If there is moisture throughout the flat roof, it is best to fully rehabilitate the roof making proper waterproofing.
In these cases, it is best to place a sheet of PVC or EPDM (it is a type of rubber sheet) covering the entire surface of the roof or place asphalt waterproofing fabric. An example of installing an EPDM sheet:
When the appearance of water is punctual on a flat roof, the aforementioned materials are not advisable. Placing patches of these materials means that there are many joints, and the possibilities of water leaking through them are widened, so that the problem is not only solved but can be aggravated.
For punctual repairs on flat roofs it is best to use the materials with which one works in situ, such as bituminous, waterproofing sheets and paints.
Everything that does to the rehabilitation of roofs must be done by specialized personnel, because it is a very important part of the building that must be ensured that it provides good results and for a long time.

A perfect maintenance of the exteriors of the houses guarantees a good isolation, absence of humidity and leaks.
The leaks that form through roofs and decks usually follow a course until they show up as a stain on the wall. Often, the leaks occur between the damaged profiles or in some hole that has left a loose tile, if it is sunny, the leak can be located as a point of light. If one is seen, a nail must be inserted into the roof of the house from the bottom up through the roof, to mark the point to be sealed. A string is attached to the nail to guide the water into a bucket until the leak is repaired.
Prevent possible effects of condensation
The circulation of air under the tiles prevents the contrast of temperatures between the roof surface and the bottom. The solution is to achieve proper ventilation and insulation of the home during its construction.
The different types of vents can be installed (by professionals, since the work is important) in several parts of the building: the grid strips, which provide enough air; the exits at the ridge, very discreet; the classic pinnacles, difficult to build but very decorative, and the outlets in dormers, suitable for very wide flat roofs.
Gutters without obstructions
Installing a grid in the gutter is a great idea so that the leaves and large debris do not strain and block it. You have to buy the grid to size or cut it with the help of a pincer. Slide the inner edge under the first row of tiles or plates and fold the rack so that it fits the edges. If a wire filter, also known as a cage, is added, the possibility of clogging in the downspouts is eliminated.
A cracked chimney duct must be repaired immediately, as it can be dangerous. The cracks usually appear at the junction of stones or bricks and for their repair it is enough to empty these joints and inject a more or less fluid mortar.
Sandwich panels, insulate and decorate
A good roof insulation system is sandwich panels. It is a product composed of three layers; The heat-insulating material is placed in the centre of each piece and, as for the other two faces, one is finished in varnished wood (which will be the roof of the house), and the top layer of the panel is what supports the tile or the type of coating that is desired. Between the tile and the sandwich panel it is advisable to put an insulation sheet and take care of the auctions and meetings so that water leaks do not occur.
When a part of the waterproofing sheet of a terrace deteriorates or cracks, it can be easily patched by following some advice.
Patch a flat cover
The waterproofing of flat roofs with membrane or elastomer sheets is usually the usual procedure of insulating terraces. When the reform is carried out, it is not advisable to throw away the excess of the lining, because if any area of the floor cracks over time, it can be easily patched. To do this, the adhesive is applied around the filtration. A round patch of a remaining elastomer sheet is cut, and the patch is placed, press to adjust. Press with a roller and wait 30 minutes until the adhesive solvent has dried; then, with a silicone gun, seal the edges of the patch and flatten the sealant with a spatula so that the water slips and does not stagnate.
Choose safe stairs
Climbing a roof implies a certain danger and more if the building is high, it is therefore important to respect some safety regulations. There is no need to work when the cover is wet or freezing, and non-slip footwear should be worn. It is also important to look for the fixing point of the ladder, which will have a separator to support it on the wall, not on the gutter.
