A roof serves as something which is so much more than just a top of a building. A roof delivers guard from the elements and precipitation, it also helps drain water from a structure, and helps to provide insulation to the structure allowing it to keep the interior of a building cool or warm, according to season.

There are several steps to building a roof

Mount the trusses.

This step requires the building’s wall frames to be completely level, square and plumb. If you are building the roof onto a building that is still a frame you must use ladders or scaffolding. Hoist the trusses onto the roof.

Install temporary braces.

You will need to install temporary braces that the trusses can rest on until the sheathing and permanent bracing are installed, this has to be done before you install the trusses. At the centre of the back wall, nail the bottom half of one two-by-six board that's 16 feet long to the top of the outside wall, making sure you fasten it to a stud.

Install the end trusses.

Install the two end trusses at the front and back of the building, making sure you affix them to the temporary bracing. The batten you take will have to be a bit longer than the distance will separate the trusses.

Install the standard trusses.

According to the instructions provided by the manufacturer, you will first need to install the first standard truss. You will also need to nail it to the batten from the first truss.

Sheath the roof.

Once your trusses permanently braced, you can begin with the sheathing of the roof. Starting from the bottom corner and moving across the bottom, the sheathing is installed lengthwise.

Install the roof cover.

Like the sheathing and underlayment procedures, the roof cover is installed lengthwise from the bottom up. The shingles should be staggered, and they should also overlap at the same time. You will need to work up to the ridge and use a ridge cap shingles to finish the ridge.

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.

How to repair a hole in a flat roof depends on what material your flat roof is made from. If you have an asphalt, felt or EDPM rubber roof, the repairs are quite simple, whereas it’s a bit more tricky if you have a fibreglass flat roof. How to repair a hole in an asphalt flat roof If you’ve got a small hole in your asphalt flat roof, you might get away with using a paint-on fix from a tin. It’s best to use this as a temporary measure to tide you over until you can get in touch with a professional. If the hole is on the flashing, you can add heat-applied flashing tape to it, or use a patch of torched-on roofing felt. There are liquid systems you can use, but usually they’re only available to the trade. Repairing a hole in a felt flat roof It's a similar process to asphalt roofing if you want to repair a hole in a felt flat roof. Use a paint-on fix for a temporary solution, but the best way to repair a hole is to use a torched-on piece of roofing felt to cover the hole and make it watertight again. How to fix a hole in an EDPM rubber flat roof If the hole in a rubber flat roof is small, you may be able to get away with applying some lap sealant to the hole. Only use a small amount, as if you go for a more permanent repair later down the line all of this will need to be scraped off. You can also use a malleable piece of self-adhesive flashing – clean the area, add EDPM primer and stick the patch on from the centre outwards. Add sealant to the edges if you want to give it more water protection. How to fix pin holes in a fibreglass flat roof If you find pin holes in your fibreglass roof, it usually means there wasn’t enough resin used at installation. To repair the holes, you’ll need to sand down the entire roof back to the clear resin. Then clean the area with acetone and apply GRP roofing resin – the acetone ensures that the resin sticks. You might need two coats of resin to get rid of all the holes.

Strong winds can cause extensive damage to unprotected rooftops and in fact tiles act as very suitable protection. The extra weight they provide is great at countering high wind loads and if anything is damaged during severe weather, replacing tiles is straight forward for professional roofers.When you compare this to lightweight materials there’s a significant difference. If you wish to have extra protection, experts recommended having sarking fitted.

Velux windows actually refer to one brand of roof window, which are windows that sit in your roof space and allow light and ventilation into your loft. But how do you install a Velux window? If you’re a competent DIYer, it’s not as difficult as you might think.

You can normally install roof windows entirely from the inside, so you don’t need to get up on your roof or hire costly scaffolding. They come with detailed installation instructions, so as long as you follow them you shouldn’t have much trouble.

Before you start, you’ll need to read up on the Building Regulations and Planning Permission laws. Speak to your local Building Control department if you have any questions.

Firstly, prepare the opening by removing enough tiles or slates from the roof. There’s no need to go out on the roof – access them by cutting away the felt underneath which will give you access to the tiles and battens. Cut away one of the battens from under a tile, then you can slide all the tiles into the roof space. You’ll need to cut away the roof timbers to make the right size opening, then add more timbers to strengthen the ones that are left.

Next, remove the opening sash from the new roof window then fit the frame into the new opening using the brackets provided with the window. Then fit roof flashing between the new window and the roof so you don’t get any leaks. Then lay your tiles back in position around the new Velux window; you’ll probably have to cut some to shape which you can do with an angle grinder. Always cut them on the ground, not in position on the roof.

Lastly, fit the sash back onto the window and you’re done!

If this sounds like too much hard work, plenty of window installers will be able to help you fit a Velux window and will probably be able to provide a much cleaner finish.

Roofing is one of the most significant portions of your household. Not only does it protect the inhabitants from the elements, but it also plays a vital role in the architectural appeal. When people reflect of roofing, they consider various types of tile for the job.

Metal Tiles

When we talk of metal roofs, most of the people think of roofs made of metal panels which are joined together by joints or raised seams. This is often not the case as there are several numbers of obtainable metal roofing products.

Ceramic Tiles

Another popular choice of roofing material is ceramic. Clay tiles are incombustible and fairly sturdy, necessitating scarcer repairs or substitutions than asphalt roofs.

Concrete Tiles

For those that like the look of ceramic tiles, as well as their fire resistance, this may not be the choice, but those who want something a little tougher and less susceptible to cracking when having work done on the roof, there are the best tiles.

Bituminous Tiles

For those that want a lightweight, supple tile that’s easier to fit, there’s the bituminous tile. These types of tiles are made from cellulose fibre or using fibreglass allowing them to be flexible.

Polymer-Sand Tiles

A new-fangled substitute for ceramic tiles is the polymer-sand tile. Created from a combination of sand bound together with polymers, these are very rigid, sturdy tiles are shaped in a mould.

Copper Tile

Copper roofs can be a great choice for many due to their long lifespan. Copper tiles have the ability to last over a century before needing replacement.

Composite Tile

Another newer roofing tile is the composite. This is a multi-layered tile that is made using metal, acrylic and stone granules.

Stone Tiles

This is one of the oldest forms of roofing tiles that you can get out there. It is also one of the longest-lasting tiles on the market as well, with some roofs lasting well over 100 years.

If your existing roof is still in good condition but the membrane is getting old, it’s often not worth exposing the structure to the weather whilst the contractor strips off the old membranes. The contractor will leave them in place to act as a base layer for a new roofing system. As long as there are no other problems with your roof, then overlaying is a good way to replace your flat roof.If you have any more questions about flat roofing that aren’t listed here, fill out our form to ask a contractor.

How To Replace A Broken Roof Tile?

If you have a broken roof tile on your property, the next logical step to take is having it replaced as soon as you can. However, this is not the simplest of tasks so you might need some guidance if you wish to do it yourself. If you lack the confidence needed to pull this off as it involves working at height, then we’d strongly recommend you hire the services of a reliable roofing contractor or company who can guarantee the best results for help. In this guide, we’re going to walk you through the processes involved in the replacement of broken tiles. Let’s have a look!

✓ Match your roof tiles perfectly. The most frequently used roof tiles are concrete and terracotta. They may look all similar but they can actually vary in shapes, length as well as thickness. To replace a broken tile, you must first make sure that it’s the same type of tile so it doesn’t interfere with the flow of your roof which can lead to further damage.

✓ Climb on to the roof. Make use of a strong and stable ladder to do this. If you’re not comfortable with heights, simply call in a professional. Falling of the roof would be more expensive.

✓ Remove the broken tile. Lift up the overlapping tile next to the broken tile in such a way to enable an easy removal of the broken one. If you’re not able to life them, then they probably have nails securing them in place. Remove these nails to proceed.

✓ Replace the broken tile with the new one. To do this, simply lift up the bottom tiles from the above row and then slide the new tile back in place. If the tiles have been nailed, make sure you also drive a nail through the hole in the new tile into the timber roof batten.
