"They did a fantastic job building the deck I've always wanted. I told them what I needed, and they completed the project perfectly, even in the rain! I would hire them again in a heartbeat. Very professional and personal at the same time. Woo-Hoo!!!"

Choosing the right Home Inspector can be difficult. Unlike most professionals, you probably will not get to meet me until after you hire me. Furthermore, different inspectors have varying qualifications, equipment, experience, reporting methods and yes, different pricing. All of our inspectors hold Associats Degrees in Building Inspection Technology which required classes in Building Codes, Electrical Codes, Mechanical Codes, Plumbing Codes, Engineering Classes, Plan Review Classes and technical Report writing classes. All new employeees go through an extensive consistetency training program before going to work for us, so you always get the same highly efficient, educated and friendly staff who understand the key diffrnece between a minor defect and a serious structural concern. We don’t write books we write quality easy to read reports. One thing for sure is that a home inspection requires work, a lot of work. Ultimately a thorough inspection depends heavily on the individual inspector’s own effort. If you honor us by permitting us to inspect your new home, I guarantee we will give you our very best effort. This we promise you. Anything less and you can call us below 24 hours a day 7 days a week. Jack Applegate, CBO 503-812-9399 inspbuild@hotmail.com Brandon Zipser 503-931-6272 bzipser@hotmail.com

FAQs for addition to existing structure building service projects in Astoria, 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.
