The A/R Roofing team is more than qualified to complete your residential and commercial roofing and exterior remodeling projects. With more than two decades of experience in residential and commercial exterior work, we have established a reputation for doing honest, quality work at a great price. We know it's pretty easy to find crews to work on the exterior of your home or business, but you must be careful who you trust. Smaller crews are not always licensed and insured, so hiring them is risky. We want the best for you, and that's why all our crews are licensed and insured to protect you or your business in the event of an accident. We want to give you the best and be able to guarantee the work we do on your property; that's why use only top-notch, nationally-respected manufacturers to source materials for our jobs.

"Outstanding roofing job. high quality in a timely manner. They left no room for improvement. This homeowner couldn't be happier."

I am a Journeyman Union Carpenter by trade but after 15 years left it to pursue other things. I have had rental properties and done hundreds of property rehabs and remodels over the years. I have a working knowledge of plumbing and electrical and I take pride in my work. I also rehab and refinish antique wood furniture and build custom furniture out of old wood and recycled materials. No job is too small and I enjoy meeting all the people that this kind of work leads me too.

Window Door Contractors questions, answered by experts

Sometimes, these two terms are used interchangeably, but they are separate parts of a door, and each serves a different function. The sill helps ensure the doorframe is secure, and the threshold helps protect the sill and direct water away from the door to prevent leaks.

When hanging a door frame, it’s recommended that you use screws, not nails. Screws are more secure, easier to tighten, and easier to remove if you need to adjust the frame. On average, the cost to replace a door frame is about $400, but you can save on labor costs if you’re confident in your ability to DIY the project. 

Fire doors are more expensive than your run-of-the-mill residential composite door because of additional materials and expanding sealants that help the door slow down or even prevent the spread of temperatures over 1,000 degrees. If you have homeowners insurance, talk to your company and see if installing fire doors can lower your premiums, especially if you can install steel doors.

First, make sure the couch and door measurements are compatible. Removing the interior door increases the opening if it's a close fit. You may need to turn the couch on its side or move it in separate pieces, if possible. Your best bet is to use furniture sliders to help you slide your couch through a doorway.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.
