How Often Do Flat Roofs Need Replacing?

When a flat roof needs to be replaced is determined by a number of factors which includes the roof’s exposure to the weather, the condition and age of the roofing materials as well as the construction of the roof. However, with proper maintenance and regular inspection, they should be used for nothing less than 50 years. There are some commonly used types of flat roofs which includes Felt flat roof as well as a GRP flat roof.

Felt Flat Roof

The lifespan of a felt flat roof also varies depending on the quality and grade of the felt roof incorporated. This can make the roof last within the range of 2 to 20 years. More often than not, felt flat roofs are usually installed in such a way to keep the costs down which implies the grades of felts that are mostly used are the economical ones implying a very short lifespan.

In the event whereby a premium grade of felt is incorporated in constructing a roof by professional contractors, will be guaranteed by the manufacturer to last between 10 to 20 years.

One of the major causes of a short lifespan in felts is leaks which should be regularly inspected and repaired once identified. If not, the roof will gradually deteriorate and become a lot weaker due to the action of the sun. However, when a felt roof starts to leak, it’s usually a sign that’s approaching the end of its lifespan and a replacement should be taken into account.

GRP Flat Roof

The GRP flat roof or fibreglass flat roof usually comes with a manufacturer’s guarantee of 20 years and is expected to have a lifespan of a minimum of an additional 10 years.

Unlike felt roofs, they’re more resistant to leaks. However, they should also be regularly inspected for leaks which are caused mostly as a result of installation error rather than the GRP roofing approaching the end of its useful life. If the GRP roof repair does not totally resolve the leak, you should start considering a replacement.

In general, no – you don’t need planning permission for a Velux window. The Planning Portal says that you don’t need to apply for planning permission to install a roof window if the following conditions are met:

• A roof window must not protrude more than 150 millimetres above the existing roof plane
No roof window or any other alteration can be higher than the highest part of the roof or stand out above the roof ridge
• Side-facing windows must have obscure glazing to protect privacy of neighbours and, if they open, they must be 1.7 metres above the floor of the room in which they are installed

You don’t need to apply for planning permission for a roof window because they are covered under permitted development rights. However, if you’re a leaseholder or you live in a building where your local authority has made an Article 4 Direction, you will have to apply. Usually, an Article 4 Direction is made when you live in a conservation area where any external home improvements could affect the character and look of the area. Luckily, there are special Velux windows that are designed to be more likely to be accepted by your local planning authority. They’re called conservation windows and, although there’s still no guarantee that they will be accepted, they are designed to look more traditional. Even if you don’t need planning permission for your roof window, you still need to follow any relevant building regulations for your local authority. The most important parts for Velux windows are section J and section L of building regulations, which refer to energy efficiency, thermal insulation and fire protection.

If your boiler is leaking, there are some checks that you can do yourself. However, you should never attempt to repair your boiler yourself – only a Gas Safe-registered engineer should conduct repairs.

There are 3 main reasons why your boiler might be leaking: there’s a pressure valve fault, a temperature valve leak or corrosion in the system. An engineer will be able to spot the problem quickly, but in the meantime there are a few things you can do:

Check the pipe fittings

If your boiler is leaking water around the pipe fittings, it could be an installation fault and you should get in touch with the engineer that fitted it. You can check the pipe fittings by drying the area then waiting to see if the water appears again. If it does, you may be able to do a ¼ turn of the pipe to stop it. However, you should still call the engineer that installed it to ask them to check the PTFE tape on the inside.

Inspect the seals

Over time, the rubber seals on a boiler can start to perish, so if you have an old boiler this could be the source of your leak. If you have a new boiler, it could be caused by your boiler running over pressure.

Heat exchanger corrosion

Unfortunately, if a boiler engineer discovers that the boiler is leaking water from the heat exchanger, this is the end of the road for your system. The heat exchanger is the most expensive part of your boiler, so it makes more financial sense to replace your boiler with a newer, more efficient model rather than try to replace it.

• Climate - If your window faces south, it will be subject to direct sunlight for a lot of the day. This tends to cause the sealed unit to fail more quickly – a south-facing window may last between 10-25 years. This is because the spacer bars will twist as the temperature rises and causes the adhesive holding them together to eventually fail.
• Moisture - Windows in kitchens and bathrooms tend to fail more quickly because they come into contact with moisture more often. For example, if water gets on your windowsill when you shower, the seal around the glass will come loose more quickly if it’s constantly wet.

How Much Plasterboard Do I Need?

Although many people especially contractors have a tough time estimating the number of drywall or plasterboard needed to complete a project, it’s a rather simple task if all factors are taken into consideration. If you’re able to follow the same procedures taken by professionals to count dry wall sheets, you’ll be in the right direction. Let’s have a look at the procedures to follow!

lTake Square Footage Measurement

• Measure the square footage of the area where the plasterboard will be fitted.

• Multiply the height by the width of each wall or ceiling area.

• Add all quantities to obtain a total square-foot amount.

lCalculate Drywall Sheets

• To calculate the number of drywall or plasterboard sheet is very simple once you’ve gotten the total square footage.

• To get started, simply divide the total square footage of area by 32 (that’s if you are using a 4 by 8 sheets) or you can also make use of 48 to make the division (only if you’re making use of the 4 by 12 sheets).

• The answer you get after the division will give you the full number of plasterboard sheets that’s required to complete the project.

We’d recommend you include an extra 10 to 15 percent of whatever you calculate to take care of the possible odd cuts and wastages. This implies that if your total area is 1600 square feet while incorporating 4 by 8 sheets, simply divide 1600 by 32 which equals 50 sheets, now take 10% of 50 which equals 5, then add back the 5 extra to the 50 sheets earlier calculated to get 55 sheets. If you wish to estimate the cost, simply multiply the number of sheets gotten by the price per sheet. Do not forget to include delivery charges and local taxes.

Also commonly referred to as brown rot, dry rot simply means a decay of the root as a result of fungi which may negatively impact the wooden structures in the interior or exterior of your home or property. When the dry rot happens, the fungi present breaks down the cellulose as well as hemicellulose – the components which are responsible for the strength and resilience of the wood. Consequently, the wood is left weakened and brittle while also appearing a bit blocky. Most often than not, dry rot affects damp timber, primarily with a moisture content that’s more than 20 percent. As a result of this, any dry rot eradication strategy should have the removal of the source of moisture to form the core of its activities. So, how can you identify dry rot? Let’s take a look!

• Examine the wood. At first, the fungus appears a lot similar to cotton wool and may also possess water droplets on its surface if there is a very humid surrounding.
• Look out for shrunken or sunken wood.
• Identify darkening and cracks in the structure of the wood.
• Identify affect wood that features flat skin-like grown that may appear like the exterior of a mushroom with shades of silver and grey. Most times, patterned with patches of light purple or yellow which easily peels.

Dry rot can be treated in a number of ways which includes epoxy treatments, commercial anti-freeze as well as copper compounds. The epoxy treatment simply means the act of filling in channels within the damaged wooden structure with an epoxy treatment to eliminate the rot and strengthen the structure of the wood. The commercial antifreeze is the treatment of the rot with antifreeze to kill the fungus and prevent further growth.

What Is The Smallest Opening For Bifold Doors?

Generally, bifold doors comes in a wide range of sizes and configurations. So if you’re looking to install them in your home, the opening size required will depend on multiple influencing factors. However, the question we’re going to look at here is the smallest opening for bifold doors.

First and foremost, let’s consider the size of bifold doors as learning about how big or small bifold doors can play a key role in helping you determine the size of bifold door you’ll need. Generally, the size of bifold doors will vary largely depending on the manufacturer, but they are usually within the range of 6.8 feet and 7 feet in height. The width, however, will be determined by the number of door panels you’d like to use but several configurations are designed in such a way that they can be installed in openings of about 1.8m and above. For each door panel, the size are usually between 500 and 1000mm in width. As a result, if you decide to opt for door panels with a width of 700mm, you’ll need to get about 3 of the door panels in order to install in an aperture that’s wider than 1.8m. What’s more? Door panels can also be custom made especially if the size you need isn’t available.

So with that in mind, what’s the smallest opening for bifold doors? The bifold door’s minimum width is 1400mm. And in order to install a bifold door to fill this size, you’ll require two individual door panels that’s 700mm in width. Building them any smaller than the minimum width will be unwise as this will make them bind when closing.

In most areas, you will not need planning permission. However, if the property is listed or in a conservation area, you will need listed building consent or planning permission to paint the exterior. A surveyor or architect's advice will be invaluable as they can help with this process.
