"I would not hesitate to recommend - responsive, great communication, reasonable pricing. We had a disastrous roof flooding experience from a flat roofed dormer and needed it fixed quickly. As Roberto worked on the dormers he found significant water damage below the shingles, documenting it with photos for us. Although it cost more than the original estimate to replace the flat plywood sheaths and wood fascia, it was still reasonable and the work done was thorough and looks great. "

Transform your space with Washingtonian Companies, your interior/exterior design-build team. Whether it's roofing, windows, siding, decks, kitchens, bathrooms, or additions, we are your trusted partner to bring your vision to life and help personalize your surroundings.

"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."

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."

FAQs for natural slate roofing repair projects in Gaithersburg, MD

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
