Expert roof waterproofing in Calverton, MD. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Waterproofing a roof in Calverton, MD requires more than paint-on products that peel and crack. Lapolla Industries applies spray foam and elastomeric membranes that create a true monolithic waterproof barrier — no seams, no joints, no weak points where Maryland rain can find a path inside.
When Calverton, MD property owners need roof waterproofing, they turn to Lapolla Industries for the same reason thousands of customers nationwide do: we solve the root problem, not just the symptom. Our diagnostic approach uses infrared scanning, moisture mapping, and visual inspection to ensure the solution we recommend is the one your building actually needs.
With over two decades of spray foam experience, our Calverton crews have seen every roof waterproofing scenario Maryland weather can create. We use that experience to select the right foam type, coating system, and application method for your specific property — delivering roof waterproofing results that hold up to Calverton conditions year after year.
From inspection to completion, here is how we deliver professional roof waterproofing results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
We prepare every surface according to factory guidelines — cleaning contaminants, addressing moisture, repairing damaged substrate, and verifying adhesion conditions. This step is not glamorous, but it is the foundation of a spray foam system that lasts decades.
Our factory-trained crews apply spray polyurethane foam using calibrated equipment that ensures consistent thickness, proper density, and complete coverage. The foam expands on contact, fills every gap, and bonds permanently to the prepared substrate.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Our reputation is built on results. Here is what our customers have to say.
"Our foam roof had some blistering and a couple of punctures from a maintenance crew walking on it. They repaired everything in one visit — cut out the damaged foam, re-sprayed, and recoated. Good as new."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
"We signed up for their annual roof maintenance program for our three commercial buildings. They catch small issues before they become expensive repairs. Last inspection they found a failing pipe boot that would have caused a major leak."
