What does a survey include?

A commercial roof survey is a detailed evaluation of your roofing system carried out by a member of Allbase Technical Services. The process involves a comprehensive inspection to assess the roof’s condition, identifying any damage, leaks, or other issues. Using advanced tools and techniques, the survey gathers essential data to evaluate the roof’s performance. Following the survey, you will receive a detailed report that includes the findings, recommendations, photographic and video evidence with advice on any necessary repairs or maintenance.

Does a suveyor need liability cover?

Yes. while a surveyor does not undertake any roofing work they should still have the correct Public Liability Insurance cover just in case an accident were to happen.

How do you choose a roof inspection method?

The method used to inspect or survey a roof depends on factors such as roof type, condition, accessibility, and the purpose of the survey. Flat roofs may require close-up inspections, while drones or telescopic tools are ideal for hard-to-reach or pitched roofs. Visible damage might necessitate manual inspection, whereas sub-surface issues could call for thermal imaging or moisture detection. Safety and structural concerns often favour non-invasive methods, while compliance with regulations and the survey’s purpose, such as maintenance or insurance, influence the approach.

How much does a roof survey cost?

Every roof is unique, and the cost of a roof survey depends on various factors such as roof size, type, access requirements, and the scope of the survey. For this reason, we recommend filling out our online form at the top of this page with details about your roof. Once we receive your information, a member of our team will get in touch to discuss your specific needs and provide a tailored solution.

My roof is leaking and I need a solution fast?

Our team will evaluate the damage in detail and deliver a bespoke solution to restore your roof’s integrity. At Allbase, we offer a wide range of waterproofing systems but will only recommend the best solution for your specific project, rather than tailoring your needs to fit our products.

Do your roofing systems come with guarantees?

Our Basecare Guarantee Scheme provides up to 25 years of comprehensive protection, covering the waterproofing system, workmanship, and installation. This ensures complete peace of mind, from the quality of our products to the installation process through our contractor network and beyond.

How often do roofs need to be inspected?

It’s recommended that roofs should be inspected twice a year. The ideal times for roof inspections are after winter, around March, and before winter begins, around November, ensuring your roof and gutters remain in optimal condition.

Do I need a survey before installing solar panels?

The condition and suitability of your roof are critical to ensuring the effectiveness and efficiency of the solar panel installation. A roof survey will assess the structural integrity of your roof, identify any potential hazards or maintenance issues, and evaluate its ability to support the additional weight of the solar panels. It will also help determine the optimal placement and positioning of the panels to maximise sunlight exposure.
