Serving Markham and nearby routes
We regularly reach owners near Highway 7 and the 404 corridor and communities such as Unionville and Cornell. summer downpours that test roof lap sealant on stored rigs is hard on roof laps and slide seals — especially when rigs sit unused for months.
Whether you are pre-trip in spring or mid-season after a storm, tell us where the camper is parked. We confirm coverage for roof water damage repair in Markham before we dispatch.
What we look for on your rig
During roof water damage repair, we start with how water enters: failed sealant, cracked gaskets, loose fittings, or condensation trapped after lay-up. We follow staining, soft spots, and musty areas until the path makes sense — not just the visible damage.
Lightweight plywood, luan, and foam insulation dry differently than residential walls. We keep structure open until readings are safe, document what must be removed, and explain what can stay.
What to expect when you call
You will speak with a coordinator, not an automated queue. Share your city, RV year/make/model, and symptoms — drip, bubble, spongy floor, or odour after storage.
We quote leak tracing, drying, or rebuild scope before major demolition. If insurance needs photos or moisture logs, we can provide them when useful.
Why act before the next trip
Water that sits continues along screw lines and edge grain. Mould follows moisture that never fully dried. A smaller repair today often prevents a full floor or wall replacement later.
After work completes, we note what was fixed, what to monitor, and when to re-check seals — especially before long hauls or winter storage.

Frequently asked questions
Can you help with insurance documentation?
Many owners need photos, moisture readings, and a short summary after sudden leaks. Tell us when you call; we document what we find in a way you can share with your adjuster.
What if I only notice a smell after winter storage?
Musty odours after lay-up are common around Markham when summer downpours that test roof lap sealant on stored rigs traps moisture in closets and floors. We inspect for mould risk, dry the shell, and remove contaminated materials when readings require it.
Is roof resealing enough or do I need interior repair?
Resealing fixes the entry point; interior work fixes soaked insulation or soft wood. We check both — resealing alone does not help if plywood under the vinyl is still wet.
