Ensuring Roof Longevity by Adequate Professional Waterproofing

The US receives rainfall both in winter and summer seasons. Hawaii is the wettest state with an average of 1618 mm of rain yearly. Other winter rainfall states include Washington, Mississippi, Alabama, and Louisiana. The states receiving summer rains include Iowa, West Virginia, Georgia, Florida, and North Carolina. It is important to adopt proper roof waterproofing methods to avoid damages.

Use of bitumen materials

  •  Roof waterproofing involves the overlay of a suitable bituminous material over the existing roof. Asphalt and Bitumen are materials that are composed of viscous organic liquids.
  • Besides the layering with the waterproof liquid, usuage of roofing felt is also a common method. The asphalt felt paper is basically a sheet of bitumen. Roof rolling is the process of attaching this felt sheet on the exisiting roof.
  • Many services also use modified bitumen wherein the manufacturer combines asphalt with sand, limestone, or polymers such as APP (Atactic Polypropylene).
  • Many advanced roofing services also develop their trademarked waterproofing substances. These solutions can be ideal, but the pros and cons of these methods need to be discussed with the roofers. Most of these advanced products work on the cold application method, thereby minimizing the health hazards from the toxic fumes of hot asphalt application.
  • Thermoplastic sheets reimposed with fiberglass also serve water resistance requirements effectively. Such materials have bright colors, making it easy for the roofer to apply it evenly on the surface.
  • Styrene Butadiene Styrene (SBS) is a special rubbed additive to infuse increased elasticity in the felt sheet.

The American Society for Testing Materials (ASTM) ascribes certain codes to certify the felt papers. Many conscious homeowners also look for Bitumen alternatives because it is an unsustainable crude oil product and is highly flammable. In addition, the application of hot Bitumen tar is highly hazardous for the roofers. You need to connect with a professional roofing service in your area to discuss the issues in detail.

Whenever you are in the process of selecting a waterproofing membrane for the roof, check certain vital parameters, such as:

  • The longevity: Find whether the roofer can deliver decades of warrantee on the waterproofing membrane.
  • High resistance: In a state like Hawaii, you need a solution that can resist water damage over a constant dampness. If you have a flat roof, find whether the material can withstand hydrostatic pressure.
  • Fungi resistance: The material should not be conducive for fungi and bacterial organisms.
  • Thickness and elasticity: The cost of the service often depends on the thickness of the membrane. Roof covers with high elasticity have been proven to be more effective than the usual solutions. 

Contact a professional service and choose a suitable provider depending on an evaluation of the traits mentioned above. Water damage weakens the roof over time; a timely investment on waterproofing can save you in the long run as it will help you avoid a complete overhaul.
