How To Clean Moss Off Roof?

Although moss attack on your roof is a less common occurrence, but when they occur they can be very harmful to your asphalt shingles if not attended to. Generally, moss are commonly found in damp environments such as the North slopes, overhanging treses or overhanging regions of the roof which causes shade which enables moisture to be stagnant and moss to develop. If you observe a green fuzzy stuff appearing on your roof, that’s likely to be moss.

The same way algae navigated its way to your roof as they can be airborne and travel via wind, squirrels, birds or other little flying or climbing animals, moss also gets carried similarly. One moss finds its way up your roof, they’ll find spaces between the shingles where they’ll form thick spongy moss which can be difficult to clean off if you don’t know the best way to go about it.

If you’re not a competent DIYer or confident enough to carry out this task, we’d strongly recommend you hire the services of a professional who can guarantee the best results effortlessly.

The best way to go about the cleaning task for both your roof and environment is to incorporate a product called Spray and Forget or Wet and Forget. You can get these at most local hardware stores. Simply put the product into a hose end sprayer and can be applied from the ladder at the edge of the gutter or even from the ground. This method may take a up to 6 months before you’ll start seeing the results but it happens to be the safest. Another method that can be used is bleach and water which is very aggressive but provides a quicker result. However, this is best done by a professional to avoid seriously damaging your roof.

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.

Ponding is where you see pools of water appearing on your flat roof. Unless your roof is leaking or showing other signs of damage, you don’t need to replace it. When you do have your flat roof replaced, tell the contractor so they can find out the cause of the ponding.

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.

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.

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 flat roof depends on the type of flat roof you have. We’ll talk about how to repair felt, asphalt, fibreglass and EDPM flat roofs yourself. But ultimately if you want the best finish, it’s best to ask a professional to repair your flat roof for you. Repairing a flat roof Whether you’ve got an old pour-and-roll type felt roof or a newer torch-on felt flat roof, you can get cracks, lifting around joints, leaks or dips. As a temporary measure, you can buy a special paint that you paint over cracks. For a more permanent repair, you can add a patch of torched-on felt or add a layer on top. Asphalt flat roof repair As your asphalt flat roof gets older, you may notice blisters, cracks or shrinkage and sagging around flashings. Again, you can use a paint on fix from a tin as a temporary repair, or add heat-applied flashing tape around flashing. For a more permanent fix you can use a liquid system, but many are only available to the trade market. You can also add a patch of torched-on roofing felt over a crack. How to repair a fibreglass (GRP) flat roof Fibreglass flat roofs are usually excellent, but problems can involve leaking flashing and cracks near upstands, trims or board joints. You can add acrylic sealant to cracks or holes for a good DIY repair, but a flashing problem is more difficult to fix. You’ll need to clean and sand the affected area of flashing, then laminate a 600g chopped strand mat into place, cure it and add a topcoat colour to match the roof. That sounds like a job better left to a specialist. EDPM rubber flat roof repair Rubber roofs often suffer from shrinkage when mechanical fixings haven’t been used near upstands, flashing leaks or holes or cuts. If you’ve got a small tear that you want to repair, you can add some lap sealant to the area – but use it sparingly. For a more permanent repair to flashing, buy some self-adhesive flashing that will mould into shape easily. Clean the area you want to repair, add EDPM primer, then stick the patch of flashing on from the centre outwards with a hard roller. You can add lap sealant around the edges if you want more protection from water.

It depends on the material you use, but if your flat roof is installed correctly it should last for at least 10 years, and at least 20 if a material other than felt is used. Always question a roofing company when they quote to find out what materials they use and what guarantee's they offer.
