Two Ply Roofing Systems

Two ply roofing systems are systems that use two layers of a modified bitumen membrane to protect your building. They are generally secured to a protection board that is on top of the deck. 

The revolution in two ply systems now is the self adhering membrane. It allows installers to use limited heat in order to adhere the roofing products. This adds extra protection in high risk areas such as walls and doorways. 

They offer two ply systems for all different types of decks. For example, on concrete decks, or old wooden structures, you can ‘mop’ or use hot asphalt to adhere the base layer to the deck.  You can then apply a torch applied cap sheet (top layer).

Thus reducing the weight of the roof versus standard asphalt 4 ply systems and allowing for potentially easier repairs and replacements in the future. 

Four Ply Roofing Systems

Four ply roofing systems consist of four layers of felt paper, with each layer sealed using hot asphalt. They are run continuously in an overlapping manner. They are then covered with gravel to reflect the sun and prevent deterioration.

Frequently Asked Questions

There are circumstances that necessitate a roof to be repaired instead of being replaced. Repairing your roof instead of having it replaced not only saves you money but also enables you to conserve the environment by preventing old shingles from being dumped in landfills. If your roof is damaged but most of it is in good shape, you can repair it. 

The cost of redoing a roof is usually dependent on several factors including the type of roofing material or the size of the house. You should expect to may more for labor if your roof is high, steep and difficult to access. 

The recommended replacement schedule for replacing your roof is dependent on the type of material used on the roof. The recommended period are:  

 
 

  • Composition Shingles: 12-20 years 
  • Asphalt Shingles: 20-50 years 
  • Cedar Shingles: 20-25 years 
  • Single Ply: 10-20 years 
  • Flat Roofs: 15-30 years 

You should however consult a roofing contractor to conduct a roof inspection every year to determine whether it’s necessary to conduct replacement. 

Failing to replace your roof when necessary or delaying repair has both short-term and long-term effects. Short-term effects include an increase in the damage and water leaks. Long-term effects include structural damage and collapse, health risks, mold, and a decrease in the value of your property. You should therefore replace your roof immediately when replacement is the relevant option. 

We work in all seasons, it’s important to use the proper techniques in each season. We are certified and understand the weather, ensuring your property stays protected during replacement.
