Whether your roof has seen better days, or you are simply tired of the dated appearance, replacing your roof is a major undertaking. It is costly, it takes time, and it requires the appropriate level of understanding and experience, to ensure it is done right.

Sure, you can replace one shingle or two yourself. You might even have the knowledge to lay down tar and patch an area of the roof which is damaged. But, for entire roof replacement, hiring a licensed and bonded contractor, is a far superior option for you to consider. It will cost more, but it is well worth the investment in the long run.

What the job entails

First off, removing the tar, debris, and removing all tiles and shingles from your current roof, has to be undertaken. This requires the proper tools and should be done by a roofing contractor. They have the right equipment, knowledge, and are experienced at this type of service, so they will do it in less time than you would be able to do yourself.

Once removed, the roof should be leveled. Depending on the new roof materials chosen, tar might be laid out. On other surfaces, other bonding/sealing agents are used, for more energy efficient roofs. Only a roofing contractor can determine the appropriate method to seal, bond, and properly level the roof, prior to installing the new roofing material of choice in the home.

The roofers will initially measure the roof, once the old roof is removed. At this point, they will discuss roofing materials, costs, and the types of materials/sealers to be used, in laying down and bonding the roof to the home.

The cost can greatly range. Something like a flat roof might cost £3000. New energy-efficient roof materials, on sloped, or hanging roofs, might cost more than £7000 in certain cases. Many new roof materials can cost onward of £10,000 or more. These materials typically last 30 years or longer, and many have a lifetime guarantee. All of these costs and replacement options will be discussed with the contractor you hire for installation.

Determining whether it is a small patch, or whole-roof replacement job is necessary, are among the different things you will discuss with your roofing contractor. A small leak might simply require a few shingles or tiles to be replaced. If, however, the damage is deeper, and can’t be seen by the naked eye, these jobs typically require a whole-roof installation to be performed.

Regardless of the size of the job, considering all options, costs, and understanding the implications (of repair vs replacement), should be discussed with your contractor.

Additional Projects

At this point, new siding, guttering, or even pressure washing the home, maybe a few services you consider. Most companies offer these packaged-services, so it will cost less money if you perform all services at once.

Even jobs like painting the home, or additions to the roof/home (such as a chimney), are projects which you can discuss with your contractor. Your budget, the duration of the project, and what you plan on doing with the home (resale value, maintaining it, renting, etc.), are factors you should consider, in determining what additional services to complete, when you are replacing the roof.

Cost and Duration

Obviously replacing an entire roof, will take weeks, while replacing a few patches or shingles, might only take a couple of hours. Further, energy-efficient roofing materials are costly but come with guarantees for 20 years plus. Cement, clay, aluminum, and even wood-based roofing materials are available to homeowners.

Each of these materials will have a different cost. The cost of installation will vary depending on the difficulty to install, duration, and how large the roof is. If repair is required prior to installation, this will also increase cost.

As a homeowner, for a simple repair, you can budget a minimum of £500, and a basic replacement can run a minimum of £3000. If there are complex repairs, replacement, or you plan on installing costly, efficient roofing materials, you should budget a minimum of £5000, when you plan on replacing the roof you currently have in the home.

There are a number of reasons you might choose to replace the roof. Whether it is old age, damage, or you are simply tired of the current roof, you should consider costs, duration, and of course, the guarantees a roofer provides to you, so that you choose the best professional to remove the old, and install the new roof you have chosen for your home.
