"The work progressed on time by two excellent associates who were very capable in painting, but also in hanging patio doors. Their painting job was done very meticulously and the house looks clean and great! Giorgio also arranged for a plumbing contractor to replace leaky faucets to facilitate power-washing the walls outsi before painting. I feel that I got good value for the money."

"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."

"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."

FAQs for roofing installation & roof repair projects in Gaithersburg, MD
To determine the number of trusses you need, measure the full length of the roof ridge, convert that length to inches, and divide by 24 (the standard on-center spacing). Always round up to give the structure full support and add a few extras for overhangs or complex rooflines. This approach keeps your roof strong and code-compliant.
Start by measuring the span—the full width of the roof’s underside—then note the pitch, or how many inches the roof rises for every 12-inch run. Accurate span and pitch numbers help your supplier size each truss correctly, saving lumber and ensuring the roof performs as it should. Your roofing pro will be able to provide accurate measurements for you.
A three-person crew with the right lifting equipment can set a full set of trusses in a single day. Complex roof shapes or limited crane access can stretch that timeline, so talk with your roofer about the schedule and whether you’ll need to stay elsewhere during installation. Careful planning keeps the job safe and on target.
Trusses are prefabricated off-site, arrive ready to lift into place, and install faster and more consistently than site-built rafters. Rafters are custom-cut on-site by skilled carpenters, so they take longer and cost more in labor. Knowing the trade-offs—speed and uniformity versus on-site customization—helps you pick the best framing method for your roof.
If you’re not a licensed roofer, hire a pro. Installing trusses requires heavy equipment, safety gear, and code knowledge that most DIYers lack. While doing it yourself might trim labor costs, one mis-set truss can lead to expensive repairs or voided warranties. A certified contractor installs trusses quickly, follows code, and protects your home’s value.
