You should inspect your roof at least once a year, to check there are no leaks or infestations. It’s best to do this just after it has rained, so leaks are as obvious as possible. You may find over a period of time there is a build up of moss on the roof, this should be cleaned so rain water has a clear path to the guttering.

Most material warranties come from the waterproofing layer manufacturers, and can last between 5 and 20 years. If your roofing contractor is on the manufacturer’s installer list, it might cover their work. It’s important that you always read through all the information given to you about your warranty so you know exactly what is included.

There are a few reasons why commercial buildings often have flat roofs. Lots of people argue that flat roofs aren’t as attractive as pitched roofs, which is why it’s uncommon to see a residential property with an entirely flat roof. Lots of commercial buildings don’t need to look attractive, so go for flat roofs because they’re cheaper.

Flat roofs tend to be less expensive than pitched roofs, especially for large, broad commercial buildings. Some commercial buildings simply couldn’t have a pitched roof because their width would mean that the roof would have to be extremely high. Flat roofs are also cost-effective for commercial buildings because it means that air conditioning and ventilation units can go on the roof, saving space in and around the building.

Commercial buildings also often have flat roofs because they don’t need the loft space that residential properties need. If there’s no need for the space, it doesn’t make sense to spend more money on a pitched roof just to keep the attic space empty. Flat roofs also give the commercial building owner the opportunity to use the space as a smoking area for employees or give access to fire escapes to upper floors.

If you’re having a commercial property build, make sure you speak to the experts about the type of roof that is suitable for you. If you’re planning on having air conditioning or ventilation systems installed within the property, you might be best off with a flat roof – but if you need some extra storage space, a pitched roof might work best for you.

You should inspect your roof twice a year, ideally after rain or snow, to see if it’s draining properly. Also in the Spring to check for damage that may of been caused over the winter months that will need to be put right before the next winter. Have an inspection carried out if you are unsure.

Tar and gravel flat roofs are popular because the gravel weighs down the surface of the roof so it doesn’t blow away and it also protects it from sun damage. The tar makes the roof watertight, so you won’t get any leaks. However, sometimes problems occur and you’ll get cracks and leaks. So how do you repair a tar and gravel flat roof?

If you notice leaking coming through your flat roof, try to find the source of the leak. Since water can travel easily, it might not be where you think it is. The first place to check is the flashing, then any parts of the roof with gravel missing. Once you’ve found the crack, sweep away any remaining gravel and clean the area.

Apply a primer to the area and allow it to dry. Then, apply a tar and gravel roof patch that you can get from most DIY shops. Patch 2-3 inches around the damaged area, creating layers, and ensuring that there aren’t any air bubbles or gaps. Then you should cover the entire patch with gravel.

Before you try to repair a tar and gravel flat roof yourself, consider how much of the roof needs repairing. Professionals often say that if cracks and faults make up 25% or more of the roof, then you should look to replace it. It might be tempting to try and replace your tar and gravel roof yourself, but it’s best left to the specialists. They will ensure that your new roof is watertight and strong enough to withstand sun damage and storms.

How To Replace Flat Roof Fascia

Whatever makes you decide to install your flat roof fascia by yourself and not a professional company, then you must have a clear idea of what to do and do it appropriately. If you lack proper training and experience, we’d recommend you employ a reliable professional to help with the task for the best results and save you some time and money. This step-by-step guide will give a clear insight on how to go about the replacement of your flat roof fascia.

The tools to be incorporated includes the fascia boards, table saw, plane, crimper, clamps, power nailer, compound saw and chalkline.

• Prepare and get all the necessary tools to complete the task before commencing as this would save you time from stopping and going back and forth looking for the next tool needed,

• Install the sheathing and board.

• Fix white fascias with at least 600mm centres ( a foiled fascia needs just 40mm centre) using a marine grade stainless steel plastic headed nails.

• Make a space of up to 10mm between the joints for possible building expansion, using super glue to secure the joints to just a side of the fascia.

• Place this directly on the fascia board’s top (if you’ll be installing ventilation) to create an air pathway.

• Take note that the type of roof to be installed will determine how you’ll have to install the fascia board. For instance, a hip roof permits you to attach the fascia board onto the roof in a quick fashion, whereas a gabled roof may need you to make markings on the board to achieve the right fit.

• Consider the depth of the fascia board as it also play a huge role in the installation of the fascia board. For instance, there’ll be additional weights on tiled roofs that will push up against the board. Therefore, if you do not get the appropriate amount of depth, it could eventually collapse.

Fitting a Velux window into a slate roof is very similar to the way you’d install it in other roof types. All roof windows, whether a Velux-branded one or not, will come with detailed instructions for you to follow if you want to have a go at fitting it yourself. But here are some brief instructions to give you an idea of what’s involved in installing a Velux window into a slate roof:

1. After you’ve removed the Velux window from its packaging, remove the sash (the part that opens) from the frame, according to the manufacturer’s instructions.
2. Next, you need to prepare the opening for the window. You can often cut through the felt, remove one of the battens from under a slate, then slide all the slate tiles into the roof space. You should then make the cut 40-60mm wider than the window, cutting away roof timbers then replacing them with more around the opening to strengthen it.
3. The roof window’s bottom brackets need to be installed on one of the existing battens for the slate roof. One of the slate courses should line up 105mm below the top edge of the batten you use.
4. Then, measure from the top edge of the batten upwards to the height of the window plus 45mm. This is where the top installation batten should be installed, with an overhang of 100mm on each side.
5. Remove the course of slates below the window, trim any excess felt and fold it over the surrounding timber. This helps with waterproofing.
6. Add the insulation collar according to the Velux window manufacturer’s instructions.
7. Place the frame in the opening, adding the brackets according to the instructions. You’ll find that lots of roof windows have pre-drilled holes to make it easy for you.
8. Replace the sash and line up the hinges. Take a look at the opening at the bottom between the sash and the frame – it should be even along the entire width. Remove the sash again to fix the upper brackets according to instructions.
9. Add the underfelt collar for your roof window as instructed by the manufacturer, then replace any slates at the bottom. You might need to cut them to size.
10. Next, add the flashing according to the instructions, along with any parts that are not yet attached, including the hood section and top flashing piece.
11. Replace all the slates around the window, allowing 60-100mm of space between the course of slates above the window and the top of the window to allow for rainwater drainage. Then replace the sash into the frame again.
12. Add the vapour barrier on the inside of the window using the screws provided, then tape it to the existing vapour barrier to prevent moisture from reaching your roof structure.

And that’s it! If you think that sounds a bit complicated, ask a roofer or window installer to fit your roof window into a slate roof for you. You’ll get a better finish and you can be sure that you won’t get any leaks from a botched installation.

How To Repair Roof Leak

Asphalt shingles are the most popular roofing material options for most UK homes in recent times. Thanks to them, roof repair is now all about identifying the leak and sealing it the right way. If you’re a competent DIYer and confident enough to pull this off, then this should be done within a short period of time and saving you money as well. However, if you don’t have the confidence to pull this off, then calling on a professional roofer who can guarantee the best results will be your best bet. In this article, we’ll consider four simple steps you can take to repair an asphalt shingles roof.

✓ Locate the spot of the roof leak. Roof leaks are mostly made evident by water stains on the ceiling. Simply note the spot of this water stain, grab a good pair of binoculars, then go outside to identify the location of the roof leak. Search the area for any curls, cracks, missing shingles or anything that looks odd. Leaks can also occur at any spot where caulking and flashing have been affected or compromised.

✓ Secure curled shingles. To do this, simply brush on a generous amount of asphalt roofing cement to the underside of the shingle and press firmly to set.

✓ Replace damaged or missing shingles. In the event whereby the shingles are cracked, rotten or missing, your best bet would be to have them replaced. Simply remove the damaged shingle then slide in the new one under the one above and align it with those on either side. Once done, you can then secure it with 6d galvanized roofing nails at each corner. After completion, make sure you cover the nail heads with roof cements.

✓ Fix flashing. To do this, simply reseal joints with the help of a caulk gun loaded with roofing cement.
