Insulation is an essential part of a roofing installation and can increase the effectiveness and comfort of your home. It prevents heat from escaping the house in the summer and trapping warmth in during the winter, which can save you a significant amount of money on energy bills. It also helps reduce condensation that can damage shingles, causing them to lose their luster and potentially contributing to mold growth.

Insulation comes in various types, each with their own specific benefits, R-values and ideal placements. For example, foam boards are firm structures that help reduce the transfer of heat through structural elements like wood and wall studs, and they can be used almost anywhere in the house. These rigid panels are commonly made from polystyrene, polyisocyanurate or polyurethane. Foam board insulation can be installed in exterior walls, basements and special applications, such as attic hatches.

Rolled fiberglass is a popular choice for new construction. It’s inexpensive and comes in batts that can be easily installed between wall studs and joists. It is not as effective in preventing the transfer of heat between surfaces, however, and its R-value is lower than that of other types of insulation.

Other types of insulation include cellulose, fiberglass and mineral (rock or slag) wool, which are often blown in by experienced installers skilled at achieving the right density and R-value. Cellulose is one of the most environmentally friendly insulation options available, and it can be used in enclosed existing walls or open new wall cavities.

Spray foam is an excellent option for filling small gaps and cracks around doors, windows, vents and other areas. It sets quickly and can be trimmed or painted. It’s particularly good for sealing air leaks in an attic or other unfinished rooms of your home, and it can be applied with special equipment that’s similar to a paint sprayer.


Shingles are flat pieces of building material that cover roofs and protect homes. They are often made from different materials, including wood, asphalt, clay or slate. They are typically laid in courses, with each shingle being offset from the next shingle and covered with a piece of tar or other waterproof material that keeps rain out.

Roof shingles are available in many shapes, sizes and colors to complement any home. They are also available with a range of features that enhance durability, performance and aesthetics. For example, cedar shingles give a rustic look to a house while enhancing its energy efficiency. Architectural shingles, or dimensional shingles, are thicker than three-tab shingles and provide more visual interest. They are available with a variety of styles and shapes, including curved edges that mimic the appearance of shake or tile shingles.

Prior to installing shingles, it is important to cover the entire roof with a layer of roofing felt paper. Standard 30-pound felt paper works well for this step. A roofer should follow the manufacturer’s recommendations for application. For example, the underlayment may need to be staggered if a single strip isn’t long enough for a whole roof section.

Starter strips are typically installed at the eave and rake edges of the roof. IKO’s starter strip has a built-in sealant to reduce the risk of wind uplift and blow-off. This feature, combined with drip edge and an ice and water membrane, can significantly improve your roof’s resistance to storm damage.

When calculating the number of bundles of shingles needed, it is helpful to think in terms of linear coverage rather than area. This way, you can ensure that your shingles will cover the required area of your roof with a small surplus on both the eave and rake sides of the roof.


A crucial part of the roofing system that protects your home from the elements, underlayment is a layer of protection between the roof deck and the shingles. It serves as the secondary line of defense against rain, sleet, snow, wind, and debris. It helps ensure a waterproof seal and prevents moisture buildup within the roof structure, which can lead to rot, mold, and mildew.

Generally, underlayment is made of either asphalt-saturated felt or non-bitumen synthetic materials. It’s important to choose the right underlayment for your home, as different types are suitable for a wide range of weather conditions. Ultimately, your roofing contractor will determine the best type of underlayment for your project based on local building codes and your preferred roofing materials.

Underlayment provides a barrier against water infiltration while the roofing material is being installed. It also keeps the roof deck protected from physical damage caused by heavy equipment, debris, or other factors. This can help extend the lifespan of your roof system.

The underlayment layer may be self-adhering or a traditional woven felt material. Self-adhered underlayments have a sticky back that adheres to the roof deck and forms a waterproof seal. These underlayments are primarily used in leak-prone areas such as eaves, valleys, vents, skylights, chimneys, and the top of the roof. They also offer a non-skid surface to make it safer for roofers to walk on.

Felt underlayment is traditionally made from organic mat or paper that’s saturated with asphalt to aid in water resistance. It’s an affordable option, but it rips easily and can absorb and wrinkle when wet. Choosing the right underlayment for your home is important, as it will determine how long it will last and its ability to perform in various climates.


Flashing is a thin strip of metal that professionals install around areas like chimneys, vents and skylights. It helps direct water away from those critical parts of the roof to prevent leaks. It also seals and protects the joints between the roof plane and other features that protrude through or up against it, such as walls.

There are many types of flashing, each designed for a specific application. Generally, it is made of galvanized steel and bent into shape to fit in a particular joint. For example, step flashing looks like a small rectangular piece of metal with an open end that fits over the top of a pipe or vent. The open end may be made of either a metal tab that slides into place over the pipe or a rubber compression fitting that will wrap over PVC or other pipes. The base flashing that lays on the shingles and counter flashing that rests against the penetration are also part of the flashing system to provide extra protection against leaks.

Other types of flashing include continuous flashing, which is a long strip that covers a larger joint such as where the roof meets a wall of your house. Often, this type of flashing has expansion joints built into it to allow it to bend and move with your home as it expands and contracts in different weather conditions.

Other important pieces of flashing are gutter flashing, which is a long strip of painted metal that goes over the tar paper or ice and water shield before the shingles are installed; and kickout flashing, which looks a little like an L-shaped scoop that extends out from the end of your step or continuous flashing and helps guide the water to where it meets the gutter. This can help prevent the water from running down your fascia boards and causing foundation problems.


Gutters are troughs along the eaves of your roof that carry rainwater away from your house. This keeps it from seeping through the shingles or damaging your foundation and walls, while adding to the beauty of your home’s exterior.

Without gutters, water pools on the roof and can cause rot, mold, and even leak into your living space. Gutters and downspouts help to prevent this by carrying water away from the house and into a storm drain or downspout.

A quality roofing installation will include the installation of gutters. You can find a wide variety of gutters in a range of materials and styles, so you’ll be able to choose the ones that best match your budget and aesthetic preferences.

One popular option is the seamless gutter system, which has no seams or joints and is made from aluminum, copper, zinc, or steel. It is more expensive than other types of gutters, but it is less likely to leak or overflow and offers a more attractive appearance.

Most homeowners have their gutters installed by professionals, but if you’re handy with basic tools and don’t mind heights, you can do the job yourself. Straight sections of vinyl or aluminum sold at home centers and online are well within the grasp of most DIYers, although a pro may be a better choice if your house is taller than one story or you want custom gutters that are made on site.

No matter what type of gutters you choose, it’s important to maintain them regularly. Cleaning them will keep them from becoming clogged with debris, such as pine needles, which can cause serious damage to your roof and gutters over time.
