Research has shown that GRP doesnt really deteriorate in fact, it has remained in the same condition throughout the testing periods that have been trialed. Some experts would even argue that GRP products applied by a specialist company could potentially last a lifetime.

A residential flat roof is basically a horizontal base fixed to the buildings ceiling joists and then covered with a waterproof membrane. To enable rainwater to drain from the roof, a flat roof is slightly pitched by just a couple of degrees.

Flat roofing is both economical and efficient, which saves the owner energy and money. Its construction involves considerably less labor and materials than its pitched roof counterpart and full replacement can often take just a day

Where Should You Install A Flat Roof

This can save you hundreds of dollars in heating and cooling costs. For maximum savings, you need to make sure that you are installing rigid foam insulation with a proper R-value.

Installing The New Roof

The final stage is the installation proper. Depending on the material, this can go in different ways. For instance, with felt, the material is laid in place and secured with nails or drills. Meanwhile, with rubber, the best means of securing the material is with a strong adhesive.

A similar technique is required when repairs are necessary, but simply on a smaller scale. So, once the damaged section is inspected and removed, the last steps are to measure it and replace the old material with the new one.

However, replacing one section of the roof without touching the other areas could lead to its own problems. So, if there is a problem with the roof, or some damage occurs, unless the effect is minuscule, the standard recommendation is to replace the entire roof.

Flat Roof Drip Edge Repair Cost

Repairing flat roof drip edges ranges from $150 to $400. Drip edges are L-shaped metal pieces positioned at the edge of the roof.

Metal drip edges are strong, but they become dented or damaged in storms or because of falling debris. So, they may occasionally require patching or cleaning.

Diy Roof Replacement Vs Hiring A Roofer

For homeowners looking at replacing their roof instead of hiring a professional, an asphalt roof will cost $3,000 less to $6,000 less . However, while small roof repairs are cheap and relatively easy to carry out by the homeowner, as long as safety precautions are taken, roofing a home is better done by professional roofers. The downsides of completing the work as a DIY project are:

  • In removing the original roof, you may cause issues that will lead to leaks.
  • Once the old roof is off, you could miss structural issues or things that will contribute to more leaks.
  • You might not create a perfect weather seal to protect your home from the rain when installing the new roof.
  • You could introduce issues that translate to increased utility costs from heating or cooling.
  • You could fall from your roof.
  • You could negatively impact the resale value of your home.

Your roof is the single biggest surface barrier between you and the elements. Given the importance of the roof, and the potential for significant problems, we suggest looking for bids from the roofing professionals we have on HomeGuide before making a final decision to do the work yourself.

What Types Of Flat Roofs Are There

How Much Does Replacing a Flat Roof Cost?

Any material used to construct a flat roof must be watertight because even though flat roofs are built on a slight incline, they are still very susceptible to leaks. That said, there are five main types of flat roofs: roll asphalt, single-ply, multiple-ply, modified ply, modified bitumen, and flat-seamed metal.

  • Roll asphalt flat roof
  • Roll asphalt comprises layers of asphalt-coated fiberglass, tar, felt, and water-resistant materials, all of which are kept in place with nails or asphalt cement. The top layer is covered with gravel, which protects the roof from ultraviolet rays. This type of flat roof has been used for over 100 years and is generally the cheapest however, it doesnt usually last much longer than 10 years.

  • Single-ply flat roof
  • Single-ply flat roofs are made from one layer of materials that are a bit like rubber. These materials cost less but are studied and more energy-efficient than roll asphalt roofs. Usually, single-ply roofs are made from EPDM, uPVC, ethylene, and TPO. These are all mold-resistant and low-maintenance. Single-ply roofs usually last for up to 12 years.

  • Multi-ply flat roof
  • This type of flat roof comprises lots of layers of fiberglass, which is packed between layers of asphalt. The big benefit of multi-ply flat roofs is that they are reinforced, lasting longer, and are less damaged. They can last as long as 30 years.

  • Modified Bitumen flat roof
  • Flat-seamed metal flat roof

    How Do Flat Roofs Drain

    How Much Does it Cost to Replace a Roof?

    Its no secret that flat roofs are more resistant to severe weather conditions compared to other roofing systems. But when it rains or snows, where does it go once it all falls? Flat roofs are not able to use their slope or the power of gravity to remove water as efficiently compared to a shingled roof. They need a specifically designed drainage system to get the job done. Lets take a look at the two most commonly used flat roof drainage systems:

    • Interior Drain An interior flat roof drainage system is commonly found on larger commercial flat roofing systems, but can be used for your residence as well. With the slight slope of a flat roof, water will flow similar to how sump pumps and drain tiles are designed. The water will flow into the drain into an internal series of pipes which are located beneath the roof. Then the water is carried out and pumped out and away from the foundation of your home or commercial building.
    • Scuppers This flat roofing drainage design is simply just large square gaps located in the curbs or walls along the buildings roofline. Scuppers allow water to flow throughout the sides of the building. It is common to install downspouts directly below the opening to catch and divert the water away from the foundation of the building.

    Ensuring The Professional Is The Right Fit

    Use the below questions to make sure the professional youre hoping to hire is the right fit for you.

    • What experience do you have? Its always useful to know if they are a well-established company or they are just starting. You might find that a newer company is slightly cheaper, or you may prefer to pay more for experience.
    • Have you got customer feedback and photographs of any work youve done in the past? The tradesperson may have a portfolio to show you, or they may direct you to their website. Websites often have case studies, photographs, and customer testimonials.
    • Are you a member of any trade associations? Trade associations will only grant membership to tradespeople with a good work record. They must also have high standards of workmanship.
    • Do you have insurance? Is your public liability insurance up to date? Public liability insurance is vital for all tradespeople as it protects them and you from any injury or damage claims should an accident occur during the installation of your felt roof.

    What Is A Flat Roof

    Many homes and commercial buildings across the United Kingdom have a common feature a flat roof.

    People often think of flat roofs as being completely flat, however they do have a very slight pitch to enable rainwater to drain away efficiently. The last thing anyone wants are water pools on the flat roof surface leading to the steady breakdown and decay of the material itself.

    Flat roofs are typically found on extensions, garages, dormers, balconies, carports and outbuildings. They can be very cost effective and slightly more flexible than a traditional pitched roofing system.

    Many of our customers are led to believe that flat roofs are not as durable as slate and tiles but we feel differently.

    If the correct material, system and roofing contractor is chosen, with the appropriate approvals such as Bauder, then a flat roof can last in excess of 25 years.

    Combining this lifetime vs the cost and you can see a flat roofing system will often be a great choice for certain types of building and use cases. If you are unsure as to whether or not you should choose a flat roof or pitched roof, then please feel welcome to contact SPS Roofing Ltd for advice and flat roof estimates.

    So now weve covered exactly what a flat roof is and where they are typically found, lets explore the benefits

    Cost To Redo A Roof With A Different Type

    If you are replacing your existing asphalt roof with a roof type that is heavier, like slate or stone tiles, the potential exists where you may need some structural reinforcement for the rafters and joists in the roof framing structure to support the additional weight. The reinforcement alone will average between $500 and $1,500 depending on the size of the home and the amount of reinforcement needed. Add the cost for your chosen roofing material plus labor on top of that.

    Roof Tile Replacement Cost
