Alex and team did a great job with our roofrepair project. Before starting the job, Alex helped me with details of the issue, possible fixes and provided cost breakdown for each area. The whole process from scheduling to payment was simple and well organised. Work included - repairingroof leakage by removing old cable Dish, fixing the impacted area by installing new shingles. I highly recommend Alex and team for roofing jobs.

An exceptional job, extremely well done. So punctual and responsive. Alex and his associate arrived exactly when they said, gave a very competitive bid and returned the next day, again, exactly on time. The roofingrepair was completed, the clean up perfect and he also spent time clearing out my gutter. I highly recommend their service.

Alex and his staff were very professional, attentive to detail, worked in a timely manner, and answered all questions with an honest reply as I needed help with a repair on my roof. Definitely will recommend to others and request for additional services in the future.

I had a great experience with this roofer. He quickly identified the issue and clearly explained everything, even showing me a video of the roof so I could see the condition and damage myself. He was very friendly and easy to work with, and the pricing was fair. What I appreciated most was his honesty in showing the actual damage instead of overselling. Highly recommend.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Our pricing is based on the actual scope of work, materials, and doing the job correctly—not cutting corners.
We provide clear, detailed estimates so you know exactly what you’re paying for. No hidden fees, no last-minute surprises.
For repairs, pricing depends on the extent of the issue. For full replacements, we price based on size, materials, and any underlying damage.
We occasionally offer discounts for larger projects or when combining multiple services, but our focus is delivering long-term value—not just being the cheapest option.
A properly done job saves you money in the long run by avoiding repeat repairs.
What is your typical process for working with a new customer?
1. Inspection – We assess the roof and identify the real issue (not just surface problems)
2. Clear Estimate – You receive a detailed scope of work with materials, pricing, and options
3. Review & Questions – We walk you through everything so you understand exactly what you’re getting
4. Scheduling – Once approved, we schedule quickly and keep you updated
5. Installation – Professional, clean, and efficient work with full site protection
6. Final Cleanup & Warranty – Job is cleaned thoroughly and registered for warranty
No confusion, no surprises—just a clear, professional process from start to finish.
What education and/or training do you have that relates to your work?
We are a certified roofing contractor and work with top manufacturers like Owens Corning. Every completed roofing project is registered for manufacturer warranty coverage, and customers receive certification directly from the manufacturer.
Our team is trained in proper installation methods, ventilation systems, leak detection, and full roof system replacements—not just basic repairs.
In addition, we stay updated on best practices, materials, and building requirements in New Jersey to ensure every project meets professional standards.
