"Unprofessional visit. Showed up unannounced and we only knew they were there because one person stood 10 feet from our porch staring at us in through our living room window. My wife spent 10 minutes talking to them, they stated they had no business cards, they only had an appointment card but didn't present it. Honestly when you show up at someone's house you need some sort of identifier if your walking door to door in casual clothes. After the uncomfortable dead stare through the windows my wife and i have decided to post a No Solicitors sign. They didn't take no for an answer at first, pushing with more questions to circumvent the no she gave, as well as interrupted our dinner, as they showed up right at 6pm."

"Vanguard Roofing was our 2nd choice, so there was no work done. The issue was on our end, not Vanguards, as to why we chose someone else. I would have no problem recommending them to others, which I already have done. They were very helpful in understanding and explaining how a high wind-resistance roof is installed. The only reason for 4 stars and not 5 is because Vanguard did not install the roof."

"They came and looked at our roof but unfortunately they do not understand what an estimate means. The customer is expecting to pay a certain price for certain repairs. Nothing more, nothing less. This company likes to include open ended clauses in the contract which would allow them to charge more as they see fit when they get the job and the competition with other providers is over. This is just unacceptable. Nobody hires a company without a clear budget unless they want trouble."

"This company is very shady and unethical. We selected them because of the price. It was substantially lower than other quotes received. The reason it was lower was because it wasn't accurate. With the dumpster in our yard, and the roofing materials delivered only then did they "discover" we also needed all new planking. We were prepared and budgeted for a $21,300 project. Suddenly we needed to come up with an additional $8,500 for the plywood. This was part of all the other roofer's quotes. When I voiced that I wanted to use another company they told me I signed a contract and they planned to enforce it. If I broke the contract I would have to give them 1/3. I had no choice but to cave. When I pressed on why this wasn't discovered until they started- they had no response. I was stuck and was forced to proceed (or walk away from $7,100). BEWARE!!! 6/25/2025"

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.
