Blisters are most common on membrane roofing systems. Lots of contractors will tell you that if there are no signs of further damage, there might not be any need to repair flat roof blisters. They form when pockets of air or water get trapped between layers of the roof’s membrane or between the membrane and the frame. When the sun is out and it heats the pockets expand and stretch the membrane. If you do want to repair your flat roof blisters, there are a few ways to go about it.

If you have a membrane flat roof, cut away the membrane until you reach a place where the membrane is still stuck tightly to the roof. Reapply as many new membrane layers as you cut away over the blistered area. You might even need to do more. To make sure your patch remains watertight, you’ll need to leave at least 6 inches around the edges of the blister.

If you’ve got a felt roof, you can cut an X shape through the blister. Peel back the triangles that you’ve made and let the timber frame dry for a while (so don’t do this when rain is forecast!). Then, coat the area with lots of bitumen adhesive and leave it to dry until it feels tacky. Then press down the triangles of felt firmly into the adhesive.

After that, you’ll need to add more bitumen adhesive to the cuts you made. If you’ve got any spare roofing felt, cut a square that’s about 100mm bigger than the cuts then lay this over the adhesive. If you’ve not got any felt, it’s cheaper to use a self-adhesive flashing strip. Once you’ve laid the strip or patch over, seal the edges with more bitumen adhesive.

Chimney liners are a very important component of the chimney, but the fact is most home and property owners either continue to overlook them or aren’t even aware of their existence. This is, however, quite understandable given the fact that they usually last a long period of time – more than 50 years. To ensure that they last that long, the question that arises is, do chimney liners need to be swept and cleaned? The short and simple answer to this question is yes, chimney liners definitely needs to be cleaned on a frequent basis. A chimney liner happens to be an essential part of your chimney. When it’s not cleaned, it tends to accumulate dust, soot and dirt which can give rise to a number of problems you’d rather want to avoid. Chimney liner are able to provide adequate protection to your flue but even at that the water, creosote and other contaminant build up can make the liner to deteriorate, and making it unsafe for usage. In other words, contrary to several belief, chimney liners do need the same amount of cleaning as chimneys without liners. Failure to sweep your chimney liners can give rise to the following problems:

• Creosote buildup. If your main source of fire is wood, then you’ll definitely have creosote present in your chimney. This is highly combustible and its buildup may lead to fire outbreak.
• Carbon monoxide poisoning. Carbon monoxide is said to be on the rise by NCBI and its primarily generated from heating systems which are terribly ventilated as a result of uncleaned or dirty chimneys.

How you install commercial rubber roofing is similar to fitting it on a residential property, except that the area that’s covered is likely to be bigger. With commercial properties, you should always leave any maintenance and repair works to the professionals – whether you own or lease the property, you could invalidate any insurance if you try to install rubber roofing yourself. We’ll outline the steps roofers will take when installing rubber roofing on a commercial property.

Firstly, the installers will remove any existing coverings and clean and dry the surface thoroughly. This is vital in ensuring that the rubber will stick. They will then unwrap the EDPM rubber membrane and leave it to rest until it’s fully expanded. On a warm day this may take around half an hour.

Next, the roofers will work with half a sheet of rubber at a time and adhere it to the roof surface. They may use a water-based adhesive which they will spread onto the roof in sections, then roll the membrane onto the surface before moving onto the next section. If they’re using a bonded adhesive, they will apply it to both the roof and the rubber and leave it to dry until it’s tacky before extending the membrane.

Once the EDPM rubber is rolled out, the installers will brush the surface with a large broom to get rid of bubbles and provide a stronger bond. Then they will work of the edges, applying adhesive to roof and walls edges, sealing corners and creating watertight seals. They’ll also tidy up any excess membrane and seal all the trims.

As long as it’s installed correctly, your commercial rubber roofing should last you decades without any repairs needed. It’s always best to inspect your roof regularly to spot any damage before it becomes a bigger problem.

Whether you’re liable for a leaking roof in a commercial property will depend on your ownership status and any contracts. Of course, if you own a standalone commercial property, it would make it your responsibility to repair to leaking roof. But if you own an office within a building, you should check your paperwork to see whether you are responsible for some or all of a leaking roof.

If you’re a tenant in a commercial property, things get a bit more complicated. Lots of commercial leases are FRI, or Full Repairing and Insuring leases, which means that the tenant is responsible for all external and internal maintenance and insuring the building. It means that it’s vital that you read through your tenancy agreement in full before signing it and seek legal advice if you think you need it. If your lease is an FRI lease, you are liable for a leaking roof in your commercial property.

It’s important to ensure that you have a schedule of condition for the property, which will mean that you only have to restore the commercial property back to the condition that it was in when you took over. It’s also worth getting the roof inspected before you sign the lease, as if there is any damage before you sign the landlord may be responsible.

The best way to avoid having to pay for a leaking roof in a commercial property is prevention. If you are liable for repairs and maintenance, make sure you have the roof inspected regularly by a reputable company to avoid having to pay for costly repairs when disaster strikes.

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.

How Much Is It To Replace A Garage Roof?

The size of your garage will be the main determinant of the cost of a new garage roof. However, the present condition of your roof structure as well as the type of roof covering preferred are also huge factors. In the UK, the cost of a garage roof replacement will be within the range of £700 to £3600.

The first step a pro will take is to remove the existing roofing while also making sure that the timber structure is in a good condition. In the event whereby the timber is rotten, it will need to be replaced before the installation of a new roof. If the garage roof sheets needs a replacement, you’ll have to spend about £30 to £50 per each garage roof sheets. Individual plywood sheet has around 2.4m x 1.2m in measurement and whose price should also be included in the final cost.

The above information applies only to standard roofing for garage roofs with flat roofs being made of bitumen felt and asphalt. In recent times, this is no longer the case with several more options available. Today, EPDM and GRP fibreglass have rapidly become very popular amongst several homeowners in the country. It’s also important to note that modern roofing has greatly advanced over the years even though both EPDM garage roofs and GRP fibreglass garage roofs are way better and of more quality when compared to felt and asphalt roofs. And thanks to modern technology, modern garage roofing possesses a longer life expectancy and as result, are a lot costlier than the conventional ones.

For a medium size single garage (2.7m x 5.5m), the cost for a felt roof per square metre is between £40 to £70, while that of a fiberglass roof and an EPDM rubber roof is between £90 to £110 and £70 to £100 respectively.

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.
