Question:
I am planing to fit this on top of 18mm marine ply on a lean to roof against the outside wall of the house. Can you please tell me how would I seal the join between the corrugated roofing and the wall of the house?
Answer:
To seal the join between the Coroline Green Corrugated Bitumen Roof Sheets and the wall of the house, you can use a combination of flashings and sealants. Flashings, which are pieces of waterproof material, are installed at the intersection of the wall and the roof to prevent water ingress. You'll need to cut and shape the flashing to fit the contours of the corrugated sheets and then secure it in place using appropriate fixings. After installing the flashing, you can apply a waterproof sealant along the edge where the flashing meets the wall and the roof sheet to ensure a complete watertight seal. Always ensure you're using a sealant compatible with bitumen materials. Please note that it's important to install the sheets correctly to maintain the 15-year waterproof guarantee. You might find our installation guide helpful for this process. However, for specific installation advice and procedures, it's always best to consult with a roofing professional.
Question:
Previously used ridge on coraline sheets About to replace roof 1. What is difference (in purpose etc) between ridge and verge (picture on web looks like verge would do the job just as well 2. Can they be laid over top of existing coraline sheets or do I have to remove existing (think of the fixings on existing sheets)
Answer:
Response: 1. The Coroline ridge and verge serve slightly different purposes in roofing. A ridge is designed to cover the peak of the roof, where two slopes meet, offering a neat finish and helping to keep water out. A verge, on the other hand, is used at the edge of the roof (where the roof meets the gable end) to protect the roof covering from wind uplift and to provide a clean, finished look. While they may seem similar in appearance, it's important to use the correct piece for its intended purpose to ensure the best performance and longevity of your roof. 2. As for laying new Coroline sheets over the existing ones, it's generally not recommended. While it might seem like a time-saving solution, you may encounter problems. The existing fixings may interfere with the correct placement of the new sheets, and the extra weight could put undue strain on the roof structure. It's usually best to remove the old sheets before installing the new ones. However, every case is different, so it might be best to seek advice from a roofing professional to assess your specific situation.
