trusses, which are then covered by sheathing material known as the roof deck. This may be plywood, OSB, or step sheathing. Roofing underlayment is installed directly over this sheathing and offers an extra barrier to prevent moisture intrusion between the rafters or trusses and the shingles.
Roofing maintenance includes inspection of the roof surface and adjacent areas for physical damage and environmental deterioration. It is usually incorporated into routine building preventive maintenance programs. Housekeeping surveys can typically be assigned to mechanics who perform daily building maintenance activities, while specialized or extensive repairs and those covered by a warranty are usually contracted out to qualified roofing professionals.
The roof surface should be regularly inspected for accumulated debris that can restrict drainage and accelerate membrane deterioration. Debris should be removed promptly to maintain the integrity of the membrane. Drains, scuppers and gutters should be unobstructed and free of debris, especially ice and snow. In the event that a drain, scupper or gutter is blocked by ice or snow, extreme caution must be used when using a scraper to avoid damaging the membrane. If the use of de-icing salt is necessary, it should be closely monitored to minimize its impact on metal drain lines and the membrane.
Underlayment
Roofing underlayment protects your roof from water and moisture by providing a barrier between the roof deck and the primary roofing material. It is also designed to prevent wind and weather from damaging your roof. The type of underlayment you choose will depend on the climate where you live and the roof-covering materials you select.
Generally speaking, most underlayments are a thin sheet of black asphalt-saturated felt paper or rubberized asphalt. Felt underlayment is the most common choice and offers affordable pricing for most projects. However, it is not fully waterproof and requires the primary roofing material to be installed immediately. Additionally, the vapor permeance of felt underlayment can change with humidity and is not very durable.
Synthetic underlayment is made of materials such as polypropylene polymers or polyethylene and is more durable than felt paper. It has the advantage of lasting much longer than felt underlayment, which can wrinkle when exposed to sunlight or moisture during an installation. Additionally, synthetic underlayment is very lightweight. This reduces the stress on the roof and makes it easier for contractors to handle and haul up onto the roof.
Many roofers use both types of underlayment, depending on the needs of a specific project. Felt underlayment is typically used on low-slope and flat roofs, while rubber underlayment is often used on steep-slope roofs (4:12 and higher). In addition, different types of roof-covering materials have specific underlayment requirements.
For instance, some metal roofing materials require a thicker underlayment than wood shakes or other shingle products. Regardless of which underlayment you choose, it is important to follow the manufacturer’s installation instructions carefully to ensure optimum performance. The underlayment acts as the first line of defense against bad weather conditions and roof damage, and it is also critical in preventing ice dams and water leaks. When properly installed, underlayment will provide years of protection for your roof and building structure. For this reason, it is a good idea to replace your underlayment every time you replace the primary roofing materials. Having the right underlayment will protect your entire roof system and save you money in the long run.
