Roof System Components

All sloped roof systems have six basic components: 

  1. Roof covering:  Composite shingles, Concrete tile, Clay tile, slate or metal.
  2. Underlayment:  Synthetic, felt or rubberized asphalt underlayment protects the sheathing from weather.
  3. Sheathing:  Plywood boards or sheet material that are fastened to roof rafters to cover a house or building.
  4. Roof Structure:  Rafters and trusses constructed to support the sheathing.
  5. Flashing:  Metal or other nmaterial installed into a roof system’s various joints and valleys to prevent water seepage.
  6. Drainage: A roof system’s design features, such as shape, slope and layout that affect its ability to shed water.

Ventilation and Insulation

Proper ventilation is a critical factor in roof system durability. Without it, moisture and heat buildup in an attic area can cause sheathing and rafters to rot, insulation to lose its effectiveness and shingles to buckle. Our roofing team will ensure proper attic ventilation to help prevent these issues.

  • Enough open, vented spaces to allow air to pass in and out freely.
  • Different types of ventilation include low profile O’Haegan Vents, Dormer Vents, or Ridge Cap ventilation – our professionals will advise the best option for your roof.
  • A gap-free layer of insulation on the attic floor to protect the house below from heat gain or loss.

Feel confident knowing that Baker’s roofing team will happily cover roofing basics and roofing terminology to ensure you understand the process. We treat every project with the utmost care and attention to detail, and our commitment has made us a trusted residential roofing contractor. Have questions on your roofing project? Give us a call and we can schedule your roofing assessment.  

Need a new Roof? Consider Solar.

An average of 2.3 million single-family detached homes will require a roof replacement over the next decade.

However, if you also look at your energy bill every month and scratch your head as to why you pay so much, you are not alone. Combining your roof replacement needs with a new solar system can add up to some serious savings. For example, financing the cost of your new roof and a solar system could turn out to be the cost of your current electric bill.

  1. Combining Costs: Depending on the size and composition of your roof and other factors it will last anywhere from 20 to 50 years similar to the lifetime of the average solar system. Getting both services done at the same time saves you potentially thousands.
  2. Value: A report from Lawrence Berkeley National Laboratory found that solar panels are viewed as upgrades and home buyers across the country have been willing to pay a premium. Let your home stand out with solar against the competition.
  3. Long Term Savings: Don’t forget utility rates are going up. You may have been thinking about going solar in the future  and you need to get your roof done anyways. Taking advantage of the Tax Credit could give you an added financial bonus at tax season. While the energy you produce gives you added comfort that you are relying less on the energy grid.
