Critical Questions for Contractors to Ask when Choosing Appropriate Roof Waterproofing Systems

Julian Caldwell

For any commercial facility, the roof is arguably the most visible portion of the entire structure. Therefore, the roof is susceptible to fast deterioration which more often than not leads to leakage and moisture buildup. It is for this reason that roof repair should be treated with the seriousness it deserves to prevent leakages. As one of the most effective ways to repair leaking roofs, the benefits of waterproofing a roof is usually realised for years. Such longevity is, however, only possible if a contractor uses the right waterproofing method. This article highlights questions that a contractor should ask when preparing to waterproof a commercial facility.

How Much Moisture is Acceptable? -- Different commercial facilities have varying amounts of acceptable moisture levels. A contractor should, therefore, determine before deciding how watertight a roof should be. For instance, if a facility is used as a parking lot, then a little moisture from the roof is acceptable. It is because such spaces are often empty certain times of the day and no equipment can be affected by the humidity. However, if the facility houses critical establishments or businesses, such as hospitals, museums or offices, then the waterproof material used should be watertight. It will ensure that all areas stay completely dry, thereby eliminating interruptions as a result of damage caused by roof leaks.

Purpose of the Roof? -- In modern structures, the roof can double up as a relaxation spot or a garden. Therefore, it is essential for a contractor first to find out what the roof is primarily meant for. For example, if the roof performs the sole function of providing cover to the occupants, then the waterproofing material used should withstand weather elements. On the other hand, if the roof is used for some other purpose such that there is high foot traffic, then the waterproofing membrane should be durable enough to withstand not only weather elements but also the high foot traffic. If a contractor does not consider such aspects, then the waterproofing membrane will wear fast which will consequently call for frequent and costly repairs.

Condition of Roof Substrate? -- Different waterproofing techniques suit different roof substrates and their conditions. For instance, if a contractor is dealing with a high moisture roof substrate, then the best waterproofing system is an epoxy primer. It is because epoxy primer binds well on surfaces with high moisture content, providing a watertight sealant. On the other hand, if the roof substrate has low moisture content, then a polyurethane primer will work well. The primary objective of matching a roof substrate to an appropriate waterproofing system is to ensure adequate bonding.

Hi! My name is Robert. I live in Brisbane with my wife and our two kids. For many years, I have been saving up money so I could build our dream home. I first saw my dream home when I was aged 21. I was on a holiday to the USA and was staying with friends in California. While down on the beach one day, I spotted a lovely mansion house which was high up on the cliffs. I decided that one day, I would like a house like that. Last year, I instructed a team on house builders to begin construction of our new home and I couldn't be happier. I have learnt so much from the experience, I decided to start this blog.
