Many Ottawa residents were saddened to hear The Canada Science and Technology Museum would be closing its doors for the next two or three years. The reason behind the closure is a serious but avoidable issue – a mould infestation. Mould infestations are usually the direct result of excessive moisture. In the museum’s case, this moisture was a derivative of a faulty and leaky roof.
In Ottawa, roofing maintenance is of the upmost importance because our long and harsh winters bring with them wind, ice, snow and water – all elements that can be detrimental to both metal and asphalt roofing for several reasons, including the following:
1. We all know that melted snow equals water. In Ottawa, roofing sees lots of snow and therefore plenty of water. This is bad news for asphalt roofing. The absorbent nature of asphalt roofing means it is subject to rotting along with moss, mildew and/or algae growth. Water that seeps under asphalt roofing can also cause shingles to buckle and/or break.
2. Freezing and thawing can cause metal roofing to expand and contract, which can result in loose shingles if not installed properly. Loose shingles are more easily permeated by water, which can cause leakage.
It appears the museums roof fell victim to these elements and poor maintenance worsened the problem. After officials began repair on the now mould and asbestos ridden building, they found metal, cement and asphalt roofing patches. It is likely that these patches were used as a ‘quick fix’ and were simply no match for our Canadian weather. Now the museum’s roof is at risk of a collapse. In Ottawa, roofing on the museum will be paid much attention this winter and must be cleared to at least below ten inches.
Whether your home has metal or asphalt roofing, ensuring maintenance and taking precautionary measures are of the upmost importance. While the museum may present an extreme case, it is true that an unkempt roof can result in mould and asbestos, both of which can be extremely hazardous and in some cases, such as the museum, can render a building inhabitable. Although Iin Ottawa, roofing maintenance can often get overlooked, a well-maintained roof is really the basis to a well maintained home. This begins with properly installed shingles and continues with regular inspections and repair. Regular maintenance will help your roof perform its job – protecting your home and family.
