Do Flat Roofs Cause Problems

A flat roof should actually have a slight gradient to allow rainwater to run off and have a decking of marine or WBP plywood. If your flat roof hasnt been fitted properly, it can lead to a variety of problems which occur over time such as water ingress, condensation, water pooling, cracking and thermal movement.

Tips For Applying Roof Sealants

Applying a coating is not anything new. There is no need to discover the wheel again, so follow these helpful tips to save time, money, and efforts.

  • Make sure to pick the right coating. Determine what matters to you the most in your roofs maintenance and what you need the sealant for. This will help you narrow down your search, as well as avoid wasting your money on rip-offs.
  • Prepare the work surface. Its highly inadvisable to apply any product without getting rid of the trash, leaves, and dust that like to collect on the roof. Otherwise, your product might just not adhere well.
  • Fix the surface up. If you have any major damages, like cracks, scuffs, holes in the roof, stitch them up. This will improve the integrity of your membrane, leaving fewer weak spots.
  • Look up. You wouldnt like to start applying the solution without making sure that it wont rain. Though your coating can be water-resilient, its no use when its still wet.
  • Use a variety of tools. Dont limit yourself to using only a roller since there is a whole wide range of utilities that can facilitate the application. Yes, it will be messier should you utilize many tools, but you will save time and effort.
  • Double the effect. Though a product may guarantee a perfect membrane after the first application, its better to apply another layer on top. This way, your coating can have double the effect you expect of it, thus being more durable and reliable.
