Although we do not want to and we adopt good practices of maintenance, the passing of the years affects the different aspects of the construction, and the elements that give the exterior, such as facades and roofs, are the most punished.
In the long run, we should practice rehabilitation in a roof or cover, even if it is a specific point and a minimal performance, but we will have to get down to business work.
The problems that can appear on the roofs and roofs for residential buildings require a fast and effective solution with an added problem, are complex as we can see in the following image…
By staying in poor condition, the only thing you get is to accelerate the speed with which it deteriorates, each being more and more expensive the necessary repair to leave it again in conditions.

Determine the type of roof on which we are going to work on the rehabilitation and how it is built is a essential point to treat the pathologies in the construction .
In this sense, we will rely on a documentation of the Valencian Building Institute (IVE) which houses 10 information documents; 3 on pitched roofs and 7 on flat roofs. Each document is structured:
The classification and download access of all following documents is from IVE (We registered and the PDF download is free):
If we want to see more information, from the article on the types of constructions and their technical solutions we will find more details but referred to by periods and times. and in the case of a more complex roof from the perspective of landscaped, we can consult the article on green roofs where you will find several valuable manuals and documentation technique.
The general causes of pathologies in covers is actually a long topic but in the following scheme we can check the generic origins of pathologies in %:
As can be seen in the previous diagram (Los %), the main causes do not always respond precisely to one certain old age on the deck, for the most part are causes above, derived from the project and its construction. If we we go a little deeper into the information, we have a diagnosis of pathologies on roofs a outline mode:
The two diagrams above are from the document Manual de Pathology in Building HERE from the University Polytechnic of Madrid. Furthermore, for its usefulness we recommend also see the following two articles:
The main problem affecting roofs is the presence of moisture . water is the enemy construction, since it can lead to spoiling everything in a very short time time.
The appearance of moisture inside the cover of the housing can come from different anomalies that is convenient to identify correctly in order to attack effectively the root of the disease, being able to remove totally the mistake.
But apart from humidity, the simple passing of the years can be also a reason for the roof of the house to require of a restoration. Wooden structural elements can lose resistance over the years due to lack of maintenance, presence of insects that reduce its section, are some of the inconveniences that can arise in constructions that already have years of existence.
First, to be clear about what we are talking about in a schematic and to be able to see how they are and where they appear, causes possible, considerations and how it can be prevented. we contribute a very useful scheme:
At this point, we have to remember that we must act quickly on the types of humidity in the covered with tile and flat due to its consequences negative, and that they should be consistently treated as They comment very well on the portal humedades24.com that summary mode for hygrometry problems, moisture or steam are:
When injuries are detected, they should never be repaired by bending the pavement. The existing pavement should be lifted and start the repair of the problems. Next we add let's see the procedures and videos explaining processes and technical solutions.
In tile roofs, moisture may appear in the interior, and in a more extreme case directly find leaks.
If it's a one-off problem, chances are it's been broken a piece of tile, so the solution is easy: replacement of broken part and finished matter.
Keep in mind that the problem does not have to be necessarily in the place where the drop falls, because it is It is probable that it slides by some element of the cover until it detaches in that place.
If it is a nailed piece of slate, a nail puller to remove the tile. The claw puller slides through under the piece and hit to remove the nails from fixation. All fragments are then removed broken and a new slate is slid under the row top.
The slate is nailed down with exposed galvanized nails. Is It is important to protect the heads with caulk to prevent leaks. To better understand how to replace a tile, we leave the next video:
When the presence of leaks and humidity is widespread on the entire deck then you have to think of something more serious and therefore more expensive rehabilitation.
In an old cover, it is very likely that the appearance of leaks and humidity on the entire surface is due to the absence of waterproofing. In this case the solution is to raise the entire roof, place a waterproofing membrane and retile.
It is important to define which are the most suitable materials to rehabilitate the roof and in these cases the evidence of a professional is, in our opinion, essential, although We leave a video of how to place an asphalt cloth to the most daring:
If the cover is not that old, and it is known for science certain that it has a correct waterproofing, and still so that leaks appear, it is very likely that the slope of the cover is insufficient.
This is a serious problem, since the only possible solution is to make the roof of the house again. One has to dismantle the entire cover, including its structure, and return it to do with a greater slope.
In general we can find the following weak points that we must review:
If there is moisture on the entire flat roof, it is best to completely rehabilitate the roof making a correct waterproofing.
In these cases it is best to place a PVC or EPDM sheet (it is a type of rubber sheet) covering the entire surface of the roof or place asphalt cloth waterproofing like the previous video. An example of installing an EPDM sheet:
When on a flat roof the appearance of water is punctual, the aforementioned materials are not the most advisable. Placing patches of these materials means that there are many together, and the possibilities that the water leaks through them, so the problem is not only solves but can get worse.
For specific repairs on flat roofs, the best thing to do is use the materials with which one works in situ, such as They can be bituminous, waterproofing sheets and paintings.
Everything related to the rehabilitation of roofs must be done by specialized personnel, because it is a very important aspect 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 good insulation, absence of moisture and leaks.
Leaks that form through roofs and roofs usually follow a course until they show up as a stain on Wall. Leaks often occur between the deteriorated profiles or in a hole left by a tile loose, if it is sunny, the leak can be located as a point of light.
If you see any, drive a nail into the roof of the house from bottom to top through the roof, to mark the point to seal A string is tied to the nail to guide the water into a bucket until said leak is repaired.
The circulation of air under the tiles prevents the contrast of temperatures between the roof surface and the bottom lower. The solution is to achieve proper ventilation and insulation of the house during its construction.
Different types of vents can be installed (for professionals, since the work is of importance) in several parts of the building: the grid strips, which provide a lot of air; the exits on the ridge, very discreet; the classics pinnacles, difficult to build but very decorative, and the attic exits, suitable for very flat roofs spacious.
Installing a screen in the gutter is a great idea so that leaves and large debris do not slip through and obstruct You have to buy the grid to measure or cut it with the help of a pliers. Slide inside edge under of the first row of tiles or plates and fold the grid of so that it fits the edges.
If you add a wire filter, also known as a cage, the possibility of clogging in the downspouts.
A cracked chimney flue needs to be fixed immediately, as it can be dangerous. the cracks They usually appear in the union of stones or bricks and for their repair, it is enough to empty these joints and inject a mortar more or less fluid If the cracks affect surfaces interiors, it is better to leave the job in the hands of a professional.
A good insulation system for a roof is sandwich panels. It is a product made up of three hats; the insulating material is placed in the center of each piece and, as for the other two faces, one is of finished in varnished wood (what will be the ceiling of the housing), and the upper layer of the panel is the one that supports the tile or the type of coating you want.
Between the tile and the sandwich panel it is advisable to put a insulation sheet and take care of the auctions and meetings to that there are no water leaks.
When a part of the waterproofing sheet of a terrace deteriorates or cracks, it can be patched easy following a few tips.
The waterproofing of flat roofs with membrane or elastomer sheets is usually the usual procedure for insulate terraces. When the reform is carried out, it is not It is advisable to throw away the excess of the coating, because if it cracks some area of the ground with the passage of time, it is can easily patch.
To do this, the adhesive is applied around the leak. A round patch is cut from a remnant of elastomer sheet, and the patch is placed, press to adjust it. tighten with a roller and wait 30 minutes until the solvent of the adhesive has dried; then, with a silicone gun, seal the edges of the patch and flatten the sealing bead with a spatula so that the water slides off and does not stagnate.
Climbing on a roof implies a certain danger and more if the building is tall, so it is important to respect some safety rules. No need to work when the deck is wet or icy, and proper footwear should be worn. anti-slip. It is also important to find the point of fixing the ladder, which will have a separator to rest it on the wall, not on the gutter.
First we must comment that professionals are, among other things, to provide us with an adequate budget and to measure for the rehabilitation of our roof or roof the House. But if we want to have a general idea we can always consult a database of the construction.
We can check the prices from the IVE database HERE (The price bases are updated every year and are from 2007 – 2019). By the way, if you want to consult other prices to compare, from the article generators of prices for construction there is more information.
Remember that summer is an ideal time to take carry out DIY work abroad. A good maintenance of the roofs and covers guarantees the insulation and therefore, the absence of those annoying stains of humidity and leaks that visit us at the time winter.
