Common Felt Roof Problems in Lisburn
The weather throughout Lisburn and County Antrim places regular stress on felt membranes, seams and edges. Older or poorly maintained coverings can develop water ingress, damaged decking and persistent ponding.
Cracked or Split Felt
Impact damage, movement and weathering can create splits in the membrane. A local repair may be suitable where the roof still has a reasonable service life.
Blistering and Bubbling
Raised bubbles may appear where roofing layers lose adhesion. Localised blistering may be repairable, while large affected areas may make replacement more economical.
Failed Seams and Joints
Open laps can allow water beneath the roof covering. Repairs can involve renewing the affected section of felt.
Loose Edges and Upstands
The covering may pull away from fascias, kerbs or walls. A contractor may need to replace flashing and rebuild the junction.
Leaks Around Rooflights and Penetrations
Every penetration through the felt needs careful detailing. Repair work may include replacing damaged surrounding decking.
Standing Water and Poor Drainage
Large pools remaining after rain may indicate poor falls or blocked outlets. A roofer may recommend correcting low areas or improving the roof fall.
Rotten Decking and Structural Damage
Water beneath the felt may cause the deck to soften or sag. The affected felt normally needs to be removed so that the roof can be rebuilt on a stable substrate.
Storm and Wind Damage in Lisburn
Falling branches can puncture the membrane. Emergency work may involve patching damaged areas before permanent repairs are completed.
Felt Roofing Materials Available in Lisburn
High-Performance Torch-Applied Felt
High-performance felt is commonly installed in two or three compatible layers. The layers are heated and bonded together.
A typical system may include two or three bonded waterproof membranes. Torch work should be completed using appropriate safety and risk controls.
Cold-Applied Felt Roofing
Flame-free felt can be installed using cold bonding products. These systems may suit locations where hot-work restrictions apply.
Self-Adhesive Felt
Peel-and-stick membranes provide another flame-free installation method. Correct preparation remains essential, and the membrane should be installed to the manufacturer's specification.
Mineral-Surfaced Felt
A mineral-surfaced cap sheet is commonly used as the weathering layer. This helps reduce ultraviolet damage to the roof covering.
Basic Shed Felt
Economy felt can provide a simple covering for sheds and lightweight garden buildings. It generally has limited suitability for roofs above heated rooms.
Alternatives to Felt Roofing in Lisburn
Property owners in Lisburn may wish to compare felt with other modern systems. Options may include:
- Flexible rubber flat roof systems
- GRP fibreglass roofing
- Seamless liquid membranes
- Specialist commercial sheet systems
- Mastic asphalt
The Felt Roofing Process
Surveying the Roof Before Work
A contractor should inspect the roof before recommending repair or replacement. The inspection may include:
- Signs of cracks, blistering and shrinkage
- The quality of previous repairs
- Roof edges, upstands and flashing
- Skylights, pipes and service openings
- Whether blocked drainage is contributing to the problem
- The condition of the roof deck
- The condition of the roof build-up
- How the roofer can work safely
Preparing the Roof
Some jobs require only local cleaning, while complete re-felting involves stripping the old covering. Work may include:
- Preparing the damaged area for patching
- Cutting away failed felt
- Removing previous felt systems
- Waiting for suitable weather conditions
- Applying primer or preparation products
Replacing Rotten Boards
Damaged boards need to be repaired before waterproofing. Contractors may:
- Replace damaged plywood or OSB
- Address weak supporting timber
- Direct water towards gutters and outlets
- Replace rooflight kerbs and edge timbers
- Prepare a smooth roof surface
Creating the Waterproof Covering
The chosen installation method depends on the roof and felt product. Work may include:
- Installing new felt over repaired sections
- Fixing the membrane to the deck
- Adding reinforced underlay
- Installing the exposed weathering layer
- Applying hot-work procedures where appropriate
- Using cold adhesive or self-bonding systems
Waterproofing Vulnerable Junctions
Correct detailing is essential around every interruption in the roof. Contractors may complete:
- Felt upstands against walls
- Cover flashing above felt upstands
- Finished roof edges above fascia boards
- Rooflight and lantern kerbs
- Sealing roof penetrations
- Felt and flashing around parapet walls
Checking Drainage
Good drainage helps reduce stress on seams and low areas. The contractor may:
- Check that rainwater routes are open
- Repair or replace damaged outlets
- Renew damaged rainwater goods
- Reduce persistent ponding
Final Inspection and Handover
Joints, edges, outlets and repairs should be checked. The contractor may also:
- Leave the site reasonably tidy
- Provide photographs of the completed roof
- Provide workmanship and material warranty information
- Recommend future inspections
- Provide an invoice and completion documents
