About waterproofing and roofing contractors in Malta

Roofs in Malta are usually flat concrete, and they take a beating from the summer sun and heavy autumn downpours. Waterproofing contractors seal roofs, terraces and balconies with bitumen membranes or liquid polyurethane and polyurea coatings, and some also treat basements and retaining walls. Roofing contractors fit lightweight sheet roofs over pergolas, sheds, yards and car ports.

The time to book is late summer, before the first heavy rain. Cracks open up over the hot months, old membranes lift at the edges and roof drains fill with dust and leaves. Once a leak shows indoors, the water may have travelled under the old layer from somewhere else, so finding the source is part of the job.

Price depends on the roof area, the state of the old layer and whether it must be stripped, the system chosen, the detailing around parapets, drains, water tanks and solar panel frames, and access for materials. Roof sheets are priced on the type of sheet, the span and the frame. Ask for the system, the coats or layers and the guarantee in writing.

Questions

How much does roof waterproofing cost in Malta?

Contractors usually price by the square metre, but the rate moves with the system, the condition of the existing roof, how much stripping and repair is needed and how many details there are around drains and fixtures. A price list online rarely includes the preparation. Ask the contractor to inspect the roof, then get a written quote that names the product, the coats or layers and the guarantee.

Is a membrane or a liquid coating better for my roof?

Both are used on Maltese roofs. Bitumen membranes come in rolls and are torched or bonded down, with overlapping joins. Liquid systems such as polyurethane and polyurea go on as one continuous coat, which can make it easier to seal around pipes and fixtures. Each suits different roofs, budgets and uses. Ask each contractor why they recommend their system for your roof, and compare the guarantees.

Do waterproofing contractors work in Gozo?

Ask each contractor directly. Roofs in Gozo face the same sun and storms, and older houses with traditional roofs need extra care, so ask whether they have worked on that kind of roof before. For a job across the channel, check whether materials and travel are in the quote, and how they handle weather delays, since coatings need dry days to cure.

How do I check a waterproofing contractor?

Ask to see roofs they waterproofed a few winters ago, not last month, because a good job proves itself over time. Ask which product they use and whether the maker trained them to apply it. Get the guarantee in writing and keep the invoice with it. Tminta does not vet contractors, so read reviews and compare quotes for the same system.
