Roofers in Seaford

1.1 Fixed for the position, not the postcode

Wienerberger's guidance is that no tile of the single-lap type goes up without a mechanical fixing, and that the fixings follow a written specification drawn up for that site, with its location, altitude and wind exposure all weighed. We follow that logic on repairs as well as new work. Slope angle changes the picture. Marley's point is that a pitch under 30 degrees leaves the slope meeting the wind open to strong negative pressure, so a low garage or rear extension may work harder than the steeper roof beside it. Each slope gets its own look for slipped tiles, rusted nails and clips that have loosened.

1.2 Ridge, hip and verge

Wind gets under the top edge of a roof first. The ridge runs along the summit where two slopes meet, a hip slopes down a corner, and the verge is the sloped edge that finishes against a gable wall. BS 5534, revised in 2014, stopped treating a mortar bed as enough for ridge and hip tiles, which must now be held by a fixing of their own. Mortar remains legal and still dresses the joint neatly, but it no longer carries the load alone. Dry-fix systems tested to BS 8612:2018 skip the mortar and rely on clips. We choose between them after seeing how sound the old ridge is and how much weather the slope takes.

1.3 What we put in front of you

From ladders and from inside the loft we photograph ridges, verges, valleys and the gutter line. Those pictures go into the written quote, which carries a single total price, so the cracked bedding or corroded nail is visible on your own roof. On the exposed side we record the eaves too. A gutter that sags or has lost its fall overflows against the wall, and the stain it leaves on the wall is easily pinned on the slope above. When a small repair cures the leak, that is what we recommend. Our ridge tile repairs and pitched roofing pages go into more depth on the options.

3.1 Where building control comes in

The Planning Portal sets out two limits for re-covering, shown in the table that follows. Go past either, add structural alterations, or lay a covering 15 per cent heavier or more, and an application is required; Part L can also demand better insulation when the work is large. Concrete tiles on a roof built for something lighter is the usual trap. Either route works: the council's own team, or a private approver on the register. We deal with the notification when one is due. During a strip we also look at underlay and eaves airflow. For a cold roof under high-resistance underlay, Marley gives 25 mm along the eaves at 15 degrees or below, and 10 mm above that.

3.2 What moves the price

Pitch, size, access, the covering you pick and the state of the timbers below it all swing the total. MyBuilder's guides, updated 21 August 2026, give £5,000 to £8,000 for a gable re-roof on a semi-detached house and £8,000 to £12,000 for a hipped one. Those are national figures, not our prices. Ours arrives as one total after the survey. Re-roofing attracts VAT at 20 per cent, the standard rate, and some quotes leave it out along with the scaffold, so read each one for both. When the job ends the scaffold is down and the debris gone. The roof replacement page follows a full job from first visit to final sweep.
