how to clean a roof?

How To Clean A Roof?

If you’re planning to clean your roof, but don’t know where to start, you’ve come to the right place! There are different types of roofs available in the market today and the method used in cleaning one can be largely different from the other. As a result, we’re only going to look at one of the common types of roofs you’ll find in the UK - the Asphalt shingle roof tiles. This roof type is very common and for a good reason. Not only are they visually appealing but they’re also hugely versatile by design which enables them to be adaptable to varying shapes, angles as well as forms depending on your preference or needs. With all the benefits that can be derived from asphalt shingle, they however, need to be properly maintained to help retain their good looks.

To clean your asphalt shingles, you’ll most likely require some type of chemicals especially when dealing with algae stains and some other visual problems. Therefore, make sure you purchase a product marked safe to be used on this type of roof and not those only proven to remove moss and algae stains. Mix the chemical cleaner with a gallon of water and a quart of bleach or as instructed by the manufacturer. Pour the mixture inside a pump-style garden sprayer and mix thoroughly. When done, climb up on the roof and spray as good as you can. Upon completion of spraying the roof with the mixture, then allow to work its magic for some time - about 15 minutes or thereabout should be good.

After that, you can make use of a garden hose to spray down the roof and wash down the mixture entirely. If some stains remain, use a brush to gently wipe the tiles individually.

how to repair roof leak?

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.

what happens if you don't clean your gutters?

Gutters are a crucial component of any roofing system. They’re designed in such a way to protect your home or property from serious water damage, but keeping them clean and in good condition is something that’s almost always forgotten or ignored. Do not be deceived even when rain water is still running from them or they don’t appear to be clogged. Failure to clean maintain your gutters can lead to a wide range of outcomes and they aren’t so pretty. According to experts, gutter cleaning should be done twice a year - once in the spring and once in the fall. In order to help you realize the importance of cleaning your gutters, we’ll look at some of the possible outcomes of a neglected gutter.

  • Leaky roof. If your gutters get clogged and cannot move water away from your home, it begins to build up on the roof and eventually lead to damages like rot and mold. As the damages spread, the end result could be a severe damage to the attic and supports.
  • Damaged foundation. If the gutters are not functioning as they should, water saturation becomes a great threat to the foundation of your home or property. The concrete will crack or wood rots and you can also end up with mold.
  • Creepy crawler infestation. Wherever you have stagnant water, there are also bugs. This is because they love the wet and moisture-filled gutters. You get unwanted visitors like carpenter ants, roaches and mosquitoes, just to mention a few.
  • Driveway and path damage. When the downspouts aren’t directing the water to the appropriate spot, the excess that comes in contact with these surfaces can lead to cracks or sagging.
How to clean soffits and fascias?

As long as you can access them safely, it’s fairly easy to clean soffits and fascias. Using a sponge and warm water to scrub them is a good way to get off most types of dirt. You might want to add detergent or bleach to the water to make it more effective.

Once you’ve scrubbed your soffits and fascias, rinse them with clean water to make sure you’ve got all of the dirt and detergent off.

How to find a commercial roofer near me?

To find a commercial roofer near you, you could ask other tenants or property owners whether they can recommend a company. If you choose a company that’s been recommended to you, make sure you do your own research into them before you decide to engage them; you can check whether they have social media pages, reviews and examples of previous work. If the company has a Quotatis profile, you’ll find genuine reviews from their customers there, including photos of work they’ve completed.

Another option is to do your own search online. These days lots of companies will have their own website and you may be able to make an enquiry through there without even having to call them. Again, you should always check out their qualifications, previous work and reviews before deciding to go with them.

Or, you could let Quotatis do the work for you. Simply tell us about your commercial roofing project and where the property is and we’ll put you in touch with up to 4 reputable commercial roofers that will be able to offer you a free, no-obligation quote. You can check out their reviews, qualifications, insurance and photos of work on their profile which we’ll send to you in an email when we’ve matched you. The roofing companies should contact you first, but if they don’t we’ll give you all their details so you can introduce yourself.

how to clean roof lights?

How To Clean Roof Lights

If you have existing roof lights or perhaps you’re about to have them installed, it’s important to know just how to have them cleaned, even if you wouldn’t be doing it yourself. Generally, glass roof lights fitted in flat roof applications are more likely to be a major victim of staining and discolouration by several elements like rainwater, bird droppings, vehicle exhaust pollutants as well as tree sap. Therefore, just like any other parts of your home, periodic inspection of the units as well as regular cleaning is highly advised to help maintain their top performance for a lengthy period of time.

Firstly, when installing the roof lights, it’ll be helpful if its fitted at the right pitch so as to help keep the exterior clean as it enables the elements such as rainwater to run off the surface naturally. Cleaning roof lights involves working at height which can be very dangerous. Therefore, if you lack the skill and confidence to pull this off, it’s advisable to hire the services of a professional who can guarantee the best results for help. In this article, we aim to give you a good insight into how the roof light cleaning process works. Let’s have a look!

Rooflight Interior Cleaning

✓ Spread plastic under the roof light to catch dirt and spills

✓ Dust to wipe clear all loose dirt and cobwebs.

✓ Use a squeegee with a warm soapy water or any other glass cleaning product to clean the glass ( steer clear of any harsh chemicals or abrasive cleaners)

✓ Dry the roof light with a soft and lint-free cloth.

Rooflight Exterior Cleaning

✓ Access the roof safely with a specialist ladder

✓ Put mild detergent into a bucket and carry up to the roof before filling with warm water from a hosepipe

✓ Use the soapy water and a non-abrasive cloth or squeegee to clean the roof light, its surroundings as well as fixings.

how much is a new flat roof?

How Much Is A New Flat Roof

What is a home without a roof to keep out the elements? Being the first line of defence against intense sun, rain, wind and more, implies they require enough care and attention to keep them in a top condition. Therefore, whether you need a new flat roof or just to replace some tiles, you’d be interested in knowing how much it would cost you to get a new roof before you start making the necessary plans. Here, we’ll give you an idea on the cost of a new flat roof and how you can estimate yours based on your unique requirements.

The size of your roof as well as the material to be used are the two main determinants of any flat roof project’s cost. For instance, a four bedroom detached home’s slate roof will be more expensive than a felted flat roof for a small or standard garage. Generally, in the UK, the average cost for replacing a flat roof will range between £5000 to £6000. However, if you’re on a tight budget and looking for the cheapest possible option, you’ll get a felt flat roof only on a garage at about £1000 to £1500. Meanwhile if you want to replace the entire slate tiles of a large family home, the cost can jump up to a range of £11000 to £13000.

Other factors that plays a key role in the determination of a new flat roof’s cost includes the location, labour as well as materials. For instance, a new flat roof price is likely to be higher in London and the south east than the other regions of the country. Also, labour may cost you around £150 to £250 per worker on a daily basis.

How to build a roof?

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.
