We had a leak in one of our bathroom ventilation and contacted our neighbor Deder to get it looked at. Not only did he repaired the leak from but also gave us an honest assessment of what we needed to do in a near future for our entire roof for free. He is very professional and so easy to talk to. Its plus for us to have him as our neighbor as well. He has my highest recommendation for any roof repairs and minor repairs inside and outside any home. Thank you again Deder.
Sincerely,
Al and Jen (Your Neighbor)

Very clear concise explanation and planning. The workmanship is very good. His team stayed late to get the job done on a very tight schedule.
Bottom line in the future if I need a job done absolutely!! I would call again.

We are new to the Lake Stevens area and Acquired a home 20+ years old with original roofing. and inadequate venting.
Deter came as a referral and was prompt to answer my request for consultation. He proceeded to give me a complete analysis of my roof and attic space at no charge.
After deliberation and seeking other bids for venting we decided to go ahead with Deter.
He was very reasonable in pricing, explained thoroughly the process of adding venting and went the extra mile by answering all my questions completely. He made sure the job was done right in terms of best materials and practices.
In addition I found him to be friendly, courteous and professional in all respects.
Do not hesitate to give him a call if your interested in roofing, or general remodeling.

It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.
The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.
To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
