This may not seem like a problem yet!

As dependable roofers Liverpool we’re aware that if your roof has any leaks or is potentially vulnerable to weather you’ll soon find out.

What To Look For…

Stains on interior ceilings and walls – This can be caused by inadequate or faulty shingle under-layment allowing leakage. It may also be a sign of inadequate ventilation.

Missing cracked or curling shingles – This may be caused by low grade shingles that have been previously installed or simply, shingles that have exceeded their expected lifespan.

Roof Shingle Deterioration, Cracking, and Cupping – This could be caused by a variety or factors but is most likely due to a build up of heat due to poor attic ventilation.

Peeling, Bubbling, or Blistering Exterior Paint – The possible cause for this could be poor attic ventilation trapping moisture in the house.

Dark, “Dirty-Looking” Areas on Your Roof – Very common and can will be caused by environmental pollutants; lichen, algae, fungus or other environmental growth.

This blog was written to highlight the importance of visual checks and the need for a little roofing maintenance now and then. We’ve always been huge advocates of spending a little now so that you don’t have to spend a fortune in the future. So have a look as getting your roof repaired at a greater cost later, isn’t what any of us really want.

Do You Have Suspicious Stains On Your Ceiling?

Do you have any of the following Issues?

Stains on your ceiling. Water dripping from a recessed light fixture. Your chimney has wet masonry. A stream of water is running down your wall or dripping from a window well.

If any of these events are happening in your home you must have a roof leak, right? An appointment with a  Liverpool roofer is made. He checks the roof and tells you that some patch work will remedy the situation. The work is done, the roofer is paid but you have the same problem the next time there is a rain storm.

That’s not how we work!

What happened? There are a number of problems other than those associated with your roof that can cause moisture to enter your home.

Leakage can occur when wood or vinyl siding has been damaged, has worn out or was improperly installed. Wind driven rain can force water past the siding where it gets behind the flashing and into the roof system.

Masonry wall or chimney leaks can occur when these components deteriorate due to long term exposure the weather. The mortar can break loose from the bricks or even fall out allowing moisture to be forced into the structure where it runs down and can show up inside the home. Concrete block walls can be come porous and absorb water. These conditions can show up much earlier if the masonry work was not done correctly.

Mechanical intrusion is another source of leaks. Holes in rusted vent pipes can allow water access.

Satellite dishes, antennas, lightning rod systems or Christmas decorations with fasteners that pierce the roof can leak if not sealed properly. You may even need some replacement Guttering Liverpool?

Many homes have flat roof sections. If you have an HVAC unit on a flat section of your roof, leaky duct work can allow moisture to enter the home.

Our roof repairs Liverpool based company have also encountered some apparent roof leaks that don’t even originate at the roof level! We have found that second story windows with caulking that has deteriorated or frames that have split open can produce roof leaks on the first floor.

There have been several instances where a vent pipe installed thru a wall on an upper floor has admitted water and produced a leak condition on a lower floor. We have responded to leak calls that have been broken water pipes, leaking bathtubs and even dripping HVAC units located in attics!

The first call of action is to contact a roofer and let them detect your problems as they’ve seen it all before

Checking The Condition Of Your Roof

A visual inspection can really help to understand you roofing problems. Have a look over this quick guide in what to look for…

Start Inside

Roofing companies Liverpool will tell you that if the inside of your roof in unlined, you can check for cracks. Any daylight that is showing indicates that those areas will need a closer inspection. Check all the timbers to see if they’re wet or if they have water stains. If you find a stain, it would be helpful to try and trace its source. Obviously after or during a heavy shower is the best time as it’ll be easier to trace. All tiles deteriorate with age so keep a look our for cracks.

Ground Level Checks

Look for colour changes, they could indicate a tile that is newly exposed. If you feel you might need roof repairs Liverpool, this check should easily help you spot slipped tiles from a ground vantage point. Look along the ride on the skyline for gaps and the flashing around the chimney stacks. Fallen pieces of mortar on the floor or gutters also requires closer inspection.

Roof Level

We wouldn’t recommend any of our readers to get on the roof for inspection. Firstly you’d need the right ladders, including a roof ladder, that would help protect the roof from damaging slates.

It’s All About The Weather

If you’ve been reading the weather forecasts, we’re in for heavy rain, flash floods and thunderstorms.  We’ve been told that this assault on Liverpool is the result of the jet stream, and a series of low pressure areas.

Weather like this causes havoc not just for roofing companies Liverpool but in all over the country. We’ll undoubtedly loose more than a couple of roofs and probably as is always the case people will end up getting hurt. Forecasts are predicting more rain with week and hopes from summer sizzler as we had a few days in April.

The technical bit

“Waves” in the jet stream which moves weather systems across Britain mean areas of low pressure have lasted longer and created far more rain than normal, explained the jet stream usually pulls weather systems along but because it was not sitting straight, it had been holding the low pressure in place.

Rain is produced when low atmospheric pressure rises and gathers and as various weather systems have been moving across the country in the past few weeks, it can happen quickly. Being involved with roof repairs Liverpool, we know gaps in this weather system will occur, but contact us and we’ll be able to help get you back on your feet should any leaks or blow offs happen.

In a side note, today’s flooding had been caused by persistent, heavy rain in comparison to last week’s mini storms, which were more isolated and only lasted a couple of hours.

Blow-offs, tenting, reduced wind uplift resistance, and billowing

Blow-offs, tenting, reduced wind uplift resistance, and billowing

Here at Roofing in Liverpool you would be naive to think that leaks are the only problem that can result from flashing that is badly installed.

Open seams and laps that can on some occasions cause your titles or even your entire roof to blow off can be a consequence of poor work on hot bituminous roofs.

You may have poor puncture resistance, and gravel embedment issues cause by an inadequate amount of fasteners in the base sheet during application of the roofs

Here is the technical bit – ‘Wind uplift resistance can be reduced greatly if seams are not cured adequately on cold-applied systems’. This basically means that seams made with cold adhesives do not have good integrity until the adhesive has cured. If they aren’t properly cured and then they get exposed to the elements (Wind and rain), then moisture will certainly get in and the whole roof system will be damaged as membrane becomes ineffective.

As Liverpool Roofing, we know a roofer must adhere to the substrate in single-ply roofs or you’ll seriously risk a roof blow off or at the minimum some billowing.

A single-ply roofing membranes do a little more to hold things in place, but as with everything an improper job will end up with tenting,flashing problems and membrane damage

Roof Repairs Liverpool For Leaks And Moisture

Roof Leaks And Moisture

When we are roofing in Liverpool, we see a lot of problems that have resulted in leaks and moisture damage.

Obvious or unforeseen, roof problems are always a pain and can be costly and will result in you needing our roof repairs Liverpool service. With every single roof and no matter which kind‚ if you have roof leaks, then unless checked or repaired as soon as you notice them you’ll have a big issue down the line.

A leak will occur for a number of reasons. Flashing details in built up roofs can experience leaks because they aren’t fastened properly during their installation.

The problems an owner is typically going to have with a built up roof will be that in the majority of cases that the leaks occurs because of the flashing details – meaning the membrane is interrupted or terminated. Additionally, hot bituminous and torch-applied modified bitumen roofs may experience leaks when a proper moisture barrier is not installed underneath a coping cap on parapet walls.

Any defective installation of the flashing will be a source of leaks at some point, especially with torch applied modified bitumen roofs. Moisture infiltration caused by poor head laps and backwater laps will also cause you a lot of problems down the line. If water gets underneath the roof membrane because the field of roof is installed so that water flows against the lap, causing blisters and leaks. Therefore the roof will not be fit for purpose

A cold-applied modified bitumen’s, the storage of the materials can result in moisture infiltration if it was improperly stored. This will then be built into the roofing system, not using the correct amount of adhesive will also result in poor lamination and leakage.

Leaks can result when single-ply membrane roofs are installed with poor seams.
