Often homeowners are ready to purchase a new roof based on design and looks without considering other important factors. Roofs can have flat, low, moderate or steep pitches, which determine suitable roofing materials for the job. For example, many materials are not suitable for flat or low roofs because of the lack of pitch and drainage qualities. While other varieties work better for moderate or steep roofs. You should learn about the pros and cons of the most common roofing materials for family homes before making any decisions.

Roofing Systems

Typical roofing systems range between low sloping roofs to steep roofs. Low sloping roofing materials are generally weatherproof and water impermeable. They are designed to handle slopes of 14 degrees or less. Water shedding materials are used when installing moderate to steep roofs that exceed 14 degrees or more.

Flat Roofs

Tar and gravel roofing, also known as built-up roofs, are traditionally used for flat roofs. These consist of several layers of waterproof materials, which are laid between a layer of river stone and hot tar. Tar and gravel roofs are inexpensive and fire retardant, which might be a good choice for you. However, installation is very messy and smelly, and roofs often require strengthening because of the weight.

Rubber membrane roofs are specifically designed for flat roofs. They are durable and resist sunlight damage. However, these materials absorb significant amounts of heat in warmer climates, which could increase air-conditioning bills.

Low Roofs

Metal roofing is primarily used on low or steep roofing. You’ll enjoy the long-lasting qualities and color choices. These roofs can be made of copper, aluminum or steel. Copper roofs can be left unfinished, and they will eventually turn green patina with aging. Some people may prefer painted finishes that come in numerous colors. Roofs are also available as shingles or sheets. Metal roofing absorbs less heat than other materials like asphalt, and it’s ideal for low to steep roofs.

According to Braun’s Roofing, a company that has been Houston’s roof repair expert since 1987, asphalt shingles are one of the lightest and popular types of roofing materials used on homes. These common shingles are composed of fiberglass, asphalt and contain a mineral granule coating. Unfortunately, asphalt shingles are not environmentally friendly, and they are not as durable as other roofing choices. However, they cost far less than clay, slate and metal roofing systems. They offer fair wind and fire resistance and are most effective on low, moderate and even steep roofs.

Moderate Roofs

Clay tile roofs come in a variety of natural clay colors. However, they are somewhat brittle, but they do last for years with very little maintenance. Clay tiles may require reinforcement framing, and they are perfect on homes with moderate to steep roofs.

According to Braun’s Roofing (www.roofrepairsinhouston.com), plastic polymer shakes can be made to look like slate or wood, and they are much lighter. These are molded from plastic polymer materials, and they last for years. Their low maintenance and lightweight qualities make them an ideal solution for moderately pitched roofs or even those that are very steep.

Concrete tiles are composed of sand and Portland cement. Homeowners may choose from a slate, wood or clay tile appearance. Roofs made from concrete tiles usually require reinforcing. These are long lasting, fire resistant and require very little maintenance. These tiles are best used with moderate to steep pitches.

Wood shingles provide a pleasing appearance, and they work well for moderate to very steep roofs. The shingles are typically constructed of redwood or cedar. However, they have a short lifespan and unless they are treated, they offer poor resistance to fire.

Steep Roofs

Homeowners with very steep roofs should consider a slate rock roof. These natural materials are expensive, but they are fire and wind resistant, in addition to being durable. Slate roofs offer a unique, natural appearance, but most roofs will need reinforcing to handle the weight of the stone.

Besides choosing a roofing material that enhances your home and fits your budget, consider the roofing qualities. Some materials stand up to high winds and fire better than others. Alternatively, you may be in the market for longer lasting materials, low maintenance or an inexpensive roof.
