DRY VENTILATION SYSTEMS
Cracked mortar? Loose ridge tiles? Damp appearing in the loft?
It's not your tiles that fail — it's the concrete. Your roof needs to breathe
Old cement ridges can't flex with your roof, so they crack, trap moisture, and block essential ventilation, leading to leaks, mould, and timber rot.
Our team at Shelter Essex Roofing installs modern dry fix ventilation systems that keep your roof secure, weatherproof, and properly ventilated for decades. No mortar. No cracking. No repeat repairs – just long-lasting, fully ventilated protection.
Do Any of These Problems Sound Familiar?
Condensation or dampness in your loft space. Musty smells or visible mould growth
Ridge tiles loose or slipping out of place. Cracked or crumbling mortar along the roof ridge
Cold spots in upstairs rooms or high heating bills. Damp patches appearing on bedroom ceilings
If you’ve noticed any of these, you’re not alone. These issues all point to one root cause: your roof can no longer breathe properly. When ventilation stops, moisture becomes trapped – and small problems quickly turn into expensive damage.
The Hidden Problem: Why Traditional Roofs Fail
Most homes in Essex have roofs with cement-bedded ridge tiles. For decades, this was the standard way to secure ridge tiles and keep weather out. But there’s a fundamental problem with cement mortar that nobody talks about.
The Cement Problem: Your roof moves. Cement doesn’t
Every day, your roof expands and contracts with changes in temperature. Wind constantly flexes the structure. Rain, frost and sun all take their toll. Weather wears at every surface. Cement can’t cope with this movement – so it cracks. Once it cracks, water gets underneath the ridge tiles. It sits there, trapped, with nowhere to go. Ventilation is blocked, and your roof can no longer 'breathe'.
What Happens When Moisture Gets Trapped?
When your roof can't breathe properly and moisture becomes trapped, it causes a cascade of expensive problems:
Rotting roof timbers: Water-soaked timber loses strength and eventually fails. Replacing roof timbers means major structural work costing thousands of pounds.
Ruined insulation: Wet loft insulation is useless. Your heating bills soar whilst your home stays cold.
Mould and health issues: Damp conditions create the perfect environment for black mould, which can cause respiratory problems.
Damaged ceilings and decoration: Water finds its way down, staining ceilings and ruining your interior.
Failing ridge tiles: Without secure mortar, tiles become loose. They can slip or blow off completely in high winds.
Here's the thing most roofers won't tell you: repointing with fresh cement just resets the clock. It'll last another 15-20 years and then fail again in exactly the same way. You're paying for a temporary fix, not a permanent solution.
The Modern Solution: Dry Fix Ventilation Systems
There’s a better way to secure your roof that’s been used on new builds for over 20 years. It’s called a dry fix ventilation system, and we love installing it because it solves the problems cement mortar creates.
How Dry Fix Ventilation Systems Work
Instead of brittle mortar, dry fix systems use engineered fixings and interlocking parts to securely hold everything in place. They flex with your roof’s natural movement, remain weatherproof, and provide continuous ventilation along the entire ridge.
Why Ventilation Matters
Your roof space naturally produces warm, moist air. In the kitchen, bathroom, from washing, and even from breathing. This air rises into your loft. If it can't escape, it condenses on cold surfaces, creating all those problems we mentioned earlier. Dry fix ventilation systems include ventilated ridge components that allow this moisture-laden air to continuously escape whilst keeping rain and weather out. Your roof literally breathes, preventing condensation, mould and timber rot.
Why Upgrade?
Traditional Cement Mortar
Rigid and inflexible
Cracks within 15-20 years
Traps moisture in roof space
Requires regular repointing
Ridge tiles can become loose
No ventilation
Causes damp and timber rot
Modern Dry Fix Systems
Flexible with roof movement
Lasts decades with no maintenance
Continuous ventilation
No repointing ever needed
Mechanically fixed and extremely secure
Built-in weatherproofing
Protects timbers and insulations
Benefits You'll Actually Notice
Lower energy bills: Proper ventilation keeps your insulation dry and working properly. Dry insulation keeps heat in far more effectively than damp insulation.
Healthier home: No more condensation means no mould growth. Better for your family’s health and your home’s air quality.
Protected investment: Your roof timbers stay dry and solid. No expensive structural repairs down the line.
Storm-proof security: Mechanical fixings are far stronger than cement in high winds. Your ridge tiles aren’t going anywhere.
Future-proofed: Meets all current Building Regulations for ventilation. You won’t need to upgrade if standards change again.
Set and forget: No maintenance required. No repointing every 15 years. It’s done properly, once.

Frequently asked questions
Common Questions About Dry Fix Ventilation Systems
How long does installation take?
Most residential properties can be completed in 1-2 days, depending on roof size and complexity. We'll give you an exact timeframe after inspection.
Will it work on my type of roof?
Dry fix systems work with virtually all roof types and tile styles. Whether you have concrete tiles, clay tiles, or other materials, there's a suitable system.
What's involved in the work?
We remove the old mortar and ridge tiles, prepare the roof surface, install the mechanical fixing system and ventilation components, then secure the ridge tiles back in place. Everything is done from outside – no mess in your home.
How much disruption should I expect?
Minimal. All work is external. You can stay in your home as normal. There'll be some noise during working hours, but we keep everything tidy and clean up completely at the end of each day.
How does the cost compare to traditional repointing?
Dry fix systems cost roughly the same as quality repointing work initially, but they last 3-4 times longer and require no maintenance. Over the lifetime of your roof, dry fix is significantly better value.
What guarantee do you offer?
We provide comprehensive guarantees covering both materials and workmanship. Specific terms depend on the system installed, but you'll have complete protection.
Do I need planning permission?
No. Replacing existing roof components with modern equivalents is considered maintenance and doesn't require planning permission in most cases.
What if I just have a small section that needs work?
We can install dry fix systems on any size area. However, since the lifespan of cement mortar is similar across your whole roof, it often makes sense to do the complete ridge while scaffolding is in place.
