Ridge cap cleaning, ridge pointing and repair work
Ridge capping is the triangular-shaped tiles that sit at the highest point of the roof where two roof areas intersect. Repointing is a term used for resealing the ridge capping mortar when the existing mortar is cracked, allowing water penetration.
Typical ridge capping work includes:
- Replaced broken roof tiles through-out the roof including 1 valley cut and 2 under the ridge capping
- Re-fixing small corners into place with flexi-point or sealant
- Clean and seal all aerial bolts, cracked lead and protrusions etc. where necessary
- Strip up the base of valleys, cleaning out rubbish and then re-assembling
- Clean leaf debris from gutters where necessary
- Clip loose valley cuts where necessary
- High pressure water blast all ridge capping concrete on the roof
- Cut back top edge of all ridge capping with a grinder
- Repoint all ridge capping in flexible pointing
The cleaning removes dirt and loose pointing and readies the caps for repointing. If the caps are not cleaned the new flexipoint may peel off within 2 years.
Flexipoint ridge capping
We repoint ridge capping in flexible pointing, applied in a trowel finish over all existing cement work. This bonds the capping to the roof tiles preventing any further deterioration and creates a long-lasting durable finish.
What is the warranty on repointing?
Flexible pointing comes with a 5-year factory warranty. The mortar used for pointing is a key element in roof repairs.
Are new tiles used?
Second hand tiles will be used. Colour may differ. Tiles will be placed on lower side of the roof where they are less noticeable.
What does repointing a roof mean?
Roof repointing is the resealing of mortar around the ridge tiles. This involves cleaning the ridge capping and applying the new repointing material.
How much does it cost to repoint a roof?
Roof repointing can cost $20 to $25 per lineal metre, depending on the size of your roof and other factors. Repointing the average roof is around $1500 to $2500 plus GST.
How long does roof pointing last?
Approximately 10 years but can go to 20 years.
What is the difference between bedding and pointing?
Rebedding is removing the ridge capping completely, stripping up the old concrete, running out a new bed of mud (sand/cement), then pointing the caps in flexipoint. Repointing is going over the existing capping, leaving it in place, we do water blast the old capping cement first so the new flexipoint adheres properly.
How often should you repoint a roof?
When the concrete is beginning to crack throughout and/or the bed starts falling apart.
Can you repoint over old pointing?
Yes, only if the old bedding is still flush with the top edge of the ridge cap.
Is roof pointing waterproof?
No, it is porous, hence weep holes need to be installed to the caps.
Can you use pointing for bedding?
What is the mix roof bedding mortar?
Bedding mix is a ratio of around 5 or 6 to 1, sand to cement.
