Cambridge Roofing is the topmost part of your house, shielding it from rain, snow, sunlight, and extremes of temperature. It also protects the underlying structures.
The type of roofing material you choose depends on your needs and budget. There are a wide variety of roofing options available. Some are very durable, while others require regular maintenance and repairs.
A roof is an important part of any structure, providing protection from rain, snow, sunlight, wind and extreme temperatures. Whether you’re building a new home or remodeling your existing space, selecting the right roofing materials will affect the look and durability of your roof. There are many different types of roofing materials available, each with its own advantages and disadvantages.
The type of roofing material you choose depends on a number of factors, including the climate where you live and the structural design of your roof. Flat roofs, for example, require special consideration because they are prone to leaks. For this reason, it’s important to use a highly skilled roofing contractor for any flat roofing repair or installation.
Some flat roofs are covered with a single-membrane system, such as EPDM or rubber, while others are built with layers of reinforced membranes and bitumen called built-up roofing. To construct a built-up roof, organic felt, glass-fiber or polyester ply sheeting are installed over an underlayment of asphalt or a polymer coating. Bitumen is then applied to each ply and cold-applied adhesive to form a waterproof membrane.
Wood is a classic roofing material that adds beauty and class to any home, but it’s not as long-lived as some other roofing materials. It can also be difficult to work with in areas that experience a lot of moisture or wildfires. Wood shingles and shakes are usually made from cedar or redwood and come in a variety of styles. Shingles are thin wedge-shaped slabs of wood produced by precise sawing, while shakes are thicker and have a rougher texture.
Before choosing a roofing material, check the manufacturer’s website for recommended contractors. These professionals have undergone additional training and certification to install the specific product you’re interested in. You can also ask your homeowners insurance company for a list of approved contractors.
Roofing materials vary widely in appearance and function, from the natural thatch used by primitive peoples to the shingled roofs of modern homes. Some roofs serve only to provide shelter from the elements; others are designed to add a distinctive look and increase resale value. The selection of material for a building’s roof depends on the climate and the structure that supports it, whether the building is a commercial or residential structure.
Typical roof materials for a house include asphalt shingles, metal, tile, wood and rolled or flat roofing. The latter is often used on low-pitch or flat roofs, and it is easy to install because it comes in large sheets that are simply rolled out on the roof and nailed in place. Another popular type of roof is built-up roofing, or BUR, which consists of layers or plies of felt and reinforcement that are bituminous and are applied hot.
Materials
The main roofing materials used today include shingles, clay tiles, wood, metal and single-membrane systems such as EPDM and PVC. Each has its own advantages and disadvantages, depending on climate and cost. For example, shingles can be aesthetically pleasing and inexpensive but don’t have as long of a lifespan as other roofing materials. Clay tiles, on the other hand, are long-lasting and have high resistance to fire and moisture.
Historically, people chose roofing materials that were readily available in their environment. For example, early primitive homes used woven lattices of sticks and straw or mud to shield themselves from rain and sunlight. In relatively dry climates, wood shingle roofs can last up to 60 years.
Modern shingles come in many colors, styles and textures to complement any home’s architectural design. They are also available with varying insulation levels and can help reduce energy costs. Some shingles are coated with reflective chemicals that can assist in mitigating the “heat island effect” of urban centers and reducing cooling costs in hot-weather areas.
Slate is a natural, durable material that has long been a favorite for its aesthetic beauty and longevity. Slate roofs can last upwards of 100 years and are highly resistant to fire, moisture and wind. It’s important to note, however, that slate is a very heavy material, and it may require special framing and structural support.
Metal has enjoyed a recent surge in popularity as an alternative to traditional shingles and tile roofs. It’s long-lasting, energy efficient and environmentally friendly. Additionally, it can be made to resemble other roofing materials so that homeowners don’t have to sacrifice their aesthetic preferences.
Single-membrane systems are becoming more common in flat and low-sloped roofing because they are easily repaired or replaced by skilled professionals. Some examples of this type of roofing are EPDM, TPO and PVC. This type of roofing is puncture-resistant, lightweight, and offers excellent UV protection. It is also extremely quiet, easy to maintain and can be installed in different thicknesses. Its durability is also praised, as it has withstood harsh weather conditions like hurricanes and tornadoes.
Installation
Roofing is labor-intensive and dangerous work. Even if you’re not afraid of heights, it’s best to hire a pro. A good roofer should have experience and a clean record. He or she should also have insurance, including workers’ compensation and general liability. Look for a roofer that’s credentialed by the manufacturer of your chosen roofing material. Your homeowners insurance agency may also have a list of approved contractors.
Before beginning work, a roofer should clear away any debris and prepare the area for installation. This process often involves tearing off existing shingles and flashing to expose the roof deck for inspection. Your contractor should also install a waterproof underlayment, such as felt paper or a synthetic rubber membrane. Waterproof valleys are needed where the slopes of the roof meet at a “V” shape. They’re typically made of a thicker underlayment than the rest of the roof, and they’re also nailed down with special roofing nails that have a long, tapered shaft for a better seal.
Shingles are then installed in a staggered pattern across the roof. Close-nail shingle strips should be placed in the first row, with nails spreading out more as you move down the roof. A ridge cap shingle is then installed at the top of each ridge to provide a finished appearance and additional protection against weather elements. Lastly, roof ventilation is added to reduce moisture and regulate temperatures in the attic space. This can be accomplished through gable, ridge, or soffit vents. Venting will also prevent ice dams from forming on the roof.
Maintenance
Regular maintenance procedures help extend the life of a roof, lower repair costs and reduce energy loss. These procedures should include scheduled inspections and prompt repairs, as well as regular cleaning to remove debris, dirt and organic growth. They may also involve applying protective coatings or sealants to enhance weather resistance and durability.
Routine maintenance may also include repairing damaged or worn-out shingles or membranes, patching leaks and replacing missing or damaged flashing. It may also include removing moss or algae growth and cleaning the surface of the roof to prevent discolouration. Other procedures may include removing accumulated debris from drains and gutters to prevent clogging and water pooling, as well as trimming tree branches to avoid damage to the roof.
Leaks and other problems should be repaired promptly to avoid deterioration of interior structures and furnishings. Water-damaged ceilings and walls are unsightly, can cause health and safety issues and lead to costly repairs. Leaks and other damage to the roof can also affect building insulation and energy efficiency, resulting in higher utility bills.
An inspection should check for any ponding water, which can cause damage and odors, and should be dealt with immediately to prevent rot and structural damage to the roof deck and underlying materials. It should also check for blocked drainage lines to ensure that water drains quickly, particularly in flat-roof buildings. Other routine maintenance procedures include examining the condition of roof penetrations, such as chimneys, vents and skylights, for signs of deterioration or moisture intrusion, and ensuring that flashing and caulking are intact. Lastly, it should examine rooftop equipment supports, such as those for HVAC units and solar panels, for proper sealing and support and to verify that they are not causing structural damage or leaking.
