Roof repair is necessary when a problem occurs. The tightness of the roof is based on the large slopes but also on the large overlaps between the roofing elements.
On the other hand, the roof has many joints and lacks the sturdy structure of the concrete slab.
When there is a problem with water leaking into a roof, the repair should be immediate. Sometimes the problem is not immediately noticeable but develops over a relative depth of time.
Once you detected the problem, irreversible damage may have already occurred. That is why a periodic inspection / inspection of the roofs is of paramount importance.
Process of roof repairing
The repair of the roof can consist of one or more of the following interventions:
- Inspection – sealing of skylights or roof windows.
Often the installation is not correct, so that they get stuck from the joint covers or from their joint with the roof.
- Check and correct the thermal insulation.
The thermal insulation should be continuous, without gaps (thermal bridges). Where there are gaps, condensation usually forms and all the elements of the roof get wet. All these weak points should be thermally insulated.
The case of lack or poor application of a water vapor barrier under thermal insulation is also considered.
The purpose of the water vapor barrier is to prevent the migration of water vapor upwards with the risk of condensation inside or above the thermal insulation.
- Check the ventilation system.
Inputs – outputs are controlled and cleaned.
Is not adequate ventilation provided?
Ventilation is necessary above the tile roof membrane but also below it, if it is not breathable.
Otherwise the development of high temperatures in combination with the inability to decongest the water vapor loads leads to failures of all the components of the roof.
- Lack of waterproofing at water collection and drainage points.
- Poorly designed, poorly maintained gutters and descents.
Reduction of their cross section due to lack of cleaning and maintenance.
A standard roof repair is to clean and better support the drainage system.
- The most common problem is the failure of watertight joints where the roof meets pipe ends, chimneys and walls of neighboring buildings.
It is true that sealing these joints is a prescribed failure because it is not done in a way that will ensure permanent protection.
- Repair of damaged asphalt tiles. Replacement of broken clay or concrete tiles.
- Reinforcement or addition of a sealing layer.
The roof needs a waterproofing layer that is durable over time. The tiles are not waterproof by themselves.
Water can pass between their gaps in a thousand and two ways.These waterproofing coatings are not properly selected or applied correctly.
Inspection and evaluation of the condition of the roof
First you need to climb the attic and find out the condition of the beams, the floor and the waterproofing layer. It is necessary to check if it is absorbed from there, if mold has appeared.
If the tree has become very faded or covered with dark spots, this may be due to constant humidity. Signs of worn roofs can be damp walls and ceilings in the rooms of the house. But in some cases, the roof on it may not be to blame.
Sometimes the whole issue is pipe leaks (water supply, sewerage or heating). There are often cases where water flows along the outer wall and then enters the house through an internal connection. An indoor roof test is best done during heavy rain, then the locations and causes of the leaks are more likely to be identified.
Roof damage repair
If there is a broken tile, or cracks have been created in your tile roof, it is deemed necessary to repair the damage, immediately. To repair the damage, first the spot should be thoroughly cleaned, the remnants of mud, dust or tree leaves removed and the worn tiles peeled off.
Next, repair cement mortar should be used to close the holes and install new tiles at the site. Now, several methods have been developed to create tiles in the same color as the existing ones. Thus, when the new tiles are laid, there will be uniformity in the tile roof.
Once the work is completed and it is ensured that no more water enters from the tiles, you can proceed with works for the insulation of the tiled roof outside. Tile waterproofing is a fairly easy process and will help seal the tile roof, so that no water enters the tiles every time it rains. For the absolute waterproofing, first the tiled roof should be primed and then a special material should be coated.
