Whether you are buying a brand-new roof for an existing house or for a space that you are building from scratch, there is an array of readily available materials that are worth your consideration. These comprise wood, asphalt, and composite shapes, along with concrete, clay tiles and slate. Style is important, but it isn’t the only factor. Material weight, product cost, and installation requisites must also influence your choice. The following are the things you should know:
Before we discuss materials, let’s spend some time on terminology. Typically, a roofer does not use the “square feet” measure. They instead talk in squares, which represent a unit of measurement – a square is equal to 100 sq. ft. in area. This is equal to 10 feet by 10 feet square. A typical 2000 square feet, two-story house with gable roofing would comprise about fifteen squares or a roofing area less than 1,500 sq. ft.
A New Roof’s Cost
Multiple things affect a new roof’s cost. The material’s price is where it all starts, but other factors should be considered too. One of them is the existing roof’s condition if a house is being remodelled – if old materials must be stripped off, and the supporting structure requires repair, all of that would cost money. Another contributing factor is the roof’s shape. Gable roofing with zero or few breaks in its planes (such as vent pipes, chimneys, or dormers) would constitute a basic roofing job. A house with intersecting rooflines (the intersection points are called valleys), multiple chimneys, skylights, turrets, or other elements would set you back significantly.
Different roofs may need different roofing materials. A low-sloped roof or a flat roof could demand a surface that’s not the same as the one having a steeper pitch. Tile, slate, and other similar materials are quite heavy, which several homes’ structures may not be able to carry or manage. Look at the following options and discuss them with your designer to arrive at the job estimates.
Asphalt: This material is a very commonly used roofing material because it’s incredibly inexpensive and doesn’t require much skill to install. The roof is made from a fiberglass medium that is infused with asphalt and later provided surfacing that feels and looks like sand granules. There are two primary configurations available: the regular single-thickness variant and laminated, thicker products. The standard variant costs approximately half the price of the laminated variant. However, laminated shingles have a desirable textured look and last much longer (usually more than 25 years, versus more than 15 years). Prices start at around $50 per square. But based on the shingle type chosen and installation, costs could go up considerably.
Choosing a New Roof
Wood: Wood has been historically used for roofs, and the material is still a reliable option. However, in certain regions, fire codes prohibit its usage. Typically made of redwood, southern pine, or cedar, shingles are split or sawn. They could last 25 years on an average, like asphalt shingles, but would usually cost twice the price of asphalt.
Metal: Steel, aluminium, copper-and-asphalt, copper, and lead are durable, but expensive roofing materials. The copper/asphalt and lead varieties are usually installed as shingles. Other metals are usually made for seamed roofs comprising vertical metal lengths that are joined using solder. These roofs begin at around $250 a square but usually cost at least two times that price.
Cement and Tile: Tile roofing’s half cylinders are common on Mission and Spanish Colonial styles; certain metal roofs and cement mimic the wavy effect of tiles. All are quite durable, expensive, and quite heavy.

Slate: Among all roofing materials, slate is the most durable. However, not all slates are made the same – some coming from Vermont quarries, and some from other states such as Pennsylvania. However, the best part is the material would outlast the fasteners holding it in place. In fact, century-old slate is invariably recycled for reinstallation, expecting it to come good for another hundred years. However, slate is expensive – prices typically start at around $800 per square – and quite heavy.
Selecting a Roof Material
Usually, if you’re remodelling, your house’s current roof would determine the roofing material you end up choosing. If you were to look at other options, you should consider not just the cost but also the texture, color, durability, and weight of your alternatives, along with what has been traditionally used on houses such as yours.
Whatever roofing surface you choose, you would probably require flashing. Flashing plays a major part in all exterior jobs, both on the siding and roof. Flashing is plastic or metal film (copper or aluminium – lead, at times). It’s applied in strips onto areas where disparate materials connect, such as the roofing shingles and masonry chimney intersecting, where the siding touches upon window frames. Solid flashing work is imperative to keep a structure watertight since the most likely spot for leakage to show up is where various materials meet.
Whatever roofing materials you choose, the coursing must be parallel to the edges of the roof and even to the eye. Between different courses, the joints must be staggered to mitigate leakage. Steer clear of a contractor that uses tar for joints. Except in case of some roofs that incorporate a membrane, tar is a languid expedient that mustn’t be utilized for a new roof surface.
For most roofs, a material such as building felt (or tar paper) gets rolled on prior to the shingles getting nailed into position. However, with cedar shakes, furring strips’ lengths (sometimes referred to as “cedar breathers”) would be placed across the roof so that the roof could breathe. In snowy places, a membrane known as ice and snow shield could be laid too.
