What are the benefits of re-roofing (retiling)?

A roof is one of the most important components of a house. Given how inclined they are to natural deprecations, maintenance becomes necessary to protect them and make our home feel more secure. Moreover, as roof structures tend to wear out faster, re-roofing or roof restoration is always necessary to protect the property and increase its value.

What is re-roofing?

Re-roofing is basically tearing down the current roof to install an entirely new one.  Generally, re-roofing is done when the damage to the current roof is too severe to be repaired and the cost of repairing it too high. Replacing a roof can be expensive, especially if the roof’s support structure also needs to be replaced.

What is roof restoration?

Roof restoration is preferred in situations where the roof is not damaged beyond repair. Similar to re-roofing, in roof restoration, the roofing structure is not entirely torn down, but it is thoroughly checked for damages which are then repaired to guarantee its safety. Homeowners will need to hire professional roofers to work on the roof to enhance it, repair any damages, and improve the appearance of the rooftop.

After the roof restoration has been completed

After repairing the damage, the next step is to repaint the roof tiles and then coat them with another layer of color, giving the roof a new and fresh look. The goal is to secure the roof, give it a fresh new look, and prevent further damage and degradation.

When should I replace or repair my roof?

Sometimes your roof’s condition might be that bad that persistent leaks cannot be solved by a simple patchwork or tile replacement job. When this is the case, it might be necessary to have your roof replaced as soon as possible to prevent further damages.

Here are some tips to help you determine if you need a new roof:

Roof age: if your roof is older than 20-25 years, your old roof has been removed, and who built the new one only with one layer of shingles.

Shingles are curling: If your shingles look curled and losing granules, this might be a sign that your roof needs replacement.

Roof valleys: If your shingles are falling apart or missing near the roof valleys, this is a clear sign that your roof is susceptible to roof leaks.

Missing shingles: If you notice that after a heavy rainfall or storm, your roof is missing shingles, your roof needs repair.

Chimney flashing: Consider replacing your old cement or tar roof chimney flashing with a new metal flashing system.

Shingle granules in the gutters: if your roof looks darker or inconsistent in some parts, this might be a sign granule warning out.

Daylight through roof boards: This is always a bad sign if you notice any moisture in the insulation or daylight coming through the roof board.

Interior Water Damage: If you notice stains on your interior ceilings or walls, this is a direct indication that either your roofing system is damaged or that the ventilation is not good enough.

Replacing your roof is not an easy job, and it may actually sound daunting, but it is probably the only way to deal with this situation effectively. Roof replacement is not always more expensive than roof repairs because extensive repairs could easily add up to the cost of roof replacement, especially if you are doing constant repairs on an old roof.

How much to reroof a house?

The cost of re-roofing a house will vary depending on several factors, including:

    • the professional roofer you hire,
    • the size of your roof,
    • the quality of the materials you will use and
    • whether or not you are altering the style of your current roof.

Roof repair causes

Nearly all roof leaks are much the same and are a result of similar kinds of problems. Examples of these are:

Blown or missing shingles — Irrespective of the material they’re manufactured from, roof shingles are susceptible to lifting due to high gusts of wind. Lightweight materials are affected by this compared to heavier ones. However, even heavy shingles made of asphalt may peel off and be swept away by the wind, causing your underlayment and roof deck susceptible to the outside weather.

Broken or dripping pipe flashing — The roof’s vent pipes lay below your roofing material. They are generally well sealed. However, deterioration of the pipe flashing or maybe of the sealant could make it easy for water to penetrate right through to the inside.

Step flashing of chimney/skylight — The flashing on the chimney might leak when high wind gusts pull it off from your roof or chimney, or maybe if the sealant is damaged. Skylights are more challenging to analyze. A leak might just only be condensation at first glance. But, a damaged skylight or weathered seals can certainly result in a leak.

Valleys — Valleys are the small guttering that travels down the roof’s interior angles. The damage to the flashing could result from tiles lifting, a buildup of fungus, or inadequate cleaning. Given that most rainwater will be flowing down these valleys due to gravity, it is important to ensure they are not defective.

Ice dams — When melted snow freezes again on the roof, ice dams are formed. The resulting walls don’t permit other roof runoff to flow to your rain guttering or at least drain off your roof surface.

Shallow slope/insufficient roof pitch — Roofs with shallow slopes are vulnerable to wind damage just as much as flat roofs. In addition, they usually don’t offer good run-off in rainy locations.

Re-tiling increases the value of the property.

No one wants to buy a house and end up spending thousands of pounds to install a new roof after a year or two.

Save on repairs

A well-maintained roof can save you a lot of money on repairs that could result from a sudden storm in the neighborhood that could leave your home submerged during heavy rains. It is much better to get your roof repaired or replaced before it gets too damaged.

New roof cost breakdown

Re-roofing your house can be a daunting home improvement project, but by following a few guidelines and a good idea of what to expect, it doesn’t have to break the bank.

The following breakdown will cover simple “gable style” (up and over) roofs. The price is determined by:

    • Cost of materials: This could include roof tiles, ridge tiles, batons, felt, fixings, sand/cement, cement under cloak, and more. A generally starting point is £1,200.
    • Scaffolding costs: £900.
    • Waste/skip hire costs: £184 for a 6-yard skip and £216 for an 8-yard skip.
    • Labor costs: This is variable and will depend on where you are located. A good rough starting point is £250/day for both a roofer and laborer.
    • Company profits: This will be rolled into the total price and can cover things like insurance for the workers, sick pay, administrative costs, advertising, vehicles, etc. This cost is likely around £300/day.
    • Optional extras: This cost would encompass anything that could replace, but when push comes to shove doesn’t need to be. This can include replacing pipe sleeves and other leadwork along with the roof tiles, repoint chimney, replace fascia, soffits, and rainwater guttering, installing roof tile vents or rigid eaves felt, and replace soil pipe sleeves. Depending upon the amount of extra work done, this figure could reach several thousand pounds.

Some of these figures can be offset, especially on the materials side. If you have a slate roof that’s generally in good repair, a large portion of the tiles might be able to be reused and reduce the overall cost to reroof your house.

Factors that can increase new roof prices

Naturally, a larger or more complex roof design will increase the complexity and, therefore, the project’s cost, but this is hardly something that one can avoid. Bellow, you can see the most important factors that can increase the cost of a new roof.

    • Materials (timber, OSB boards, plywood, joist hangers, restraint straps, nails, screws, square washes, steel nuts, timber connectors, high tensile bolts, coach bolts)
    • Size of tiles (smaller tiles take more tile to install and therefore increase labor fees)
    • Type of tiles (natural slate tiles cost significantly more)
    • Additional work hours.

Re-roofing grants

The cost to reroof a house may all look a bit much. However, you can always get in touch with your council, as you may be eligible for a grant from your Local Authority, especially if you are obliged to opt for a more expensive design in keeping with the neighborhood aesthetic.

The council could also guide you towards the best roof replacement experts to cut on the cost of roofing and inform you on whether or not a certain roofing alteration is worth the investment.

How to reduce roof replacement costs

Do your own research.

Before contacting any roofer with your requirements, try to understand the complexity and size of your project first. Knowing the volume of roofing materials that are needed will help you get the most accurate quotes. One “square” equals 100 square feet of roofing material. Also, keep in mind that the installation and disposal fees are usually included in the estimates you will receive.

Shop Around

Try to get quotes from various roofers to find the best offer. Be suspicious of very low bids as many roofers ignore customer satisfaction when working on a reroofing project, as it is usually a one-off job. Be extremely careful who you hire. Get references from people you trust, check their reputation online and always hire certified installers. Also, make sure that the roofer/roofing company you hire offers a warranty on materials and installation.

Pick the right time

Avoid scheduling your roof replacement in late summer and fall. The best time is usually winter and spring when roofers are less busy. You will get lower bids or off-season discounts at this time of the year.

Use your home insurance.

If you have insurance for your home, it usually covers roof damage when it is not caused by neglect. Try to get the advantage of your home insurance if your roof got damaged by a hailstorm or snowfall, as your insurer may pay for either all or part of the roof replacement cost.

Do part of the work yourself.

If you have the skills, the proper equipment, the time, and are not afraid of heights, you can remove the old roofing yourself, which will lower the costs. Talk to your contractor first about breaking out the fork and roof jacks. It is heavy and dangerous work, and you may have to take care of the disposal of the old materials yourself.

Consider installing an overlay.

A roofing overlay is an alternative to roof replacement when there is a limited budget. This option applies only if you have not installed an overlay before. An overlay involves installing new shingles on top of the existing ones.  You get to keep your old roof and reduce spend this way, as overlaying takes fewer labor hours.

 A word of caution about overlays as they are not always the best solution: new singles tend to last less than the manufacturer’s warranty due to extra heat trapped by the added layers. You add extra weight to your roof, endangering the structural integrity of your house.  Furthermore, overlays do not always look great, making it difficult to inspect the deck’s condition when reroofing and reducing resale value.

The benefits of using professional roofing services

The role and position of the roof make it a susceptible component of the house. As such, you must give the job to a qualified roofing contractor to ensure maximum safety and efficiency.

Having a roofing expert inspect your roof regularly and do minor repairs can help prevent further damages and save you a lot of money. Furthermore, even though the cost of doing a lot of minor roof repairs constantly could easily add up to the cost of a new roof, it is still a great investment that increases the value of a property.

Why Should I Get a New Roof?

The reasons for getting a new roof are rather straightforward;

  • Leaks after a Rainstorm
  • Missing or Cracked Shingles
  • Evidence of Decay or Rot
  • Leaks around Chimney
  • Stains on Interior Ceilings and Walls

You can conduct your own roof inspection first to spot any of the above conditions. If you see evidence of decaying or the first signs of a roof falling apart, then you’ll need to contact a reputable roofer.

How Do I Select the Right Roofer?

First, you will need to go to a respected source of roofing contractors, such as those found in Roofing Associations located in your state. The businesses that register with the roofing associations must meet certain standards and have practiced for a period of time. Beware of roofers who have no connections to roofing associations, particularly ones that show up after a storm.

Once you have found a selection of reputable roofing companies, you can then separate them by their rates and services until you find one that meets your specific needs.

Do They Have Insurance?

In case of an accident, are the employees covered by insurance? You do not want to wind up having to pay for something that you didn’t cause. Reputable roofers cover their employees with insurance in cases of accidents and the like to protect you.

How Long to Install My New Roof

Unless you have a huge home, installing a new asphalt shingle roof generally takes one to two days. Naturally, there may be delays due to weather or unforeseen events, but for normal size homes, they may very well do it in a single day.

Are Metal Roofs Better than Standard Asphalt Shingles?

Yes. Metal roofs are generally fireproof and can withstand impacts that would penetrate an ordinary asphalt shingle roof. However, they are also much more expensive as well. Depending on how expensive it is to remove your old roof, a metal one generally costs twice as much and will take up to four times longer to install.

Are Warranties an Indication of How Long the Roof will Last?

No. Since the warranties are pro-rated over time, they will cover less as the years go by.

Can I Verify if who installed my New Roof Correctly?

Yes. You can call a local or state government representative that will inspect your home for free to see if the roofer followed all the required rules and regulations. All states have had issues with bad roofing companies before, so they will have a mechanism to inspect homes after a new roof has been installed.
