Flat Roof Repair
Flat roofs are extremely popular if you are after that modern look and feel for your home or commercial building. They are cheaper and require less material when installing compared to pitch roofs.
Nowadays, it is common to find flat roofs on house extensions, garage extensions, public and commercial buildings. While easy to install with little maintenance requirement, they are not as durable as pitched roofs.
How long is a flat roof guaranteed to last?
Flat roofs should last between 10 and 15 years while Pitched roofs last much longer. Most flat roofs are made from felt or asphalt.
What is the best covering for flat roof?
Common flat roof types include EPDM [Ethylene Propylene Diene Monomer], Asphalt, GRP[Glass Reinforced Plastic], Single Pl, Tiles and others.
When thinking of the best covering you will consider the lifespan, the price and the ease of maintenance.
EPDM is considered the best covering. The trims at the edges give a smooth and clean finish while waterproofing the flat roof. It is extremely light weight, resilient and elastic.
They are reasonably priced compared to other coverings and easy to install. Some EDPM roofs can last up to 50 years if well maintained.
5 Common Flat Roof Repair problems and their solutions
Whatever type of flat roof you may, if there are problems then flat roof repair is essential.
Problem: Cracking at the joints or corners as flat roofs tends to have more pressure exerted on them
Solution: Call a professional plumber as a crack in the roof is a sign that your roof has structurally issues and needs to be replaced. Your home is exposed to precipitation.
Problem: Ponds of water which means the water is not running off the roof into the gutters

Problem: Missing roof nails which may result from extreme weather or rusted nails. This could lead to leaks or moisture getting into the property.
