All you need to know about the costs associated with having your roof tiles treated including materials, labour and time frames.
When hiring a professional roof coating/tile painting company the first step will be an initial site survey to check access to the roof and ensure the roof tiles are suitable for painting. The general condition of the roof will be checked too for safety reasons. Then the job will entail the setting up of the safety equipment such as scaffold towers or harnesses and roof ladders. Covers and tarpaulins will normally be placed over patios and flowerbeds to protect them and any broken or damaged roof tiles will be replaced. The roof will firstly be washed but before this the gutters will be removed from drainage pipes to prevent the muck from the roof blocking the drains. Once roof tiles have been pressure washed and all roof moss removed, the tiles with a fungicidal wash and two coats of roof coating are applied.
If you are considering having roof tile treatment, then there are some other related jobs you may consider doing at same time. For example, any broken or damaged roof tiles should be replaced before any roof coating or painting is carried out. In addition, you should also consider any other jobs that require scaffold at roof level, as you will already be paying for this so may as well make full use of it and take care of other minor roof repairs at the same time!
Roof coatings are coloured paint which help to seal the tiles and they are usually applied to improve the aesthetics of the roof. However, much like the painting of exterior brickwork, once you have done the job once, you need to continue repainting it regularly, though most paints/coatings should last 6 to 8 years. Though the job is mainly done for visual appeal, the roof will be thoroughly cleaned and have a fungicide applied as part of the job, so it will help if you experience a lot of moss growth and may even help to reduce leaking gutters with a better flow off the roof and no moss leading to blockages and overflows.
These types of paints/coatings should be applied to roof tiles in winter or during damp conditions as they may not cure properly. It is best to wait for the warmer, dryer weather in the summer months. Remember that a roof coating can make old roof tiles look much better, but is no substitute for a new roof if the tiles are well past their prime. In fact, if the roof is in poor condition, reputable companies will refuse to apply a coating and risk their reputation.
The average cost to clean and coat a roof is typically around £1500-£2000 for a semi detached house with a gable roof. This price includes the roof being power washed, treated to prevent moss and two layers of coloured sealant applied. This average price can vary greatly depending on location, ease of acces, size of house, roof type, tile type and if a small or large company carry out the work.
A roofer will often charge around £150-£200 per day to coat a roof. Tradesmen will likely work in pairs in order to complete the job for safety precautions as well as to get the job done faster, as such you should expect to pay around £250 per day in labour costs. Day one usually starts with any required remedial work as well as cleaning and then applying the fungicide. Day two would then be coating the tiles with the coloured paint/sealant. Once the first coat is dry a second coat can be applied.
