Isn’t it better to hire a roofer?
Roofers are specialists who install or replace your roof covering in a professional manner. Your roof is a crucial part of your home and protects you from the weather and other external influences. Work on a roof must therefore really be carried out by someone who is familiar with it. Poorly done work can damage your home. A roofer also knows how to work safely, so that the work does not pose a risk for himself and for you as a customer. A roofer also offers a guarantee on his delivered performances, while if you cover your roof yourself, you should miss out on this guarantee.
Working safely above all else
If you are nevertheless keen to save labor costs, it is all-important that you think about your safety. Take measures to prevent the risk of falling. If you have a sloping roof and you are going to lug heavy roof tiles, the chance of falling is greater. So provide roof protection or fall protection.
A clean roof makes you work better
Also, make sure that the roof is in order. This means that the roof must be clean and dry. For example, with a wooden roof you have to check that protruding nails are removed, bad planks must be removed and curved planks must be planed. A concrete roof must be pretreated with primer to make the surface even.
A flat roof
A flat roof is never completely horizontal, otherwise, rainwater would not be able to flow away. So keep in mind that after applying the underlay you apply a slope of approximately one centimeter per meter, which runs towards the downspout to drain the rainwater.
The edges of your roof are finished with a fascia board, which mainly consists of solid plastic sheets. These fascias protrude approximately ten centimeters above the roof floor and you place them vertically on the roof edge. You nail the fascia boards to the edge beam. You place another plastic or wooden mastic scrap against the fascia, which you nail to the fascia. The mastic scrap serves to make the angle of the fascia less sharp.
Apply the undercoat
The underlayer of a roof covering can only be applied at temperatures above five degrees Celsius. You finish the edges with strips of one meter, using an overlap of approximately fifteen centimeters. You attach the individual parts to each other with a cold adhesive. You also attach them to the fascia every thirty centimeters with roof nails. After this, you place aluminum roof trims on the fascia boards. Work with pieces of up to two meters and place a stainless screw in the roof trim every forty centimeters. For the rest of the bottom layer, you roll out a roll from the lowest point and the bilge. You roll out the second job next to it, et cetera. The strips should overlap each other by about ten centimeters. To make the underlay waterproof, glue all seams and fix them with roof nails.
Flat rooftop layer
With a flat roof, you will often use EPDM roofing. Below is the procedure with this material. You lay the top layer again from the lowest point and from the bilge. Place the strips of the top layer in the same direction as those of the bottom layer. However, the top layer can be staggered half a lane by halving the first strip. Here too, an overlap of ten centimeters must be maintained and the strips must be fixed with roof nails. You also burn the top layer together with a burner. Do not burn until you have rolled out half the roll. Heat the roll evenly and across the width. This creates bitumen beads, in which you have to push the roll and press it well. This creates two new caterpillars at the ends and these prevent you from sticking diagonally.
It may be that folds occur in the bottom layer. You can prevent this by treating it with a primer before applying the top layer. Even if you opt for a liquid roof covering, you must first apply a primer. It takes about a day to harden. If you want shingles as a roof covering, make sure your roof does not have a slope less than fifteen degrees. Before placing shingles, it is advisable to apply a bituminous underlayment on your roof.
Top layer roof tiles
If you are going to lay roof tiles on your pitched roof, make sure that you first place counter battens vertically on the rafters. You must attach the rafters well to the shelter. In this way, you form a frame, as it were, in which you will lay the roof tiles. The horizontal slats keep the roof tiles in place because they are hung from these slats. The distance between them must be large enough for the roof tiles to overlap. How the roof tiles overlap depends on the type of roof tile, the method of hanging the roof tile, the slope of the roof, and the weather. You have to place the first batten slightly above the gutter because then the roof tile will be higher and it cannot fall into the gutter.
Laying roof tiles
When laying the roof tiles, you have to work from the bottom up and, depending on the roof tile type, in a fan shape, because that way you maintain an overview. Make sure that the bottom roof tiles are well anchored to the bottom batten. Secure the top layer of roof tiles securely in the ridge with stainless screws. Periodically anchor roof tiles against severe weather. The extension edge at the place where the roof borders the wall you have to seal with sheet lead.
