When it comes to roofing, there are many different styles, methods of fitting and combinations of materials that can be used. So there might be some things that even the most experienced roofer has not come across, or didn’t know about. So here’s just a few interesting “did you know’s”.
Did You Know?
Double Layering Doesn’t Increase Protection – many people believe that if your roof is falling into disrepair, or is just simply starting to look a bit tatty, that you can simply add another layer of roofing on top of the existing roof, increasing its coverage and protection for your home. Sadly there are a number of reasons as to why this isn’t always the best idea. This can lead to increased weight on your roofing support, which, over time, or in bad weather, can increase the pressure and likelihood of collapse or substantial damage. Double layering can also hide existing damage which would need addressing rather than covering.
Roofs Breathe – as we all know roofs are there to help protect the contents of our homes from the elements of the great outdoors, with includes rain. It might be an interesting notion that your roof actually breathes, meaning that we need to allow space for air to enter into your roof. Roof ventilation allows warm moist air to escape, and be replaced with cooler dry air. Without this ventilation, condensation can build up in your loft space and cause dampness, mould and damage to your walls, insulation and wood beams.
Flat Roofs Arent Flat – on the contrary to the name, flat roofs aren’t actually completely flat, so don’t go getting your spirit level out. In order to allow water to drain from the roof, rather than sitting in little puddles and causing you more issues, even flat roofs slope off to an angle. As a minimum, this angle is usually ¼ of an inch per foot.
Water Can Travel – If you find a leak coming from your roof, don’t expect the source of the leak to be directly above where it is appearing. Water can actually travel as far as 20 feet before breaking through. So make sure you inspect your entire roof, as the lace you thought was the issue, may just be a red herring.
Long Life Spans – while many people believe that the average life of a roof is around 25 years. It can actually be double this. Good quality roofs can last up to 50 years providing that they are regularly inspected and any minor issues are repaired as soon as they are discovered. The lifespan drastically decreases if small issues aren’t resolved and left to cause more damage.
