How To Replace Flat Roof Felt

Also referred to as tar paper, roofing felt is installed underneath the roof’s shingles to help deny water access to your home. Installing the roofing felt in overlapping layers builds a water barrier in situations whereby the weather damages or blows away the shingles. Although the application of a roofing felt on a flat roof is relatively easier and safer than working on a peaked roof, it’s advisable to take enough care and precautions. If you lack proper training and experience for this task, we’d recommend you employ a reliable professional to guarantee the best results and save you from further headaches especially in cases whereby unfortunate errors are made. This step by step guide will give you a good insight into the flat roof felt replacement process.

• Take a measurement of the width and length of the roof.

• Calculate the square footage by multiplying the numbers.

• Multiply the square footage gotten by three (it’s advisable to install three layers of roofing felt to create a really strong weather barrier).

• Use a claw hammer to remove the existing roofing felt.

• Use utility knife to cut the new felt to fit the length of the roof.

• Place the first piece along the roof’s edge and use a hammer tacker to tack the felt in place with staples or galvanized nails and hammer.

• Put the staples or nails at every 6 inches along the side touching the roof’s edge as well as down the short sides.

• Repeat the same process for the second piece, laying it out beside the first row of felt.

• Cut a piece of felt to the appropriate length using a utility knife to begin the second layer of roofing felt, and cutting it in half, lengthwise.

• Apply construction adhesive along the first row using a trowel.

• Press the first piece for the second layer onto the adhesive. Repeat this process until the roof is covered with a second layer

• Apply construction adhesive over the second layer to install the third layer. Begin with a full piece of felt without cutting it in half.

• Overlap each piece by 2 inches until you’ve completely installed the third layer.

Leaves, twigs and moss all have one thing in common which often annoys home and property owners - they are the three main materials that negatively impacts the proper functioning of a roof guttering system. The major cause of water drainage problems for most homes and buildings are these organic materials. Wondering how some leaves and few twigs can cause such a big problem? Over time there’ll be a gradual build up of the natural debris in your gutter system which starts to rot and turn  to a thick and muddy goo which obstructs the flow of water in your drainage. As a result, there’s the need to make sure that your gutters are thoroughly cleaned at least twice annually in order to prevent bigger issues that can be caused by the blockage of a drainage system.

So if you’re considering getting your gutters cleaned by a professional, you’d probably be interested in know just how it’s going to cost. Well, there’s not straightforward and simple answer to this question as there are a number of factors that contributes to the final cleaning cost of your gutters.

In general, in the UK, the average cost for cleaning of gutter is usually around £18 to about £25 per hour. However, you can also be quoted a day rate which is usually ranging between £150 to £200 per day.

The factors that can affect gutter cleaning price includes the type of your property (such as a terraced, end of terraced, detached and semi detached homes) which possesses a varying gutter cleaning price largely due to their size differences, the height of the building ( if you require the service for a property located on the second floor of a building, this would be a bit higher than if it were to be on the ground floor) as well as additional requests.

The roof is a particularly important part of the home, providing weather and water protection. Therefore, it’s important to regularly check your guttering system and clean out any debris that could cause blockages.Advice given is to consider having a mesh gutter guard to prevent the build-up of leaves and other debris, especially if you want to harvest rainwater.

It’s relatively simple to remove a Velux window, whether it’s Velux-branded or is another brand of roof window. Here is a breakdown of the steps you’ll need to take to remove a roof window:

1. Remove the sash (opening part) from the roof window frame. Usually there are screws in the hinges to loosen or a button to press and lift out.
2. Next, remove the tiles or slates from around the window frame along with the flashing.
3. Unscrew all the brackets around the window frame and lift out the frame.

It’s that simple! You can do all of this from inside your home – there's no need to climb on the roof. Removing the glass pane from a Velux window, for example if it has blown, is a more difficult job and should be left to a professional. It involves removing the sash from the roof window frame and then removing the surrounding parts of the sash to lift out the sealed unit. They will then place the new glazed unit into the sash frame before securing all the parts back onto the sash and fitting it back into the roof window frame.

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.

It can be easy to repair a felt flat roof depending on the problem. If you’ve got an old-style pour-and-roll felt flat roof, you might be starting to run into problems, but even if you have a newer torch-on felt roof, issues can occur. You might find cracks, lifting, leaking flashings or dips and hollows in the felt. Luckily, there are some easy fixes – but the best thing to do to prolong the life of your felt flat roof is to get a professional to look at it.

If your felt flat roof only needs a small repair, you might be able to get away with using a paint-on fix from a tin that you just brush on. However, if you want a more permanent fix, you’ll need a few more tools and supplies.

You can use a patch of torched-on roofing felt over the crack or leak, but if your flat roof is very damaged or wet it might not take it. You can also buy liquid systems for felt roofs, but again, there is a possibility that your roof might not take it. Also most of the high-quality liquid systems are only available for trade customers, so you might be better off asking a roofing pro to do it for you.

It depends on the material you use, but if your flat roof is installed correctly it should last for at least 10 years, and at least 20 if a material other than felt is used. Always question a roofing company when they quote to find out what materials they use and what guarantee's they offer.

Yes, it’s a dirty job, but every homeowner out there has got to do it! Your gutter needs to be free of dead leaves, birds’ nest and other debris as well as being through clean in order to perform its functions effectively. It’s just a part of the responsibilities that comes with owning a home. Dry leaves, tree branches and other materials build up in your gutters overtime especially during the dry summer and you won’t notice until the point where your gutters start overflowing during the first main rain of the season.

In the event whereby your dirty and clogged gutter is left unattended to, this can lead to several issues like a leaky gutter and mold, leaky roof and basements,cracked foundation, driveway and yard damage and several more which will definitely make you incur more unnecessary expenses. So the question is, how often should the gutters be cleaned? The answer is, it depends. According to several experts, gutters should be cleaned at least twice a year - which is once in the late spring and once in the late summer or early fall. However, there are a couple of factors that may make you have a rethink.

If you happen to have a pine tree growing above your house, it’ll be wise to consider inspecting your gutters every 3 months. This is because pine trees shed needles year-round and they usually have a lot of these needles to shed. In the situation whereby you’re located at a higher elevation, ice is will most likely be your greatest source of concern. Making sure that your gutters remain clean throughout the winter can be quite a headache, but damage to your roof cause by ice can be an even greater pain. Prevention is always better than cure.
