How Much Is A New Flat Roof

Do Roofers Have Any Hidden Costs

Flat Roof estimate and how we price a new flat roof.

Apart from the usual roof replacement costs mentioned above, there may be other costs involved that you have not thought about, such as:

Gutters & Fascias

When you receive your quote for a new roof, you might want to check if it includes replacing soffit and fascia and new gutters in the price. Usually, the cost of new fascias and gutters would be an add-on and billed separately.

Waste

You will need to hire a skip to remove the waste from your old roof. Most roofing companies will include the cost of skip hire within your quote, but you might want to check it is included for your own peace of mind. You should expect to pay around £200 to hire a skip.

Access

Most reroofing jobs will need scaffolding erected around your property. Have a look through your new roof quote and see if scaffolding has been included within the quote. Hiring scaffolding for an average three bed semi-detached house costs around £1000.

Will A Roofer Replace The Fascia And Soffit During My Roofing Project

You may or may not need the roof framing repaired and strengthened, sheathing replaced, or soffits, facia, flashing, etc. replaced at the same time as your roof. In most cases, it is unlikely that you will need an entirely new roof with everything replaced, but certain parts of your roofing system might need repairs made to prevent leaks after the new roof has been installed.

Flat Roof Installation Cost

Installation is the process of installing a new roof on your residential or commercial property, without having to tear off an old one. Depending on the size and complexity of your home, the cost of labor for installation can start at $5 to $5.50 per square foot and can go up to $7 to $9 per square foot. Keep in mind that it may differ depending on the material and contractor you choose.

Additional Garage Amenities Prices

If you are building a garage for purposes other than housing your car, there may be additional costs related to the amenities you plan to include.

If you want to build a workshop space in your garage, you will need to pay for the materials such as tables and storage space, as well as mounts for various tools.

Additionally, if you are not building it yourself, you will need to contract a carpenter, which generally costs around $75 per hour.

For those living in hot or cold climates, you may decide to install heating or cooling in your garage to make it a usable space, especially if you are including a workshop or something of the sort.

You can purchase an all in one heating and cooling unit for about $1,000. If you are looking for a more elaborate HVAC system that is hooked up to your homes temperature control, the cost will be much higher.

If you require running water in your garage, such as a sink for your workspace or an emergency shower, you will need to hire a plumber.

Depending on the type of fixture and how far away your garage is from the rest of your homes plumbing, a plumber should be able to install a water fixture for $1,000 to $3,000 on average.

If you want to include a fridge or a freezer, for your garage, be sure to include the cost in your budget calculations.

A refrigerator can range between $100 for a mini-fridge and $2,500 for a fully-equipped, high-end fridge and freezer.

Flat Roof Repair Costs

As with tiled roofs, repair costs will vary depending on the nature of the issue – it is possible to patch flat roofs, or take care of problems such as blisters, and this can typically be done for a few hundred pounds. If a number of problems occur though, it can become more cost effective to replace the entire roof, especially as many flat roofs may only have a good working life of between 20 and 30 years.

Cost To Install A Flat Roof

Compared to the cost of asphalt shingles, most contractors charge 20-35% more to install a flat or low slope roof.

This is because its actually difficult to install a flat roof correctly so that it remains leak free. Out of the total installation cost on a new flat roof, around 70% will be the cost of labor!

Flat roof replacement cost starts at $5 5.5 per square foot, but can go up to as much as $7-9 per square foot, depending on roof size and complexity.

This includes tear off, insulation and the new roofing membrane. Final prices depend on the quality of the material, roof size and complexity, your contractor and location.

Installing a flat roof on a two or more storie home costs at least 30% more than on a single storie house.

Moreover, curbs, corners and penetrations, such as chimneys, vents and skylights will all increase the total cost, because they need to be flashed in order to be watertight. This adds more hours of labor, and drives up the final price.

Overall, labor costs are higher because flat roofing is a specialized field that requires expert knowledge, tools, and a particular set of skills.

This means that a regular contractor, who shingles roofs, will NOT be able to properly install a single ply membrane or any other flat roofing material.

In fact, most flat roofs leak due to faulty installation. Even the best, most expensive membranes will fail, if a contractor does not know what he is doing.

Factors That Impact The Price Of Flat Roof

  • Height of the Roof:

    Tall flat-roofed properties tend to be more expensive that shorter houses, because a flat roofer will need to add a chute to bring the old roofing material down to the bottom.

  • Accessibility:

    Generally, houses in Toronto are closer together than houses in Mississauga, so properties that are not as easily accessible for a dump truck to enter may require the need to remove old flat roofing material using wheelbarrows. This will tend to increase the price of your flat roofing quote. In some cases, the roofer may need to consider going from one roof to another to access the flat roof as well.

  • Existing Flat Roof Layers:

    The number of layers on the flat roof has a big impact on the cost of replacing your flat roof. A flat roof with nothing on it will be much cheaper to install new flat roof material vs a flat roof with 8 inches of the old roofing material. And the cost is ever higher in older from the 1920s -1940s where fibrous material were used on flat roofs.

  • Obstacles:

    The numbers of obstacles on the roof has an impact on the cost for replacing your flat roofs. Obstacles can include siding, vents, AC units and posts on decks. For example, if you have a house with a siding and posts all the way around, then before new flat roofing material can be installed, a roof contractor will need to take the siding off, cut the posts out or flash each posts.

Eps And Iso Insulation Boards

We also have flat roof systems with EPS and ISO insulation boards installed under the roof systems.

EPS insulation boards are commonly used for sloping a roof system to the drain and scupper areas, this is a more economical way and available with slopes of 1%, 2%,3%, 4%, or even high.

ISO insulation boards are designed to offer improved thermal resistance a better R value. ISO is a Polyisocyanurate insulation panels available in 4 ft × 4 ft or 4 ft × 8 ft and can vary in thickness depending upon what R value your project is looking to gain.

Both EPS and ISO insulation boards can be used in the other flat roofing or low sloped roofing systems which are shown below.

  • Is the tile type changing? If yes, the roof fixings for the panels will change, so that becomes more costly.
  • Will the PV panel location or layout change? If yes, the number of fixings and rails required increases, so again more costly.
  • Are you re-installing the same number of PV panels? If no, it may be more costly as more or different inverters are required.
  • Is the pitch or orientation of the roof changing? If yes, the performance of the system may be different, so again the inverters may need replacing.
  • In general solar PV panels are relatively flexible, theres a wide variety of solar PV panels and inverters on the market, so removing/re-installing or replacing parts is not complex.

    We recommend speaking to your original solar PV panel installers at the same time as your roofer. The works are heavily linked and will generally follow the schedule PV system electrical isolation, PV system removal, roofing works, and PV system re-installation.

    Please note: Be aware of any warranties/guarantees that may be in place, and speak to your original installer before doing any work. You could potentially void the warranty by not using the original installer for any modification works.
