"Extremely disappointed with this company. They do not stand by their guarantees. Did install shower in one day. Was not provided with the shower head I ordered. Calking and trim work was very sloppy. Went through the shower wall into my bedroom, did sparkle wall and left it. Shower doors have leaked and was finally told six months later that there is nothing they can do to correct the issue. Originally quoted $24,000.00 for the walk on shower, eventually agreed to $11,500.00. Completely dissatisfied with my shower. Once they get their payment, they are done."

"Initially,contractor presented himself as respectful and trustworthy and assuring me of wanting to know "exactly what u are getting" when referring to windows and building materials. Major break in communication once contract was signed...as well as ethics. Materials were ordered(customer never notified) and delivered to job site.Materials were never checked for accuracy as contractor was not there when they were delivered.ENTIRE job delivery of materials was left in soaking rains,uncovered,untarped until homeowner got home from work later that day.Contractor was called and didnt seem to care.Was questioned on damage to boards left in rain and that they shouldnt be used on roof.He used them anyway.Interior damage was done in multiple areas ( walls and ceiling) that were not part of remodel contract.Contractor became very defensive when asked to fix.Slamming doors..Allowed house door to be open as they went to lunch.Never closed. Ordered wrong size windows and installed without homeowners ok.Never asked. Cut drywall in major miscalculations and filled in with spackle.Lines up multiple projects both professional and personal life then becomes overwhelmed and agitated with paying customer who wants their home project completed per contract. Was given extensive courtesy as well as time to complete. Did not use plastic or any covering to keep project dust from entering other rooms.Attempted to use homeowners shop vac for job clean up instead of the shop vac used for job site clean up. Will never refer this contractor to anyone that wants quality or someone who is trustworthy."

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.
