Why choose ROI Construction? Our Gold Standard guarantee is 100% customer satisfaction, 100% of the time! - It's that simple. No need to keep looking for “Contractor near me,” we are the top local Maryland and DC family owned Exterior company (est. 1974) that delivers the best results and a positive return on investment in the area! ROI also does a final walkthrough of every-single-job to ensure that we deliver a superior finished product for every ROI customer!
"While I appreciate the company's attempt to rectify initial issues, our overall experience with this solar installation was unfortunately very unprofessional. The initial installation team demonstrated a lack of respect for our property, damaging plants, leaving debris (including an orange cone), and inappropriately using our private bathroom despite a readily available public restroom on the premises. Following my initial negative review, the company offered a Home Depot gift card as compensation, which wasn't particularly useful to us. They also offered to address some unrelated roof repairs they noticed, but I questioned why these weren't addressed during the original solar installation. Scheduling follow-up work proved equally frustrating. An appointment was scheduled for Wednesday, but the crew arrived a day early on Tuesday without prior communication. While I appreciated them attempting to complete the work ahead of schedule, they left the roof partially finished overnight, exposed to potential weather damage. Furthermore, the crew damaged another plant box during the Tuesday work and continued noisy work – including banging on the roof – until 8:30 PM on Wednesday, violating DC noise ordinances that typically require work to conclude by 7:30 PM. This put us at risk of a city violation. Throughout the entire process, communication was poor and the lack of consideration for our property and local regulations was deeply concerning. While I appreciate the attempt to make things right, the experience was ultimately not ideal and left us feeling very dissatisfied."

"STAY AWAY!!!! This Company cancelled the initial estimate on me 3 times making me drive 90 minutes to the property each time. They finally showed and gave me the typical hard sell "if you sign the contract today..." They gave us a quote so far over market value we should have walked away. But we agreed because of the "70 year history in the industry" We thought we were buying a service from a company with integrity. They took an immediate $18K deposit on a $55K project. I know, shame on me for agreeing to such an amount. We knew we were over spending, but... One month later, they simply cancelled the contract without explanation and without any work on the project. This contract was binding on us but, in their words, was not binding on them because "there's a clause in the fine print that allows them to cancel" THEY STILL HAVE OUR MONEY and I STILL NEED A ROOF Stay away from this company. No integrity No responsibility Unreliable Over priced Will take your money and keep it"

Roof sealant applications FAQs
A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing.
You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.
A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
