Professional metal roof coating for Dover property owners. Lapolla Industries delivers lasting results with industry-leading SPF technology.
Metal roofs in Dover, NH leak at fasteners, seams, and panel overlaps — and rust compounds the problem over time. Lapolla Industries applies elastomeric coating systems that seal every failure point, treat existing rust, and create a continuous waterproof membrane over your entire metal roof.
Property owners in Dover trust Lapolla Industries for professional metal roof coating because we combine industry-leading spray foam technology with the local expertise needed to address New Hampshire climate challenges. Every project begins with a thorough assessment of your property and ends with a warranted solution engineered to last.
Our Dover metal roof coating crews arrive fully equipped with the latest SPF application systems, safety equipment, and premium materials. We handle every step — from surface preparation and substrate evaluation to final coating and cleanup — so you get a turnkey result with zero hassle and complete confidence in the finished product.
A systematic approach to metal roof coating that ensures lasting performance.
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.

"Regular maintenance visits twice a year keep our flat roof in great shape. They clean drains, check seams, inspect all penetrations, and send a detailed report with photos. Good preventive program at a reasonable cost."
"Had spray foam applied to our flat commercial roof and the difference is night and day. No more ponding water, energy bills dropped noticeably, and the seamless membrane means zero leak points. Should have done this years ago."
"When our TPO roof failed after only eight years we switched to spray foam for the replacement. The seamless application eliminates all the seam failures that plagued the old system. Three years in and it performs flawlessly."
