I got my house roof done by RoofPro and I was in the fence about my garage roof getting done as well. David from RoofPro has been such a great person to work with on this project, I didn’t hesitate to call him for my second. It’s nerve racking having projects like this and the whole entire process was made easy because of him and his companies efforts. Definitely the best quality and the best service I have had. My roof is beautiful! Highly recommend!! ??????

I have been a customer of RoofPro for ten years. They have been terrific: responsive, expert and prompt. They did an excellent job of replacing our very old gutter.

RoofPro replaced our aging asphalt shingle roof with Owens Corning shingles, including a 50 year manufacturer warranty and 25 year workmanship warranty. The staff at RoofPro were prompt, professional and pleasant to work with throughout the process.

How It Works

In Maryland, where temperatures can vary greatly between seasons, proper attic insulation can help keep your home warm in the winter and cool in the summer. The process of insulating an attic involves several steps: 

  • Determine the amount of insulation needed. 
  • Close off any areas that will allow air to seem through.
  • Make sure baffles are in place for proper ventilation.
  • Install insulation.
  • Install extra protection at the attic door.

Keep in mind that once you have installed insulation in your attic, if you place anything on top of the insulation that compresses it, the insulation will lose its R-value. 


Have questions?

We offer free consultations to discuss any questions you have related to your attic insulation. We know that many homeowners in Maryland have been upgrading their attic insulation to protect their home and become more energy efficient. Contact us today, we’d be happy to meet.

Check The Depth

If you already have insulation in your attic, you can most likely keep what you have and add to it. There is a recommended depth for building code and also another for Energy Star rating.

Protecting Your Insulation

Once you put insulation in your attic, if you cover it with wood or boxes for the sake of storage, you will end up losing the R-value of the insulation. If you take R-49 and compact it, the R-value will decrease.

The best type of insulation for an attic will depend on your specific needs and budget. Common options include fiberglass, cellulose, and spray foam. Each material has its own set of pros and cons, so it’s important to research and compare before making a decision.

The recommended level of insulation for attics is R-38 to R-60, but the exact amount will depend on your location, climate, and current insulation levels.

It depends on the condition of the existing insulation. If it’s in good condition, it can be left in place and additional insulation can be added on top. However, if the insulation is damaged, contaminated or has an inadequate R-value, it should be removed before adding new insulation.
