A small roof problem today becomes an expensive disaster tomorrow. Water finds its way through the tiniest gap, soaking timbers, ruining ceilings, and creating perfect conditions for mould and rot.
JB Contractors provides fast, effective roof repairs throughout Plymouth and across Devon and Cornwall. Most repairs can be completed in a single visit, stopping damage before it spreads.
Common Roof Repairs in Plymouth
Plymouth's weather throws everything at your roof – Atlantic storms, driving rain, salt air near the coast, and freeze-thaw cycles inland. Here are the repairs we carry out most often:
Slipped and Missing Tiles
High winds are the main culprit. Tiles can slip when the nibs break or fixings fail, leaving gaps for water to enter. We replace damaged tiles and refix surrounding ones to prevent recurrence. We carry common tile types so repairs can often be completed immediately.
Cracked and Broken Tiles
Frost damage, impact from debris, and simple age cause tiles to crack. Even hairline cracks let water through. We remove broken tiles and fit replacements that match your existing roof.
Ridge Tile Repairs
The mortar bedding ridge tiles eventually fails, allowing tiles to rock, leak, and potentially blow off in storms. We can repoint existing ridges or install modern dry ridge systems that require no maintenance.
Valley Repairs
Valleys channel water from two roof slopes and take tremendous punishment. Lead valleys can crack, felt valleys perish, and tile valleys block with debris. We repair or replace valleys to restore proper drainage.
Flashing Repairs
Lead flashings around chimneys, walls, and roof windows seal critical joints. When they crack, lift, or corrode, water pours into your home. We dress down lifted flashings, patch cracks, or replace sections as needed.
Leak Detection and Repair
Not all leaks are obvious. Water can travel along timbers before dripping through your ceiling, making the source hard to find. Our experienced roofers trace leaks to their origin and fix them permanently.
Storm Damage Repairs
After severe weather, we see a surge in calls from across Plymouth. We prioritise making properties weathertight, often with temporary repairs, before returning for permanent fixes. We also provide reports for insurance claims.
Our Repair Process
Assessment
We inspect your roof from ground level, from a ladder, or using drone photography for complex roofs. This allows us to identify all issues, not just the obvious ones.
Clear Quotation
You'll receive a written quote detailing exactly what work is needed and what it will cost. No vague estimates, no surprises.
Efficient Repair
Our van carries common tiles, lead, sealants, and fixings. Many repairs are completed the same day you call. For larger jobs, we schedule at your convenience.
Quality Check
Before we leave, we check our repairs from inside your loft (where accessible) to ensure everything is watertight. We also inspect surrounding areas for potential future problems.
Repair vs Replace: Honest Advice
We'll always tell you the truth about your roof's condition. Sometimes repairs are the right choice – extending your roof's life cost-effectively. Other times, ongoing repairs become a false economy and replacement makes more sense.
We won't push you towards expensive work you don't need, and we won't patch up a roof that's clearly failing. You'll get honest advice based on what's actually best for your property.
