Leaks at Roof Transitions
- You See
- Stains on the wall where an addition meets the main building.
- What It Means
- The two roofs move differently. The joint gets new flashing and reinforced coating across it.

Service Area · Canton, CT
As a Canton metal roof coating contractor, we coat older shop, office, and light industrial roofs that join pitched metal, flat additions, and shingle sections.

Canton metal roof coating jobs often cover a building that grew over time: a pitched metal main roof, a flat addition at the back, and maybe a shingle office wing.
Each section gets the system its slope and material call for, and the joints where sections meet get the most attention, since water collects and moves there.
On mixed Canton roofs, trouble collects at the transitions more than in the open field.
Coating a mixed Canton roof as one project brings four practical gains.
Every roof area is inspected and priced together, so joints are handled once.
The joints between roof types get flashing and coating that tie the sections together.
Shops and offices below keep running while each section is worked in turn.
Coated sections hold off replacement and recoat later without tear-off.
A single Canton building can use two or three of these options at once.

The main pitched steel roof on an older Canton shop takes the standard metal system after fastener and rust work.

Office wings in Canton with flat-lying shingles get a coating made for asphalt.
Bristol Shingle Roof CoatingThose transition leaks are common on older Canton buildings. Call us and we will check the joint and both roof sections.
Mixed roofs add a step: deciding which system goes on which section.
We walk every section, note its slope and material, check drainage and fasteners, and mark each transition between roof types.
Pitched metal, flat additions, and shingle wings each get a system, written into one estimate with a line per section.
Joints between sections get new flashing and fabric-reinforced coating before any field coat.
Each section is coated to its own spec, so tenants below know which part of the roof is being worked.
Canton, including Collinsville, sits in our coverage from Bristol. Not on the list? Call us or send us a message.
Yes, across Canton and the Collinsville area, from shops and offices to storage and light industrial buildings. Mixed roof sections are common here, so every section is inspected before a system is picked.
Each section is priced from the published $2.50 to $4.00 per square foot range, adjusted for its prep and system. Transition work is listed separately so you can see what the joints add.
It can. A flat addition that ponds can take silicone while a pitched metal roof takes acrylic or the standard metal coat. The joint between them is flashed so the two systems meet cleanly.
We are, working from Bristol with Canton and Collinsville on our regular list. A phone call or the estimate form sets up the roof walk.
Doing both together is often easier, since staging and access are already set. If the shingles are curled or missing, reshingling that wing comes first and the metal sections are coated on their own schedule.
The Canton building department decides based on scope. Coating work that also replaces panels, changes structure, or adds insulation is the kind most likely to need a permit, so those parts are listed separately in the estimate.
Tenants under each section hear about its work day ahead of time. Staging stays clear of their doors, and noisy steps like grinding are scheduled with the building owner.
Reshingling that wing comes first, and the metal and flat sections can still be coated on their own schedule. The estimate shows the wing as a separate line so you can plan it with a roofer of your choice.
Describe the sections on your building. We will inspect each one and price them together.
