After months of high temperatures, intense sun exposure and prolonged periods without precipitation, small damages that have gone unnoticed can become apparent when the first episodes of heavy rain arrive.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">A crack, a partially clogged drain, a damaged joint or a poorly resolved singular point can end up causing water accumulation and, over time, leaks inside the building.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Therefore, anticipating is much more effective than waiting for a leak to appear.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">At <strong>IMPERA<\/strong> we recommend taking advantage of the last weeks of summer to review the general condition of the roofs and detect possible incidents before the weather conditions become more demanding.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">Why check the roof after summer?<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">During the hottest months, roofs are one of the parts of the building that endure the most intense environmental exposure.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Solar radiation, high temperatures and thermal changes between day and night can progressively affect the different elements that make up the roof system.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">This exposure does not necessarily mean that there is a waterproofing problem, but it does make it advisable to periodically check its condition.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">In fact, the consequences of a small deterioration may not be visible for weeks. It is common for the first symptoms to appear with the arrival of the first rains.<\/p>\n\n<p class=\"wp-block-paragraph\">For this reason, a <strong>preventive review before autumn<\/strong> allows us to act on possible incidents at a time when significant damage has not yet occurred.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">Clean drains, channels and drainage systems<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">One of the first elements that must be reviewed are the systems responsible for evacuating the water.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">During the dry months, leaves, dust, sand and other debris can accumulate in <strong>drains, gutters and downspouts<\/strong> . When heavy rainfall occurs, these materials can hinder drainage and cause water to accumulate on the roof.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">On a flat roof, the correct functioning of the evacuation system is especially important.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">A small obstruction can cause water to take much longer to disappear or to accumulate in certain areas. If this phenomenon is repeated, the demand on the waterproof system increases.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">On the IMPERA website we have already explained <a href=\"https:\/\/impera.cat\/en\/why-many-flat-roofs-accumulate-water-even-when-they-are-new\/\">why some flat roofs accumulate water even when they are new<\/a> and what factors can cause this problem.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Therefore, periodic cleaning of drainage points is a simple but essential action within the maintenance of a roof.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">Check the condition of joints and singular points<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Not all areas of a roof present the same level of risk.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">The encounters between different materials, perimeters, joints, drains, installation passages or connections with vertical walls are <strong>unique points that require particularly precise execution<\/strong> .<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Over time, the building&#8217;s own movements and temperature changes can affect these points.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">A visual inspection can detect signs such as:<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<ul class=\"wp-block-list\">\n<li>fissures or cracks;<\/li>\n\n\n\n<li>damaged joints;<\/li>\n\n\n\n<li>separations between materials;<\/li>\n\n\n\n<li>raised or deformed membranes;<\/li>\n\n\n\n<li>seals in poor condition;<\/li>\n\n\n\n<li>areas where water tends to accumulate.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Detecting these signals before the rains allows us to assess whether specific action is necessary.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">A small crack is not always a small problem<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">One of the most common mistakes is to assess an incident solely by its visible size.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">A crack of a few millimeters may seem unimportant, but if it affects the continuity of the waterproof system it can become a water entry point.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Furthermore, the place where moisture appears indoors does not always coincide with the exact point where the water enters.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Water can move between different building layers before becoming visible, making it difficult to identify its origin once the leak has occurred.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Therefore, when faced with any sign of deterioration, it is preferable to check the origin before waiting for the problem to evolve.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">Also check the walkable terraces<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Walkable terraces<\/strong> require special attention because, in addition to weather exposure, they withstand daily use.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Outdoor furniture, planters, decorative elements, installations or simply the traffic of people can affect certain points if the construction solution is not prepared adequately.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Before the rainy season it is especially advisable to check:<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<ul class=\"wp-block-list\">\n<li>the state of the boards;<\/li>\n\n\n\n<li>the perimeters;<\/li>\n\n\n\n<li>the drains;<\/li>\n\n\n\n<li>the encounters with doors and facades;<\/li>\n\n\n\n<li>the existence of broken parts or damaged areas;<\/li>\n\n\n\n<li>possible signs of humidity in lower spaces.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">In these types of spaces it is especially important to remember that the visible surface is not necessarily the layer that guarantees watertightness. In the article on <a href=\"https:\/\/impera.cat\/en\/waterproofing-walkable-terraces-systems-materials-and-mistakes-to-avoid\/\">waterproofing walkable terraces<\/a> we explain the different systems and some of the errors that can compromise the result.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">Don&#8217;t wait for a leak to appear<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">When a moisture stain or leak appears, the problem has already overcome the building&#8217;s first protective barrier.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">In some cases, water may have previously affected other hidden elements before becoming visible from the interior.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">For this reason, the main objective of <strong>preventive roof maintenance<\/strong> is to detect incidents before they become a more complex repair.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">At <strong>IMPERA<\/strong> we have incorporated a <a href=\"https:\/\/impera.cat\/en\/impera-presents-its-new-preventive-maintenance-service-for-neighborhood-communities-and-industrial-buildings\/\">preventive maintenance service for roofs for residential communities and industrial buildings<\/a> , which includes the periodic review of the most sensitive elements and allows us to anticipate possible incidents.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">This preventive philosophy is especially interesting before periods of the year when the probability of precipitation increases.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">Roofs of communities and industrial buildings: prevention is even more important<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">In a community of owners, a leak originating on the roof can end up affecting homes, common areas or facilities in the building.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">In an <strong>industrial building<\/strong> , the consequences can be even more important if water reaches production areas, goods, equipment or electrical installations.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">In addition, industrial roofs tend to have much larger surfaces and numerous unique points: skylights, air conditioning equipment, ducts, photovoltaic installations, drains or technical passages.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">A periodic inspection allows you to know the real condition of the roof and plan the necessary actions in time, instead of having to intervene urgently during an episode of rain.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<h4 class=\"wp-block-heading\">End of summer: get ahead of the rain before it arrives<\/h4>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Preparing a deck for fall doesn&#8217;t mean waterproofing it again every year.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">In many cases, a correct inspection, cleaning of the drainage systems and timely repair of damaged elements are sufficient to maintain the system in good condition.<\/p>\n\n<p class=\"wp-block-paragraph\">The key is <strong>to know the condition of the roof before the problem appears<\/strong> .<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">The end of summer offers a good opportunity to check roofs and terraces, detect weak points and have time to fix them before the rainy episodes of the following months.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">At <strong>IMPERA<\/strong> we have experience in waterproofing, rehabilitation and maintenance of roofs of different types, from residential buildings to large industrial areas.<\/p>\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n<p class=\"wp-block-paragraph\">Taking timely preventive action can help extend the useful life of the roof, reduce the risk of leaks and avoid more complex interventions in the future.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The end of summer is a good time to check the condition of roofs and terraces before the arrival of the autumn rains .
