Your commercial roof is protecting your inventory, your equipment, your employees, and your revenue. A leak doesn't just damage the building. It shuts down operations. Londonderry Roofing & Maintenance provides commercial roofing services that keep Londonderry businesses covered and dry.

Our Commercial Roofing Process

1

Commercial Roof Assessment

Our inspector walks your commercial roof and documents every issue: ponding areas, seam failures, flashing deterioration, clogged drains, and UV damage. Photos and measurements provided in a report you can share with your property manager or ownership.

2

Detailed Proposal

Your proposal includes material specifications, installation method, warranty terms, project timeline, and total cost. We itemize everything and explain why we're recommending the specific system for your building.

3

Commercial Installation

Factory-trained crews using proper equipment, hot-air welders for TPO/PVC, torch equipment for modified bitumen, and adhesive systems for EPDM. Every seam, flashing, and penetration detail inspected before we leave.

4

Warranty & Maintenance

Manufacturer warranty registered upon completion, 15-20 year coverage depending on system and build-up. We offer maintenance contracts to keep your warranty valid and your roof performing for its full life span.

Minimal Business Disruption

We schedule around your operations. Phased installation, noise management, and debris containment. Your tenants and customers barely know we're there.

Commercial Roofing FAQ

Inadequate slope, clogged drains, compressed insulation, or settling of the building structure. Ponding water degrades membrane faster and voids some warranties. We solve it with tapered insulation systems that create positive drainage.

Absolutely. We schedule commercial work to minimize disruption. Night and weekend work is available for businesses that can't tolerate daytime noise or access restrictions. We coordinate with your property management team.

Often, yes. Localized membrane damage, failed seams, deteriorated flashings, and ponding areas can all be repaired. If the insulation is dry and the membrane is mostly intact, targeted repairs or a coating system may extend life 10-15 years.

About Our Londonderry Commercial Roofing Services

Commercial roof coatings can extend the life of an existing roof by 10-15 years for a fraction of replacement cost. Silicone and acrylic coatings over existing TPO, EPDM, or metal substrates. Not every roof qualifies. We core sample and moisture scan before recommending a coating.

Call (877) 349-1553 for a free commercial roof assessment. We inspect the membrane, flashings, drainage, penetrations, and overall condition. You get a written report with photos and our honest recommendation, repair, coat, or replace.
