If you have a flat roof on your home, you already know that it is a good covering. However, after time, even the best of roofs begins to show wear and tear. If you suspect that your roof is failing, you need to contact an expert who handles flat roof repairs and replacements.
For example, in order to check the condition of your roof, you need to inspect some key areas. Your roof probably needs replacement if you notice settlement cracks or stained or displaced flashing. You also should note an efflorescence on the wall. If you see this indicator, it may be a sign that leaks exist in the parapet or coping.
In addition, you may need to have your roof replaced if you notice discoloured or chipped paint or damp or stained walls. All these warning signs show that you have sustained some water damage. When you contact a company that handles flat roof services in Cornwall, inspectors will check under the roof’s deck.
Signs That a Replacement Is Needed
Signs that show a replacement is required include warped or rotted boards on a deck made of wood. If the deck is made of gypsum or concrete, stains or cracks will be noted as well as rust. The rust results from reinforcing rods in the concrete that are wet. A gypsum deck can spell form leakages. If the deck is made of metal, areas of rust will be displayed.
Has a Wood Board Sprung in the Deck?
A roof replacement should also be planned if a wood board has sprung in the wood deck. This is identified by a noted indentation on the roof’s surface, which is caused by a broken board. If the inspector observes that the roof gives under added weight, the roof needs to be replaced. Cracks in the roof’s membrane also signify a future replacement.
Look Carefully at the Drainage
Drainage is yet another consideration. If you notice a change in the slope of the roof or you see pools of standing water, you need to install a new roof. Blocked drains or guttering also denote that the roof may have leaks.
Checking the Copings
Copings should be inspected as well. The inspector will look for gaps, cracks, or damage to the joints. He or she will also inspect the flashings. He or she will look for flashing that is not turned up or that is torn, missing, or loose. Rust on the flashing also indicates that a roof is leaking.
Any roof should be inspected twice annually, especially after storms. When making inspections, any deterioration should be noted as well as vegetation growth or buildup of debris. Also, deck deflections should be noted as they sometimes indicate structural problems. In addition, ice formation on a roof can lead to membrane damage.
The inspector is always on the lookout for warping, splits, slivers, cupping, rot, or cracks. He or she also checks the roof for deteriorated felts, bare spots, or rupture. Any of the clues are big indicators that you need to go ahead and install a new roof.
