"We were 100% satisfied with Washingtonian and with their work building our addition and deck. Not only was the workmanship and quality of the construction outstanding, but they operated with honesty and integrity. Their goal was our satisfaction and building a quality addition and deck. They accomplished all three and were reliable, dependable and conscientious. At no time did we believe that they had over-committed or were unable to deliver on what they had promised. They never cut corners to rush to another job nor did I ever feel that they were not spending the necessary time to ensure that the work on our job was thorough and complete. Travis, Kris and their crew were 100% professional, communicative and transparent. We will be using Washingtonian again, without hesitation. Our experience was excellent and they did an awesome job."

"We were looking to increase our attic insulation and met The Home Doctor Company at the Capital Remodel and Garden Show in February 2025 as well as some other companies. We consulted with several companies and decided to go with The Hone Doctor for our attic insulation. The company rep, Chris Lear, was very good explaining what they would do and why our attic needed R-38 insulation. I knew we needed more but did not realize our attic was only R-13. I have worked with numerous contractors before on projects and felt this was a really good company plus they have great reviews. The installation of the attic insulation went very well. They do install siding as well but decided to put this project off for now. Would highly recommend this company."

"Spent ~$50,000 on a new roof with them. Thought everything went well. Years later discovered that they had not sealed the cricket on the chimney well enough. Discovered water coming in and eventually rotting the wallboard, studs, etc. Had to replace entire wall. Called them about the issue, they sent a rep. He said it was the chimney's fault, it was leaking. Not so, opened the wall and ceiling and had another roofer come spray water on the chimney, nothing, no leak. Then sprayed water on the cricket, water came in. Exterior Medics would not admit any fault. Had it repaired, no leak, no problem since then. Had recommended to a friend, never gain, he also had a bad experience. DO NOT USE IF YOU WANT QUALITY WORK AND A COMPANY HAT STANDS BEHIND THEIR WORK."

Three-tab shingles provide 15 to 30 years of service, with actual performance depending on installation quality, local weather patterns, and maintenance practices. Homes in regions with extreme temperature fluctuations or frequent storms may experience shorter lifespans, often closer to 15 to 20 years. Regular maintenance and prompt repairs can help maximize your roof's functional lifespan.
The cost difference stems primarily from material composition and manufacturing complexity. Three-tab shingles feature a single-layer design requiring less raw material than the multi-dimensional construction of architectural products. While this makes them more affordable initially, they offer less wind resistance and shorter warranty periods than their architectural counterparts.
Warning signals include curled or buckled shingles, bare spots where granules have disappeared, missing shingles, visible cracks, and granule accumulation in gutters. Inside your home, water stains on ceilings, light penetration through roof boards, or sagging sections indicate serious problems. Industry professionals recommend evaluation for replacement when roofs approach 20 years of age.
While technically possible in some situations, installing new shingles over existing ones is not recommended by roofing professionals. This approach adds considerable weight to your roof structure, prevents proper inspection of the underlying deck, and may create moisture issues. Many building codes limit homes to a maximum of two roofing layers, requiring complete removal before new installation if that limit has been reached.
Your local climate significantly impacts both installation requirements and long-term performance. Regions with severe weather conditions often require additional reinforcement measures that increase installation costs. Performance-wise, three-tab shingles have lower wind resistance ratings compared to premium options, making them less suitable for hurricane-prone regions. In hot climates, specialized reflective shingles may be recommended to improve energy efficiency.
