What Are Roofline Products?
Roofline products connect your roof to outer walls, protecting your home from water and weather damage while keeping the edges secure. Along with accessories like bargeboards, cladding and trims that cover corners and joints, roofline products primarily include:
- Fascias: Fascia boards run along the roof edge, parallel to the wall, providing a solid base for gutters and protecting the roof rafters.
- Soffits: Soffit boards, including hollow soffit boards and soffit vents, are installed beneath the fascia and along the rafter ends to provide ventilation.
- Guttering: Fixed to the fascia, gutters channel water safely away from your property, reducing maintenance while protecting foundations.
Correct installation of roofline products ensures the roof overhang and rafter ends remain shielded from moisture, pests and decay.

Posted on Google Ross MurrayTrustindex verifies that the original source of the review is Google. I’m very pleased with the work carried out by RePlace Windows. Last July, Scott came out to discuss exactly what I was looking for. He was friendly, respectful, and came across as genuinely honest and professional. He took the time to explain my options, the benefits of choosing RePlace Windows, and provided a very competitive quote. The following week, a technician carried out the survey, which took around an hour and was handled efficiently with minimal disruption. In September, the fitters completed the installation over two days. Although I can’t remember their names, they worked extremely hard, even staying into the evening to make sure everything was finished to a good standard. The windows look great. About a week later, someone also returned to repair the plasterwork, which I really appreciated. Scott then followed up afterwards to make sure everything had gone well — a great level of customer service that really stood out. I would happily recommend RePlace Windows to anyone looking for a professional, reliable, and considerate company.Posted on Google Jo MurrayTrustindex verifies that the original source of the review is Google. Just to say we recently had all of our windows replaced by RePlace and had an amazing experience! From the initial home visit with Scott to post installation, everything was great. We had only couple of minor snags (to be expected when replacing 13 windows) and the post installation customer service was impeccable! Quality products, competitively priced, excellent installation and super customer service. Huge shout out to the whole RePlace Team, this company knows what they're doing and I would highly recommend them to anyone considering new windows😁 https://www.replacewindowslimited.co.ukPosted on Google Carol MacKinnonTrustindex verifies that the original source of the review is Google.

I dont know how my name came up in the reviews of this company. I dont need windows or doors,Posted on Google Adam MackinnonTrustindex verifies that the original source of the review is Google. Kai and the team were great throughout the process. Windows installed are top qualityPosted on Google Kathleen DoyleTrustindex verifies that the original source of the review is Google. I had my windows replaced last week and the whole experience was excellent from start to finish. I highly recommend! Scott, the salesperson, was brilliant. He was friendly, straightforward, and there was absolutely no hard sell. After previous experiences of salespeople sitting in my house for two hours trying to wear me down, this was a breath of fresh air. The product genuinely sold itself, and Scott was in and out quickly, which I really appreciated. Communication throughout the process was consistently excellent. I was kept updated at every stage and always knew what was happening next. The fitters were great too — efficient, tidy, punctual, and really easy to feel at ease with in the house. They worked smoothly, respected the space, and left everything spotless. Overall, a genuinely positive experience and a company I’d highly recommend.

Our uPVC Roofline Installation Process
Our process is clear, simple and transparent:
Free quote: We assess your roofline, including existing fascia boards, soffits, soffit vents and supporting timber, then provide a detailed, no-obligation quote.
Safe setup: Using scaffolding, ladders or towers, we reach your roof efficiently while keeping your home and property safe.
Old board removal: Existing fascias, soffit boards, hollow soffit boards and guttering are carefully removed to inspect for damage and prepare a solid base.
Repairs: Any damaged or rotting timber is repaired or replaced to ensure your new UPVC fascia and soffit range sits securely.
uPVC roofline installation: We fit replacement fascia boards, soffit boards, vented soffits and cladding boards, securing them to ensure a durable, watertight finish.
Guttering Installation (upon request): We can also install new uPVC guttering to direct water away from the roof, roof rafters and outer walls.
Clean-up and final check: After installation, we clear the area of debris and conduct a thorough inspection to ensure your roofline is fully protected.
uPVC Roofline FAQs
Find answers to common questions about our range of uPVC roofline products here.
Although cladding an old wooden fascia with uPVC is technically possible, it isn’t ideal. Covering an existing board won’t stop moisture or leaks from affecting the fascia board or fascia soffits.
For long-term protection, we recommend removing the old timber and fitting replacement fascia boards. This ensures your uPVC fascia and roofline cladding perform as intended.
While capping boards can seem like a quicker, cheaper solution, they often trap moisture against existing timber, leading to:
- Hidden rot
- Warped fascia boards
- Long-term issues for your roof and house
Full replacement fascia boards are the ideal choice. By removing old fascias completely, we ensure your uPVC fascia, fascia soffits, soffit boards, and cladding sit securely, with the correct size and alignment.
We always recommend doing the job properly the first time around, as covering up problems with capping can create more issues than it solves.
The right uPVC fascia colour helps give your home a polished look while matching your fascia soffits and soffit boards.
Choose the perfect fascia colour that complements your property and your personal style:
- Black is ideal for a traditional or Tudor-style effect, giving your house a distinctive look.
- Brown mimics classic timber, bringing a natural feel and warmth to your roofline.
- Green creates a striking, natural accent for homes surrounded by gardens.
- Grey offers a sleek, modern aesthetic that complements contemporary cladding and window frames.
- Off-white shades, such as cream or pale gold, add subtle warmth, softening your home’s overall appearance.
- White remains the most popular option, offering a clean, versatile look that suits almost any house and pairs well with white window frames.
We keep pricing transparent and straightforward. Every quote clearly outlines the cost of materials and labour upfront, with no hidden fees. You only pay on completion, once you’re satisfied with the results, with no deposit required.
