For the last 33 years I’ve been doing just that . I guess you can say “ I’m living my dream “. I do my best to listen to my clients and help them with the vision they gave for their. Communication from start to finish.

"Awhile back I decided it was time to replace my old, crumbling shed. After doing a search on Angie’s List, I hired Gryphon Construction because they had good reviews. The process worked, and I must say that I’m super happy with the results I got. Not only were Akeem and company great to work with, they did an excellent job, and and I’m extremely happy with my new shed. (The only reason I’m not calling it “shop” is because I didn’t have power installed). It’s solid, has a locking door, as well as a window, and looks more like a tiny house than the shed that proceeded it. And while they were here, I also had them install a new track for a broken pocket door, which involved removing some dry wall to get at the work-out track. They did a great job on that, too, and I’m very happy with the remodel. I found them to be pleasant to do business with, as well as very conscientious, timely, and they have a strong sense of craftsmanship, which, after all, is what we all want in a good contractor. I highly recommend them!"

FAQs for addition to existing structure building service projects in Gresham, OR

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
