The Basics of Roofing Installation

Roofing installation is not something that homeowners are often equipped to handle on their own. Some projects are a good fit for DIY, but roofing is not one of them.


Choose a contractor with roofing experience and manufacturer certifications for the type of roofing you choose. Also, ask for referrals and check the contractor’s licenses, insurance, and reputation. Visit for more information.

The cost of roofing installation depends on several factors, including the type and size of roof and the material chosen. It is also important to consider the geographic location and cost of living, as these can affect the price of materials. Another factor is the complexity of the job, which can increase the overall cost. For example, a complicated roof with multiple angles may require more labor and time than a simpler roof.

Whether you’re replacing an old, damaged roof or building from the ground up, there are many options available to you. A new roof requires constructing the structural framework and installing roof decking or sheathing. Then comes the roofing itself, which can be done with shingles, metal or other materials. A roof can be finished with a variety of different shingles, coatings, flashing, vents and other accessories. Adding a solar panel or other renewable energy source can also raise the price of the roof.

When choosing a roofing contractor, ask for references and look at their previous work. It’s best to avoid contractors who won’t provide you with pictures of previous jobs or customer testimonials. Also, check if they’re licensed and insured. Licensed contractors are required to have worker’s compensation and liability insurance, which will cover the cost of medical expenses for workers who get injured during the job.

Reroofing is a great option for those looking to save money and minimize disruption to their home or business. Unlike a full replacement, re-roofing uses most of the existing layers of the roof. It’s more expensive per square foot than a new roof, but it’s still much cheaper than a total replacement.

While a roof is being repaired, it’s crucial that homeowners protect the inside of their home from rain and debris. If a roof isn’t properly protected, it can lead to mold and mildew, water damage, leaks and even electrical problems.


The roofing material that you choose for your home is an important consideration, as it will determine the durability and energy efficiency of your roof. There are a number of different materials to choose from, including asphalt shingles, metal, EPDM membranes, wood and clay. A professional roofer will help you select a roofing material that is appropriate for your home.

A good roofing system consists of a base layer of sheathing, a weather barrier and a roof covering. The sheathing is typically made of plywood or OSB, and it provides a stable surface for the other layers to be attached to. Some roofs may require a specialized sheathing that is resistant to chemicals, mold, algae and pests. A vapor retarder is also recommended to help protect against condensation.

The type of roof covering you select will depend on a number of factors, such as the climate and style of your home. Asphalt shingles are popular for residential use because they are affordable and durable. They are available in a variety of colors and styles, and can be customized to match your home’s design. Other types of roofing include metal, clay tiles and slate.

A quality roof should also be able to withstand high winds and other environmental conditions. Choosing a durable, weather-resistant roofing material will reduce your maintenance costs and increase the resale value of your home.

In addition to traditional roofing materials, roofers are also experimenting with new eco-friendly options such as solar shingles. These shingles convert sunlight into electricity and can add to the resale value of your house.

Another popular option is PVC, or polyvinyl chloride, membranes. They are durable and resistant to degradation from certain chemicals, ozone and ultraviolet radiation. These membranes can be loose laid, mechanically fastened or fully adhered to either nailable or nonnailable decks.


The roofing installation process is a complex task that requires specialized knowledge and skills. It involves putting up a new roof or replacing an existing one. It is typically done by professional roofing contractors who have the necessary tools and equipment to complete the job effectively. During the installation process, the contractor will start by assessing the condition of the roof deck and repairing any damage if necessary. He will then determine the best roofing materials for your project and discuss their strengths and weaknesses. You may choose from a wide range of roofing materials, including shingles, wood shakes, metal sheeting, clay tiles, and slate.

The next step in the roofing installation process is to lay down an underlay support tray. This is a waterproof material that protects the roof from leaks. It is placed over the bargeboard and is interlocked with the next tray. Once the underlay is in place, the contractor will begin to install shingles or other roofing materials. He will start at the bottom of the roof and work his way up to the ridge. He will overlap the shingles by six inches and secure them with cap nails, which are spaced closer together near the edge of the roof and spread out more towards the middle.

The roofer will also install flashing and sheathing around chimneys, wood stove pipes, vents, along hip roofs, and in other leak-prone areas of the roof. Lastly, the contractor will apply a large bead of roofing cement to seal the shingle seams.


The roofing installation process can be complicated, so it is best to leave the maintenance procedures to professionals. It is important to maintain a regular schedule of inspections and repairs to ensure that problems are detected early and repaired before they become serious. A roofing contractor can help develop a maintenance schedule for your home or business that includes the necessary procedures for your specific roof type. This can prevent the need for major repairs and reduce your energy costs by ensuring that the roof is properly insulated.

Roofs need to be cleaned from time to time, depending on the environment and how much precipitation it receives. Cleaning materials such as bleach, soap, and water can be used to remove dirt and debris from the surface of a roof. However, it is important to use caution when using these products, as they can etch the surface of the roof and cause premature wear. Some roofs may require the use of more abrasive materials such as steel brushes, scrapers, and wire ropes.

It is also a good idea to prune overhanging tree branches from the roof. These branches can fall and damage the roof or cause debris to collect on the roof. In addition, they can block sunlight and promote uneven fading of the shingles. The removal of these branches is an important part of the maintenance procedure, and it should be done at least once a year.

The flashing on a roof is another important component of the roof that needs to be maintained. It is usually made of aluminum or galvanized steel, and it is installed over the joints in the roof to prevent water seepage. The flashing on a roof should be checked regularly for damage and to make sure it is sealed properly.

A roof should be inspected after every severe weather event to determine whether it has sustained any damage. Taking the time to check the roof after a storm can save you from costly repairs down the road. A roof should also be inspected for leaks, ice dams, and condensation issues.
