"Not only did Derrick and his crew completely redo the foundation of our house plus install flooring, but they were timely polite communicative easy to work with and did an excellent job. I can’t say enough good things about them. They took over a project in the middle of it and coordinated with us as it’s our vacation home and we don’t live in the same town. I can’t begin to tell you how much we appreciate them and will be using them in the future!!!"

"West Lake Construction removed existing roofing shingles on my large house ( 63 squares!) and installed architectural composition shingles. They had to replace ten sheets of new CDX plywood. The boss was Tyler Weston, who knows his roofing. He was always nice to work with. His crew was hard-working and knowledgeable. He kept on budget. They cleaned up really well. I highly recommend this company."

"Only thing they did themselves was the patio ceiling & French drain for my project. Acted as hiring contractor for all the other work. Overall project was a success, but I didn't appreciate how the lead crewman/ owner spoke to his employee. Subcontractors that were hired were excellent."

"NW Builders & Renovation inc and Eric, the project manager, did a great job explaining all the roofing materials and steps to us. They were able to pull in the installation date and complete all the roofing work in four days, just before the big rain arrived."

"After getting quotes, hiring a company & later firing that company to build us a deck under our deck, we were really defeated thinking our very sloped useless backyard would really ever have usable space. I found a recommendation for Mike at MG Exteriors on Happy Valley Chit Chat and gave them a call. He came out quickly for my quote (not a salesperson but the owner) and quoted us on the spot. He also looked at my existing deck & recommended we protect that one pre-construction of the new one (it was only 2 yrs old but already looked sad. We received a fair quote (less than the 'fired' company) and they were able to start us quicker due to a cancellation. Construction was in time, they were punctual, clean and ALWAYS available for questions. Highly recommend!!"

The rating is bogus as it is required to be able to submit.

"Guys from Pacific Floors installed brand new engineered hardwood and baseboards in my three-bedroom house. They finished on schedule and did a beautiful job; my house looks like new now. I already scheduled this company to do a full upgrade for my bathroom's tile."

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.
