Public Records Check

  • Missing License Our automated search didn't find a license on file for Roland Slate Service Co., Inc. with the Maryland state licensing board. That doesn't mean the company is unlicensed. A license can be held under a different business name, registered too recently for us to match, or filed in a way our search didn't catch. We recommend confirming directly with the Maryland state licensing board or asking the contractor for their license number.
  • Registered Corporation The Maryland Secretary of State listed Roland Slate Service Co., Inc. as INCORPORATED when we last checked on Jul 3, 2026, registered since 2021. You can confirm it's still current with the Maryland Secretary of State.
  • Business Address Roland Slate Service Co., Inc.'s listed address at 325 W. 23rd St., Baltimore, MD 21211 appears to be a business address. This means the company operates from a real, locatable address rather than a mailbox or PO box, which can make it easier to reach them or resolve issues. Many roofers legitimately work from a home address, so this doesn't speak to the quality of their work, license, or insurance.
  • 1 Credential Roland Slate Service Co., Inc. holds these manufacturer certifications: CertainTeed ShingleMaster. These show the company met a manufacturer's program requirements and may offer manufacturer-backed warranties, but they aren't independent quality audits. You can confirm current status with the manufacturer.
  • Excellent Ratings Across the platforms we identified for Roland Slate Service Co., Inc. (Google, Yelp, the Better Business Bureau), the blended average is 4.9 out of 5, which we label Excellent. This is a plain average of public customer ratings, not a RooferWatch score. A high average reflects past customers' experiences, not a guarantee of yours, so read the underlying reviews and weigh them yourself.

We verified 4/5 public records for Roland Slate Service Co., Inc.. The more of a company's record you can check, the more informed your hiring decision.

About this review summary

This summary was automatically generated from customer reviews that were publicly visible at the time it was created on one or more of the review aggregators listed below. It does not constitute a review, rating, endorsement, or statement of fact about the business - it reflects only the opinions expressed by those reviewers as found at that time, not the views or conclusions of RooferWatch. Automated summaries can contain errors or omit context and may become outdated as new reviews are posted, so please read the original reviews through the links provided and do your own due diligence. If you are the business owner and believe anything here is inaccurate, submit a correction and we’ll review it promptly.
  • Avg. Rating 4.9
  • BBB A+
  • Google 4.9

Reviewers consistently praise Roland Slate's service quality and workmanship. Several customers report the team was punctual, professional, and attentive, with responsive staff and crew members who went above and beyond expectations. Multiple reviewers describe the quality of work as excellent and thorough, with one customer expressing confidence the slate work will last for decades. Reviewers highlight positive interactions with named staff members and appreciate the company's honesty and transparency. However, some customers note communication challenges: one reviewer reports delayed communication between estimate signing and work start, while another describes scheduling confusion and unclear completion notifications. One reviewer mentions the crew did not conduct a final walkthrough as contractually mentioned. Several long-term customers report satisfaction with the company's service over years of roof and chimney maintenance.

About this average rating

This figure is a straightforward average of the public ratings we’ve gathered for this company across the following review platforms that our systems have identified: Google, Yelp, the Better Business Bureau. It is not a proprietary RooferWatch score or a judgement of our own; each source is converted to a common five-star scale and blended into a single number so that no one platform’s reviews carry outsized weight, giving a more balanced read on overall sentiment. We’d still encourage you to read the underlying reviews on each platform and weigh them for yourself.

Review Signals Over Time

These figures are derived from this company’s 30 most recent publicly visible Google reviews at the time they were gathered. They simply describe patterns in those reviews - how often new reviews appear, how often the owner replies, and whether recent star ratings run higher or lower than older ones. They are not a review, rating, endorsement, or judgement by RooferWatch, and they reflect only what those public reviews showed at that time, which can change as new reviews are posted. Please read the underlying reviews and do your own due diligence. If you are the business owner and believe anything here is inaccurate, submit a correction and we’ll review it promptly.
