How to Complete a Successful Roofing Installation

When installing a new roof or replacing an existing one, follow the manufacturer’s guidelines. These are based on research, experience, and thought, protecting you from bad workmanship and shortening your home’s lifespan.


To begin, roofers lay an ice and water barrier (if necessary). Then, they run underlayment over it, along sidewalls, rakes, hips, and ridges. Click Here to learn more.

A roof protects your home from moisture, heat and cold, so it is an important part of any building. Depending on your home style and local weather conditions, you may need to choose from a variety of roofing materials. Some materials are more durable and cost-effective than others, so it is important to assess your needs before selecting a new roof. Choosing the right roofing materials will increase the lifespan of your roof and improve your home’s value.

A good roof starts with a sturdy foundation, known as the sheathing. This wood structure is the base that contractors attach shingles and other roof coverings to. The sheathing is typically made from plywood or OSB. It should be watertight to prevent leaking and mold growth.

Once the sheathing is in place, the roof deck is covered with a layer of underlayment. This material is designed to prevent leaking and help the new roof last longer. The underlayment is typically made from a thin layer of felt, asphalt or another material that provides waterproof protection.

After installing the underlayment, a roofer will add the first row of shingles to the roof. This is called the starter course or strip. It is cut from three-tab shingles and has self-sealing adhesive strips on each end. This starter course is essential to preventing leaks and ice damming, as it fills in the gaps between the shingles.

The next row of shingles is added in a staggered pattern with close and spaced nails. A top-tier roofer will use a nail gun to speed up the process and ensure all edges are properly nailed down. They will also use a caulk gun to apply roofing caulk to any raw edges of the underlayment and shingles.

The shingle layer is the most visible part of the roof and can add to your home’s aesthetics. You can choose from a range of roofing shingle styles, including wood and metal. Wood shingles are sawmilled into thin wedge-shaped slabs for a clean, attractive look. Shakes, which are split to produce a rougher texture, are an alternative for homeowners who want a natural, rugged look.


In order to complete a successful roofing installation, it’s essential that the final roof inspection takes place. This ensures that all the materials used on your home’s roof are of high quality and that the installation meets all the required standards. It also provides the opportunity to address any issues or deviations from your roofing project’s original specifications.

During the inspection, a professional roofer will examine the condition of your roof from both ground level and from a ladder. He’ll look for granule loss, moss or other signs of aging, as well as check the gutters for clogs and other problems. He’ll also look at your roof penetrations, including chimneys, skylights and vent pipes. He’ll make sure they’re completely sealed and watertight to prevent leaks.

Roof flashing, strips of metal or other material that direct water away from areas where walls extend through the roof, is another crucial item he’ll inspect. Building codes are strict about the flashing, and it plays a key role in protecting your home from leaks. He’ll look for rust or cracks in the flashing, as well as make sure it’s properly installed and that it follows the roof pitch.

He’ll also examine the fascia and soffit boards, which cover the underside of your roof overhangs, for any rot or other damage. He’ll make sure the soffit boards are properly ventilated to prevent ice damming and to keep pests from entering your home through the attic. He’ll also make sure your roof has drip edge, a strip of edging that keeps water from seeping under the fascia boards and damaging them.

A roof is a complex structure, and it’s easy to overlook even minor problems. However, ignoring these problems can lead to serious consequences down the road. That’s why it’s important to schedule regular roof inspections with your roofing contractor. He can identify small problems before they become bigger and more costly repairs. He can also advise you on what steps to take if your new roof fails an inspection, such as making the necessary corrections. In most cases, a good roofing contractor will work with you to get your roof back into shape so it can pass the inspection.


Re-roofing is hard work and requires some pretty intense physical activity. It is best to leave this job to the professionals unless you are very fit and not afraid of heights. Your contractor will make sure the job site is safe and that you have access to your garage or driveway during the process.

After removing your old roof, your contractor will then install new roof sheathing, decking and underlayment. He will also install drip edge flashing and valley flashing to prevent water intrusion into the home. He will also install ice and water shield along the eaves and in certain other leak-prone areas.

Next, he will install your preferred roofing material. You can select from a variety of shingles including dimensional shingles for a nice curb appeal, three-tab shingles for a more economical option or wood shakes for a natural look and extreme durability. You can also add hip and ridge vents to allow for proper attic ventilation which helps to reduce energy costs by regulating the temperature in your home. These vents come in a variety of colors and styles, including ridge vents, gable vents and soffit vents.
